(Practice)Standard Practice for Determining Allowable Tensile Load for Polyamide-12 (PA12) Gas Pipe During Pull-In Installation
Standard Practice for Determining Allowable Tensile Load for Polyamide-12 (PA12) Gas Pipe During Pull-In Installation
SIGNIFICANCE AND USE
4.1 The ATL value is used to set the break-away strength of a weak-link device, or to set other equipment used to limit pulling force during pull-in installation of PA12 gas pipe, or to determine if pulling equipment can exert pulling force greater than the ATL value for the PA12 gas pipe being installed.
4.2 The ATL value is determined before gas pipe installation.
SCOPE
1.1 This practice provides a means to determine an allowable tensile load (ATL) value for a polyamide-12 (PA12) gas pipe that is to be installed underground using methods that pull the pipe into a trench (cut or plowed), bore hole, casing pipe, or the like. The ATL value takes into account pipe size, tensile yield strength, pipe temperature, and pulling load duration.
1.2 The ATL is used to set the break-away strength for a “weak-link” device, or as a limit setting for other devices that control the maximum pulling force exerted by equipment used to pull PA12 gas pipe into an underground location, or to determine if pulling equipment can exert pulling force greater than the ATL value for the gas pipe being installed. A weak-link device is installed where the pipe pulling equipment is connected to the PA12 gas pipe. If pulling load exceeds the ATL limit, the device de-couples the pipe from the pulling equipment. Other measures or equipment that limit the pulling force on the pipe are also used. When the ATL value is compared to the pulling force developed by the pull-in installation equipment, and the equipment cannot exert a pulling force greater than the ATL value, a weak-link or other device for limiting the pulling force is not necessary.
1.3 This practice does not address weak-link device design or requirements, nor does it address the design or requirements for other equipment or procedures used to limit the pulling force applied to PA12 gas pipe during pull-in installation.
1.4 This practice does not address installation methods or procedures employed for pull-in of PA12 gas pipe.
1.5 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.
1.6 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.
1.7 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.
