Is the heavier the PPR fittings the better?

PPR Pipe fittings such as PPR elbows or PPR tees are generally divided into all-plastic pipe fittings and copper embedded pipe fittings, so we will discuss the weight of the twoPPR pipe fittings separately.

First of all, whether it is all-plastic PPR pipe fittings or copper-inlaid pipe fittings, the PPR raw materials are used in the plastic part. The density of pure PPR raw materials is between 0.89g/cm³ -0.91g/cm³ . There are different PPR pipe brands and manufacturers due to mold design. Different, there are generally differences in individual size and weight.

Secondly, in addition to the PPR material, what determines the weight of copper-embedded PPR pipe fittings is the copper label and weight. The copper inserts of the PPR pipe fittings we produce are made of HPB62 high-precision brass one-time forging, 4 layers, and 8 processes are used. The material is very elegant, our ppr pipe fittings are obviously heavier than the PPR pipe fittings produced by other factories, and more importantly, the main component of the weight of the pipe fittings we produce is copper. We all know that the price of copper material is 5-7 of the price of PPR material Therefore, our ppr fittings have better quality and better materials.

What if PPR pipe fittings are produced from non-PPR raw materials, or if they are produced from non-pure materials? How to simply identify it?

It is difficult to judge whether the PPR pipe material is pure from the appearance or weight alone. The simple reference method is: ignite the pure PPR pipe fittings, which are not black and odorless, and can pull out a long round wire. If it burns, it will turn black. If there is a peculiar smell, and the long round wire cannot be pulled out, or the flat wire is pulled out, it means that the raw materials used in the PPR pipe fittings may be impure.

Generally speaking, if the PPR pipe fittings produced with pure raw materials are heavy, it means that more raw materials are used, and the safety of hot-melt welding is better. This is because the PPR pipe national standard for pipe fittings is mainly the socket standard There is no fixed standard for the individual size and weight of pipe fittings. The high-end home improvement PPR pipe brand represented by cleanliness pipes, in order to ensure that higher quality products are provided to users, are both in the design and size of PPR pipe fittings. Adhering to the consistent principle of transcending the national standard. However, the situation of PPR pipes is different. The length, wall thickness, and inner and outer diameters of PPR pipes have strict standards. Therefore, it can be said that if the weight of PPR pipes produced according to the standards is heavier, it may indicate that there are impurities in the pipes and other non-PPR raw materials, which may be more weight. There will be problems with heavy ones.
