Swagelok SWS-40CI-64 Orbital Welding System 4 Inch Pipe

Swagelok SWS-40CI-64 Orbital Welding System is a Series 40 weld head configured for welding 4-inch pipe (outside diameter 101.6 mm) and uses an on-center collet to align the tube ends and hold components rigidly during welding. Series 40 weld heads cover outside diameters from 1-1/2 to 4 inches, and the SWS-40CI-64 designation identifies the 4-inch collet configuration that secures the joint with Swagelok tube collets to maintain weld geometry. The orbital system relies on gas tungsten arc welding (GTAW) in an automated head to produce clean, repeatable welds in stainless steel and other tubing used for fluid systems. Common applications include high-purity fluid systems in semiconductor manufacturing and other industries where a robust, repeatable 4-inch pipe weld is required and Swagelok compatibility with fittings and tube hardware is advantageous.
