Carbon Steel Pipe Supplier – API 5L, ASTM A106 Standards

Ruixiang Steel is a trusted global carbon steel pipe supplier, delivering high-integrity seamless and welded pipes compliant with API 5L (PSL1/PSL2), ASTM A106 Grade B, and ASTM A53 standards—ideal for oil & gas pipelines, power plants, petrochemical facilities, and water transmission systems.

Our carbon steel pipes are manufactured from high-quality billets using advanced hot-rolling and cold-drawing processes, ensuring excellent mechanical properties, dimensional accuracy, and weldability. Available in sizes from ½" to 48" OD, wall thicknesses up to Sch 160, and lengths of 6m, 12m, or random, we supply both black (uncoated) and protected finishes (epoxy, FBE, or galvanized) based on project requirements.

As an ISO 9001-certified manufacturer based in Shandong, China—just hours from Qingdao Port—we enforce strict quality control at every stage: chemical composition analysis, hydrostatic testing, ultrasonic inspection, and non-destructive testing (NDT). All shipments include mill test certificates (MTCs) and third-party inspection reports (e.g., SGS, BV) upon request.

We specialize in bulk orders for EPC contractors, pipeline developers, and industrial distributors worldwide. Custom beveling, threading, coupling, and bundling services are available to meet API and project-specific specifications.

With decades of export experience and a reputation for reliability, Ruixiang Steel ensures competitive factory pricing, short lead times, and secure global logistics—backed by responsive technical support.
