1. Manufacturing Process of Seamless PipesSeamless pipes are pipes without welds, usually formed through processes like extrusion, drawing, and expansion. The manufacturing process generally includes the following key steps:(1) Raw Material PreparationThe raw material is typically a steel billet or

In the manufacturing process of welded steel pipes, welding process is a crucial link. According to different welding methods, welding technology can be divided into several types. The three most common welding methods are high-frequency resistance welding (ERW), straight seam welding and spiral wel

The international trade situation and price fluctuations of welded pipes are influenced by various factors, including market demand, raw material costs, trade policies, and logistics costs. Below is a detailed analysis of the current state of international trade and price fluctuations for welded pip

1. Round Welded Pipes Definition:Round welded pipes are pipes made by rolling steel strips into a tubular shape and then welding them together. The internal and external diameters of round welded pipes can be adjusted according to requirements. Features:Even Load Distribution:The round cross-section

The growth in global energy demand and fuel trade is driving the development of the global pipeline transportation industry. Furthermore, urbanization is also playing a vital role in promoting the demand which supports infrastructure for water and sewerage lines. Most pipeline projects have a close relationship with hydrocarbon exploration activities. Large and medium welded pipes demand is mainly driven by major pipeline projects. Other factors which drive welded pipes demand include GDP growth, construction, automotive and chemical industries.

Welded pipes have low production costs, common raw materials, short production cycles, and can be manufactured into different lengths according to requirements, so they are used in large quantities.Welded steel pipes are widely used in many fields because of low cost and high efficiency.
