The most common problems with stainless steel flanges

- Apr 08, 2018-

Modern industrial automation is becoming more and more popular. The production and manufacture of products are all produced automatically by mechanical equipment. Therefore, the working strength of the mechanical equipment itself is very large. In the long-term high-strength operation, the mechanical equipment used is prone to various problems. In some mechanical equipment, the stainless steel flange is an important part because the flange is played in this equipment. The role of some mechanical parts is fixed, but in continuous use, it will inevitably lead to a series of problems. Therefore, during the operation of the equipment, the operating parts of the equipment should be regularly checked and maintained in order to achieve a good and stable working performance.


The most common problem during the use of stainless steel flanges is when welding, it is easy to have deviations in size. Because at the time of welding, the generated high temperature will cause some changes to the metallographic structure of the flange itself, and at the same time, the thermal stress will cause the flange to deform locally, which will have a great influence on the use. If the stress on the heat affected zone at the welding site and the metallurgical structure are not recovered, the device will be vulnerable to embrittlement or corrosion during long-term operation. If the discharge is not discovered in time, the safety hazard will be very serious during the operation.
During the installation and use of the stainless steel flange, check whether there is any leakage or the like at the flange joint at any time. If there is a leak, check to see if the connecting bolt is loose. If there is still leakage after excluding this factor, replace the flange gasket or filter it.
