Standard Specification for Chemical-Resistant Ceramic Tower Packings

Fecha:
2018-05-16 /Active
Abstract:

This specification covers fired chemical-resistant ceramic tower installation packings formed from naturally occurring clays or compounded bodies. The number of dumped pieces of cylindrical-type packing material should conform to the requirements for each ring, packing, and saddle size. Material properties such as crushing strength, water absorption, and acid resistance should also fall within the given values for both porcelain and stoneware packings.

Scope:

1.1 This specification covers fired ceramic shapes formed from naturally occurring clays and from compounded bodies that are used as packing in tower installations. These ceramic units are designed primarily for use in process equipment for the chemical or allied industries.

1.2 The physical and chemical properties that affect quality of packing materials are covered in this specification. Properties that affect actual operational efficiency or characteristics of processing towers are not covered.

1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.

1.4 The following precautionary statement pertains to the test method portion only, Section 7, of this standard. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
