I. Introduction
With the continuous growth of global energy demand and the enhancement of environmental protection awareness, the development and utilization of clean energy has become a common focus of all countries. The transportation and distribution of clean energy put forward higher requirements for pipeline systems. Spiral welded steel pipe (Spiral Submerged Arc Welding, SSAW) plays an important role in the transportation of clean energy with its unique advantages. This article will discuss the manufacturing process, characteristics and specific application of SSAW steel pipe in the transportation of clean energy in the environmental protection industry.
II. Manufacturing process of SSAW steel pipe
The manufacturing process of SSAW steel pipe mainly includes the following steps:
Material preparation:
High-quality steel plates or steel strips are selected as raw materials. These materials usually have good mechanical properties and corrosion resistance to ensure the service life and reliability of steel pipes.
Forming:
The steel plate or steel strip is rolled into a tube according to a certain spiral angle. The forming process requires high precision to ensure the roundness and straightness of the steel pipe.
Welding:
Double-sided submerged arc welding technology is used for welding to ensure the strength and quality of the weld. Double-sided welding not only improves welding efficiency, but also reduces weld defects and ensures the overall performance of the steel pipe.
Inspection:
Strict non-destructive testing is performed on the formed steel pipe, such as ultrasonic testing and X-ray testing, to ensure that the weld and the parent material are free of defects.
