Stainless Steel Coupling

Product Details:

A Threaded Coupling is a straight pipe fitting used to connect two male-threaded pipes together. In Stainless Steel, these couplings provide excellent corrosion resistance and mechanical strength, making them suitable for harsh environments, including chemical, marine, and industrial applications.

• Oil & gas pipelines

• Water and wastewater treatment

• Chemical and petrochemical plants

• Fire protection systems

• Food and beverage processing

• Compressed air systems

• Marine and offshore installations

• Easy to install and disassemble

• Leak-proof under moderate pressure (with sealant)

• Reusable and cost-effective

• No welding required

• Corrosion and chemical resistance (especially in SS 316)

Product Details:

A Stainless Steel Full Coupling is a cylindrical pipe fitting used to connect two pipes or fittings of the same diameter in a straight run. It features internal threads or socket weld ends on both sides, providing a strong, leak-tight joint for high-pressure or corrosive service applications.

• Material:

  • Stainless Steel 316 (for superior corrosion resistance)

  • Stainless Steel 304 (for general-purpose use)

  • Conforms to ASTM A182 F316/F304

• Connection Types:

  • Threaded (NPT or BSPT) – female threads on both ends

  • Socket Weld – recessed socket for welding on both ends

• Sizes:

  • From 1/8" to 4" NPS (Nominal Pipe Size)

  • Common sizes: 1/2", 3/4", 1", 2"

• Pressure Classes:

  • Threaded: Class 2000

  • Socket Weld:

    • Class 3000

    • Class 6000

    • (Higher ratings available on request)

• Standards:

  • ASME B16.11 – Forged Fittings, Socket-Welding and Threaded

  • MSS-SP-79, MSS-SP-83

  • ASTM A182, ASTM A105, NACE MR0175 (when applicable)

• Oil and gas pipelines

• Chemical processing

• High-pressure steam and condensate lines

• Hydraulic systems

• Water treatment plants

• Food, beverage, and pharmaceutical (if sanitary-grade)

• Leak-tight connection under pressure and thermal cycling

• Resistant to corrosion, chemical attack, and temperature extremes

• Easy to install and align

• Suitable for permanent connections in high-integrity systems

Product Details:

• SS: Stainless Steel

• 316L: A low-carbon version of 316 stainless steel

  • High corrosion resistance, especially against chlorides and acidic environments

  • Commonly used in marine, chemical, pharmaceutical, and food processing industries

  • "L" indicates low carbon content, which improves weldability and reduces the risk of carbide precipitation

• A full coupling is a short length of pipe with internal threads (or socket weld ends), used to connect two pipes of equal diameter

• Threaded or Socket Weld versions are common

  • Threaded coupling: Internal threads (NPT or BSP)

  • Socket weld coupling: Plain bore for socket welding to the pipe

• Oil & gas pipelines

• Chemical processing lines

• Water and wastewater systems

• Food-grade piping setups

• Pharmaceutical cleanrooms

Product Details:

A Stainless Steel 304 Full Coupling is a forged pipe fitting used to join two lengths of pipe in a straight, in-line configuration. It has female threads or socket weld ends on both sides and is suitable for low to high-pressure piping systems, especially where corrosion resistance is essential.

• Material:

  • Stainless Steel 304

    • Austenitic stainless steel with good corrosion resistance

    • Ideal for general-purpose applications in non-aggressive environments

  • Conforms to ASTM A182 F304 for forged fittings

• Types:

  • Threaded Full Coupling – female NPT or BSPT threads on both ends

  • Socket Weld Full Coupling – socket ends for pipe insertion and fillet welding

• Size Range:

  • Available from 1/8" to 4" Nominal Pipe Size (NPS)

  • Common sizes: 1/2", 3/4", 1", 2"

• Pressure Ratings:

  • Threaded: Class 2000

  • Socket Weld:

    • Class 3000 (standard)

    • Class 6000 (for high-pressure service)

• Standards:

  • ASME B16.11 – Forged Fittings, Socket-Welding and Threaded

  • ASTM A182 F304 – For forged stainless steel components

  • MSS-SP 79, MSS-SP 83

• Water and wastewater systems

• Food and beverage processing

• HVAC and compressed air lines

• Chemical and petrochemical systems

• Marine and offshore applications

• General industrial piping

• Corrosion-resistant in mildly corrosive environments

• Strong and durable for high-pressure systems

• Easy to install for permanent or temporary service

• Compatible with NPT/BSP threaded pipes or socket weld pipes
