从China供应商批发进口A106 B Steel Bend — FOB条款

Cangzhou Yongwang Pipeline Manufacturing Co., Ltd. produces ASTM A106 Grade B seamless carbon steel bends for high-temperature, high-pressure piping systems in oil and gas, petrochemical, and power generation applications. These buttweld fittings are manufactured to ASME B16.49 and ASTM A106 specifications, with sizes ranging from 2 to 24 inches and angles including 90 and 180 degrees. The seamless construction ensures superior fluid flow characteristics and reduced leak risk compared to welded alternatives.

The material specification is carbon steel ASTM A106 Grade B, a standard killed steel with minimum tensile strength of 415 MPa and yield strength of 240 MPa at room temperature. This grade is specifically formulated for elevated temperature service, with allowable stresses defined up to approximately 540 degrees Celsius depending on application codes. The typical chemical composition includes maximum 0.30% carbon, 0.10-0.35% silicon, 0.29-1.06% manganese, with controlled residuals of phosphorus and sulfur. Wall thickness follows standard pipe schedules, with common schedules including SCH40, SCH80, SCH120, and SCH160 depending on pressure class requirements.

Buyers for this product include EPC contractors, refinery operators, pipeline construction firms, and process plant engineers across global energy markets. Typical procurement involves specification to ASME B16.49 for induction bends or ASTM A106 for material certification, with additional testing often including radiographic examination, ultrasonic testing, or hydrostatic testing per project requirements. Buyers should confirm with Cangzhou Yongwang Pipeline Manufacturing Co., Ltd. the exact bend radius (typically 3D, 5D, or custom), tangent length, heat treatment condition, and any required third-party inspection or material test certificates before placing orders.

Cangzhou Yongwang Pipeline Manufacturing Co., Ltd. is located in Yanshan County, Cangzhou, Hebei Province, China, with postal address 061300. This places the company within China's concentrated pipeline manufacturing cluster in Hebei, a region with established steel processing and pipe fitting production infrastructure. The supplier's tier is classified as imported, with a harbor trust tier designation, indicating baseline marketplace presence without extensive verification signals. The response rate is recorded at 0.00% with zero average response hours, which buyers should note when evaluating communication reliability for urgent enquiries or technical clarifications.

The company profile does not disclose manufacturing certifications, quality management system registrations, export licence details, or specific production capacity figures. No information is provided about years in operation, employee count, annual revenue, or named client references. Buyers should therefore conduct independent due diligence, requesting documented evidence of ASTM A106 material certification capability, ASME B16.49 manufacturing compliance, and any third-party quality system audits (such as ISO 9001) directly from the supplier before commitment. The listing positions the company as a manufacturer of standard and custom steel bends for global industrial markets, but verification of actual production scope and inspection capabilities remains the buyer's responsibility.
