🔹 Socket Weld Union

Product Overview

Socket Weld Unions are high-pressure pipe fittings designed to connect and disconnect small-diameter pipelines easily without cutting the pipe. They provide strong, leak-proof welded connections, while allowing maintenance, replacement, or reconfiguration of piping systems with minimal downtime.

• Ideal for high-pressure systems, ensuring reliable sealing and long-term durability.

• Designed for quick assembly and disassembly, making pipeline maintenance faster and more efficient.

Manufactured according to ASME B16.11 and applicable GOST standards, Socket Weld Unions deliver mechanical strength, dimensional accuracy, and dependable performance in demanding industrial pipelines.

Product Range

• SW Union – standard union for small-diameter pipelines.

• Available in multiple sizes and pressure classes to suit different industrial applications.

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#, reducing leak risk.

• Quick assembly/disassembly – facilitates maintenance, inspection, and pipeline reconfiguration.

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

• Compact design – space-saving installation for small-diameter pipelines.

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

• 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
