Good product you need to have good manufacturers to produce, manufacturers Hotline best domestic manufacturer of stainless steel stamping elbow of course, is the first Thai extension tube. Manufacturers have a good quality of the workforce and well-advanced equipment, elegant operating environment, improve the scientific management system is the pipe factor in our success, advanced production equipment, strong technical force, strict process control system and improve the service system for product quality to provide a strong guarantee. We wholeheartedly welcome the new old customers to visit the factory, inspected and negotiations guidance to welcome you to inquire stainless steel stamping elbow plant Tip: When welding stainless steel stamping elbow we generally pay attention to the following 8:01), because the heat is generated in order to prevent eye Room erosion, welding current should not be too, less than about 20% carbon steel electrode, the arc should not be too fast cooling between layers to narrow bead appropriate. 2) After welding stainless steel stamping elbow sclerosing large, easy to crack. If using the same type of stainless steel stamping elbow welding, must be slow cooling process after more than 300 ℃ preheating and soldering of about 700 ℃. If you can not weldment after weld heat treatment, welding rod should be made of stainless steel stamping elbow. 3), stainless steel stamping elbow, to improve corrosion resistance and weldability function appropriately increase the right amount of chaos of elements Ti, Nb, Mo, etc., welding resistance than stainless steel stamping elbow better. When using the same type of chromium stainless steel electrodes, it should be tempered after more than 200 ℃ preheating and soldering 800 ℃ or the. If the weldment is not heat-treated, chrome-nickel stainless steel welding rod should be used. 4), stainless steel stamping elbow electrode having good corrosion resistance and oxidation resistance, widely used in chemical, fertilizer, petroleum, medical machinery. 5), stainless steel stamping elbow skin with titanium calcium type and low hydrogen type. Titanium calcium type can be used for AC and DC, but AC weld penetration depth is shallow, at the same time easy to redness, so far as possible dc power supply. 6), stainless steel stamping elbow with a certain degree of corrosion (oxidation acids, organic acids, cavitation), heat and wear performance. Typically used in power plants, chemical, oil and other equipment and materials. Welded stainless steel stamping elbow poor, should pay attention to the welding process, heat treatment provided and the appropriate choice of welding. 7), should be kept dry electrodes using titanium calcium type should be dried to 150 ℃ 1 hour low hydrogen type should be dried 200-250 ℃ 1 h (not repeated drying, cracking or peeling skin easily), to prevent the electrode sticky skin oils and other dirt in order to avoid causing weld carbon content increases and the impact weldments quality. 8), stainless steel stamping elbow welding, subjected to repeated heating carbide precipitation, lower corrosion resistance and mechanical properties.
