从China供应商批发进口4"-10"Sch40 Smls Pipes — FOB条款

These seamless pipes are manufactured in 4 to 10 inch outer diameters to Schedule 40 wall thickness, using carbon steel conforming to ASTM A106 Grade B or API 5L Grade B for high-pressure service. The seamless construction ensures uniform wall thickness and eliminates weld seams, which is critical for fluid transmission under extreme temperatures and pressures in oil, gas, and petrochemical applications.

The material grade ASTM A106 B provides a minimum yield strength of 240 MPa and tensile strength of 415 MPa, with typical elongation of 22%. API 5L Grade B offers similar mechanical properties and is standard for pipeline transportation systems. Both grades are typically supplied in hot-rolled or cold-drawn conditions, with a standard length of 6 metres, though custom lengths are available upon request.

These pipes are primarily sourced by EPC contractors, pipeline operators, and industrial plant developers for use in refineries, power stations, and offshore platforms. Bulk procurement is common, with standard packaging in bundles secured with steel straps and end caps to prevent damage during transit. Buyers are advised to confirm the exact heat treatment and hydrostatic test pressure, as these are not specified in the listing.

Liaocheng Jingxin Steel Pipe Manufacturing Co.,Std operates from Wuyishan Road in the Economic Development Zone of Liaocheng, Shandong Province, China. The company specialises in seamless carbon steel pipes for industrial applications, with a focus on oil, gas, and petrochemical sectors. Its harbor-tier trust rating reflects verified operational presence, though the listing does not provide response rate or average response time data.

The supplier’s profile does not disclose production capacity, certifications, or client references, so buyers should request these details directly. The company’s address and location in Shandong, a key steel production hub, suggest regional expertise in pipe manufacturing for domestic and export markets.
