Introduction to methods of rust removal from spiral steel pipes
1. Sandblasting and rust removal method: Sandblasting and rust removal uses a high-power motor to drive the sandblasting blades to rotate at high speed so that abrasives such as steel sand, steel shots, iron wire segments, and minerals can sandblast the surface of the steel pipe under the effect ...Read more -
Why stainless steel pipes need solution annealing treatment
Austenitic stainless steel is softened by solid solution treatment. Generally, the stainless steel pipe is heated to about 950 to 1150°C, and kept for some time, so that the carbides and various alloying elements are fully and evenly dissolved in the austenite, and then quickly quenched to cool. ...Read more -
