Connection mode of straight seam steel pipe and other pipes
The common ways to connect straight-seam steel pipes with pipes of different materials and specifications are welding, flange connection and threaded connection.
Welding connection is suitable for occasions that require high strength and tightness, such as high-pressure pipelines. Its advantages are firm connection and good sealing, but it needs professional equipment and personnel, and it is easy to produce deformation and residual stress, and it is not easy to disassemble and maintain.
Flange connection is suitable for all kinds of pipes, especially in the case of large diameter and high pressure. The connection and disassembly are convenient, and the installation and maintenance are convenient, but the cost is high, the weight is heavy, and the uneven fastening of bolts or the damage of gaskets may cause leakage.
Threaded connection is often used in pipes with small diameter and low pressure. It is simple to manufacture and use, and has good versatility, but its sealing performance is relatively poor, and it may loosen when it bears pressure or vibration. When selecting the connection mode, factors such as pipeline use, pressure and material should be considered to ensure the tightness, strength and reliability of the connection. Different methods have different effects on the overall performance of the pipeline system and need comprehensive consideration.
