1.4541/321 Elbow, ASTM A403 WP321 UNS S32100 SS Long/Short Radius Elbows

WP321 elbows comes in both long and short radius options. This elbow is suitable for various piping systems that require reliable and durable components. The use of high - quality stainless steel ensures good corrosion resistance, which helps to extend the service life of the product. Its standard - compliant design makes it easy to install and integrate into different industrial applications. Whether for chemical, petroleum, or other related industries, this elbow can meet different engineering needs.

Surface treatment for 1.4541/321 Elbow:

Buttweld fittings, BW fittings, tees, elbows and reducers are given a standardized sandblasted surface treatment, which enhances the corrosion resistance of the fittings and ensures a consistent finish. Sandblasting removes contaminants and optimizes adhesion of subsequent coatings or welds. Surface finish inspections include PMI inspections, dimensional and cosmetic inspections to meet ASTM/EN specifications. Laboratory testing verifies mechanical properties and chemical composition, especially for austenitic steels, duplex steels, and nickel alloys.

Production advantages of MTSCO Concentric Reducers:

-Since 2010, MTSCO have held a controlling stake in Hongdi Pipe Industry through cooperation, obtaining ISO/PED/CRN/TS certifications and achieving a vertically integrated supply chain.

-Precision manufacturing is carried out using CNC lathes, 1000-ton hydraulic presses, and automated laser cutting systems.

-Our raw materials come from large factories such as Baosteel, TSINGSHAN, Yongxin... Each batch of raw materials requires MTC and PMI to ensure the quality of the raw materials. After the raw materials arrive, we conduct inspections such as PMI again to ensure they meet the requirements.

-Digital documents at each production stage supervised by factory engineers enable full-process traceability.

-Mandatory 100% pre-shipment inspections are carried out, including dimensional checks, non-destructive testing (ultrasonic testing/radiographic testing), and mechanical property testing.
