API 5L GR B Pipe Manufacturer

Kalpataru Piping Solution is known as a top manufacturer and supplier of API 5L Grade B seamless pipes. These pipes are produced from high-quality carbon steel, with a significant addition of manganese, which enhances their mechanical properties. The manganese acts as a microalloying agent, improving the pipes’ strength, hardness, and durability.API 5L Grade B pipes are commonly subjected to carburizing or nitriding processes to enhance their surface hardness. Nitriding involves heat treatment combined with nitrogen diffusion, resulting in increased hardness and wear resistance.

Our API 5L Grade B seamless pipes are available in sizes ranging from 1/2″ NB to 60″ NB, These pipes are widely used in oil and gas refineries, petrochemical plants, and other sectors requiring robust and reliable piping solutions. The API 5L Grade B pipes are manufactured under two product specification levels, PSL1 and PSL2, each catering to specific requirements. The PSL1 grade provides standard quality for line pipes, while PSL2 pipes come with additional requirements for chemical composition, mechanical properties, notch toughness, and non-destructive testing. This ensures that PSL2 pipes offer superior performance and durability, making them ideal for demanding applications.

API 5L Grade B pipes are resistant to cracking caused by sulfur, making them ideal for harsh environments. They have a minimum yield strength of 245 MPa (about 35,500 psi), making them affordable and dependable for many industrial uses.For more information or to discuss your specific requirements, please contact us. We are committed to delivering the best piping solutions to meet your needs.

What Is API 5L Grade B Pipe?

API 5L Grade B pipes, made primarily from carbon steel with trace elements, are known for their strength, dimensions, and resistance to cracking. Ideal for long pipelines, especially in environments with hydrogen sulfide, they prevent brittleness and have a long lifespan, making them cost-effective. Commonly used in the petroleum, petrochemical, and natural gas industries, these pipes are reliable for transporting fluids and gasses due to their sturdy design and ability to withstand pressure.

Types of API 5L Gr B Pipe

  1. PSL1 & PSL2 Types
    • PSL1: This specification is commonly used and is equivalent to ASTM A106 B and A53 B.
    • PSL2: A higher specification level than PSL1, PSL2 pipes have stricter chemical composition and mechanical strength requirements. They also undergo additional testing methods such as Non-Destructive Testing (NDT), Charpy V-Notch (CVN) Impact Test, and Drop Weight Tear (DWT) Test. API 5L B PSL2 is denoted as API 5L BN/Q/R/M.
  2. Seamless and Welded Pipe Types
    • Seamless Type: Includes hot rolled seamless pipes for diameters above 3 inches and cold rolled seamless pipes for diameters below 3 inches.
    • ERW Welded Type: Electric Resistance Welded pipes are suitable for diameters below 24 inches.
    • LSAW Type: Longitudinal Submerged Arc Welding pipes are used for outer diameters ranging from 20 inches to 48 inches. This type is also known as JCOE, referring to the pipe manufacturing process shapes (J-shape, C-shape, O-shape) followed by cold expansion.
    • SSAW/HSAW Type: Spiral Submerged Arc Welding or Helical Submerged Arc Welding pipes can have outer diameters up to 100 inches.
