Welding is a critical step in the production of Electric Resistance Welded (ERW) carbon steel pipes, directly affecting their strength, integrity, and durability. However, due to the complexity of the welding process and material characteristics, various defects can occur if proper procedures are not followed. This article outlines the most common welding defects found in carbon steel ERW pipes, their causes, characteristics, and potential impacts on performance.
May 22, 2025 read moreCarbon steel Electric Resistance Welded (ERW) pipes are widely used in various industries due to their cost-effectiveness and manufacturing efficiency. Produced through a high-speed continuous process, ERW pipes are known for their versatility in applications ranging from structural components to oil and gas pipelines. However, like any material, they come with both advantages and limitations. Understanding these pros and cons is essential for making informed decisions in project design, material selection, and engineering application.

May 15, 2025 read moreRoll forming is a widely used method in Electric Resistance Welded (ERW) pipe production. It involves using metal sheets or coils as raw materials, which are gradually bent and shaped through a series of roll stands equipped with specially designed forming rollers. Each stand typically includes two or more rollers, and the material undergoes continuous deformation until it achieves a uniform cross-section.
May 14, 2025 read moreWhen selecting steel pipes, a common question is whether to use seamless or welded pipes. Making the right choice is essential to ensure the pipeline's stability, durability, and cost-effectiveness. A key factor in this decision is the nominal size of the pipe.

While both are used in construction and industrial applications, they differ significantly in terms of manufacturing process, material requirements, and typical use cases. Below is a detailed comparison.
May 08, 2025 read moreAPI 5L X65 specification pipe is also called ISO 3183 L450 pipe, which has a higher grade. API 5L X65 pipe is mainly used for the transportation of natural gas and oil. API 5L X65 pipe has a higher yield strength, and its minimum value is 450 MPa.
May 06, 2025 read moreAPI 5L X60 (L415) is a line pipe with a minimum yield strength of 60,200 MPa (415 MPa) used in pipeline transportation systems in the oil and gas industry.
May 05, 2025 read moreWelded carbon steel pipes are fundamental to a wide range of industries, playing vital roles in structural frameworks, mechanical systems, and general fabrication processes. To ensure uniformity, reliability, and safety in their use, the American Society for Testing and Materials (ASTM) has established comprehensive standards covering dimensions, materials, and tolerances. This guide outlines the importance of ASTM sizes for welded carbon steel pipes, including key specifications and factors to consider when selecting appropriate pipe dimensions.
Apr 30, 2025 read moreX52 is an intermediate grade in API 5L, combining high strength with economy. Widely used in oil and gas transportation, construction projects, submarine pipelines, etc. ISO 3183 is the International Standardization Organization standard for the Petroleum and natural gas industries —Steel pipe for pipeline transportation systems. This International Standard specifies requirements for the manufacture of two product specification levels (PSL 1 and PSL 2) of seamless and welded steel pipes for use in pipeline transportation systems in the petroleum and natural gas industries.
