مواصفات المنتج:

Reference Standards: Materials, manufacturing, inspection, and general tolerances comply with GB/T 13401-2025 or ASME B16.9-2024; non-standard dimensions for reducing elbows must adhere to approved drawings.
Configuration: 90° or other angles; specify large-end × small-end diameters, bending radius, wall thicknesses at both ends, and center-to-end dimensions.
Connection: Butt-weld; end bevels must match the connecting pipes.
Materials: Carbon steel, stainless steel, or alloy steel; material specifications are selected based on the medium and design temperature/pressure conditions.
Pressure Rating: Requires verification of the reducing transition, wall thinning in the bend zone, and wall thicknesses at both ends; flange pressure classes cannot be directly applied.

نقاط الطلب والقبول:

Ordering/Acceptance: Confirm NPS/DN, port diameters, wall thickness/Schedule, dimensional details, seamless vs. welded construction, material grade, heat treatment, bevel configuration, and non-destructive testing (NDT) requirements; the pressure rating of butt-weld fittings is determined based on material, wall thickness, temperature, and piping design codes.
