Definition, function, and standard code of high-frequency welded steel pipe
1. Welded steel pipes for low-pressure fluid transportation (GB/T3092-1993) are also called generally welded pipes, commonly known as clarinet pipes. It is a welded steel pipe used for conveying water, gas, air, oil, heating steam, and other general lower-pressure fluids and other purposes. The w...Read more -
Stages and standard parameters of mechanical expansion process for large diameter steel pipes
The stages of the mechanical expansion process of large-diameter steel pipes: The steel plate is first pressed into a U shape in the forming die, and then pressed into an O shape, and then internal and external submerged arc welding is performed. After welding, the diameter is usually enlarged at...Read more -
Advantages of straight seam steel pipes and steel structure applications
Straight seam steel pipe is a welding process of steel pipe opposite to spiral steel pipe. The welding process of this kind of steel pipe is relatively simple, and the cost of welding is relatively low, and it can achieve high efficiency during production, so it is relatively common in the market...Read more -
Some installation points about stainless steel pipe fittings
The installation method of stainless steel pipe fittings is the same as that of ordinary carbon steel pipe fittings, but there are some special requirements in some processes. as follows: 1. The material of stainless steel pipe fittings should not be in direct contact with other metals, and shoul...Read more -
What are the characteristics of large diameter steel pipes
1. Impact toughness of large-diameter steel pipe: The load acting on the machine part at a high speed is called impact load, and the ability of the metal to resist damage under the action of impact load is called impact toughness. 2. Strength of large-diameter steel pipe: Strength refers to the p...Read more -
