1、 Product introduction
PVC-U drainage pipe is made of health grade polyvinyl chloride (PVC) resin as the main raw material, adding appropriate amount of stabilizer, lubricant, filler, colorant, etc. it is extruded by plastic extruder and injected by injection molding machine, and the production of pipes and fittings is completed through cooling, curing, setting, inspection, packaging and other processes. It has excellent physicochemical properties, chemical corrosion resistance, high impact strength, low fluid resistance, 30% higher flow rate than cast iron pipe with the same diameter, aging resistance, long service life, and service life of no less than 50 years. It is an ideal material for building water supply and drainage.
二、性能特点
1, strong corrosion resistance, not affected by corrosive soil and all kinds of drinking water;
2, the inner wall is smooth, less friction resistance than conventional materials;
3. Pipes and fittings will never rust, so there will be no change of erosion and contraction inside;
4. The exterior wall of the building will never be polluted due to the rust of the pipeline, so as to ensure that the value of the building will not be damaged;
5. Piping fittings are of various styles and complete, which can be suitable for various design and installation requirements;
6, convenient installation, no need for regular maintenance;
7, the weight of cast iron pipe is 1/5, easy to transport and operation;
8, the use of glue bonding, simple and fast, economic and efficient;
9, tasteless, non-toxic;
10, resistant to a wide range of chemicals, including strong acids and alkali;
Not affected by bacteria;
12, termite resistance, weathering resistance;
13, lower price than conventional materials;
14, under normal use conditions can reach more than 50 years of life.

Four, the installation method
1, PVC drain pipe diameter is greater than or equal to 100 mm of pipe generally use apron interface;
2, PVC drain pipe diameter is less than 100 mm of the pipe is generally used in bonding joints, and some use live joints;
3, PVC drainage pipe pipe across the sewer or other pipes, generally use metal pipe, then the plastic pipe and metal pipe with flange connection, the valve before and after the connection with the pipe is also the use of flange connection.
