Home building materials PPR pipe network elements
Home building materials PPR pipe network elements
PPR pipe officially called random copolymer polypropylene pipe, water pipe is home improvement projects.
PPR pipe interface using a hot melt technology, fully integrated in the tube, such a pressure test, once installed, never lose very reliable. However, this does not mean that the PPR pipeline pipe damage, a little 'high temperature resistance, pressure resistance, long running temperature not exceeding 70 DEG C, the length of each segment is limited, can not bend the construction, if the distance or angle necessary intake pipe, the pipe joint construction of the use of a large number of cheap, but the price relatively high part. The overall performance of the PPR tube is expensive, and it has become the favorite pipeline to improve the decoration material.
PPR pipe market there are three kinds of colors, white, green and gray, PPR and filler particles of raw materials are different between the results, why the dealer's answer. PPR tubes are green and white with the highest quality materials, gray, a little 'more than the time difference material.
Water in general, the reform will replace the existing pipeline, all pipes in the house with hot water and the proposed construction of the installation of PPR pipe, even in cold water, hot water pipes. They said that cold water pipes, hot water pipe stems, water pipes with water-saving transformation, technical parameters and price differences. Another fact is that if you want to buy cold water pipe market is also difficult to buy, because you are a single cold water market, rather than providing home improvement market.
Diameter PPR pipe diameter of 16 mm to 160 mm home improvement is mainly used for the 20 mm to 25 mm (commonly known as the six is responsible for) for further use, they are responsible for the four people in charge of the use of home improvement ().
In the first place, what is the PP-R tube?
PP-R pipe 3 is also known as polypropylene pipe, polypropylene random copolymer, through the catheter extrusion, injection molding parts. In Europe in twentieth Century, from the beginning of 90 years, the development and application of new plastic pipe products. PP-R is the use of the polymerization process in the late 80s of the late 20th century in the gas phase, making up about 5% of the total PE of the random molecular chain of polypropylene (random copolymer), a new generation of piping materials. Good impact resistance and long-term creep resistance.
PP-R, is there any connection with PP-C?
Some time ago, the local market, with PP-C, PP-R pipe and pipe fitting methods are consistent. Many people do not know, PP-R, PP-C, created a lot of misunderstanding and confusion. International standards for polypropylene, hot water and cold water pipeline stars PP-H, PP-B, PP-R, PP-C. In fact, the pipe market PP-C PP-B pipe, piping material of polypropylene resin block copolymer. PP-B pipe is hot and cold water pipes, the price is relatively cheap, heat resistance, pressure resistance, the difference between PP-R. For example, in the use of second conditions, the design pressure of 0.6MPadn25mm pipe, PP-R pipe thickness of 3.5 mm, 5.1 mm PP-B (PP-C); the design pressure is 0.8MPadn25mm PP- may use "the thickness of 4.2, PP-B (PP-C) from the thickness, because the required thickness is too thick and the size of the market structure is PP-R PP-C pipeline the same, using much less, must not be confused with the use of PP-R pipe, can under certain conditions, can not use the alternative design temperature of polypropylene PP-R pipe pipe C shown in Figure 2 to 70 DEG C water condition.
What are the characteristics of the PP-R tube?
In addition to the general plastic, light weight, did not form a scale, long live corrosion resistance and other properties, but also has the following main features: non-toxic, sanitary fittings, PP-R pipe. PP-R molecules only hydrogen carbon material, there is no harmful toxic elements exist, the health can not be used pipe can also be used for hot and cold water clean drinking water system.
2, heat preservation and energy saving. PP-R tube thermal conductivity 0.21w/mk, only for steel pipe 1/200.
Third, better heat resistance. VEKA PP-R softening point. Maximum operating temperature up to 95 DEG C under hot water system to meet the requirements of building codes.
4, long service life. Working temperature PP-R pipe 70 DEG C, working pressure (PN) 1.OMPa conditions, life of up to more than 50 years; up to 100 years, at room temperature (20 degrees C).
5 installation, easy connection can *. PP-R has a good welding performance and the furniture mix melting joint can be connected conveniently by virtue of the pipe connection part.
6 recyclable materials. PP-R pipe production washing, crushing and recycling waste. The total amount of recycled material does not exceed 10%, without affecting the quality of the product.
What is the main purpose of the PP-R tube?
1, cold and hot water systems, including central heating system;
2, heating systems in buildings, including floors, walls and floor radiant heating systems;
3, pure drinking water supply system;
4, the central air-conditioning system (medium);
5, the transfer or release of chemicals in the industrial pipeline system real estate agent.

