Product Details
Round Welded Steel Spiral Pipe is a kind of spiral welded steel tube with strip steel coil as raw material, which is often shaped by warm extrusion and welded by automatic double wire and double submerged arc welding process.
Round Welded Steel Spiral Pipe production process is simple, high production efficiency, low cost, rapid development.

Influence Round Welded Steel Spiral Pipe on flow characteristics of conveying medium The pressure drop in the conveying pipeline is directly proportional to the length of the pipe, the coefficient of fluid viscosity, the coefficient of fluid velocity, and the coefficient of fluid resistance, and inversely proportional to the diameter of the pipe. The Round Welded Steel Spiral Pipe fluid resistance coefficient is related to both the Reynolds number and the roughness of the inner surface of the pipe. It Round Welded Steel Spiral Pipe has been found that the roughness of the inner surface of the pipe has ten times more effect than the area of local uplift, such as spiral or longitudinal welds, or even inner ring welds.
