Vinit Stainless is a well-known producer and supplier of stainless steel coupling in Chennai, India. With high concern for quality and accuracy, our stainless steel couplings are designed with high durability and maximum performance for all industrial applications. Intended for connecting two shafts together with the transmission of power, these couplings provide efficient torque transfer as well as alignment. We at Vinit Stainless provide a variety of sizes and customized specifications according to the diverse demands of our clients. Our products are produced under stringent quality conditions, thus we are a renowned name in stainless steel component supply all over India.
Stainless steel couplings are normally produced using grades like SS 304 or SS 316, providing good corrosion resistance and tensile strength. The metal content consists of 18-20% chromium and 8-12% nickel for SS 304, whereas SS 316 consists of 16-18% chromium, 10-14% nickel, and 2-3% molybdenum. These couplings show tensile strength up to 515 MPa and yield strength of approximately 205 MPa, providing long life in service and excellent mechanical reliability. The high hardness, fatigue strength, and capability to withstand operating temperatures make them a perfect fit for harsh industrial environments.

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.
Stainless steel couplings find extensive application in mechanical and industrial systems for joining two rotating shafts and casting torque and motion between the shafts. They find frequent usage in pumps, compressors, conveyors, and motors in industries like oil and gas, food processing, pharmaceuticals, and water treatment. The corrosion-resistant quality of stainless steel couplings makes them ideal for marine and chemical environments. These couplings help to align shafts, dampen vibration, and also take up small misalignments, hence prolonging the life of equipment. Vinit Stainless couplings offer functional reliability and long-term economy in demanding operating environments
