  • Stainless steel capillary tube is one type of the stainless steel special shaped tube
  • Capillary stainless steel tubing is the standard specification for the welded/ERW, seamless and heavily cold worked welded austenitic and ferritic stainless steel. Our product range for stainless steel capillary pipes and tubes include all types such as Seamless, Welded, ERW, and EFW.
  • The inside surface of the tubes is free from oil, grease and other particles. This ensures, for example, an optimized and even flow of liquids and gases from the sensor to the measuring instrument.
  • Stainless tubing provides Good corrosion resistance,Heat resistance, Softness, Tight tolerances, Rust resistant, Withstand high weight, Easy to clean. Stainless tube is much lighter than its equivalent bar shape and therefore more practical for use in fabrication where weight is a concern.

Quality Tests for Stainless Steel Capillary Pipes & Tubes

From the receipt of raw materials to the final inspection of the finished products – we do everything we can to ensure our customers receive only the very best quality. Of course, all tubes of a non-destructive and / or destructive testing may be subjected. We have the HP-0 approval by the TÜV and also meet many other quality requirements. Final Inspection:- IGC Test Dimensions Surface, Physical Testing, Grade Check, Product Analysis, Hardness Test, Bend Test, Chemical And Mechanical Analysis, Pitting Resistance Test, Intergranular Corrosion Test, Water Pressure, Crack Detector.

Heat Treatment (Annealing) for Stainless Steel Capillary Pipes & Tubes

304/304L is not hardenable by heat treatment. Cold working increases tensile strength and hardness. Annealing range is between 1850° and 2050°F. Cool rapidly. Water should be used for heavier sections; air for lighter sections. The stress relieving range is between 400° and 750°F

Surface Finishes for Stainless Steel Capillary Pipes & Tubes

Seamless, Welded, Brushed, Pickled, Solution Annealed and Pickled up to O.D. 219.1mm, Polished Grit 120 – 600, Mirror Polished. Other finishes available upon request.

Flattening Test for Stainless Steel Capillary Pipes & Tubes

For material heat treated in a continuous furnace flattening tests shall be made on a sufficient number of pipes to constitute 5 % of the lot, but in no case less than 2 lengths of pipe.

Markings for Stainless Steel Capillary Pipes & Tubes

Bright annealed tubing is line–stenciled with OD, wall, ASTM specifications, size, grade, heat number, production date and time. OD polished tube is marked on one end of each tube with a removable label stating ASTM specification, manufacturer, grade and heat number. Continuous line stencil available on request.

Different wall thickness, materials and surfaces as well as lengths can be produced on inquiry.
