As we all know, the electric ball valve is the first valve ball and flange. Then the flange is divided into carbon steel Q235A (forged) appearance plastic antirust paint, 304 stainless steel, 316L stainless steel, PVC data. According to the market survey results of Songjiang Sales Department, carbon steel flanges are widely used in electric ball valves. Therefore, what are the main functions of carbon steel flanges in electric ball valves?
1. Good thermal insulation: due to the low data thermal conductivity of butt welded carbon steel flanges, the thermal conductivity at 20 ℃ is 0.21-0.24W/mk, which is far less than steel pipes and purple steel pipes, so pp - r pipes have good thermal insulation.
2. High impact resistance: due to the joint impact strength of butt welded carbon steel flanges, compared with other solid wall pipes, its ring stiffness is 1.3 times that of solid wall pipes.
3. Good corrosion resistance: In addition to a few hydrogenation agents, it can withstand the corrosion of various chemical media. Carbon steel welding flange has excellent acid resistance, alkali resistance, corrosion resistance, no rust, no corrosion, no bacteria breeding, no electrochemical corrosion.
4. Long service life: carbon steel butt welded flange pipe can be used for more than 50 years under additional working temperature and pressure, with ultraviolet protection and radiation protection functions, so that the goods will never fade. It is used for the excellent induction function of carbon steel flange of electric ball valve. First, it is used for coal fired power plants, metallurgy industry, condensate, professional chemical pipeline transportation, raw water and sewage of petrochemical industry, and lifting and transportation of water supply and cooling circulating water. Flexible connection between cooling, dilution and other disciplines and pipe lengths. Due to its high wear resistance, the valve is also suitable for all occupational particles and powders as well as low-temperature steam transportation.
