The difference between PVC drain pipe and PVC line pipe

Both PVC drain pipes and PVC line pipes belong to PVC pipes, and they have similarities and differences. PVC drain pipes are mainly used for water supply, while PVC line pipes are mainly used in the power industry.

Conceptually differentiate:

The PVC pipe drainage pipe is made of sanitary polyvinyl chloride (PVC) resin as the main raw material, adding an appropriate amount of stabilizers, lubricants, fillers, color enhancers, etc., through extrusion molding by plastic extruder and injection molding by injection molding machine. , curing, shaping, inspection, packaging and other processes to complete the production of pipes and fittings.

PVC line pipe is a kind of white rigid PVC hose, which is anti-corrosion, anti-leakage, and used for wiring.

Distinguish from pipe diameter:

The diameter of the drain pipe is generally 50-75-110-160, etc.; the diameter of the line pipe is 16-20-32-40-50, and the small diameter is mostly.

Distinguish from application areas:

PVC drainage pipe is an alternative to traditional drainage pipes and has better physical and chemical properties. It has a smooth inner wall and lower frictional resistance than conventional drainage materials, so the installation slope of the transverse pipe is smaller, which can improve the indoor clear height of the building. PVC drainage pipe is light in weight, one-fifth of the cast iron pipe, easy to transport and operate; it adopts adhesive connection, which is convenient for installation and maintenance; the price is lower than that of conventional drainage pipes, which greatly reduces the project cost; strong corrosion resistance, in construction Sewage and stormwater piping systems are commonly used. The widespread use of PVC drainage pipes is conducive to saving steel, and is of great significance for alleviating the shortage of steel in my country. Compared with cast iron pipes and steel pipes, PVC-U drainage pipes have the disadvantages of low pressure and weak impact resistance. PVC Although the -U drainage pipe is a flame-retardant material, for indoor exposed pipes, there is a possibility that the fire will spread upward along the drainage riser.

PVC conduit is used in normal indoor environment and in places with high temperature, dust, vibration and fire hazard. Can also be used in wet places. It should not be used in places with extreme humidity, acid, alkali, salt corrosion and explosion hazard. The ambient temperature is -15℃～+40℃. Excellent mechanical properties of the threading tube. Excellent corrosion resistance, high compressive strength of threading pipe, working pressure over 2.5Mpa. The surface of the threading pipe is smooth, the fluid resistance is small, and it is not fouled and should not breed microorganisms. The thermal expansion coefficient is small and will not shrink and deform. Traditional installation and connection. The epoxy plastic coating of the threading pipe more effectively solves the corrosion of water transmission, burial and acid, alkali and salt to metal pipes, and the service life can reach more than 50 years.
