Stainless steel flanges
As one of the stainless steel flange suppliers in China, we have been used in the 36 flange production experience, which is a very well-known company in China. We are a member of PetroChina and Sinopec, and participate in various government projects at home and abroad. Stainless steel non-standard flange in the pipeline engineering, the most common use, stainless steel flange is used in pairs, in the pipeline engineering, flange is the main pipe for the interface, in the demand of the pipeline, a variety of devices, a flange, low pressure pipe can use wire flange, more than 4 kg pressure of the use of welding flange, two pieces of flange between the sealing point, and then with bolts fastening, different pressure flange has a strange thickness and the use of strange bolts, pumps and valves, in and pipeline connection, these device equipment parts, also made corresponding flange shape, also known as flange connection.
Stainless Steel Flange Comprehensive performance:
As one of the of China stainless steel flange suppliers, our first concern is the quality of raw materials.The stainless steel flange has good metal performance, and has a strong corrosion resistance, is often used in steel structures, stainless steel flange also become rust-resistant steel flange, its metal surface is smooth, not easily with the air oxidation, so often used in high-pressure water pipes and corrosion of pressure piping,
Here and you share under the excellent performance of stainless steel flange. The corrosion resistance of stainless steels decreases with the increase of carbon content, therefore, most of the carbon content of stainless steel is lower, the largest is not more than 1.2%, some steel WC (carbon content) or even less than 0.03% (such as 00cr12), stainless steel, the main alloy element is CR (CR), only when the CR Flange factory content reached a certain value, steel corrosion resistance, therefore, stainless steel general CR (CR) content of at least 10.5%, stainless steel also contains NI,TI,MN,N,NB,MO,SI,CU elements such as stainless steel production of flange fittings called stainless steel flange.
Advantages of stainless steel flange:
As one of the of China stainless steel flange suppliers, We must improve the advantages of products in the production process in strict accordance with the ISO and international standards.
First of all, as a metal material in the humid environment will react with the air, so as to change the original metal properties, but the stainless steel flange can be deactivated with the oxidant, the surface formation of a strong and dense chromium-rich oxide protective film Cr2O3, stainless steel flange effectively prevent oxidation reaction of further occurrence, and other metal pipes, such as galvanized water pipes, copper tube passivation capacity is very small, this is galvanized pipe copper tube corrosion resistance is far less than the key reasons for stainless steel tubing.
Then the stainless steel flange corrosion resistance performance, stainless steel flange will not be the same as carbon steel corrosion, no need to protect the coating, stainless steel flange using stainless steel flanged water pipe, the chemical composition of the water is not limited, because stainless steel in a variety of oxygen content, temperature, ph and hardness of the water are very good corrosion resistance, Stainless steel pipe can withstand very high flow rate, even if the flow rate is greater than 40 m/s, still maintain a very low corrosion rate, no more than 0.003 mm/year, particularly suitable for high-rise water supply, stainless steel flange tube thermal expansion coefficient and copper tube similar, is 1.5 times times the ordinary steel pipe, stainless steel flange in contrast to stainless steel flange fittings have a slow expansion and contraction characteristics.
In addition, stainless steel flange general chemical reaction is integral, will form a layer of protective film on its surface, this is other metals can not do.
