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.To ensure the highest surface quality in all of our sanitary tubing, the tests, combined with specific raw material requirements, eddy current testing at the tube mill, and tighter OD and wall tolerances allow us provide a more consistent superior quality product.

Metallica is a familiar production house of Stainless Steel Tubes, which is used in nuclear fuel reprocessing, acid production, and oil / gas piping. Few exact rules exist for selecting through-hardening or surface-hardening grades, where tungsten and vanadium will form carbides, both of which increase the hardness and stability of the finished product.
We have emerged as the leading producer and supplier of these Stainless Steel Seamless Tubes, which have high creep and oxidation resistance. While in a molten state, these steels are exposed to a vacuum which removes hydrogen and, to a lesser degree, oxygen and nitrogen. Stainless Steel Welded Tubes offered by Metallica provides highly safe and reliable operations.
Note:
- Mill test certificates will be issued according to EN10204 3.1.
- All tubes shall be supplied as per applicable to ASTM Specification.
Other different shapes
Oval Tube; Hexagon Tube; Flat Oval Tube; Fan Shaped Tube; Arched Tube; Rectangle; Plum Blossom Shaped Tube; U shape tube; Square, Capillary, Triangle, Decorative, Handrails etc.
