In the process of manufacturing lsaw steel pipe, lsaw steel pipe manufacturers need to have very good control of the pressing force. This is because during the welding process, when the temperature of...

We know that the ports of spiral steel pipes should be round, affecting the installation and use of spiral steel pipes, but due to external factors and other factors, the spiral steel pipes become an ...

1. The principle requirement of spiral steel pipe stacking is to ensure that the code is stable and safe, and that the materials of different varieties should be palletized separately to prevent entan...

SSAW steel pipe itself has no life limit, and the service life is mainly related to the operating environment and production process. Spiral steel pipe operating environment is relatively poor In orde...

The double-sided submerged arc welded spiral steel pipe produced by the ssaw steel pipe factory shall be subjected to mechanical performance test, flattening test and flare test before leaving the fac...

The ssaw steel pipe shall be the first to be in the performance test, the flattening test and flare test before leaving the factory, and shall meet the requirements specified in the standard. Physica...

The large-diameter ssaw steel pipe factory needs to test the product after the production is completed, especially its compressive capacity, because we usually use it in the ground when it is used, so...

Sub-temperature quenching, that is, incomplete quenching of thick-walled spiral steel pipe, or quenching in critical zone, heating quenching in two-phase zone, means that the steel piece is heated bet...

The raw material of ssaw steel pipe is a hot rolled plate, which is a strip or a coil. Hot-rolled steel sheets, that is, hot-rolled steel-rolled steel sheets or steel strips, commonly known as hot pl...

1. Welded steel pipe for low-pressure fluid transportation (GB/T3092-1993) is also called general welded pipe, commonly known as black pipe. It is a welded steel pipe used for conveying general lower ...
