Detailed description of quality problems that may be encountered in straight seam steel pipe products

The perforation temperature of the blank is different depending on the original material. Thermal expansion of steel pipes, but most in the 1200 °C or so, the carbon content and other alloying elements when the temperature is slightly lower.Carbon steel pipe, black steel pipe schedule 40, API 5l x56 erw welded steel pipe PSL1 PSL2

The second key to heating operation is to minimize the amount of scale. Especially in the hot kneading elbow, 16Mn straight seam steel pipe starts from the number of things and the surface quality of the kneading pipe material, and pleads more and more severely.

In the production process of the 16Mn straight seam steel pipe, since the primary processing is carried out in a hot state, the heating operation is a very important process for determining the product quality. building material/hollowsection tube/ERW Q235B ERWblack round  steel  welded  pipe 

For example, the furnaces used for heating are classified into two types, heating furnaces and reheating furnaces according to their effects.

Inappropriate heating will cause cracks, folding, and partial pain on the outer surface of the tube blank.Manufacture supply API5L SSAW spiral welded steelpipe with 3PE coating in Cangzhou .

There are many ways to heat the furnace, but the main application is the ring furnace. This furnace has a ring hearth, which can be slowly transformed, the billet is loaded along the diameter of the hearth from the inlet, reversed to the outlet where it can be heated and soaked to the regular temperature.
