API 5L Grade B Pipe

API 5L Grade B ERW pipes are made from a high-quality steel alloy, containing elements like carbon, manganese, copper, nickel, chromium, molybdenum, phosphorus, sulfur, and vanadium. This combination enhances the strength and durability of these pipes, making them ideal for rigorous applications. Amardeep Steel is a leading supplier and manufacturer of API 5L Grade B Seamless and Welded Pipes, offering various sizes and specifications to meet industry requirements.

Specifications and Applications

Available in seamless and welded forms, API 5L Grade B pipes are designed for oil, petroleum, and natural gas transmission lines. These pipes are widely used in sectors such as oil refineries and petrochemical plants, where dependable performance is crucial. With outer diameters ranging from ½ inch to 48 inches, these pipes offer versatility for different installation needs.

PSL-1 and PSL-2 Specifications

API 5L Grade B pipes come in two specification levels: PSL-1 and PSL-2. While PSL-1 provides a standard quality level, PSL-2 has more stringent requirements for chemical composition, mechanical properties, and notch toughness, with additional non-destructive testing (NDT) for applications demanding high reliability. PSL-2 pipes are particularly suited for critical uses that require enhanced quality.

Key Features and Benefits

As a versatile and durable option, ASTM A53 Grade B pipes serve numerous mechanical and industrial applications, including:

Broad Application Range: Ideal for transporting oil, gas, and petroleum over long distances.
Flexible Specifications: Available in various NPS/NB dimensions and thicknesses to match specific client needs.
Certified and Tested: SAll pipes include full traceability and mill test certification according to EN 10204 3.1 for compliance and assurance.
Quality Control: Each pipe undergoes strict inspection by our in-house quality control team before shipment, ensuring it meets client requirements.
