从China供应商批量进口A106 Smls Steel Pipes

A106 Smls Steel Pipes are seamless carbon steel pipes manufactured to ASTM A106 standard, a specification for seamless carbon steel pipe for high-temperature service. Hebei Steel Piping & Equipment Co., Ltd. supplies these pipes from its base in Cangzhou, Hebei Province, a region with deep roots in China's steel pipe manufacturing cluster. The pipes are produced without longitudinal weld seams, giving uniform mechanical properties around the circumference and eliminating the weakest point found in welded pipe.

The material conforms to ASTM A106 Grade A, B, or C, with Grade B being the most commonly supplied for pressure piping applications. Typical chemical composition includes maximum 0.30% carbon for Grade B, 0.29-1.06% manganese, and controlled levels of phosphorus and sulphur. Mechanical properties typical for Grade B include minimum tensile strength of 415 MPa and yield strength of 240 MPa. The seamless manufacturing process involves piercing a solid billet to form a hollow shell, then elongating and reducing to final dimensions, hot finishing, and heat treatment by full annealing, normalising, or normalising and tempering.

These pipes serve oil and gas transmission pipelines, refinery process piping, power plant steam lines, and boiler feedwater systems where pressure integrity at elevated temperature is critical. Buyers include EPC contractors, petrochemical operators, and mechanical contractors in Southeast Asia, the Middle East, and Africa. Hebei Steel Piping & Equipment Co., Ltd. lists flexible minimum order quantities. The supplier holds ISO certification, though buyers should verify current certificate scope and validity directly with the company before placing orders.

Hebei Steel Piping & Equipment Co., Ltd. operates from Wuliyao Industrial Zone in Cangzhou, Hebei Province, postal code 061300. Cangzhou is one of China's principal concentrations of steel pipe manufacturing, with extensive clustering of mills, coating facilities, and export logistics. The supplier's tier is marked as imported, and its trust tier is harbour, indicating a baseline level of platform verification. The response rate is shown as 0.00 with zero average response hours, which suggests either a new listing or that response data has not yet accumulated. Buyers should treat this as an unverified communication pattern and initiate direct contact to gauge current responsiveness.

The company profile does not disclose year of establishment, production capacity, number of employees, annual revenue, nor named client references. No specific fabrication equipment, inspection laboratory accreditation, or third-party audit certifications are listed beyond a general ISO reference. Buyers should request a current ISO 9001 certificate copy, verify scope of certification, and ask for mill test certificates (MTC) from recent production to assess quality system robustness. The address places the supplier within an established industrial zone, which may facilitate third-party factory audits if buyers choose to conduct them.
