Large-diameter steel pipes have won unanimous praise from consumers in use. They are widely used in mechanical parts, fluid transportation, construction sites, etc. Large-diameter steel pipes have undergone strict inspections during manufacturing, which has also improved their durability. Large-diam

1. Sandblasting method: Sandblasting uses a high-power motor to drive the sandblasting blades to rotate at high speed, so that steel sand, steel shot, wire segments, minerals, and other abrasives are sandblasted on the surface of the steel pipe under the effect of centrifugal force. It can not only

In the process of producing straight seam steel pipes, the temperature must be strictly controlled to ensure the reliability of welding. If the temperature is too low, the welding position may not reach the temperature required for welding. When most of the metal structures are still solid, it is di

First, acceptance of straight seam steel pipes:1. The inspection and acceptance of straight seam steel pipes shall be carried out by the supplier's technical supervision department.2. The supplier shall ensure that the delivered straight seam steel pipes meet the requirements of the corresponding pr

First, precautions for storing straight seam steel pipes: Most merchants do not use straight seam steel pipes quickly after purchasing them. So do we have anything to pay attention to in the storage of straight seam steel pipes? The staff of the straight seam steel pipe manufacturer reminded us that

First, domestic understanding of thick-walled steel pipes:Thick-walled steel pipes refer to steel pipes with a ratio of outer diameter to wall thickness of less than 20. They are mainly used as petroleum geological drilling pipes, cracking pipes for petrochemicals, boiler pipes, bearing pipes, and h

1. Suitable welding rods for A105 steel pipe fittings: structural steel welding rods, such as J426, J427 welding rods, etc.2. A105 is the American ASTM standard number, and A represents ordinary carbon structural steel. Standard name: Carbon steel forgings for pipeline components. Because this stand

First, steel elbowThe most commonly used is seamless elbow, which is divided into long-radius elbow and short-radius elbow. Among them, long radius elbow is the most commonly used elbow and its application is also very wide.Second, elbows are distinguished by specifications: Small and medium-sized a

About the production process of forged flanges:The forging process generally consists of the following steps, namely, selecting high-quality steel billets for blanking, heating, forming, and cooling after forging. The forging process methods include free forging, die forging, and membrane forging. D

After packaging and bundling, thin-walled stainless steel pipes should be stored in a dry and clean environment without corrosive gases to avoid being piled up with other items. Because the surface of stainless steel is relatively smooth and bright, and it is a metal product, it should be carefully
