Harshita Stainless provides precision Stainless Steel Couplings for safe pipe or tube coupling, manufactured in Delhi, India. With options for threaded, butt-weld, and clamp style couplings, these are made from stainless steel grades 304, 316, and 316L to provide strength and resistance against corrosion. Produced according to international standards ASME, DIN, and ISO, our coupling provides leak-proof connections and easy assembly. Harshita Stainless offers couplings for numerous piping systems throughout India, helping industrial, sanitary, and fluid handling installations with dependable connection solutions.
Made of SS 304, 316, and 316L (chromium 18–20%, nickel 8–12%, molybdenum in 316), the couplings provide tensile strength of 500–750 MPa and yield strength of 200–300 MPa. Precision machining provides exact thread and sealing surfaces. Mechanical toughness provides support for pressure, temperature variations, and corrosion resistance. Couplings support structural loads and thermal growth while staying integral in fluid or gas systems.

Yes, Stainless Steel Couplings can be used for underground applications due to their corrosion resistance, strength, and durability. However, proper installation and maintenance are essential for optimal performance in harsh conditions.
To select the right Stainless Steel Coupling, consider factors like the required size, pressure rating, material grade, environment (corrosive or extreme temperatures), and compatibility with the connected pipes or fittings.
Yes, Stainless Steel Couplings can be used for structural applications due to their strength, corrosion resistance, and durability. They are ideal for connecting structural elements in environments exposed to harsh conditions.
Yes, Stainless Steel Couplings can be welded using appropriate techniques like TIG or MIG welding. It’s important to choose the right filler material and control heat to maintain material integrity.
Utilized commonly in plumbing, hydraulic lines, chemical facilities, sanitary piping, HVAC equipment, and marine systems, stainless steel couplings provide safe connections. They facilitate simple assembly/disassembly for maintenance, installation, and cleaning. Clamped ones are used in food and beverage lines; threaded as well as welded ones connect process pipes. Harshita Stainless distributes these throughout Delhi and India, serving systems that require rapid, effective, and sanitary connections.
