Solutions to rust spots on stainless steel elbows
There will be rust spots on the stainless steel pipe elbow, which means that the elbow is not made of pure stainless steel, but an electroplated stainless steel elbow. The rust spots can be polished with ultra-fine sandpaper and then sprayed with colorless varnish for anti-rust treatment. It is r...Read more -
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 -

According to different production methods, it can be divided into hot-rolled tubes, cold-rolled tubes, cold-drawn tubes, extruded tubes, etc. 1.1. Hot-rolled seamless steel pipes are generally produced on automatic pipe rolling units. After checking and removing surface defects, the solid tube bl...Read more -
What should be paid attention to when installing butt-welded steel elbows
Before the official installation of the butt-welded steel elbow, each steel elbow pipe joint must be measured and numbered, and the pipe joint group with the smallest difference in pipe diameter should be selected for docking. When splicing pipes on the ground, use 14×14cm sleepers under the pipe...Read more -
About the production process and inspection standards of thick-walled straight seam steel pipes
Thick-walled straight seam steel pipe is a steel pipe made by rolling the long steel strip of the specification into a round pipe through a high-frequency welding unit and welding the straight seam. The shape of the steel pipe can be round, square or irregular, depending on the sizing and rolling...Read more -
Description of the length and mechanical properties of large-diameter steel pipes
The main processing methods of large-diameter steel pipes are: Forging steel: a pressure processing method that uses the reciprocating impact force of a forging hammer or the pressure of a press to change the blank into the shape and size we need. Extrusion: It is a processing method for steel to...Read more
