conventional number or trademark of the manufacturer;

tank designation;

tank number according to the manufacturer’s numbering system;

year and month of manufacture.

In addition, the following must be stamped on the shell fitting: the tank number, the year and month of manufacture and the reference number or trademark of the manufacturer.

Upon customer request, other data may be indicated on tanks with a design pressure of 1.0 MPa (10 kgf/cm2).

5.2. After hydraulic tests, tanks must be dried inside, the openings of the fittings must be coated with anti-corrosion lubricant and plugged with a plug to prevent it from getting inside.

5.3. Group of tank storage conditions - C according to GOST 15150-69.

5.4. During transportation, tanks must be protected from shock and mechanical damage.

6. MANUFACTURER WARRANTY

6.1. The manufacturer must ensure that the tanks comply with the requirements of this standard, provided that the consumer complies with the rules of operation, transportation and storage.

The warranty period is 5 years from the date of commissioning of the tank.
