1、Bonding method

Mainly used for hard pvc pipe, ABS pipe connection, the practice is in the socket and socket coated with binder, socket extrusion into the socket, to be binder curing that is. Most of the solvent bonding agent used for pvc in tetrahydrofuran or cyclohexanone solution, requires moderate viscosity, room temperature lower viscosity of 90Pa-S. Appearance of the flow state, no lumps, no delamination. PvVC content in the solution is not less than 10%.

2、Welding method

Mainly used for polyolefin pipes, such as LDPE, HDPE and PP pipe. Welding, the technical requirements of the operation is high, relatively less application.

3、Threaded connection

Threaded connection is safer and more reliable. However, due to open threads, pipe fittings must be thicker than the solvent method pipe fittings. Thread packing can be used white paint wire or raw material tape.

4, the connection of this connection has two methods: one is to use eccentric size head, the other is concentric size head. Reducer connection is mainly used for living health fittings (such as washbasin, bathtub) and drainage pipe fittings connection.
