Ensuring high-quality welds in spiral steel pipes involves meticulous attention to several critical factors. Here are some comprehensive guidelines to help achieve superior welds.

Heat treatment of Longitudinal Submerged Arc Welded (LSAW) steel pipes after welding is a modern technique used to eliminate residual stress. This process involves preheating the material to the heat treatment temperature before welding, maintaining this temperature during the welding process, and then allowing the pipe to cool slowly using thermal insulation materials. This method effectively reduces welding residual stress and improves the metal's resistance to stress corrosion.

Welded steel pipes can exhibit a range of surface defects that affect their quality and performance. Understanding these defects is crucial for quality control and ensuring the integrity of the pipes in various applications. Here are some common surface defects found in welded steel pipes.

SSAW steel pipes offer significant advantages such as high structural integrity, versatile dimensions, cost efficiency, and superior weld quality, making them suitable for a broad spectrum of applications. Their versatility and durability ensure their continued use in industries ranging from oil and gas transportation to construction and industrial projects. This article will introduce the advantages and application of SSAW steel pipe.

Seamless steel pipes are made through a process that does not involve welding or joints, resulting in a continuous, uniform structure throughout the length of the pipe. Here’s an overview of the manufacturing process.

Schedule 40 Electric Resistance Welded (ERW) pipes are widely used in various applications, including water supply, drainage, and gas distribution. This comprehensive guide explores the characteristics, uses, manufacturing process, and advantages of Schedule 40 ERW pipes in detail.

Carbon steel welded pipe, commonly referred to as black steel pipe, is a ubiquitous material used across various industries due to its durability, strength, and affordability. Here we are going to talk about the life expectancy of carbon steel welded pipe.
