According to the purpose and pipe material, the commonly used connection methods of construction pipelines are threaded connection, flange connection, welding, groove connection (clamp connection), ferrule connection, compression connection, hot melt connection, socket connection, etc.
Threaded Connection
The threaded connection is connected by threaded pipe fittings. The galvanized steel pipe with a pipe diameter less than or equal to 100mm is suitable for threaded connection, and it is mostly used for surface-mounted pipes. Steel-plastic composite pipes are generally also threaded. The galvanized steel pipe shall be connected by threads, and the surface of the galvanized layer and the exposed thread parts damaged during the threading shall be treated with anticorrosion; flanges or ferrule-type special pipe fittings shall be used for connection, and the welding place between the galvanized steel pipe and the flange shall be two Secondary galvanizing.
Flange Connection
Pipes with larger diameters are connected by flanges. Flange connections are generally used in main roads to connect valves, check valves, water meters, water pumps, etc., as well as on pipe sections that require frequent disassembly and maintenance. If the galvanized pipe is connected by welding or flange, the welding place should be galvanized twice or anti-corrosion
