Standard Specification for Tools to Squeeze-off Polyethylene (PE) Gas Pipe or Tubing
|Publication Date:||1 August 2011|
|ICS Code (Plastics pipes):||23.040.20|
1.1 This specification covers the physical requirements for tools used to squeeze-off polyethylene (PE) pipe and tubing. It is limited to squeeze-off procedures set forth by the pipe manufacturer as referred to in Specification D2513 for gas pressure pipe systems.
1.2 Nothing in this specification shall be construed as recommending practices or systems at variances with governing codes and project specifications.
1.3 Where applicable in this specification, "pipe" shall mean "pipe and tubing," and "tool" shall mean "squeeze-off tool."
1.4 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.
1.5 The following safety hazards caveat pertains only to the test methods portions, Section 5 and Appendix X1 of this specification: 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 specification covers the physical requirements for tools used to squeeze-off polyethylene gas pipe and tubing. The squeeze bars shall be of a size and configuration that compresses the pipe walls to reduce the gas flow, but does not damage the pipe and may be configured as round (circular), flat with rounded edges, two round bars side by side, or any other configuration. The tool shall have the following requirements: mechanical, hydraulic, or pneumatic force mechanisms; resistance to damage or deformation; release protection; release rate; flow control; and grounding. It shall also have sufficient squeeze bar length and spacing to allow the maximum diameter pipe to be centered between the guides and mechanical stops to provide protection for over squeezing.View Less
