What should be paid attention to when installing butt-welded steel elbows
Before the official installation of the butt-welded steel elbow, each steel elbow pipe joint must be measured and numbered, and the pipe joint group with the smallest difference in pipe diameter should be selected for docking. When splicing pipes on the ground, use 14×14cm sleepers under the pipe...Read more -
Detailed explanation of surface treatment and processing methods of thick-walled steel pipes
Thick-walled steel pipes have a wide variety of steel types and specifications, and their performance requirements are also various. All of these should be differentiated as user requirements or working conditions change. Generally, steel pipe products are classified according to cross-sectional ...Read more -
A brief analysis of temperature and lubrication problems in the production process of straight seam steel pipes
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, it may cause the welding position to fail to reach the temperature required for welding. When most of the metal structure is sti...Read more -
