ASTM A252 S355jr Carbon Steel LSAW Pipe

Product Description

The ASTM A252 S355jr Carbon Steel LSAW Pipe is designed to be used as a structural pipe. This grade of carbon steel pipe is commonly used for the transmission of oil and gas, as well as the transportation of water and other liquids. The S355jr grade pipe has a higher yield strength compared to typical carbon steel pipes, making it ideal for applications that require a higher level of strength.

This carbon steel LSAW pipe is manufactured using the process of longitudinal submerged arc welding, which involves the formation of a welded seam along the length of the pipe. The LSAW process ensures a high level of accuracy and precision, resulting in a pipe that is dimensional uniformity and has a smooth surface finish.

The ASTM A252 specification for this pipe covers nominal wall thicknesses ranging from 0.85 inches to 24 inches, with outside diameters ranging from 16 inches to 60 inches. This wide range of sizes allows for flexibility in design and construction, making it suitable for a variety of applications.

One of the key features of the ASTM A252 S355jr Carbon Steel LSAW Pipe is its ability to withstand high external loads. This is achieved through the chemical composition of the steel, which includes a high concentration of manganese and silicon. These elements contribute to the overall strength and durability of the pipe, allowing it to

withstand heavy loads, pressure, and impact.

Another important characteristic of this pipe is its corrosion resistance. The carbon steel used in the manufacturing of this pipe is treated with a protective coating to prevent corrosion and extend its lifespan. This makes it an ideal choice for applications in environments with high levels of moisture, such as coastal areas or industries involving water transport.

The ASTM A252 S355jr Carbon Steel LSAW Pipe is widely used in various industries such as construction, structural support, piling, oil and gas transportation, and water supply systems. Its versatility and durability make it an excellent choice for these applications, ensuring long-lasting and reliable performance.

In addition to its structural and functional properties, this pipe also offers ease of installation. Its straight and uniform shape allows for easy alignment and joining, reducing the time and effort required for installation.

To ensure the highest quality standards, the ASTM A252 S355jr Carbon Steel LSAW Pipe undergoes rigorous testing and inspection procedures. These tests include visual inspection, flattening test, tensile test, impact test, and hydrostatic test. This ensures that the pipe meets the specified mechanical and chemical properties, providing peace of mind to users regarding its performance and reliability.

In conclusion, the ASTM A252 S355jr Carbon Steel LSAW Pipe provides a high level of strength, corrosion resistance, and ease of installation, making it a preferred choice for various applications. Its versatility, durability, and adherence to stringent quality standards make it a reliable and cost-effective solution for projects requiring a robust and long-lasting structural pipe.