What are the specifications for welding PE pipe fittings
PE pipe manufacturers in the welding system, the requirements are particularly high, because if the improper construction will cause a large number of products gradually broken.
First, each welded pipe in the construction of a masonry well and concrete base to prevent the displacement of the fracture. Second, the trench bottom should be smooth, usually with a diameter of not more than 50mm without sharp stones and mixed material of sand and clay, flat bottom, gully density should be at least density reached around the landfill materials. Third, each pipe must be flat in the ditch, because the welded pipe fittings will have 1 - 3 different manual welding mouth, if the placement is not level, the bottom is not good, the stress will cause fracture.
In addition, the welding pipe fittings and the backfill on both sides of the pipeline is very important, backfill should be symmetrical, layered, each layer of about 30cm, according to the requirements of compaction, in order to prevent displacement, layer by layer compaction.

PPR pipe fittings whether or not simple discrimination
PPR pipe fittings whether or not simple discrimination
A coin can be used to distinguish the good and bad, the following on the PPR pipe manufacturers to introduce. PPR pipe, also known as type three polypropylene pipe, that is, hot and cold water pipes, is essential for the public home improvement. The current market on the real PPR pipe fittings imported from abroad, the price is higher, a ton of about 12 thousand. PPR pipe has the characteristics of light weight, corrosion resistance, non scaling, long service life and so on. In order to reduce costs, some businesses produce PPR pipe, only 800 yuan per meal to participate in calcium carbonate. This product is easy to deformation, explosive tube, short life.
How to distinguish between true and false PPR fittings? Trick One: select the same two long PPR pipe fittings point to investigate the remains after incineration. The more pure the residue, the more impurities. Trick two: after 2004, a dollar coin, standard component is 6 grams." Take a one dollar coins on the side, then the PPR pipe intercepted a small piece, weighing on the electronic weighing, and ultimately ensure that the test is 60 grams of PPR pipe, that is, the amount of coins of 10 times. Then, cut a small hole in the PPR tube and clip the coin. Put the coins in the PPR pipe in the water, PPR pipe floating in the water. "This PPR pipe is true." If the PPR pipe submerged in the water, then the PPR tube must be mixed with impurities such as calcium carbonate. Principle: the proportion of water is 1, the proportion of authentic PPR pipe between 0.90~0.91, will not sink into the water. The proportion of calcium carbonate is more than 2.7, once incorporated into the PPR tube material, will increase the proportion of. They experimented many times, and the weight ratio of PPR fittings and coins was 10:1. On the water, authentic PPR tube will not sink.

In addition, the district should be symmetrical layered backfill, not unilateral backfill. In the use of time, we must pay attention to the unilateral side of the ban
These operations can prevent the PPR pipe fittings appear continuous floating and hot deformation phenomenon, and we in the purchase, in fact should understand these problems.

Introduction to the deformation of PPR parts
Introduction to the deformation of PPR parts
The deformation of PPR pipe is a pipe size changes when ambient temperature changes, the general material has the natural attribute of expansion and contraction.
Select the PPR pipe by welding process, mechanical properties and comprehensive properties of materials, enhances the heat and strong cold deformation performance, thereby reducing the thermal expansion and contraction phenomenon. Linear expansion coefficient of length variation of thermal deformation of pipe fittings. Because of the low temperature in winter, the PPR pipe of home improvement is easy to accept the low temperature, so the welding process is generally used to reduce the thermal deformation of the pipe material. The ability of the material to resist the external force is called bending, tensile, anti - compression and other strength. The mechanical properties of PPR pipe, mainly refers to the nature of the pipe under the load, the ability to resist the destruction and deformation of high and low temperature.

