Duplex Stainless Steel Pipe Fittings S22053 S25073 S22253 S31803 S32205 S32304
What are the advantages of duplex steel?
1. The yield strength is more than double that of the commonly used 316L 308 stainless steel. And has sufficient plastic toughness required for molding. The wall thickness of the storage tank or pressure vessel made of duplex stainless steel is 30-50% less than that of the commonly used 316L, which is conducive to reducing costs.
2. Has excellent resistance to stress corrosion cracking. Even the least alloyed duplex stainless steel has higher resistance to stress corrosion cracking than austenitic stainless steel, especially in the environment containing chloride ions. Stress corrosion is a prominent problem that ordinary austenitic stainless steel is difficult to solve.
3. The corrosion resistance of 2205 duplex stainless steel, which is the most common application in many media, is better than that of ordinary 316L austenitic stainless steel, while super duplex stainless steel has extremely high corrosion resistance and fatigue resistance.

Why choose us:
1. All pipe fittings are strictly implemented in accordance with the standards, accept any third-party inspection, and return service.
2. Before leaving the factory, 100% dimensional inspection, 100% spectral test, mechanical and mechanical performance test, pickling, pickling process are mainly aimed at the removal of surface grease and harmful substances, complete surface passivation to prevent oxidation. Some suppliers have not implemented ( Because the surface is not visible to the naked eye after sandblasting) annealing and solid solution (heat treatment), many goods on the market are not heat-treated. When the pipe fittings are in some cold or hot environments, the seam will slowly crack if it is not heat-treated. This process is invisible to the naked eye, surface sanding (many relatively inexpensive processes on the market), bevel ends, etc.
3. Normally, the individual weight of our company's pipe fittings is heavier than that on the market, (Ensure the back arc thickness) to avoid the parts of the same wall thickness that cannot be seen by the naked eye after the processing The pressure is guaranteed, because many suppliers choose the material to the maximum limit in order to minimize the cost.
