Methods and annealing steps for preheating deformation of straight seam steel pipes
Methods for preheating deformation of straight seam steel pipes: 1. Reasonable material selection. For precision complex molds, micro-deformation mold steel with good quality should be selected. Mold steel with serious carbide segregation should be reasonably cast and subjected to quenching and t...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 -
Why are large-diameter steel pipes mostly welded with steel
1. The uses of large-diameter stainless steel pipes can be divided into oil well pipes (casing, oil pipes, drill pipes, etc.), pipeline pipes, boiler pipes, mechanical structural pipes, hydraulic support pipes, gas cylinder pipes, geological pipes, and chemical pipes (high-pressure fertilizers). ...Read more -

Spiral welded pipe production process
Spiral welded pipe is also a type of welded pipe equipment. Its strength is generally higher than that of straight seam welded pipe. It can use narrower billets to produce welded pipes with larger diameters. It can also use billets of the same width to produce welded pipes with different diameter...Read more
