Alternative Name: Half Coupling 1 1/4'' BSP 316 Stainless Steel, short threaded half coupling, inox half coupling, acid-resistant coupling, 1.4401, 1.4404, 316L, female threaded coupling, full-port half coupling.
Information
Half Coupling 1 1/4'' BSP 316 Stainless Steel is manufactured from 316 stainless steel, offering excellent corrosion resistance and outstanding weldability.
Half Coupling 1 1/4'' BSP 316 Stainless Steel is widely used by welders because it is ready for welding, allowing fast installation without the need to cut a standard coupling. This reduces installation time and simplifies fabrication.
The coupling is particularly suitable for systems requiring high corrosion resistance. Thanks to the addition of molybdenum, 316 stainless steel provides superior resistance to aggressive chemicals compared with standard stainless steels. A high-quality 316 stainless steel half coupling helps minimise the risk of microcracks in welded joints, ensuring long service life and reliable performance in demanding applications.
Equivalent material grades: DIN 1.4401, 1.4404, SS316, SS316L, AISI 316, AISI 316L.
Applications
- Heat exchangers
- Pharmaceutical equipment
- Dairy processing equipment
- Brewing industry
- Marine fittings
- Coastal structures
- Food processing industry
