There are many ways to link steel pipes (such as seamless pipes and welded steel tubes), and the commonly used ones are:Compression type, union type, compression type, pusher type, taper thread type, socket welding type, union type flange connection, welding type and derivative series connection methods combining welding and traditional connection.
Different connection methods have different fields of application due to their different production principles, but generally speaking, they all have one thing in common, that is, easy installation, firmness and reliability. The appropriate connection method can be selected in combination with the actual situation, because the connection method also has certain requirements for the diameter of the steel pipe.
1. Compression type: Insert the pipe into the nozzle of the pipe fitting, fasten it with a nut, and use the screw force to compress the sleeve at the nozzle through the sealing ring, which acts as a seal and completes the connection of the pipe.
2. Welding type: The end of the pipe is processed with a bevel, and the pipe is welded circularly by manual or automatic welding.
3. Flange type: The flange and the pipe are welded by circular argon arc welding, and fastened with quick clamps or bolts, so that the gasket between the flanges acts as a seal to complete the pipe connection.
4. Compression type: Insert the pipe into the pipe fitting and use a special installation tool to press the pipe wall into a hexagonal shape, and the internal sealing ring is also deformed into a hexagonal shape
5. Taper thread type: the outer thread and the pipe are welded by circular argon arc welding, and the inner thread pipe fittings are sealed by the taper thread connection to complete the pipe connection.
