Spiral steel pipe production process
(1) The raw materials are steel strip coil, welding wire, and flux. They must undergo strict physical and chemical inspections before being put into use. (2) For the head-to-tail butt joint of the steel strip, single-wire or double-wire submerged arc welding is used. After being rolled into a spi...Read more -
What is the difference between straight seam steel pipe and spiral steel pipes
First: welding process In terms of the welding process, the welding methods of spiral steel pipes and straight seam steel pipes are the same, but straight seam steel pipes will inevitably have many T-shaped welds, so the probability of welding defects is also greatly increased, and the welding re...Read more -
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 -
Basic knowledge of welded steel pipes
Welded steel pipe, also called welded pipe, is a steel pipe made of steel plates or steel strips that are welded after being curled and formed. The production process of welded steel pipes is simple, the production efficiency is high, there are many varieties and specifications, and the equipment...Read more -
The role of steel flange
Flange, also called flange or flange. It is the part that connects pipes. Connect to the pipe end. There are holes in the flange, and bolts can be inserted to tightly connect the two flanges. The flanges are sealed with gaskets. Flange pipe fittings refer to pipe fittings with flanges (flanges or...Read more
