Welding repair method of PVC drainage fittings

Welding repair method of PVC drainage fittings
PVC drainage accessories if there is water leakage, you can choose to use the welding repair method. In the welding time to pay attention to ensure that the welding parts dry, while cleaning the surface of the dust, oil and other oils and fats, in the bonding interface welding repair, the adhesive must be removed clean welding.
PVC drainage parts Road and pipe fittings in the structural safety conditions do not affect the slight leakage, can be used PVC-U welding repair welding, ambient temperature is not less than 5 degrees celsius. Using multi-layer welding, to cool down after a period of time, and then the next layer of welding. Welding, the need to maintain appropriate temperature and pressure, the hot air temperature should be 260 degrees Celsius -290 degrees celsius. Overheating is easy to deform or carbonization, and the pressure is too high may cause the cracking of the weld after cooling.
If PVC is because the drainage fittings Dingfan apron or pipe to replace damaged pipe, the pipe should be cut off. The following 160 diameter pipeline, heat socket can be taken on-site repair, the two ends of the pipeline sawing up, both sides for chamfering. Interception of a replacement tube, will replace the ends of the tube after heating and insert cut off both ends of the pipeline and put into the ditch, then after cooling.
Flange fast docking, PVC road drainage fittings replacement parts cut ends hit groove. Take the joint four, the replacement of a section of the pipe. Four socket joints are sheathed in the two ends of the replacement pipe and cut off the PVC drainage parts at both ends, and the replacement of the set of socket joint and a good socket connector of the broken pipe flange connection.
The fast joint top double apron expansion or damaged oral sawing. Both ends of the broken pipe are sheathed with a movable sleeve flange and a rubber ring. The broken pipe flat back flange sleeve, the distance equal in broken tube ends, will looper flange and the flange sleeve with bolts.

PVC-U tube how to pass through the low-lying areas

PVC-U tube how to pass through the low-lying areas
The foundation of PVC-U pipeline must have enough bearing capacity and reliable stability, otherwise, the uneven settlement of foundation will cause the wrong port, fracture, leakage and other phenomena of PVC-U pipeline. For soft soil foundation, miscellaneous fill soil foundation and so on, should take the foundation treatment measures, can refer to the standard: "water supply and drainage pipeline engineering construction acceptance code" GB 50268. Specific design should be carried out by the professional design department to ensure the safety of pipeline operation. According to the specific circumstances should be done as follows:
1, the foundation pit filling layer paved bottom, upper part of the compacted layer, then laying concrete foundation beneath PVC-U pipeline trench.
2, PVC-U pipeline crossing the Gouyan parts should add transition protection measures, such as the use of multiple short 0.8-1.0 meters transition, or casing protection.

How to improve the efficiency of PPR pipe fittings drainage pipeline

How to improve the efficiency of PPR pipe fittings drainage pipeline
In the use of PPR pipe fittings, bonding before the test is to be assembled, today, small make up for you to introduce how to improve the efficiency of PPR pipe fittings drainage pipe:
First of all, after taking length determination in PPR pipe fittings, can be hand cut with a hacksaw saw or saw blade sawing, sawing machine. Then, each layer of vertical pipe expansion joint installed one, and to compensate the countercurrent tube expansion. Again, in the installation of three links to the attention of downstream direction, to facilitate the installation of horizontal tube when the natural slope of each storey riser within 3M, consider setting up a hoop. In addition, the horizontal pipe, drainage pipe line distance should be in line with the provisions, but also should be set to check the mouth or mouth cleaning.
Above is to improve the efficiency of PPR pipe fittings and drainage pipeline related knowledge, we hope to be able to help.

PPR pipe fittings construction completed testing standards

PPR pipe fittings construction completed testing standards
After the PPR pipe fittings factory construction is completed, it is necessary for its acceptance, every aspect should be in line with the standard, to ensure that it is safe to use.
1, it is necessary to conduct testing of each part, and look at the construction drawings are not consistent, or have not cut corners.
2, to check the PPR pipe pipe fittings have no debris, in order to avoid the water pressure test, the debris in the pipeline collision caused by cracks, if so, after the use of the process will occur.
3, but also to check the parts and equipment is not completely hot melt with the pipe, a lot of accidents are in the hot melt interface burst.
In addition, the PPR pipe fittings need to use the support of the support of the place, but also to check the stent is not stable enough and strong.
