Spiral Submerged Arc Welding (SSAW) steel pipes are manufactured using strip coil as raw material. These pipes are formed by extruding the material at normal temperatures and welded with an automatic double-wire double-sided submerged arc welding process. Here, we explore the classifications and applications of SSAW steel pipes.

This article will briefly introduce processing methods commonly used for seamless steel pipes.

The A179 seamless steel pipe standard is a crucial specification in the steel industry, widely recognized for its importance in industrial production and construction. As a frequently used pipe material, seamless steel pipes have a broad range of applications. The A179 standard outlines specific production protocols and technical requirements, making it essential for professionals in the field to understand.

Carbon steel tubes are produced from steel ingots or solid round steel that are perforated into capillary tubes and then formed through hot rolling, cold rolling, or cold drawing. These tubes play a crucial role in the steel pipe industry in my country. The performance and longevity of carbon steel tubes depend significantly on the medium and working conditions they are exposed to. There is no definitive lifespan guarantee; even the best alloys can corrode within three months if not properly selected.

In the industrial sector, black carbon steel pipe is a widely used and crucial material. However, steel pipes are prone to corrosion, which can significantly shorten their lifespan. To protect black carbon steel pipes from corrosion, appropriate anti-corrosion measures are essential.

Seamless steel pipes are produced from tube blanks through processes such as high-temperature extrusion, cooling, annealing, and finishing. They are a key construction steel variety in China, used primarily for transporting fluids like water, oil, natural gas, and coal, as well as for building structures. Additionally, they are utilized in manufacturing carbon and alloy structural pipes for heavy industries including automotive, hydraulic equipment, and mining machinery.

Large Diameter LSAW pipes, known for their substantial wall thickness, excellent material quality, and process stability, are the preferred choice for major oil and gas pipeline projects both domestically and internationally. However, the weld joints, welds, and heat-affected zones (HAZ) in these pipes are susceptible to various imperfections such as undercuts, porosity, slag inclusion, lack of fusion, lack of penetration, burn-through, and welding cracks, which can lead to quality issues and potential accidents.

ASTM A53 Grade B seamless steel pipe is a crucial component extensively utilized in the petroleum, chemical, electric power, and machinery manufacturing industries. The following sections detail the characteristics and applications of this American standard seamless steel pipe.

This article will briefly introduce how to clean the surface of seamless pipes.

This article will briefly introduce the storage conditions of carbon steel pipes.

Here's an overview of characteristics and causes of 8 major defects of seamless steel pipes.

API 5L seamless line pipes are used extensively in the oil and gas industry for the transportation of gas, water, and oil. These pipes are designed to withstand high pressures and are essential for both onshore and offshore pipeline systems. Below are the key aspects of API 5L seamless line pipes.
