Swagelok SWS-40CI-48 Orbital Welding System Cajon Series

Swagelok SWS-40CI-48 Orbital Welding System, Cajon Series, is a Series 40 weld head configured for a 3-inch pipe collet (76.2 mm). The 3-inch pipe collet is identified by ordering number SWS-40CI-48, and two collet halves are required per side plate. Series 40 weld heads cover outside diameters from 1-1/2 to 4 inches (38.1 to 101.6 mm), enabling use across mid-range piping projects; tube collets are available in multiple sizes to fit different OD and can be exchanged easily for quick diameter changes. The tube and pipe collets hold components rigidly during welding, and the system design facilitates pre-tacking of the weld joint as part of the process. The Cajon Series designation ties this configuration to Swagelok’s family of orbital welding fixtures that emphasize alignment stability and repeatable GTAW welds in fluid-system assemblies.
