🔹 Socket Weld Cap 

Socket Weld Caps are high-pressure pipe fittings designed to seal the end of small-diameter piping systems. They provide strong, leak-proof welded connections and compact installation, ensuring safety and reliability in industrial pipelines.

• Designed to close off the end of a pipeline or temporarily seal a line during maintenance.

• Ideal for high-pressure systems, preventing leaks, corrosion, or contamination.

Manufactured according to ASME B16.11 and applicable GOST standards, these caps deliver dimensional accuracy, mechanical strength, and long-term durability.

Product Range

• SW End Cap – standard closure for small-diameter pipelines.

• Available in multiple sizes and pressure classes to accommodate different industrial requirements.

Suitable for pressure classes 3000#, 6000#, 9000#, and pipe sizes from 1/8" to 4". Compatible with carbon steel, stainless steel, and alloy steel.

Key Features

• High-pressure rated – withstands up to 9000#, ensuring leak-free sealing.

• Compact design – allows fast installation in confined spaces.

• Durable construction – precision machining and strict quality control for reliable performance.

• Smooth internal surface – prevents turbulence and corrosion at the pipe end.

• 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 Caps 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

Ideal for pipeline termination, maintenance isolation, or temporary sealing during process adjustments.
