Article Introduction
Everyone knows PVC pipes, and its advantages are obvious to all. PVC is cheaper than other polymer materials, has a wide range of raw materials, simple production process, certain insulation and flame retardant effects, and can be recycled and used. Everyone must know the drain pipe and the water supply pipe. Because of the advantages of PVC material, many water supply pipes and drain pipes will choose to use this material.
So what is the difference between PVC Plumbing Pipe and PVC Drainage Pipe ? Okay, through the following article you will understand.
What is the PVC water supply pipe?
The PVC water supply pipe is made of hygienic polyvinyl chloride resin as the main raw material, adding a certain amount of stabilizers, lubricants, fillers, colorants and the like. Through plastic extruder extrusion molding injection molding machine, through cooling, solidification, stereotypes generated by the water supply pipeline, inspection, packaging and so on. UPVC has excellent chemical resistance over the entire operating temperature range and has a wide range of working pressures.
Characteristics of PVC water supply pipe:
Light weight: easy to transport and install.
Corrosion resistance: can resist corrosion from a variety of chemicals and extend service life.
Small water flow resistance: reduce head loss and improve water supply efficiency.
Quick installation: convenient construction, saving time and manpower.
Low cost: compared with other materials, the cost is lower and economical.
Purpose of PVC water supply pipe:
PVC water supply pipe is mainly used to transport drinking water, and its pressure resistance range is between 0.63MPa and 2.5MPa to ensure water quality safety. The specifications of PVC water supply pipe range from dn20 to dn1200, and each specification corresponds to different wall thickness according to different pressure bearing capacity.
What is a PVC drain pipe?
PVC drain pipe is a drainage pipe made of polyvinyl chloride (PVC) material, mainly used in drainage systems to treat domestic wastewater, sewage and rainwater. PVC drain pipe has many advantages, including high surface hardness, strong tensile strength, excellent anti-aging performance, good corrosion resistance, smooth water flow and simple installation method.
Advantages of PVC drain pipe:
High surface hardness and tensile strength: The surface hardness and tensile strength of PVC drain pipe are excellent, ensuring the high safety factor of the pipe.
Excellent anti-aging performance: Under normal use, the service life of PVC drain pipe can reach more than 50 years.
Good corrosion resistance: It has good corrosion resistance to inorganic acids, alkalis and salts, and is suitable for industrial sewage discharge and transportation.
Smooth water flow: The friction coefficient of the pipe is small, the water flow is smooth, it is not easy to block, and the maintenance workload is reduced.
Self-extinguishing: The material has a high oxygen index and is self-extinguishing.
Small linear expansion coefficient: The linear expansion coefficient of the pipeline is small, the deformation affected by temperature is small, and the anti-freezing performance is excellent.
Simple installation method: The pipes and fittings of PVC drainage pipes can be connected by bonding or rubber rings. The construction method is simple, the operation is convenient, and the installation efficiency is high.
Good water tightness: Whether it is connected by bonding or rubber rings, PVC-U pipes have good water tightness.
Specifications and standards of PVC drainage pipes:
The specifications of PVC drainage pipes range from dn32 to dn315, and each specification corresponds to a fixed wall thickness. For example, the nominal wall thickness of dn75 is 2.3mm, dn110 is 3.2mm, and dn160 is 4.0mm.
The standard for PVC drainage pipes is GB/T5836.1-2018 “Hard Polyvinyl Chloride (PVC-U) Pipes for Building Drainage”.
What is the difference between them?
1. The main reason is that the PVC drain pipe has no pressure, and the PVC drain pipe is mainly used for indoor and outdoor drainage.
2. Water supply pipes are under pressure and can be used as farmland irrigation. PVC drain pipe pressure is generally small.
3. Drainage pipe is used for drainage. It is mainly used for drainage, rainwater, community drainage, etc. on real estate projects. There is no pressure and hygienic index requirement for the pipe itself. The quality of the pipe is mainly related to toughness and stretching.
4. The water supply pipe is used for water supply, and some is used for farmland irrigation. The biggest difference between the water supply pipe and the drainage pipe is that it needs to withstand the pressure. If it is a water supply project, it also needs to have health indicators, non-toxic and pollution-free detection indicators. At present, the market share of PVC water supply pipes is shrinking, and it is replaced by PE pipes with superior quality performance.
5. PVC threading pipe, for indoor use, thin wall, small pipe diameter, outdoor can have different caliber. Water supply pipe, wall thickness, high strength, pressure resistance, pipe diameter is generally medium. Drainage pipe, thin wall, medium strength, the key is generally larger.
Summary
PVC Plumbing Pipe and PVC Drainage Pipe should also be understood through this article. You don’t need to be curious about the difference between them. But you are curious about the difference between them because you need something for them, so you need to understand.
