6 kinds of plastic pipes commonly used in water supply and drainage engineering and their advantages and disadvantages

Ningbo Fangli Technology Co., Ltd. is a mechanical equipment manufacturer with nearly 30 years’ experiences of plastic pipe extrusion equipment, new environmental protection and new materials equipment. Since its establishment Fangli has been developed based on user’s demands. Through continuous improvement, independent R&D on the core technology and digestion & absorption of advanced technology and other means, we have developed PVC pipe extrusion line, PP-R pipe extrusion line, PE water supply / gas pipe extrusion line, which was recommended by the Chinese Ministry of Construction to replace imported products. We have gained the title of “First-class Brand in Zhejiang Province”.

Here, we’d like to introduce 6 kinds of plastic pipes commonly used in water supply and drainage engineering and their advantages and disadvantages as the followings:

I. Rigid  polyvinyl chloride (PVC-U) pipes for water supply （Non lead salt stabilizer）

PVC refers to polyvinyl chloride, and PVC-U refers to rigid polyvinyl chloride. PVC is a kind of plastic, which is harmful to human body because most of the lead salt is added in production. Only a small part of those without lead salt can be used as environmental protection water supply pipes for water supply.

Characteristic：

1） It has high hardness, stiffness and allowable stress.

2） Good aging resistance, durable and life span of up to 50 years.

3） Corrosion resistant, cheap, easy to bond, self extinguishing.

4） Recyclable, easy and simple installation and good sealing.

II. PVC-U pipe for drainage

PVC-U pipe is made of sanitary polyvinyl chloride (PVC) resin as the main raw material, added with an appropriate amount of stabilizer, lubricant, filler and color enhancer, extruded by plastic extruder and injection molded by injection molding machine, and completed the production of pipes and pipe fittings through cooling, curing, shaping, inspection, packaging and other processes. It is an ideal material for building water supply and drainage.
