The quality assessment process for ERW pipes involves a series of inspections and tests to ensure their reliability and structural integrity. This article will introduce these procedures in detail.

Seamless pipes are integral to various industries due to their superior strength, corrosion resistance, and ability to withstand high temperatures and pressures. Here, we explore their applications in different sectors.

This article will briefly introduce considerations when choosing SSAW steel pipes.

The standard fixed lengths for SSAW (Spiral Submerged Arc Welded) pipes are typically 6 meters, 12 meters, and 18 meters. These lengths are selected based on production requirements. Generally, shorter lengths are preferred for smaller pipes, while longer lengths are chosen for larger pipes.

Connecting SSAW (Spiral Submerged Arc Welded) steel pipes involves several techniques to ensure a secure, leak-proof joint. Here are the primary methods used for connecting SSAW pipes.

Welded steel pipes require anti-corrosion treatment during use. Choosing appropriate anti-corrosion methods can greatly extend the service life of steel pipes. Here are some anti-corrosion treatment methods for welded steel pipes.

To enhance the durability of SSAW (Spiral Submerged Arc Welding) steel pipes, exterior treatments are essential. Here are some effective methods.

During the forming process of spiral submerged arc welded (SSAW) pipes, various factors such as incorrect edge alignment, edge thickness variations, forming seam gap changes, and bridge oscillations can impact welding quality, leading to defects like inclusions and pores. These defects are more prevalent in thick-walled SSAW pipes compared to thin-walled ones, weakening the weld's effective cross-sectional area and reducing the welded joint's plasticity, toughness, and overall performance. This article outlines methods to prevent weld seam inclusions in SSAW pipes.

SSAW (Spiral Submerged Arc Welding) steel pipe is a type of welded steel pipe made from strip steel coils. Appearance inspection is a simple yet essential method for assessing SSAW pipe quality, primarily identifying surface defects and dimensional deviations.

According to the anti-corrosion coating standards for large-diameter submerged arc steel pipes, the methods for surface treatment of these pipes are continuously improved. This article discusses the various techniques for removing surface impurities from submerged arc welded steel pipes.

This article will briefly introduce the purpose of SSAW steel pipe preheating.

In water supply systems, SSAW steel pipes need effective anti-corrosion measures to ensure longevity and safety. Here are some commonly used methods.
