초록
Plastic pipes are usually made by polybutylene (PB), poly(vinyl chloride) (PVC), ethylenepropylene rubber (EPR), linear low density polyethylene (LLDPE), polypropylene (PP), crosslinkedpolyethylene (PE-X), etc. Especially PE-X pipes have toughness to withstand high temperature andhigh pressure, and have long-term usable features. For example, the maximum service temperatureand pressure of PB are known to be 90°C and 0.4 MPa, respectively, whereas PE-X pipes withstand110°C, and the maximum service temperature and pressure are 95°C and 0.65 MPa. PE-X has verygood toughness, environmental crack resistance, slow crack grip resistance, and also has resistanceto electrolysis, corrosion and chemicals. Its advantages over competing materials such as steel andcopper pipes include speed and ease of installation, low cost of materials, durability and flexibility. In general, PE pipes are divided into non-crosslinked and crosslinked ones. PE-X pipes are used inlarge quantities in plumbing pipes that circulate hot water because of their high heat resistance, andthe market is growing rapidly. The technology and status of PE-X pipe processing are discussed inthis article.
