Socket Weld Coupling (Full / Half)

🔹 Socket Weld Coupling (Full / Half)

Product Overview

Socket Weld Couplings (Full and Half) are high-pressure pipe fittings designed to connect two pipes securely in small-diameter piping systems. These fittings provide strong, leak-proof welded joints, compact installation, and reliable performance under high-pressure conditions.

  • Full Couplings join two pipes of the same diameter, providing a seamless, continuous flow.

  • Half Couplings allow connection to a smaller branch or are used where installation space is limited.

Manufactured according to ASME B16.11 and GOST standards, these couplings ensure mechanical strength, dimensional accuracy, and long-term reliability in demanding industrial pipelines.

Product Range

  • SW Full Coupling – standard connection for equal-diameter pipelines.

  • SW Half Coupling – for connecting to smaller branches or for compact installations.

Suitable for pressure classes 3000#, 6000#, 9000#, and pipe sizes from 1/8" to 4". Available in carbon steel, stainless steel, and alloy steel for diverse industrial requirements.

Key Features

  • High-pressure rated – withstands pressures up to 9000#, minimizing leak risk.

  • Full and Half options – flexible connection solutions for different pipeline layouts.

  • Compact design – ideal for tight spaces and small-diameter piping.

  • Smooth internal bore – ensures stable flow and reduces turbulence.

  • Durable construction – precision machining, strict quality control, certified materials.

  • Multi-standard compliance – ASME B16.11, GOST; suitable for international industrial pipelines.

Materials

  • Carbon Steel: ASTM A105, A350 LF2 or equivalent

  • Stainless Steel: ASTM A182 F304 / F316 / F316L

  • Alloy Steel: F11, F22 or equivalent

  • Special materials available upon request

  • EN 10204 3.1 material certificates available

Applications

Socket Weld Couplings are widely used in:

  • Oil & Gas pipelines (upstream & downstream)

  • Chemical and petrochemical plants

  • Power generation facilities

  • Shipbuilding and offshore projects

  • Industrial small-diameter high-pressure pipelines

Full couplings are ideal for continuous pipelines, while half couplings allow branching or compact installations without cutting existing pipes.

Delivery & Support

  • In-stock availability ensures fast delivery for urgent projects.

  • Custom manufacturing for special diameters, pressure ratings, or materials.

  • Technical assistance from engineers to select the right coupling for your system.

  • OEM and bulk orders supported.
