ASTM F1122-04(R2021) pdf free download.Standard Specification for Quick Disconnect Couplings (6 in. NPS and Smaller)
1. Scope
1.1 This specification covers the manufacturing data re- quired to produce a variety of styles and sizes of quick disconnect couplings up to and including NPS 6 for marine use that ensure interchangeability and safety of operation. 1.2 In general, quick disconnect couplings are hose and pipe end fittings that permit quick mechanical attachment by means other than bolted or threaded fittings. The method of attach- ment is a male coupling half (adapter) that fits into a female coupling half (coupler) of the same size. By closing attached cam handles, the coupling halves seal, permitting fluids to be transported under pressure through the quick disconnect cou- pling. 1.3 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. 1.4 The following safety hazards caveat pertains only to the test method described in this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility ofthe user ofthis standard to establish appropriate safety, health, and environ- mental practices and determine the applicability ofregulatory limitations prior to use. 1.5 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
3. Terminology
3.1 Definitions ofTerms Specific to This Standard: 3.1.1 adapter, n—one half of a quick disconnect coupling that fits into the coupler and seals against an elastomer gasket positioned inside the coupler. 3.1.2 cam handles, n—handles that are assembled to the coupler half which by closing engages the adapter sealing the coupling. 3.1.3 coupler, n—one half of a quick disconnect coupling that receives the adapter. This half contains the sealing gasket and cam handles (see Fig. 1). Discussion—See Fig. 2 for a description of typical coupler pipe fittings.
4. Classification
4.1 Quick disconnect couplings shall consist of the follow- ing types: 4.1.1 Standard Class—This type is to be designed for a 4:1 burst factor of safety. 4.1.2 Class I—This type is to be designed for a 5:1 burst factor of safety.
5. Ordering Information
5.1 Purchase orders for quick disconnect couplings under this specification shall include the following applicable infor- mation: 5.1.1 Class. 5.1.2 Size and type of each coupling half-end connection. (Example: 2- by 1 1 ⁄ 2 -in. NPT.) 5.1.3 ASTM material designation and date including alloy specifications for the following: Adapter and coupler halves, Cam handle, and Cam handle pivot pin. 5.1.4 Product or fluid in applicable system. 5.1.5 Shipping instructions. 5.1.6 Any special requirements, such as testing, coatings, and threads. 6. Materials and Manufacture 6.1 Materials: 6.1.1 Pressure-retaining parts shall be manufactured from material specifications and grades listed in Section VIII, Division 1, of the ASME Boiler and Pressure Vessel Code or ASME B31.1. 6.1.2 All other materials of construction shall be of the type specified by the user and shall conform to ASTM, ASME, or Metal Power Industry Federation material specifications. Ma- terials not identified by the ordering data shall be of the manufacturer’s standard and of the same quality used for the intended purpose in commercial practice. 6.1.3 All material incorporated in the work covered by this specification shall be new. The use of rebuilt or used products are not allowed under this specification. 6.1.4 Gaskets are to be produced from a compressible elastomeric material and shall be compatible with the fluid to be transferred (see 5.1.4). 6.2 Manufacture: 6.2.1 Adapters and couplers are to be produced as castings or forgings. Cam handles may be produced by casting, forging, or sintered metal processes. Established commercial process- ing methods are to be used to produce these parts, provided chemical and physical properties are consistent with those cataloged for the specified materials. 6.2.2 Pipe threads on the service end of couplers or adapters, when specified, shall meet ASME/ANSI B2.1. 6.2.3 Flanges on the service end of couplers or adapters, when specified, shall meet ASME B16.5, B16.24, or B16.
