(Specification)Standard Specification for Performance of Piping and Tubing Mechanically Attached Fittings
Standard Specification for Performance of Piping and Tubing Mechanically Attached Fittings
ABSTRACT
This specification establishes the performance characteristics required for mechanically attached fittings (MAFs) for use in piping and tubing systems. 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. process. MAFs covered here are classified into the following design types: Type I—radially swaged MAF (permanent); Type II—flared MAF (separable); Type III—flareless (bite-type) MAF (separable); Type IV—grip-type MAF (separable); Type V—shape memory alloy (SMA) MAF (permanent); and Type VI—axially swaged MAF (permanent). Moreover, the MAFs shall be made from on or more of the following material grade: Grade A—carbon steel; Grade B—stainless steel; Grade C—nickel-copper; Grade D—copper-nickel; Grade E—brass; and Grade F—nickel titanium. The MAFs shall also be grouped into ten classes according to their pressure ratings. The standard qualification tests to which the MAFs shall perform satisfactorily are pneumatic proof test, hydrostatic proof test, impulse test, flexure fatigue test, tensile test, hydrostatic burst test, repeated assembly test, rotary flexure test, and mercurous nitrate test. Successful completion of the tests described constitutes completion of the technical portion of the qualification
SCOPE
1.1 This specification establishes the performance characteristics required for mechanically attached fittings (MAFs) for use in piping and tubing systems. 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 or created independently. Successful completion of the tests described constitutes completion of the technical portion of the qualification process.
1.2 Supplementary requirements are provided for use when additional testing or inspection is desired. These shall apply only when specified in part or whole by the purchaser in the order. Unless otherwise specified, U.S. Navy contracts shall invoke the supplementary requirements in whole.
1.3 Unless specific MAF types are specified, the term “MAF” shall apply to all types described herein.
1.4 The tests specified in Section 13 and described in Annex A1 and Supplementary Requirements are applicable only to ascertain the performance characteristics of MAFs. These tests are not intended for use in the evaluation of non-MAF products.
1.5 A fire performance test is specified in Supplementary Requirement S7. This test provides general guidelines to determine the responsiveness of MAFs when subjected to fire. This test should not be considered for use to evaluate non-MAF products.
1.6 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.7 The following safety hazards caveat applies only to the tests listed in Section 13 and the tests described in the Supplementary Section and the Annex 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.
