Seamless Pipe & Tubes

Buy Duplex 2205 Tube , Have difficulty to find Alloy 2205 Seamless Pipe in tough sizes ? Call Tu-lok now

Duplex S31803 Seamless Pipe displays higher resistance to pitting and crevice corrosion due to the presence of chromium, nitrogen, and molybdenum even after being exposed to acidic and oxidizing solutions. SAF 2205 Pipe can be used in high pressure storage tanks, pressure vessels, heat exchangers, and oil and gas pipelines. Duplex 2205 Tubing is also used in cargo boxes for shipping and food processing equipment. Duplex Stainless Steel Pipe Schedule Chart displays the various sizes that these pipes are available in along with their diameter and wall thickness. For instance Duplex, Ss Pipe that is round in shape can have an outer diameter range from 6 mm to 630 mm and the wall thickness range from 0.5 mm to 30 mm.

Duplex Steel Pipe has the ability to resist chloride ion related stress corrosion and is used in rotary shafts, blades, press rolls, impellers, etc. Duplex Stainless Steel Pipe Specification includes ASTM and ASME SA. Duplex Stainless Steel Pipe Weight depends upon the size of the pipe and is characterized by high yield strength. Whereas the Duplex Stainless Steel Pipe Grades specifies the type of material used in it and the proportion of it. For instance, Werkstoff Nr. 1.4462 Pipe is made up of 22% chromium, 5-6% nickel, and 3% molybdenum. Astm A789 Duplex Stainless Steel Welded Pipe manufactured by us follows the international standards and specifications of grading. We use ultra modern technology and equipment to produce Asme Sa789 Duplex Pipe in large quantities and store them this helps us in catering to large orders without any delay.

What is Duplex 2205 Pipe ?

Pipes and tubes made up of various materials are available in the market. Stainless Steel is the most common one that is available in ferritic and austenitic. Duplex 2205 Pipe is one such type that has a microstructure of both ferritic and austenitic. Duplex Stainless Steel 2205 Pipe has high strength, along with good impact toughness. Duplex Stainless Steel Pipe Manufacturer recommends these due to their resistance to local corrosion. It is not advisable to use Duplex 2205 Seamless Pipe at a temperature above 572 degrees F. when compared to other austenitic steel grade Duplex 2205 Tube displays superior corrosion resistance.
