PVC (polyvinyl chloride) and PE (polyethylene) pipes are both commonly used for plumbing and water supply applications, but they have some key differences in terms of their properties and applications. Material Composition: PVC is made from a synthetic plastic polymer, while PE is made from a thermoplastic polymer.

2023年10月7日 · Both PE and PVC pipes are commonly used to transport large volumes of liquid (water, fertilizer, hazardous chemicals) at a high velocity. Plastic pipe are able to maintain this velocity with less drag and turbulence than traditional concrete or metal pipes providing greater resistance to scaling and buildup. PE and PVC pipes are also better at ...

2024年10月25日 · Polyethylene pipe vs pvc, commonly referred to as PE pipes, are made from polyethylene, a thermoplastic polymer known for its durability and flexibility. PE pipes are typically available in three main forms: High Density Polyethylene pipe (HDPE) , Medium-Density Polyethylene (MDPE), and Low-Density Polyethylene (LDPE).

pe-rt管具有符合产品标准的蠕变破坏曲线，是聚乙烯中现阶段唯一不需交联就可用于热水管的一个品种。 另外PE-RT具有优越的耐低温性能，因此在冬季低温情况下也可以施工，弯曲管道时无需预热，可以解决我国北方地区冬季气温低，无法施工而造成的经济损失。

PE: polyethylene pipes are made of polyethylene polymer. They are flexible, soft and impact resistant. These characteristics make PE pipes withstand well and perform well in tolerating changes in volume at different temperatures. PVC: PVC pipes are well resistant to acids, alkalis, chemicals and external factors.

2022年3月4日 · The standard of PE water supply pipe is GB / t13663-2000 and the standard of PVC water supply pipe is GB / t10002 1-2006. The requirements for wall thickness and performance indexes of the two are different in the standard.

pvc 和 pe 管具有不同的特性和强度，使其适用于各种管道和供水应用。 在 PVC 和 PE 管道之间进行选择时，必须考虑具体应用、环境条件、安装要求、耐化学性、寿命和环境影响。

2023年6月2日 · When it comes to PVC and PE, both materials offer excellent electrical insulation. PVC is a hard plastic that has great dielectric strength, making it an ideal choice for electrical applications. On the other hand, PE is a softer material with slightly lower dielectric strength than PVC, but its flexibility makes it more suitable for tight ...

2025年3月20日 · Polyvinyl chloride (PVC) and polyethylene (PE) pipes are two dominant materials in modern piping systems, widely used in water supply, drainage, gas transportation, and industrial applications. While both are thermoplastic polymers, their distinct chemical compositions, physical properties, and application scenarios necessitate careful ...

PE pipe contains only two elements of hydrocarbon and has good hygienic performance. PVC contains heavy metals such as lead, and the hygienic performance is slightly worse. But, the hygienic performance of PVC pipe with calcium and zinc stabilizer is also combined with national sanitary standard GB/T17219.