Problems existing in PPR pipe arrangement
Problems existing in PPR pipe arrangement
Many consumers found that their home installed PPR pipe problems, which affect the use of water pipes. So, PPR water pipe construction layout of the common problems?
Water pipe joint, the pipe looks very normal, in fact, there is a big problem. This toilet is changed by the water hot and cold water, add a lot of water in the joint, is bound to stay hidden for the day after Water Leakage so has the following requirements in the construction of PPR pipe layout:
First, buried in the wall of the pipeline can not have joint; second, the pipeline must be smooth after treatment by the waterproof groove arc;
Third, the fixed point should use special clamp.
PPR pipe and the top surface is not fixed, PPR water pipe in the top surface must be fixed, in accordance with the regulations, should be separated by a fixed point of 50 cm. Second, the bulb is too close to the risk of being baked. In addition, the construction should ensure that the closure of the upper reaches of the household toilet water acceptance;
The hot water pipe and wire pipe not tightly connected, except water wiring buried in a wall part has no fixed interface, using special clamp, hot water pipe and wire pipe tightly together, easy deformation caused by short circuit;
Normal use, the electric wire pipe and hot water pipe have heat release, so the two kinds of pipes should keep a certain distance, so as not to heat deformation of the pipeline, resulting in short circuit.
When laying water pipes must be horizontal and vertical, because the laying of water pipes are not standardized, did not do a horizontal flat vertical, the results of the follow-up workers to operate the water pipe leak accidentally;
The laying of water pipelines must be horizontal and vertical, let the following workers can master the pipeline trend in the construction, avoid wearing. In addition, there is no need to check the ground line is prohibited in the drilling "mark before the construction of underground pipelines, so as not to break. In addition, the construction should pay attention to the water inside the tube, once the break can be found in a timely manner; if the completion of the opening of the main valve was found to be leaking pipe, resulting in greater losses.
After installation shall test the water pressure test, pressure test, the main health plug leakage occurred Water Leakage phenomenon; according to the regulations, after the water pipe laying, must pass through the pressure test, the test is not Water Leakage to normal use. Hit 8 - 12KG of air pressure, air pressure to maintain at least half an hour before being qualified.

