Swagelok offers a selection of stainless steel tubing in fractional, metric, and imperial sizes and in accordance with global specifications.

• Seamless stainless steel tubing—fractional, metric, and Imperial sizes
  • Instrumentation grade
  • Chemically cleaned and passivated to comply with ASTM G93 Level A and CGA 4.1
  • Thermocouple-cleaned to meet the cleanliness requirements of ASTM A632-S3
• Welded stainless steel tubing-fractional sizes

304/304L and 316/316L Seamless Instrumentation Grade Tubing

Shop Catalog
304/304L and 316/316L stainless steel standard instrumentation tubing. Sizes: 1/8 to 2 in and 3 to 25 mm.

Ultrahigh-Purity (UHP) and High-Purity Stainless Steel Tubing

Catalog
316L stainless steel. Ultrahigh-purity, coaxial, chemically cleaned and passivated, and thermocouple-cleaned. Ends prepared for orbital welding. Sizes: 1/8 to 2 in and 6 to 18 mm.

304/304L Welded Tubing

Cone and Thread Tubing – IPT Series

• 316/316L stainless steel seamless tubing available cold-drawn
• Sized as nominal OD tubing
• Supplied in random lengths averaging 24 ft (20 to 27 ft)
• Marked to indicate size, material, condition, and heat number
• For use with cone and thread products

Medium-Pressure Tubing – FK Series

For use with Swagelok FK series fittings, choose from heavy-wall annealed or cold-drawn 1/8-hard tubing. Cold-drawn 1/8-hard is more robust and allows for reduced wall thickness and enhanced flow through the same diameter tube.

Features

• 316/316L stainless steel seamless tubing available annealed or cold-drawn
• Sized as true OD tubing.
• Supplied in fractional lengths of 20 ft. and metric lengths up to 6 meters
• Marked to indicate size, material, condition, and heat number
• For use with Swagelok medium pressure, gaugeable tube fittings and adapter fittings

High-Pressure Tubing – Sno-Trik Series

Connect Swagelok Sno-Trik products with our pre-coned tube lengths of strain-hardened or annealed true OD tubing. Stain-hardened is more robust and allows for reduced wall thickness and enhanced flow through the same diameter tube.

Features

• 316/316L stainless steel seamless tubing available annealed or strain-hardened
• Sized as true OD tubing
• Supplied in lengths of 120 inches
• Available in custom lengths upon request
• Marked to indicate size, material, condition, and heat number
• For use with high-pressure Sno-Trik products

Jacketed Tubing and Insulated Tubing

Catalog
Swagelok® jacketed tubing helps provide increased protection against galvanic and atmospheric corrosion. Swagelok insulated tubing is designed for use in applications such as steam supply, condensate return, and gas and liquid transport lines, where weatherproofing and energy conservation are important. Swagelok insulated tubing offers a cost-effective alternative to field-installed insulation of small-diameter tubing systems.

• Stainless steel tubing available seamless and welded
• Low-temperature PVC jacket helps protect tubing from external corrosion and abrasion
• Fibrous glass insulation reduces heat loss and helps protect personnel
• Insulation contains less than 100 ppm of water-soluble chlorides
• Marked with part number and batch number
• Insulated tubing is available with urethane jacket material and in colors other than the standard black
• Accessories include:   
  • Bending tool
  • Heat-shrink end-seal boots
  • Silicone sealant
  • Jacket patch kit
  • Caps
  • Weatherproof strip insulation

Jacketed, Pre-Insulated Tubing Bundles—Electric-Traced and Steam-Traced

Shop
Swagelok pre-insulated traced tubing bundles provide reliable process temperature maintenance in a variety of analytical and process instrumentation applications, including impulse lines, sample lines, and process lines and provide an economical choice compared to field tracing and insulating. The parallel configuration—process and tracer lines are parallel inside the bundle—allows all tubes to bend together in as little as an 8 in. (20.3 cm) radius in tubing sizes up to 3/4 in. or 12 mm, so the bundle is easier to route and connect in the field than cabled bundles. Also available in multi-jacketed configurations.

• Water soluble chlorides less than 100 ppm
• Absorption-resistant fibrous glass insulation
• Resists wicking
• Accessories include:
  • Bending tools
  • Heat-shrink end-seal and entry-seal boots
  • Jacket patch kits
  • Center line tool
  • Silicone sealant
  •  Thermostats
  • Electric tracers: power connection, tracer termination, and tracer splice/tee connection kits

Specifications

Electric-Traced Tubing

A simple and economical choice for applications where electric tracing is preferred, Swagelok electric-traced bundled tubing maintains consistent temperatures in long, continuous lengths of impulse and sample lines for freeze protection, temperature maintenance, or viscosity control. The standard Raychem® self-regulating tracer lowers heat output as the bundle gets warmer. For more precise temperature control, an optional line-sensing thermostat is available.

• Raychem self-regulating electric tracers
• Tinned copper braided shield
• Fluoropolymer tracer jacket
• ATEX, FM®, and CSA® approved tracer for use in hazardous areas

Steam-Traced Tubing

Swagelok light steam-traced bundled tubing is typically used for freeze protection of instrument impulse lines and analyzer transport lines. It can also maintain temperatures in smaller diameter process lines. The process and tracer tubes are individually insulated to reduce the heat transfer rate, providing a more consistent tube temperature over long tubing lengths.

• Individually wrapped process and tracer tubes reduce heat transfer
• One or two process tubes available as standard

Heavy Steam-Traced

Swagelok heavy steam-traced bundled tubing is typically used to maintain higher process temperature or for viscosity control. Applications can include impulse, sampling, and process lines. The process tubing is in direct contact with the tracer, providing maximum heat transfer to help maintain higher process temperatures.

• Process and tracer tubes are in direct contact to maximize higher heat transfer
