ASEA METAL supplies butt weld fittings (elbow, tee, reducer, cap, stub end) in Korea for demanding piping service. We support large-size fittings, multiple material grades, and inspection/document packages aligned to your project ITP.
We manufacture butt weld fittings in Korea for piping packages and pressure systems. Typical stainless fittings include ASTM A403 WP316L and ASTM A403 WP304L, with carbon steel fittings such as ASTM A234 WPB supplied per specification. Dimensional standards (e.g., ASME B16.9) and NDT scope are aligned to project requirements. We support MTC (EN 10204 3.1 / 3.2) and traceability documentation for export deliveries. ASEA METAL is a Korean manufacturer prepared to quote single items or full fitting lists.
