What are the cutting methods for thick-walled spiral steel pipes
1. Mechanical cutting of thick-walled spiral steel pipes employs two methods: external and internal installation. Mechanical cutting uses a lathe tool to cut and bevel the pipe ends. It has a large single-machine span, can process large thicknesses, produces little waste, is pollution-free, and d...Read more -
What are the daily maintenance and production procedures for thick-walled straight seam steel pipes in industrial projects
The advantages of thick-walled straight seam steel pipes lie in the fact that the online heat treatment process of the weld seam eliminates welding stress, refines the microstructure grains in the heat-affected zone, and improves physical and mechanical properties. Developed Western countries emp...Read more -
Why do precision steel pipes need pickling
1. Pickling removes oxide scale (iron oxide scale) from precision steel pipes. During hot rolling or annealing, a hard oxide scale (FeO, Fe₂O₃, Fe₃O₄) forms on the surface of precision steel pipes. This scale is very difficult to remove mechanically and affects the surface quality of the precisio...Read more -
Troubleshooting and Production Technology of Straight Seam Steel Pipes in Industrial Projects
Straight seam steel pipes are steel pipes where the weld seam is parallel to the longitudinal direction of the pipe. They are typically classified into metric welded steel pipes, welded thin-walled pipes, transformer cooling oil pipes, etc. Straight seam welded steel pipes have a simple productio...Read more -

Hot-dip galvanized steel pipes: This involves reacting molten metal with the iron substrate to cr...Read more -
Why are 316L stainless steel pipe fittings commonly used in industrial projects
The common use of 316L stainless steel pipe fittings in industrial projects as project accessories is not solely due to their superior corrosion resistance. The reasons are actually as follows: 1. 316 stainless steel is a molybdenum-containing stainless steel. Due to the molybdenum content, its o...Read more -
Horizontal Fixed Welding and Usage Precautions for Thick-Walled Stainless Steel Pipes
First, Horizontal Fixed Welding of Thick-Walled Stainless Steel Pipes. Stainless steel pipes are hollow, long strips of steel, widely used as pipelines for transporting fluids such as oil, natural gas, water, coal gas, and steam. Stainless steel pipes are lighter in weight while maintaining the s...Read more -
Regarding the Wall Thickness Accuracy and Straightening Methods of Straight Seam Steel Pipes in Industrial Projects
Controlling the wall thickness of straight seam steel pipes is a challenge in steel pipe production. Currently, straight seam steel pipe manufacturers generally use the following methods to ensure wall thickness accuracy during production: 1. Billet Heating: Heating should be uniform, avoiding ra...Read more -
Causes and Adjustments for Uneven Steel Pipe Wall Thickness Commonly Found in Industrial Projects
1. Spiral Uneven Wall Thickness: Causes include uneven wall thickness due to misalignment of the piercing mill rolling centerline, unequal inclination angles of the two rolls, or insufficient pre-pressurization of the mandrel. This unevenness typically presents a spiral distribution along the ent...Read more -
