从China供应商批发进口Alloy Steel Elbows — FOB条款

Alloy steel elbows from Shijiazhuang Dingsheng Pipe Co., Ltd are forged piping components designed to redirect flow in high-pressure, high-temperature fluid transport systems. The elbows are produced to ASTM A234 standard in grades WP11 and WP22, with available configurations including 90-degree and 45-degree angles. Sizes span from 1/2 inch to 48 inches, with wall thickness ratings from sch XS through XXS. The material composition follows standard chrome-moly alloy specifications, delivering creep resistance and structural integrity at elevated operating temperatures typical of power generation and refinery service.

The WP11 grade contains 1.25% chromium and 0.44% molybdenum as standard, while WP22 grade carries 2.25% chromium and 1% molybdenum for more severe service conditions. Both grades undergo normalizing and tempering heat treatment as part of standard manufacture. Dimensional conformance to ASME B16.9 and ANSI B16.25 ensures compatibility with butt-weld piping systems. Surface finish is typically black oxide or bare metal, with bevelled ends prepared for welding in accordance with standard practice. The elbows are supplied in wooden pallet packaging for containerized export, though exact packaging configurations should be confirmed with the supplier for specific orders.

Primary applications include oil and gas transmission pipelines, petrochemical process plants, thermal power stations, and refinery reactor circuits. Buyers are typically EPC contractors, maintenance procurement teams, and industrial distributors serving ASEAN, Middle East, and African markets.
