PVC Drainage Pipes

PVC Drainage Pipes is a pipe made of sanitary polyvinyl chloride (PVC) resin as the main raw material. It is extruded by a plastic extruder and molded by an injection molding machine by adding an appropriate amount of stabilizer, lubricant, filler, color enhancer, etc., and then produced through cooling, curing, shaping, inspection, packaging, and other processes.

Advantages and characteristics

PVC Drainage Pipes, as a common drainage pipe material, have many advantages, making them an ideal choice for building water supply and drainage systems.

1. Excellent physical and chemical properties and chemical corrosion resistance: PVC drainage pipes have excellent physical and chemical properties and chemical corrosion resistance, and can resist the erosion of inorganic acids, alkalis, salts, and other substances. It is particularly suitable for industrial sewage discharge and transportation. ‌

2. High safety factor: PVC drainage pipes have excellent surface hardness and tensile strength, and the pipeline safety factor is extremely high, ensuring the safety of use. ‌

3. Long service life: The normal service life of PVC drainage pipes can reach more than 50 years. It has good anti-aging properties and can work stably for a long time. ‌

4. Lightweight and durable: PVC drainage pipes are light and durable, easy to install, and can speed up the progress of the project. ‌

5. Low cost: Compared with cast iron pipes of the same specifications, PVC drainage pipes can greatly reduce construction costs and save construction costs. ‌

6. Simple installation process: PVC drainage pipes are usually connected by sealing rubber rings, bonding, and flange connections. The construction is simple, the operation is convenient, and the installation efficiency is high.

Differences between HDPE and PVC Drainage Pipes

1. Material: PVC Drainage Pipes are made of polyvinyl chloride (PVC), while HDPE Drainage Pipe is made of high-density polyethylene (HDPE). Both materials are plastics, but they have different chemical structures and properties.

2. Elasticity: PVC pipes have lower elasticity, while HDPE pipes have better elasticity and can bend without breaking easily.

3. Function: PVC pipes are usually only allowed to be installed with cold water, while HDPE pipes can be used to install hot or cold water. In addition, HDPE pipes will not bend even in the sun due to their excellent heat resistance and corrosion resistance, making them suitable for various environmental conditions.

4. Price: The price of PVC pipes is relatively low, while the price of HDPE pipes is higher. This may be because HDPE pipes have better performance and longer service life. ‌

5. Application: PVC pipes are commonly used in water supply pipes, household pipes, etc., while HDPE pipes are suitable for water supply, gas pressure pipes, and drainage pipes due to their excellent pressure resistance and corrosion resistance. ‌

6. Performance: HDPE pipes have high strength and hardness due to their high crystallinity, smooth inner wall, small fluid resistance, small head loss, no scaling, reduced pipeline pressure loss and water delivery energy consumption, and have obvious economic advantages.
