Is the external corrosion protection of flange forgings important?
The integrity of the flange forging connection is the key to the fluid piping system. Whether it is a piping system used to transport chemical media such as hydrocarbons, or a water supply pipe, leaks on flanged forging connections can have serious environmental and economic impacts and can even pose a major safety hazard. If the flange forgings are not protected and exposed to corrosive environments or industrial air pollution, the corrosion rate will be faster.Due to the complex geometry of the flange forging connection, gap corrosion between flange surfaces and galvanic corrosion between metals are prone to occur, which seriously damages the integrity of the pipeline system. This article introduces the external anti-corrosion method of flange forgings. importance.
Effective monitoring and detection is necessary to meet high production demands and reduce sudden shutdowns due to leaks. Generally, technicians only pay attention to the leakage between the flange faces, but ignore the protection of fasteners and the outside of the pipeline. In the harsh external environment, the consequences may be very serious. Insufficient external protection will accelerate the damage of flange forgings and fasteners, and accelerate the deterioration of the entire sealing system, which will quickly destroy the structural integrity of the system and cause seal failure.
Because the visual inspection of the flange forging connection seal can only be carried out when the whole system is out of operation, the inspection procedure should be as simple as possible, so the external corrosion should be eliminated first. If the operation cannot be stopped, ultrasonic technology can only be used for detection. If the external corrosion cannot be controlled, the detection process will be more complicated and accurate detection results cannot be obtained. Therefore, the external corrosion protection of flange forgings and fasteners is the key to monitoring the entire system and providing effective and feasible quality control and maintenance procedures.
