Product name: Anti-corrosion steel elbowSize: customized sizeStandard: ASTM A234 WPB WPC Project Location: BrazilThe order is from an old client, who needs to applicate for the energy transportation project. When the product arrived at the energy transportation project location, it was quickly used.

The main technical characteristics of spiral steel pipe:During the forming process of the spiral steel pipe, the steel plate is uniformly deformed, the residual stress is small, and there is no scratch on the surface. The processed spiral steel pipe has greater flexibility in the range of diameter a

Submerged arc steel pipe welding control measures:Submerged arc steel pipe has become the steel pipe for large-scale oil and gas transmission projects at home and abroad because of its large wall thickness, good material, and stable processing technology. In large-diameter submerged arc steel pipe w

What they have in common is that they all belong to inner and outer plastic-coated steel pipes, but fire-fighting plastic-coated steel pipes are only one category of inner and outer plastic-coated steel pipes.We are already familiar with the plastic-coated composite steel pipe inside and outside. Wi

Introduction of anti-corrosion on the inner wall of large-diameter steel pipes:1. Before processing all steel pipes, the steel plate on the inner wall side of the large-diameter steel pipe shall be derusted until the metal is exposed to metallic luster (whitening). It should meet the sa2.5 standard

Product: Galvanized Steel PipeApplication: Industrial Steel Structure projectStandard: BS1139Product arrived Location: MalaysiaSize: 50x1.5x12000mmThe order is from a new client, who needs to applicate for a new industrial steel structure project. When the product arrived at the steel structure loca

Matters needing attention in the use of thick-walled steel pipes:How much wall thickness can be called thick-walled steel pipe? This is a bit doubtful. It depends on the ratio of the outer diameter of the steel pipe to the wall thickness of the steel pipe. For example, a steel pipe with a diameter o

The length of steel pipes used for pipelines, but for the convenience of users, when the steel pipes sold at any time are reserved for production, the Q235A spiral steel pipes are produced within the specified length of the steel pipes, but when the actual order is made, the steel pipes of standard

Improper heat treatment of seamless steel pipes is likely to cause a series of production problems, resulting in greatly reduced product quality and turning into waste products. Avoiding mistakes that are easy to make during heat treatment is saving money. What problems should we pay attention to an

To solve the problem of excessive misalignment in the alignment of spiral steel pipe nozzles, the following preventive measures should be taken in quality management control:1. Try to use the internal alignment device.2. Do a good job in engineering measurement and trimming when assembling.3. When t
