Reason:
Basic knowledge of 1 and PVC-U pipeline.
PVC-U pipes are made of sanitary grade polyvinyl chloride (PVC) resin as the main raw material, added with appropriate stabilizers, lubricants, fillers and colorants, extruded by plastic PVC-U drainage pipe extruder, injection molded by injection molding machine, cooled, solidified, shaped, inspected and packaged to complete the production of pipes and fittings.
2. Performance characteristics of PVC-U pipeline.
① Excellent physical and chemical properties, chemical corrosion resistance, high impact strength, low fluid resistance, 30% higher than that of the same caliber cast iron pipe, aging resistance, long service life, and service life of not less than 50 years. It is an ideal material for building water supply and drainage.
(2) Lightweight and durable, easy to install, effectively speeding up the progress of the project.
(3) Save the construction cost, which can be greatly reduced compared with the cast iron pipe of the same specification.
Patented pipe fittings-advantages of leak-proof embedded pipeline connection
1. When the floor slab is poured, an anti-leakage groove is embedded in the concrete, so that cracks will not be formed and water leakage will be avoided;
2. The anti-seepage angle forms a posture close to the pipe wall, which can prevent the water in the pipe from leaking outwards due to uneven gluing;
3. The anti-skid nail hole can accurately fix the product in the expected position and will not move with the construction collision, thus ensuring the beautiful installation of the pipeline in the future;
4, dust cover to prevent concrete from entering the embedded direct inner wall, to avoid the difficulty of pipeline installation, but also to prevent debris from entering the first installed pipeline and causing pipeline blockage in the future.
