PP/PE coiled core tubing

PVC pipes include medium density PVB pipes and high density PVB pipes. Depending on the thickness, they are divided into SDR11 and SDR17.6 series. The former is suitable for conveying artificial gas, natural gas and liquefied gas, while the latter is mainly for conveying natural gas. Compared with steel pipes, the construction process is simple and flexible. Moreover, there is no need for anti-corrosion treatment, thus saving many processes. The disadvantage is that the equipment is not as good as steel pipe. Special attention should be paid to the heating safety distance, not exposed to sunlight, and sensitive to chemicals to prevent damage caused by sewage pipe leakage. Polyethylene vacuum sheathing production line side slope briefly describes the classification of polyethylene pipes.

According to the way the parts are made: injection parts and welded parts.

According to the construction method and application: electrothermal fusion parts, thermal fusion parts, bearing inserts, plastic steel joints.

According to engineering custom: casing, elbow, tee, saddle, reducer, end plug, flange, steel-plastic conversion.

Polyethylene pipes are mainly classified according to pressure ratings of 0.6 MPa, 0.8 MPa, 1.0 MPa, 1.25 MPa and 1.6 MPa. Refers to the unit of pressure, e.g. 0.6 MPa indicates a pressure of 6 kg.
