1.What is welded pipe?
A: Welded pipe is a steel pipe made by bending and welding steel plates or strips. It is mainly used for transporting fluids and manufacturing structural components.
2.What is the difference between welded pipe and seamless pipe?
A: Welded pipe has a weld seam, resulting in lower production costs and higher efficiency, but its pressure-bearing capacity is generally lower than that of seamless pipe. Seamless pipe has no weld seam and is used in high-pressure, high-strength applications.
3.What is the difference between straight seam welded pipe and spiral welded pipe?
A: Straight seam welded pipe has a straight weld seam and is suitable for small-diameter pipelines; spiral welded pipe has a spiral weld seam and is suitable for large-diameter pipelines, offering higher strength.
4.What are the main uses of galvanized welded pipe?
A: Mainly used for transporting low-pressure fluids such as water, gas, and heating systems. The galvanized layer provides corrosion protection and extends service life.
5.What are the advantages of stainless steel welded pipe?
A: Corrosion resistant, high-temperature resistant, and aesthetically pleasing, it is suitable for industries such as food, chemical, and medical.
