How to inspect and identify carbon steel rubber-lined equipment? Lined with PO.
How to inspect carbon steel rubber-lined equipment, ----------------------------------------------- -------------------------------------------------- Use electric spark inspection
First of all, check the appearance with the naked eye. There should be no wrinkles or blisters. Each seam should be welded tightly. Then perform electric spark inspection according to HGJ229 regulations.
Electric spark inspection is used, but mainly visual inspection, according to industry standards. We recently made a carbon steel container lined with rubber. There were no problems with the spark detection, but there were bulges.
Everything is correct, but the order is a bit confusing. 1. You should check visually first. If the visual inspection fails, there is no need to proceed to the next step of inspection. 2. After visual inspection, conduct final spark inspection. This item is the most important basis for acceptance.
PO lining cannot be called rubber lining. It should be called plastic lining. Glue refers to rubber.
The 5th floor is right. One more thing to add is that the final leak test or water pressure test should be done with water.
