Description
ASTM A182 F316L flange ASTM A182 F316L Flat welded flange, stainless steel flange with excellent metal characteristics and performance. Commonly used in steel parts, such as stainless steel flanges. Stainless steel flanges also become stainless steel acid-resistant steel flanges. Its metal surface is smooth, and it is not easy to produce air oxidation with gas. Therefore, it is often used for high pressure water pipes and corrosion of working pressure pipes. Here we share with you the characteristics of stainless steel flanges. First, as a metal material, it will reflect the gas under wet and cold conditions, and then change the original metal properties. However, stainless steel flanges can passivate with oxides and produce a strong layer of high-density chromium-rich metal oxide protective film Cr2O3 in appearance. Stainless steel flanges prevent further REDOX reactions. Other metal pipes, such as hot-dip galvanized water pipes, the passivation capacity of air conditioning copper pipes is smaller, which is the core reason why the characteristics of galvanized steel pipe air conditioning copper pipes are much lower than stainless steel pipes.
ASTM A182 F316L Flange connection is to fix two pipes, pipes or equipment to a flange plate, in the middle of the two flange plates, with a flange pad, and tighten the ground bolt to complete the connection. Some pipes and equipment have built-in flange plates, which are also flange connections. Flange connection is the main interface mode of pipeline construction. Polygold welded flange is suitable for pipelines with large changes in working pressure or temperature or high temperature and high pressure pipelines, and is also used for transporting expensive, flammable, flammable and explosive materials. Welding flange is not easy to deformation, good sealing, pound PN in 16MPa.
The main feature of ASTM A182 F316L stainless steel flange is that stainless steel flange is not easy to produce symmetrical corrosion like carbon steel, and no maintenance coating is required during application; Stainless steel flange The selection of stainless steel flanged water pipes, there is no limit to the chemical composition of water. Stainless steel water pipes can withstand higher flow rates. Even if the flow rate exceeds 40 m/ s, the corrosion depth remains no more than 0.003mm/ year, especially suitable for high-rise building power supply. The expansion coefficient of the stainless steel flange pipe is similar to that of the air conditioning copper pipe, which is 1.5 times that of the carbon steel pipe. Compared with stainless steel flanges, stainless steel flanges have the characteristics of slow heat rise and slow contraction.
