标准简介

适用范围：

This practice provides a procedure for determining the temperature history of plastic gas pressure pipe encased in metallic casings.The data obtained are indicative of the temperature attainable within a service riser of a specific design and size in a given geographical location under the climatogical conditions in existence during the test period.The data obtained can be used within the constraints of 4.2 to design the maximum allowable operating pressures permitted by existing codes.1.1 This practice describes a procedure for the determination of the temperature history of above-ground plastic gas pressure pipe encased in a metallic casing. Such temperature changes may be due to ambient air temperature, or solar exposure, or both.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.
