Detailed Introduction
American standard elbows are pressure-bearing pipe fittings used in American standard pressure piping systems to change the direction of media flow. They are formed by forging or seamless pushing processes, with dimensions in inches, and bevels, tolerances, non-destructive testing, and heat treatment are executed in accordance with American standard specifications. Conventional butt welding elbows comply with ASME B16.9, carbon steel pipes match ASME B36.10M, stainless steel matches ASME B36.19M, and high-strength pipe fittings refer to MSS SP-75. The specification system covers 1/2 inch to 48 inches, angles include 45°, 90°, 180°, bending radii include 1.5D long radius and 1.0D short radius, and wall thickness grades include Sch10, Sch40, Sch80, Sch120, Sch160, and XXS. Mainstream materials include A234 WPB carbon steel, A403 WP304/WP316L stainless steel, A234 WP11/WP22 chrome-molybdenum alloy steel, and S32205 duplex steel. Products are exported to overseas engineering projects in North America, the Middle East, Southeast Asia, etc., and can be supplied as complete sets with American standard flanges, American standard branch outlets, American standard tees, and other pipe fittings. Regular stock specifications have a minimum order of 1 piece, and packaging and shipping can be completed within 24 to 48 hours after order confirmation.
- Complies with ASME B16.9, B36.10M, B36.19M, and MSS SP-75 standards, with inch dimensions, Sch wall thickness, bevels, and material grades aligned with international engineering drawings, suitable for selection in genuine American standard EPC projects.
- Specifications cover 1/2 inch to 48 inches, angles include 45°, 90°, 180°, bending radii include 1.5D long radius and 1.0D short radius, and wall thickness ranges from Sch10 to XXS, and can be matched according to project drawings.

| Packaging | American standard elbows adopt international foreign trade dedicated standardized export packaging, accommodating ocean shipping, multi-country customs inspection, and overseas engineering high-end acceptance standards, completely preventing bumps, bevel damage, rust, and deformation throughout the entire process. Small-diameter precision elbows uniformly use thickened plastic protective caps to seal pipe ends, preventing debris entry and bevel bumps, with the exterior wrapped in multiple layers of waterproof stretch film and bubble film, achieving all-round shockproof and moisture-proof protection. Small and medium specifications are packed in batches into thickened export cartons, with categorized labeling of specifications, materials, standards, and batches, avoiding mixed loading and confusion. Large-diameter, thick-wall, high-pressure American standard elbows use multi-layer rainproof and rust-proof wrapping film for overall wrapping, with reinforced protection at pipe ends, and the bottom uses fumigation-free solid wood pallets for fixation, with overall steel strapping for tightening and reinforcement, preventing displacement and deformation from ocean shipping turbulence. Carbon steel products are sprayed with anti-rust oil |
