Abstract

This specification establishes the material, manufacturing, performance, and testing requirements for Metallic Press-Connect Fittings used in piping and tubing systems with a maximum allowable working pressure of 300 psi. Metallic Press-Connect Fittings are directly attached to pipe or tube by mechanical deformation of the pipe or tube or fitting, or a combination thereof, creating a seal and a restrained joint. The seal may be created via the mechanical deformation (of the pipe, tube or fitting) or created independently. Press-Connect fittings shall be made from one or more of the following material grades: Grade A (carbon steel), Grade B (stainless steel), Grade C (copper and copper-alloy), Grade D (copper-nickel), and Grade E (brass). The fittings rated pressure shall be one of the following classes: Class 1 (100 psi [0.69 MPa] maximum), Class 2 (200 psi [1.38 MPa] maximum), and Class 3 (300 psi [2.07 MPa] maximum). The elastomeric seals are of three types: Type 1 (ethylene propylene diene monomer [EPDM]), Type 2 (hydrogenated nitrile butadiene rubber [HNBR], and Type 3 (fluoro-elastomer or synthetic fluorinated rubber [FKM]).

This specification also covers ordering information, dimensions, and workmanship, finish, and appearance, as well as sampling for testing, tests and re-tests, specimen preparation, inspection, certification, and product marking.

Scope

1.1 This specification establishes the performance characteristics required for Metallic Press-Connect Fittings for use in piping and tubing systems with a maximum allowable working pressure of three-hundred pounds per square inch (300 psi) [2.07 MPa]. These fittings directly attach to pipe or tube by mechanical deformation of the pipe or tube or fitting, or a combination thereof, creating a seal and a restrained joint. The seal may be created via the mechanical deformation (of the pipe, tube or fitting) or created independently. Successful completion of the tests described herein constitutes completion of the technical portion of the qualification process.

1.2 The tests specified are applicable only to ascertain the performance characteristics. These tests are not intended for use in the evaluation of non-Press-Connect Fittings.

1.3 Refer to IACS UR P2.7.4, Table-7 for Metallic Press-Connect Fittings applications.

1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

1.5 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.

1.6 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.
