SSAW steel pipe is born on domestic 20th century until the late 90’s, Because of its safety and health, high strength, good corrosion resistance, durable, long life, maintenance-free, beautiful and so on, the current strong momentum of development of stainless steel round bar pipe, have been widely used in Building Water and Drinking Water pipes.
In most cases, straightness tolerance for the use of spiral steel pipe under large, but the manufacturing standards for spiral pipe straightness requests, if the predetermined value is exceeded, would constitute a reason to return, and therefore, spiral pipe plant should still be noted.
Roundness tolerance will affect the use of spiral steel pipe, mainly in the group of the wrong side of the welding head. Roundness tolerance has led to the wrong side of the welded joint will not only reduce the pressure capability, but also stress concentration. When the site Group, roundness some pipe can be corrected. Outside diameter deviation and the impact on the spiral steel pipe used roundness tolerance fairly.
The application characteristics of high bearing capacity steel pipe pile, the construction process is simple, fast construction, material for multiple use of working capital, a simple connection between the pile and the pile, good stability, low construction costs.
