The reason why stainless steel flange products have a wide range of applications?
The reasons for the wide range of applications of stainless steel flange products? When stainless steel flange fittings are welded, carbides are repeatedly precipitated to reduce corrosion resistance and mechanical properties. The use of a wide range of products has now been applied in many industries. Nowadays, with the development of technology, products have been greatly improved in performance. At present, many manufacturers produce sub-products, in order to use more safe and secure, must read the relevant instructions before use.
Some notes on the use of stainless steel flanges:
1. In order to prevent the eye-catching corrosion caused by the heating of the flange cover, the stainless steel flange welding current should not be too large, about 20% less than the carbon steel electrode, the arc should not be too long, fast cooling between layers, with a narrow bead is appropriate .
2. When the electrode is used, it should be kept dry. The titanium-calcium type should be dried at 150°C for 1 hour. The low-a hydrogen form should be dried at 200-250°C for 1 hour (cannot be repeatedly dried, otherwise the coating will be easily cracked and peeled off). The electrode sticks stick oil and other dirt so as not to increase the carbon content of the weld and affect the quality of the weldment.
Tips: The purchase of stainless steel flange products can not rely solely on prices, but to refer to many factors, such as the qualification of the manufacturer, the raw materials of the products, etc. Today's products can not be the same, it is used by many industries. However, it does not mean that it can be simply operated during installation and use, but it should also be conducted in accordance with the formal instructions!
