In the sales and application of plastic pipe systems, about 15%~20% of the sales are pipe fittings, and pipe fittings are mainly divided into hot-melt pipe fittings and electric melt pipe fittings. Due to the price, hot-melt pipe fittings are used more in engineering applications than electric melt pipe fittings, but electric melt pipe fittings play an important and irreplaceable role in engineering and maintenance. Especially in construction, electric melt pipe fittings are almost free from the influence of external environment and human factors, Therefore, it is more reliable and popular with users. At the same time, as the production technology of electric melting pipe fittings is complex, the cost is high, and the sales price is also high, the profit margin of electric melting pipe fittings manufacturers is also high, which has become a hot investment.
Generally speaking, electric melting pipe fittings are divided into PE electric melting pipe fittings and PE-RT electric melting pipe fittings.
The base of PE electric melting pipe fittings is polyethylene PE material, which is a thermoplastic resin polymerized from ethylene. It is odorless, non-toxic, and feels like wax. It has excellent low temperature resistance, good chemical stability, and can withstand the corrosion of most acids and alkalis.
The matrix of PE-RT electric melting pipe fittings is heat resistant polyethylene PE-RT material, which is polymerized by medium density polyethylene (MDPE) and octene, and is resistant to high temperature, freezing and impact.
What are their respective uses?
1. PE electric melting pipe fittings are mainly used for building water transmission and drinking water pipeline systems, generally lower than 40 ℃.
2. PE-RT electric melting pipe fittings are mainly used in the following three aspects:
a. Building cold and hot water pipeline system, including civil and industrial building cold and hot water, drinking water.
b. Central air conditioning water supply and return system
c. Heating system
