Internal Purge Pressure Kits

Proper internal purging plays a critical role in ensuring high-quality, uniform orbital welds, especially in ultrahigh-purity and sanitary applications. The Swagelok internal purge pressure kit contains the components needed to set the flow rate of purge gas so that sufficient internal pressure is created in the weld area.

Features

• Magnehelic® gauge for measuring internal pressure from 0 to 5 in. H₂O (0 to 12.4 mbar)
• Swagelok tube fittings with knurled nuts for 1/4, 3/8, and 1/2 in. weld fittings
• Flow restrictors
• Length of 1/4 in. Tygon® tubing
• Two cases for spare parts
• Carrying case with cavities for optional fittings
• Instructions
• Optional fitting packages available in 1/16, 1/8, 3/4, and 1 in. sizes.

Stainless Steel Flux

Thicker walls require more heat during gas tungsten arc welding. Swagelok stainless steel flux serves as a reactive agent with the arc, enabling operators to significantly reduce bead width and increase penetration by as much as 300 %. By using Swagelok flux, an operator will be able to reduce the amount of heat required for full penetration and maintain the critical phase balance of the SAF 2507.

Features

• Provides deeper penetration, reduced bead width, and reduced heat-affected zone when welding thick-walled tubing.
• Is ideally suited for use with Sandvik SAF 2507™ and other super-duplex stainless steels.
• Allows operators to autogenously weld SAF 2507 and maintain critical phase balance.
• Kit includes 1 oz (30 mL) stainless steel flux, brush, and measuring cup.

Tungsten Electrodes

Swagelok electrodes, available in multiples of 10, provide consistent, repeatable welds. Electrodes consist of 2 % ceriated tungsten, axially ground to rigid specifications.

Gauges

Swagelok arc gap gauges promote precise positioning of the electrode in the rotor to help ensure repeatable welds. The easy-to-use gauges eliminate errors associated with sight and feeler gauge adjustments.

Swagelok centering gauges provide accurate centering of weld components for high-quality welds.

Collets and Fixtures

Swagelok offers a wide range of pipe and tube collets for use with Swagelok weld heads, including fractional, metric and JIS sizes from 1/8 to 4 in. and 3 to 104 mm in size. They are easily changed for varying outside diameters.

A variety of fixtures enable welding of tubing down to 1/16 in. and 2 mm outside diameter, as well as VCR®, VCO®, and Micro-Fit® fittings and select valve bodies with 1/4 in., 3/8 in., and 6 mm tube butt weld end connections.
