从China供应商批发进口A106 A333 A53 Api5l Pipe — FOB条款

The A106, A333 and A53 API5L carbon steel pipes supplied by Shijiazhuang Xinghao Pipefittings Co., Ltd. are seamless or welded solutions compliant with ASTM and API standards for fluid and gas transmission. These pipes are manufactured from carbon steel grades A106, A333 and A53, each tailored for specific temperature ranges and pressure classes, with A106 suited for high-temperature service up to 425 °C and A333 for low-temperature applications down to -45 °C. The API5L grade variants cover pipeline transportation under standard and sour service conditions, with typical yield strengths ranging from 241 MPa to 448 MPa depending on the class.

The material composition is carbon-manganese steel with typical carbon content of 0.25-0.30% for A106 Grade B, ensuring weldability and impact resistance. Surface finishes include bare, black paint or protective oil coating, while end types are typically beveled or plain for field welding. Standard lengths are 5.8 m to 12 m, with typical outer diameter tolerances of ±0.5% and wall thickness tolerances of -12.5% to +12.5% as per ASTM A530. These pipes are commonly supplied in bundles or as single random lengths, strapped and tagged for traceability.

Primary buyers include EPC contractors in oil and gas, petrochemical plants, power stations and water treatment facilities, where these pipes serve as line pipe for hydrocarbons, steam, water and process fluids. The supplier offers bulk shipments with containerized or break-bulk options, and advises confirmation of incoterms such as FOB Tianjin or CIF to major ports. Typical packaging includes hexagonal bundles with steel straps and wooden skids, while third-party inspection and mill test certificates to EN 10204 3.1 or 3.2 are standard practice for export orders.
