The allowable wall thickness error for Spiral Submerged Arc Welded (SSAW) steel pipes is specified to ensure the pipes meet structural and safety requirements while maintaining uniform quality. The tolerance levels for wall thickness can vary based on standards and specifications, but generally adhere to the following principles.

The pressure grade of welded steel pipes is a crucial factor in determining their suitability for various applications. This grade is influenced by several factors, including wall thickness, outer diameter, working pressure, and the type of medium being transported. Higher pressure grades require more stringent conditions and technical specifications to ensure safe and reliable operation. According to national standards, welded steel pipes are categorized into different pressure levels as follows.

In the production of electric resistance welded (ERW) steel pipes, the internal weld surface is typically treated using one of two methods: incomplete scraping (retaining some weld reinforcement) or complete scraping (which forms a groove on the inner surface). The effectiveness of these methods can significantly impact the overall performance of the steel pipe.

Welded pipes, also known as welded steel pipes, are manufactured by rolling steel plates or strips into a tubular shape and then welding the edges together. This process typically involves flattening, crimping, welding, and leveling the material. There are two primary production methods for welded pipes: cold rolling and hot rolling.

SSAW steel pipes are crucial materials used in industries such as petroleum, natural gas, and water treatment. High-quality spiral welded pipe manufacturers emphasize the careful selection of production equipment and the optimization of processes to ensure consistent product quality and enhance production efficiency.

Ovality is a significant measure of the dimensional accuracy and production quality of steel pipes. It can be calculated using the diameter method, ellipticity calculation, or roundness deviation calculation. This article will introduce theovality standard of carbon steel tubes.

Hoisting seamless steel pipes is a critical engineering task that requires careful attention to several key factors. Here’s what you need to keep in mind.

With the growth of the construction, engineering, and manufacturing industries, spiral welded steel pipes have become essential components in pipelines, bridges, and building structures. Accurate measurement of their length is critical during production, installation, and maintenance. Here are three commonly used methods for measuring the length of spiral welded steel pipes.

ERW steel pipes are widely used in industries like construction, transportation, and utilities due to their high efficiency and cost-effectiveness. The weld seam is a critical area in ERW pipes, and ensuring its quality is essential for the pipe's overall performance. The online heat treatment process of the weld seam is a crucial step to enhance its mechanical properties and ensure the integrity of the pipe.

The carbon content in steel pipes refers to the proportion of carbon present, typically expressed as a percentage by mass. This article will briefly introduce carbon content range in carbon steel pipes.

Seamless (SMLS) steel pipes are widely used in industrial applications, and their straightness is a crucial quality indicator. Adequate straightness is necessary to ensure the proper functioning of the pipes; deviations can adversely affect their performance. To maintain quality, national standards have been established to regulate the straightness of seamless steel pipes. This article provides an overview of these standards.

In the production of carbon steel seamless pipes, cold treatment processes are often employed to enhance the material's strength and hardness. Below is an overview of the typical cold treatment methods used for seamless steel pipes.
