KXT low-temperature flexural rubber joints welding method
KXT low temperature flexible rubber joints that accept fluid pressure are subjected to hydraulic tests to check their pressure resistance and quality, and are qualified for no leakage, wetting or swelling under the rule pressure. KXT low-temperature bendable rubber joints that accept fluid pressure are subjected to hydraulic tests to check their pressure resistance and quality, and are qualified if they do not leak, wet or swell under the rule pressure, and some KXT low-temperature bendable rubber joints are also subjected to edge-rolling tests, flaring tests, flattening tests, etc. according to specifications or requirements of the demand side.
KXT low-temperature flexural rubber joints can use paint or oxidation-resistant metals (for example, zinc, nickel and chromium) for plating to ensure the appearance of carbon KXT low-temperature flexural rubber joints, but, as is well known, this maintenance is only a thin film. If the maintenance layer is damaged, the following KXT low temperature flexible rubber joint will begin to rust and corrosion, resistance to weak corrosive media such as air, steam, water and acid, alkali, salt and other chemically leaching corrosive media KXT low temperature flexible rubber joint. one of the advantages of KXT low temperature flexible rubber joint material is its excellent corrosion resistance, in a variety of pipe is.
Because KXT low-temperature resistant bendable rubber joints can be passivated with oxidizing agents, a layer of tough and dense chromium-rich oxide maintenance film Dr2O3 is formed on the exterior, which is useful for blocking further oxidation reactions. And other metal pipes, such as galvanized water pipes, copper pipes passivation ability is very small, which is the KXT low-temperature flexible rubber joint of copper pipe corrosion resistance is far less than the KXT low-temperature flexible rubber joint material the key reason.
KXT low temperature bendable rubber joints will not be like carbon KXT low temperature bendable rubber joints as the onset of uniform corrosion, the use of no maintenance coating; choose KXT low temperature bendable rubber joints water pipe, the chemical composition of the water is not bound, because KXT low temperature bendable rubber joints in a variety of oxygen content, temperature, PH and hardness of the water have very good corrosion resistance; KXT low temperature bendable Rubber joint water pipe can satiate a very high flow rate, even if the flow rate is greater than 40 m / s, still adhere to the low corrosion rate, not more than 0.003 mm / year, especially suitable for building water supply.
KXT low temperature flexible rubber joint material lifting, can not be directly touched with other metals, should be padded with non-metallic materials such as wood or rubber sheet. kxt low temperature flexible rubber joint requires deep welding penetration, no oxide adulteration, heat-affected zone as small as possible, tungsten inert gas maintenance of argon arc welding has good adaptability, high welding quality, good weld penetration performance, its products in the chemical, nuclear and food industries, etc. industries are widely used.
