Brief introduction to the manufacturing skills of spiral steel pipe manufacturers
There are many kinds of metallic pipes and distinct uses, so their technical necessities are distinct and manufacturing strategies are distinct.
According to the molding method, the metallic pipe may be divided into categories: thermoformed metallic pipe and bloodless shaped metallic pipe.
Among them, thermoformed metallic pipes may be divided into warm rolled metallic pipes and warm completed metallic pipes. Hot-rolled metallic pipe is a warm-milk seamless metallic pipe, which accommodates a warm extruded pipe that is rolled and extruded at a excessive temperature, and a warm-increased tube that is re-extruded with the aid of using a warm-rolled thick-walled seamless metallic pipe and thermally increased. The unevenness of the velocity and temperature of the tube at some stage in enlargement can bring about an choppy boom withinside the thickness of the tube wall. The warm-completed shaped metallic pipe is acquired with the aid of using heat-treating a large-diameter instantly welded pipe welded with the aid of using a curved shape, that could get rid of residual strain and enhance plasticity.
The bloodless-shaped tube is shaped with the aid of using bending a metallic sheet at a ordinary temperature after which welding it thru a weld.
For the development of metallic pipe structure, the spherical pipe and the square pipe may be manufactured from warm milk, warm increased seamless metallic pipe, or instantly welded pipe that is shaped with the aid of using roll forming, bloodless forming and warm forming. The square pipe also can be welded with the aid of using metallic plate. Welding may be performed with the aid of using excessive frequency welding, automated welding or semi-automated welding and guide welding. The welding cloth ought to be matched with the bottom metal.
