Abstract
This specification covers the design, construction, testing and operating requirements for pressure-reducing manifolds for air or nitrogen systems, which constitute the combination of all components and piping between, and including, the inlet and outlet ports. The manufactured manifolds shall perform satisfactorily to the following procedures: visual examination; hydrostatic shell test; relief-valve lift test; seat tightness test; and external leakage test.
Scope
1.1 This specification covers the design, construction, testing and operating requirements for pressure-reducing manifolds for air or nitrogen systems, referred to herein also as manifolds. The term manifold constitutes the combination of all components and piping between, and including, the inlet and outlet ports (see Fig. 1 and Fig. 2).
