Import Boiler Tube A179 &A192 — Buy in Bulk from Supplier in China

ASTM A179 and A192 carbon steel boiler tubes from Wuxi Sunrising Steel Co., Ltd are seamless cold-drawn tubes engineered for heat exchanger and condenser service under high pressure. The A179 grade covers minimum-wall-thickness tubes for low-carbon steel applications, while A192 addresses higher carbon content for elevated pressure and temperature conditions. Both grades are manufactured to ASTM specifications with typical outside diameters ranging from 6.35 mm to 76.2 mm and wall thicknesses from 0.89 mm to 9.70 mm, though buyers should confirm exact dimensional availability directly with the supplier.

The material composition for A179 requires 0.06-0.18% carbon with 0.27-0.63% manganese, typical of low-carbon killed steel, whereas A192 specifies 0.06-0.18% carbon and 0.27-0.63% manganese but with higher tensile strength requirements, minimum 325 MPa for A179 and 414 MPa for A192. Hardness limits are set at HRB 72 for A179 and HRB 77 for A192. The tubes undergo flattening, flaring, and flange tests as standard mechanical verification. Corrosion resistance derives from the carbon steel matrix rather than alloying, making proper water chemistry control essential in service.

These boiler tubes serve power generation plants, oil and gas refineries, petrochemical facilities, and general industrial boiler systems where efficient heat transfer under pressure is critical. Buyers include boiler original equipment manufacturers, maintenance contractors, and large facility operators. Wuxi Sunrising Steel Co., Ltd lists FOB and CIF incoterms with letter of credit or telegraphic transfer payment options. The response rate shows 0.00% with zero average response hours recorded, so direct outreach to confirm stock, mill test certificates, and current production schedules is advisable before placing orders.

Wuxi Sunrising Steel Co., Ltd operates from Room 532, No.999, Xihu West Road in Wuxi, Jiangsu Province, China, postal code 214011. The company is classified under an imported supplier tier with harbor trust level, indicating it sources material from mills rather than manufacturing directly. The response rate stands at 0.00% with zero recorded average response hours, which signals that prospective buyers should not rely on rapid automated replies and should instead make direct contact through multiple channels to establish communication.

The listing presents the supplier as offering ASTM A179 and A192 boiler tubes with flexible minimum order quantities, though no specific MOQ figure is stated in the source data. Payment terms mentioned include letter of credit and telegraphic transfer, with shipping under FOB or CIF incoterms. The supplier profile does not disclose factory ownership, production capacity, headcount, revenue, clientele, or certification holdings beyond general references to ISO and SGS. Buyers should independently verify mill test certificates, third-party inspection reports, and the actual manufacturing source of any tubes offered.
