Urea Grade Austenitic Seamless Stainless Steel Pipe
Urea-grade stainless steel is austenitic stainless steel specially developed for high-temperature carbamate solutions (such as urea production). Urea grade stainless steel has strong corrosion resistance in high-temperature carbamate solution. The environment is generated when ammonium carbamate is used as a medium for the reaction of ammonia and carbon dioxide in urea production. It has strong resistance to local corrosion generated in the high-temperature carbamate environment of the high-pressure part of the urea equipment. 2522 stainless steel has little weight loss and local corrosion in the Huey test. 725LN is a fully austenitic structure and has a low content of non-metallic impurities. It is mainly used in the manufacture of urea production equipment.

It is mainly used in the manufacture of urea production equipment.
This type of steel pipe is mainly used in the core components of synthetic ammonia and urea industry. The raw materials are obtained by electro-slag remelting.
In addition to focusing on cleanliness control in the production process, the focus is on the control of heat treatment links. They are all ultra-pure stainless steels, which mainly solve the problem of selective corrosion of ferrite in the ammonia environment during urea synthesis.
In addition to focusing on cleanliness control in the production process, the focus is on the control of heat treatment links. They are all ultra-pure stainless steels, which mainly solve the problem of selective corrosion of ferrite in the ammonia environment during urea synthesis.
Austenitic stainless steel pipe has a stable austenite group at room temperature. The steel contains about 18% Cr, more than 8% Ni, and about 0.1% C. It has high corrosion resistance, good cold processing, and good toughness, plasticity, welding, and non-magnetic properties. It is widely used in heat exchangers, non-magnetic condensers, evaporators, and fluid transportation in chemical, oil refining, boilers, food, and other industries.
Super austenitic stainless steel pipe has higher cleanliness, uniformity, mechanical properties, finer structure, better surface quality, better resistance to local corrosion of harsh media, and better process manufacturing performance than ordinary austenitic stainless steel pipe.
Super austenitic stainless steel pipe has higher cleanliness, uniformity, mechanical properties, finer structure, better surface quality, better resistance to local corrosion of harsh media, and better process manufacturing performance than ordinary austenitic stainless steel pipe.
It is a stainless steel developed for urea production based on 316L, with additional restrictions on the minimum content of Cr, Ni, and Mo; the purpose is to obtain a fully austenitic structure of stainless steel after the final heat treatment and to make the ferrite content not exceed 0.6%, and at the same time, requirements are put forward for intergranular corrosion tendency experiments and selective corrosion.
This material is specially used in the urea industry. Therefore, urea and 316l stainless steel are called. Urea and stainless steel need to undergo Hugh test and selective corrosion test.
