PVC Pipes

What you need to know about PVC pipes. PVC – a polymer commonly used in engineering and construction. Typically used in manufacturing plastic pipes and windows, or not plasticized form, being named rigid PVC, for production here and there to keep the old Soviet term "vinyl plastic." Positive properties characteristic of PVC, and causing its wide use – low flammability and good chemical resistance to aggressive media, at a relatively low price. PVC is less sensitive to UV light. What consumer need to know about PVC pipes? If plastic pipe or HDPE pipe you have not flowed through fifty as promised warranty and five years later, the fault lies, as a rule, not the pipes, and install them in public – error during installation. Most likely not taken into account neither the quality nor the pipe material, and an incentive to install tubes in the solution was only then that these pipes are made of plastic. Even good quality PVC pipes, improper (brand, size, etc.), can you break down prematurely.

The technology requires the installation fitters observe certain rules, and mounted without compliance pipelines are not long. You can not buy a plastic pipe to check by inserting into each other, if the box is a rubber seal. After all, the pads will still is airborne dust and dirt, with the introduction of PVC pipe a few times will damage these most rubber seals. A good installer before installing the pipes and gaskets will wash the dirt and dust, and then their smazhetsya petroleum jelly. On some tubes are chamfered, it should be removed. The rubber ring on the tube to compensate for mismatch between the axis of the joined pipe parts, and that this differential shrinkage of the sealing-ring belt is the cause of the marriage, resulting in leakage of the connection. Rubber seals are necessary and to compensate for the thermal elongation of the plastic tube. When assembling the bell-mouthed pipe connections rubber seal left a gap between the edge and the base – a smooth end of the tube and put on his chute.

As you know, in our sewer pipes enter the aggressive alkaline effluents. Yes, believe me, this is precisely chemical characteristics of a flow from your washing machine and dishwasher. And the temperature of the effluent reaches 90-95 C. Because the pipe for sewer should carry such an environment and its impact. Thin-walled PVC pipe for This does not fit, do not break down and quickly breaks down. To facilitate your choice of a standard ISO 3633, in which all polymer pipes are divided into types: type "A" – pipes for ventilation, for internal storm pipeline, type "B" – pipes and distribution system for discharge of sewage and wastewater flows. When buying tubes guided by these standards, and just remember that the pipes are of type "A" have thinner walls. Accordingly, the price them lower. Installation of sewer system itself is usually started when they met (pierced), all holes in walls, Stroebe, and niche overlap. Lots of walls, where the pipeline will be opened, you plastered, dig through the finish trench for the issue, if installation takes place in an individual building. Complete all work where possible to use an open flame. Installation begins with the issue, then going risers. Strut mounts from the bottom up, and only then starting to make a cross strut, and mounted taps sewers. All elements of the sockets are directed strictly towards the flowing stream discharge. Observe the slope for all sections of the pipeline.
