Urea grade stainless steel seamless pipe 304Lmod, 316Lmod, 310MoLN
Urea grade stainless steel pipe 304Lmod, 316Lmod, 310MoLN
We supply urea grade stainless steel pipes including 304Lmod, 316Lmod and 310MoLN (S31050).
The grades are all ultra-pure ferritic stainless steel which can fix the issue of the selective corrosion under high ammonia during the urea reactors. Our annual output of Urea grade stainless steel pipe is over 150 tons and A-one alloy is one of the leading manufacturers of Urea grade pipes.
In the condition of high temperature and high pressure, the urea production process intermediate reactant - ammonium carbamate (urea ammonium carbamate solution), strong corrosive to stainless steel tube, it can destroy the passivation film and to passivation. General 18-8 stainless steel tube is very difficult to meet the use requirements, the urea grade stainless steel tube increase the element for Ni, Cr, Mo, N in the original based on stainless steel (enhanced), through the improvement of smelting process, production process and control of solution temperature, to achieve the user standard production need.
Application (urea apparatus): washing tower, a stripping tower, a condenser tube, the high-voltage wire.
