How to improve the service life of anti-overflow baffles in high-pressure flash tanks? I would appreciate any insights you all might have; could you share some advice?
What is commonly seen is the addition of a layer of wear-resistant material at the bottom
Cladding using welding electrodes of different materials
The angle valve leading to the high flash point vessel was changed from a horizontal installation to a vertical one; a wear-resistant bypass was installed behind the angle valve so that the black water, after being depressurized by the angle valve, does not directly impact the internal components of the high flash point vessel. Our company has renovated 2 of them, and the results have been good.
In this method, the internal scouring is replaced by external scouring; the scouring does not decrease, only its location changes. But modifying it in high-pressure areas is somewhat pointless. The high-flash impact shield is perforated and worn; it is recommended to use nickel-based corrosion-resistant alloy sheets to divert the black water over the distance until it reaches the impact shield. The specific measures are just my idea.
External flushing should be better; for investment casting permits, use tungsten carbide lining
I chose the surfacing method combined with the use of steel rods as impact barriers; the results are still under evaluation, with the hope of extending the service life.
The length of the buffer tank can be appropriately increased to concentrate the water flow impact at the upper part, thereby reducing the pressure on the blocking plate; the bottom section can be made thicker using manganese steel
