For lined equipment/catalyst pipelines in the two-tank system of catalytic units, after new openings are made, is it necessary to redo the lining around those openings? What is the area involved, and are there any standards?
Large pores need to be reinforced again, while small pores do not.
Are there any standard requirements for specific dimensions?
After making the hole, knock off the damaged lining around it; if the area is large, weld in anchor bolts or mesh panels, and then apply the lining.
Are there any standards? At that time, one of our lined tanks had holes made in it after installation, and the lining was not repaired that time.