What are the requirements for PPR pipe welding quality?
What are the requirements for PPR pipe welding quality?
First, we must choose the quality of qualified hot melt welding machine.
The temperature control to correct. PP-R hot melt welding temperature: 253 -274. If the temperature is below 253 DEG C, the fitting and the pipe is only a thin surface layer of the melt, once between them for welding, the welding strength is not guaranteed, this is what we usually call the phenomenon of false welding; on the contrary, if the temperature is above 274 DEG C, molecule on the surface of pipe and pipe fitting was high the destruction of the PP-R formation of thin liquid, the connection will make the pipe diameter smaller PVC pipe manufacturers to remind the more important is that connection will occur brittle fracture, especially in the pipeline system completed after water pressure, often happen in this kind of problem.
The temperature will take a long time. The length of constant temperature is one of the important signs of the performance of hot melt welding equipment. Hot melt equipment, there is still a problem in energy consumption of heating to the set temperature, especially in winter, the air outlet, even in the non working gap, the heat consumption is great, and once during the operation, the pipes and fittings are respectively heat energy consumption, which requires a strong heat storage equipment ability and replenish ability.
Two, must choose qualified and suitable welding sleeve.
In the design, the qualified welding sleeve is fully considered the transverse structure and depth of welding, and the surface is not sticky and surface finish. At present, the domestic production of hot melt welding PP-R, PPC, PE and other manufacturers have hundreds of water pipes. Because of the various manufacturers of raw materials used in the production of pipe, different additives, different environmental conditions, different equipment, making the production of the pipe and pipe sizes are not the same. Therefore, the manufacturers and users of various pipe manufacturers must choose the suitable welding sleeve for the diameter of the pipe. For operators, after the final welding should be necessary to clean the surface of the welding sleeve, so as to avoid the welding part of impurities.
For more than 40mm diameter pipe welding, due to the larger caliber, non personal strength can work, must use mechanical equipment to ensure that the pipe into the pipe depth and straightness. We found that in many sites with five to six workers on a 110mm caliber welding interface, cost tremendous effort can not guarantee the pipe straightness and the insertion depth, the entire pipeline winding, it is difficult to imagine in a certain temperature and pressure condition.
Three, hot melt welding prone to problems.
It should be said that in strict accordance with the welding process and welding technology requirements of the construction operation of the pipeline system, the use of normal temperature and pressure will not have any problems. But in our daily construction is often found in burst phenomenon or will trachoma in connection pipe and pipe fitting.
The main reasons are as follows:
The temperature of hot melt welder is not correct, too high or too low, the change of the properties of polypropylene;
The welding surface does not handle well, shedding or surface coating and the pipe part makes contact hole;
The welding set the wrong size, design right, the melting depth and weld pipe connecting structure is not appropriate;
The welding of pipe before welding surface cleaning;
The welding pipe and pipe fittings not maintain concentric or straight line.
Four, the correct welding procedure.
The hot melt weld preparations
The 25-110mm diameter pipe to the pipe chamfering device port half chamfer angle of 15 DEG to the original pipe wall thickness;
Clean the surface of the welding part of the pipe with a cleaner (or alcohol) and a brush;
When the pre assembled parts are welded, the connection is made on the position of the pipe and pipe fitting.
The 40mm caliber above must use the plane and vertical pipe welding welding machine;
Every time the dissolved, should use dry cloth or paper to wipe the heating cover and the heating head, do not use cleaning agents.
The hot melt connection and
After the pipe and the pipe are respectively inserted into the heating sleeve and the heating head, do not rotate or move too fast.
After heating, remove the pipe and fittings from the heating element.
Immediately after heating pipe and fittings along the axis pressure, do not rotate. Strictly adhere to the hot melt welding standard holding time and cooling time.

PPR pipe material and ppb material distinction
For the real PPR pipe, it is not only the use of PPR material, but also the use of PPB material production, but the ppb material is the production of cold water pipes, PPR material is the production of hot water pipes.
PP material is a kind of ethylene glycol copolymer PP-B, which is one percent to four percent, which is an irregular copolymer PP-R or a higher ratio of ethylene content. The strength of PP increases with the increase of ethylene content.
With the increase of ethylene content, the softening temperature of PP materials will also decrease, resulting in PP-B material load softening temperature usually at 90 degrees Celsius, if the PP-B material for hot water pipe, the use of a certain period of time after the pipe will occur irreversible thermal expansion, and even lead to bending deformation. Buried pipe wall arch cracking. The PPR VEKA softening temperature above one hundred and thirty degrees Celsius, the normal family in the use of the process is not obvious bending deformation, we can rest assured that long-term use. So hot water pipes must use PPR material to produce.

Characteristics of PPR pipe fittings
Characteristics of PPR pipe fittings
There are many uses of PPR pipe fittings, at the same time, it also has many characteristics:
First of all, because the raw material of PPR is only carbon and hydrogen, there is no harmful and poisonous elements, so the PPR pipe has the characteristics of non toxicity and sanitation. Second, it has heat preservation and energy saving, and good heat resistance, can meet the requirements of building water supply and drainage system in the use of hot water systems. Third, it has a long service life, can be used for more than 100 years at room temperature. Fourth, it is easy to install, reliable connection, the strength of its connection is greater than the strength of the pipe itself. Finally, the material can be recycled, saving resources.
These are the characteristics of the PPR pipe fittings, I believe we can have a better understanding of.
