从China供应商批量进口90°Carbon Steel Elbows Long Radius

Litas produces 90° carbon steel long radius elbows for industrial piping systems, with nominal pipe sizes spanning 1/2 inch to 28 inches. The long radius geometry gives a centre-to-end dimension equal to 1.5 times the nominal pipe diameter, producing gentler flow bends than short-radius equivalents. These elbows are forged or formed from carbon steel grades suited to pressure piping, with wall thicknesses matched to schedule ratings. The source data does not specify exact ASTM grade or schedule range, so buyers should request the mill certification to confirm material compliance.

Carbon steel long radius elbows typically conform to ASTM A234 WPB for wrought fittings, with ASME B16.9 governing dimensions and tolerances. The standard tolerance on outside diameter is ±1% for NPS 1/2 to 4, and ±0.79 mm for end wall thickness. Bevel ends are standard at 37.5° ± 2.5° for butt-weld preparation. Surface finish is typically black oxide or bare metal, with shot-blasted or pickled surfaces available. Heat treatment normalises grain structure after hot forming. Buyers should verify whether Litas supplies elbows in the as-formed or normalised condition, as this affects impact properties for low-temperature service.

These elbows route process piping in oil and gas gathering, chemical processing plants, refinery units, and water treatment facilities. The long radius design reduces erosion and pressure drop in slurry or high-velocity gas lines. Contractors and EPC firms specify them for ASME B31.3 process piping and B31.1 power piping. Litas lists FOB and CIF terms, with letters of credit and T/T accepted. The response rate is currently zero, so direct enquiry by email or phone is advisable before relying on platform messaging.

Litas operates through Tianjin All Best International Ltd, with its factory located in Xiwang New District, Mengcun, Cangzhou, Hebei Province, and a trade office at Sunny Plaza, Huanghe Road, Nankai District, Tianjin 300112. The supplier tier is marked as imported, and the trust tier is harbour. The response rate stands at 0.00% with zero average response hours recorded on the profile, which signals that direct contact methods may be more reliable than platform messaging for urgent enquiries.

The listing presents Litas as offering flexible minimum order quantities and global shipping under FOB and CIF terms, with payment by L/C or T/T. No certifications are named in the source data, so buyers must independently verify mill test certificates, material compliance to ASTM A234, and any third-party inspection reports. The company does not disclose years in operation, annual output, or client references in the provided facts.
