Seamless steel pipes are produced in various sizes to meet different industrial requirements. The size chart below includes the outer diameter (OD), wall thickness, and corresponding weight per unit length. Note that the actual availability may vary depending on the manufacturer.

LSAW (Longitudinal Submerged Arc Welding) steel pipes are manufactured using two primary welding methods: double-sided submerged arc welding (DSAW) and high-frequency welding (HFW). The choice of welding method significantly affects the possible diameter and wall thickness of the steel pipe produced.

In the heat treatment of seamless steel pipes, thermal stress and structural stress arise. These internal stresses can either superimpose or partially offset each other, resulting in a complex and variable stress pattern. Deformation during heat treatment is inevitable. Additionally, mechanical collisions during the heat treatment process can cause part deformation, but proper operational adjustments can help minimize and avoid this issue.

In the production of steel pipes, ensuring the quality and performance of the products is crucial. Here are the quality requirements and control methods for steel pipes in several key aspects.

Evaluating the quality of a spiral steel pipe factory involves a thorough assessment of various factors, ranging from the manufacturing process to the final product's quality. Here are key aspects to consider.

Spiral Submerged Arc-Welding (SSAW) steel pipes often face challenges related to rust due to their large individual sizes, which necessitate outdoor storage. Exposure to sun and rain makes rust prevention crucial for maintaining the quality and longevity of these pipes. Here’s a comprehensive guide to rust prevention for SSAW steel pipes.

ASTM A520 specifies the requirements for electric resistance welded (ERW) carbon steel mechanical tubing. These pipes are known for their versatility, durability, and high strength, making them suitable for various applications, including construction, automotive, and industrial uses.

Boiler tubes are essential components used to transport hot water or steam, and the choice of material significantly impacts their performance and service life. Here are some common materials used for boiler tubes.

High-frequency LSAW steel pipes offer significant advantages in terms of structural integrity, geometric precision, weld quality, and application flexibility. These benefits make them a preferred choice in various industrial applications, ensuring reliability and efficiency in pipeline construction and maintenance. This article will talk about advantages ofhigh frequencyLSAW steel pipe.

ASTM A192 seamless steel pipes are designed for high-pressure applications, primarily in boilers, superheaters, and heat exchangers. These pipes are known for their high tensile strength and durability.

The manufacturing loss rate of SSAW (Spiral Submerged Arc Welded) steel pipes refers to the proportion of raw materials lost during production. According to professional and technical personnel, the manufacturing loss rate typically ranges between 2% and 3%. Here's an overview of the manufacturing loss rate of SSAW steel pipe.

To ensure long-term performance and durability of the piping system, the installation of carbon seamless steel pipes should be carried out efficiently, safely, and reliably. This article will introduce the precautions for installation of carbon seamless steel pipe.
