(Specification)Standard Specification for Machine Made “Fiberglass” (Glass-Fiber-Reinforced Thermosetting Resin) Flanges
Standard Specification for Machine Made “Fiberglass” (Glass-Fiber-Reinforced Thermosetting Resin) Flanges
ABSTRACT
This specification deals with the testing and performance requirements of machine made "fiberglass" (glass-fiber-reinforced thermosetting resin) flanges, other than those that are contact-molded. Flanges may be produced integrally with a pipe or fitting, may be produced with a socket for adhesive bonding to a pipe or fitting, or may be of the type used in conjunction with either a metallic or nonmetallic backup ring. Flanges are defined by type (method of manufacture), grade (generic type of resin), class (configuration of joining system), and pressure rating. Flanges are also given numerical classifications relating to rupture pressure, sealing test pressure, and bolt torque limit. Included are requirements for materials, workmanship, performance, and dimensions.
SCOPE
1.1 This specification covers reinforced-thermosetting resin flanges other than contact-molded flanges. Included are requirements for materials, workmanship, performance, and dimensions.
1.2 Flanges may be produced integrally with a pipe or fitting, may be produced with a socket for adhesive bonding to a pipe or fitting, or may be of the type used in conjunction with either a metallic or nonmetallic backup ring.
1.3 The values stated in inch-pound units are to be regarded as the standard. The values in parentheses are given for information only. In cases where materials, products, or equipment are available only in SI units, inch-pound units are omitted.
1.4 The following precautionary caveat pertains only to the test methods portion, Section 10, 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.
Note 1—Contact molded flanges are covered in Specification D5421 and referenced in Specification D5685.
Note 2—There is no known ISO equivalent to this standard.
