Stainless Steel & Alloy Pipes

ASEA METAL supplies seamless stainless steel & alloy pipes in Korea for petrochemical, power and process projects. Typical supply follows ASTM A312 / ASME SA312 (and duplex projects per request), with MTC (EN 10204 3.1 / 3.2) and inspection options aligned to your specification. We manufacture seamless pipes in Korea for petrochemical and process piping projects. Buyers commonly specify by wall/schedule (Schedule 10S / 40S / 80S) and dimensional practice such as ANSI B36.19, so we align SCH/WT, NPS/OD and tolerance to your piping class. For corrosion resistance, TP316L with 2.5% Min Mo is widely specified and supplied as ASTM A312 TP316L where required. We also support duplex 2205 pipe (S32205) and super duplex S32750 pipe by project RFQ, including ASTM A312 and ASTM A790 as applicable. Inspection scope can include PMI tested pipe and NDT such as UT/ECT (per ITP), with MTC (EN 10204 3.1 / 3.2) for export. If you need project package supply from a Korea pipe mill, share your line list so we can confirm availability and packing.
