AISI Cold Drawn Stainless Steel Coil Tubing For Chemical Industry
Because the stainless steel heat exchange coil has very outstanding rust prevention, anti scaling and ety and health characteristics, and the heat transfer performance has reached the copper level, and the service life is longer than the copper pipe, more cost-effective.Therefore, stainless steel heat exchanger has been widely used in many fields at present.For example, medicine, boiler, heating, domestic water, air conditioning and other fields are involved.
According to the data of heat exchange equipment promotion center, the stainless steel heat exchanger has better heat transfer effect than the traditional carbon steel heat exchanger, and the service life is longer;Now the heat exchanger is generally used 304, 316, 316L, 321, 310S stainless steel material, different application areas will also choose different materials of stainless steel according to its performance requirements for heat exchanger.
1, the heat exchanger of food machinery and equipment should meet the ety and health standards, mostly 316 or 316L stainless steel heat exchange coil, and the polishing, cleanliness and corrosion resistance of the pipe fittings have strict requirements, after all, is in contact with food.
2, the life of the solar water tank, water heater and other general use of 304 stainless steel coil, required to be able to withstand the temperature of daily living water, oxidation resistance and anti-scaling.
3, boiler generally use 310S stainless steel heat exchange coil, this is a kind of austenitic chromium nickel stainless steel, has good oxidation resistance, corrosion resistance and high temperature resistance;Due to the high percentage of chromium and nickel, it has good multi-creep strength, can continue to work at high temperature, the maximum temperature resistance of 1200 ℃.
