Maintenance of double-layer oil tank head
Date: May 11, 2020
The head is a very important part of the double-layer oil tank. It is related to whether the pressure vessel can operate safely, so daily maintenance is very important. The following will teach you the daily maintenance of the double-layer oil tank head.
1. Don't put it in the open air to avoid rain and rain. When cleaning, use stainless steel hydrochloric acid to clean. After welding with the double-layer oil tank, clean the weld and surrounding residues. Also perform PT inspection and surface acid. wash. Note that the surface of the head should not be damaged during use, and the structure of the pressure vessel should be prevented from being too large to avoid forced solder resistance.
2. When welding between the double-layer oil tank and the tank body, the debris in the welding seam and the heat affected zone must be cleaned up, and the surface of the head can be thoroughly pickled. The head of the oil tank It must also be protected in place and not damaged.
3. Do not store the stainless steel elliptical heads in the open air, and there should be no rain, or there must be no forced phenomenon when performing solder resistance.
The above is to explain the daily maintenance of the double-layer oil tank head, so we must maintain the maintenance work in order to extend the life of the oil tank head, and will not affect normal work.
