Material Description:

 

It is a special austenitic stainless steel. The urea grade stainless steel special for urea production mainly includes 316L UG, 00Cr25Ni22Mo2N (2RE69).

Urea production is synthesized from carbon dioxide and ammonia under the conditions of high pressure (140-250 atmospheres) and temperature 180-210 degrees. The intermediate product, ammonium carbamate, is strongly corrosive to stainless steel, and ordinary stainless steels such as 316L cannot meet its corrosion resistance. The special steel clock developed from this is called urea grade stainless steel.

 

Size Range for tubing:

OD:1/4" (6.25mm) to 8" (203mm)
WT 0.02" (0.5mm) to 0.5"(12mm)
Length: 15m(Max) or as your requirement

 

Process:  
Cold drawn, Cold rolled, Precision Rolled for Seamless Pipe or Tube
Gas tungsten arc welding, Plasma arc welding (PAW),Submerged arc welding (SAW) For Welded Pipe or Tube

Finish:   Annealed & pickled, bright annealing, polished

Ends:   Beveled or plain end, square cut, burr free ,Plastic Cap at Both end

Packing:   Bare packing/bundle packing with woven bag/wooden or steel frame crate packing/plastic cap protection at the both sides of tubes and suitably protected for sea-worthly delivery or as requested.

 

Inspection and Test Procedure

 

1. The grades are 316L UG and 00Cr25Ni22Mo2N, and their chemical composition and mechanical properties should meet the requirements of national standards for qualified urea equipment and materials.

 

2. The metallographic structure of the material is austenite, and the ferrite content is not more than 0.6%.

 

3. The material must pass the test for huey   test, and the test result should meet the national standard requirements for urea equipment and materials.

 

4. The selective corrosion test shall be carried out after huey   test, and the test results shall comply with the national standard requirements for urea equipment and materials.

 

5. The material should also be metallographically inspected and must not contain sigma and metal inclusions, among other requirements.


NOTES :   ALL THE TESTS AND INSPECTION RESULT NEED TO BE SHOWED IN REPORTS ACCORDING TO STANDARD AND SPECIFICATION.
