No ASME container manufactured on or after November 1, 1994, shall be used in the State of Texas unless it has attached to it a stainless steel manufacturer's nameplate. The nameplate shall be attached in a manner that will minimize corrosion of the nameplate or its attachments or that will not contribute to the corrosion of the container.

   1. (1) the mark or symbol approved by ASME indicating compliance with the provisions of the ASME Pressure Vessel Code;
   2. (2) the name and address of the manufacturer;
   3. (3) the capacity of the container in standard cubic feet;
   4. (4) the maximum allowable working pressure of the container in pounds per square inch (psi);
   5. (5) the wording "This container shall not contain a product having a vapor pressure in excess of _____ pounds per square inch at a temperature of 100 degrees Fahrenheit;
   6. (6) the thickness of the material used in both the shell and heads;
   7. (7) the overall length of the container, the outside diameter of the container, and the dish radius of the heads;
   8. (8) the serial number of the container; and

   1. (1) name of the container manufacturer;
   2. (2) manufacturer's serial number;
   3. (3) working pressure; and
   4. (4) water capacity.
