Rishabh Steel Industries is One Of The Largest Stainless Steel Threaded Full Coupling Manufacturers in India. ASME B16.11 Threaded Full Coupling has excellent resistance to chloride-ion stress-corrosion cracking, and as well shows appropriate resistance to a number of oxidizing environments. ANSI B16.11 Forged NPT Threaded Full Coupling is very much resistant to chemical corrosion and oxidation (corrosion resistant), and has some high stress-rupture effectiveness and low creep rates under high stresses at temperatures after suitable heat treatment. Our Forged Threaded / Screwed Full Coupling are accessible to our valuable customers in different range of diameters (d), wall thicknesses (w) and sizes (nom. Pipe Size) in customized form (as per customer requirment or order) and also at quite affordable rates (Best Price In India). Meanwhile, we offer different types of these fitting such as [We Manufacture And Supply Tee In Other Materials Like :] Stainless Steel Threaded Reducing Coupling, Inconel Threaded Full Coupling, Carbon Steel Threaded Full Coupling, Alloy Steel Threaded Full Coupling, etc.
