The processing method of large-diameter steel pipe and expression method of the pipe diameter
Large-diameter steel pipe has won unanimous praise from consumers in use, and it is 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-di...Read more -
Internal and external anti-corrosion measures for steel pipelines
1. Common methods for external corrosion protection of steel pipes: Using the cathodic protection method alone is not economical due to the large power consumption. Therefore, the combined protection of the anti-corrosion layer and cathodic protection, the cathodic protection that will be concent...Read more -
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
