Active Standard ASTM D7602 | Developed by Subcommittee: D33.09
Book of Standards Volume: 06.02
Significance and Use
The storage of corrosive or abrasive solutions or suspensions requires that the metal surface of storage tanks, large pipes, or holding vessels be lined with a material that resists such action. Vulcanized rubber that is securely adhered to the tank or other metal surface imparts such resistance. An integral part of the installation of such linings is the vulcanization operation that produces proper mechanical strength, chemical resistance, and sufficient rubber-to-metal adhesion.
Service conditions will dictate what type of rubber is used. Also, the service conditions will determine the proper thickness of the rubber and the particular compound or compounds used in a lining. For example: temperatures over 140°F (60°C) typically require a thickness of ¼ in. (6.35 mm). Some service conditions that have a solution composed of several chemicals may require different layers of rubber compounds. Within these layers, the hardness or durometer of the rubber may be changed as well to provide the longest service life of the rubber lining. Consult with the rubber lining manufacturer when selecting the rubber lining system and preparing application specifications and procedures.
1.1 This practice covers the techniques used to install rubber lining sheet stock in metal tanks, pipes, and other components. Installation requirements, procedures, inspection instructions, and storage conditions for the lined tanks or equipment are outlined.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. This standard may involve hazardous materials, operations, and equipment.
