Characteristics and main uses of several Plastic Pipes

Comparison of the characteristics and main uses of several commonly used Plastic Pipes

The characteristics of PVC pipe have good tensile and compressive strength, but its flexibility is not as good as other plastic pipes, and its corrosion resistance is excellent. Rubber ring connection and flange thread connection are mainly used for water supply and drainage, irrigation, gas supply, exhaust pipes, wire conduits, rainwater pipes, industrial anti-corrosion pipes, etc. in residential life, industry and mining, and agriculture.

CPVC pipe Features outstanding heat resistance, heat distortion temperature of 100 ℃, excellent chemical resistance Connection method bonding, flange thread connection Mainly used for hot water pipes

PE pipe features light weight, good toughness, good low temperature resistance, non-toxic, low price, high impact strength, but low compressive and tensile strength Pipes, rainwater pipes, gas pipes, industrial corrosion-resistant pipes

PP pipe features good corrosion resistance, good strength, high surface hardness, surface finish, and a certain high temperature resistance Connection method Hot melt welding, flange thread connection is mainly used for chemical sewage, seawater, oil and irrigation pipes for indoor concrete floors as heating pipes for heating systems

ABS pipe features excellent corrosion resistance, light weight, higher heat resistance than PE and PVC, but more expensive. Connection mode bonding, flange thread connection Mainly used for sanitary ware sewer pipes, transportation pipes, sewage pipes, underground cable pipes, high anti-corrosion industrial pipes, etc.

The strength of PB pipe is between PE and PP, and the flexibility is between LDPE (LDPE: low density polyethylene) and HDPE (HDPE: high density polyethylene). Its outstanding features are creep resistance (cold deformation), repeated Continuous winding, good temperature resistance and good chemical performance

GRP pipe Excellent corrosion resistance, light weight, high strength, good design performance Connection mode socket rubber ring connection, flange connection is widely used in petrochemical pipelines and large-diameter water supply and drainage pipelines

How to identify PP pipe?

1. "Touch": Whether the texture is fine and the particles are uniform. At present, PPR pipes on the market mainly have several colors of white, gray and green. Generally, recycled plastics cannot be made into white, so consumers often think that white is the best. In fact, this view is relatively one-sided. With the update and improvement of technology, color is not the standard to distinguish the quality of PP-R tube. Whether the tube is good or bad, it seems that it can't solve the problem. If you touch it, the rough particles are likely to be mixed with other impurities.

2. "Smell": with or without odor. The main material of PP-R pipe is polypropylene. Good pipes have no odor, and bad ones have a strange smell. It is likely to be blended with polyethylene instead of polypropylene.

3. "Pinch": The PP-R pipe has considerable hardness, and it can be easily pinched into a deformed pipe, which is definitely not a PP-R pipe.

4. "Smashing": A good PP-R tube has good "resilience", and it is not a good PP-R tube if it is too easy to smash. However, strong hardness does not mean good elasticity. Consumers will have doubts about PP-R pipes that cannot be broken. Because some unscrupulous manufacturers increase the hardness of pipes by adding too much calcium carbonate and other impurities, such pipes are prone to brittle cracks after a long time.

5. "Burning": It is very intuitive and effective to set it on fire. The PP-R pipe mixed with recycled plastic and other impurities in the raw material will emit black smoke and have a pungent odor; good materials will not emit black smoke and odor after burning, and the molten liquid will still be very clean after burning.
