Manifold

Manifold (eng.Moldold, from many - many and fold - fold, fold) valve block - an element of oil and gas fittings , which consists of several pipelines , usually fixed on one base, designed for high pressure , and connected according to a certain pattern, and equipped with the necessary shut-off , other fittings , SR drill sleeves with a "triplicative crimping method" and expansion joints. Manifolds include throttling and jamming lines, which are structurally made in the form of blocks connected to the OP preventer block by trunk lines.

Typical schemes establish the minimum number of necessary components of the manifold, which can be supplemented depending on the specific conditions of the well being under construction or under repair.

Manifolds are used to redistribute or mix a gas or liquid flow between one or more inlets and one or more outlets. They are also used to connect differential pressure gauges and other instrumentation to process equipment and trunk pipelines. The manifold is part of blowout control equipment ^[1] at the sites of oil and natural gas production.

The manifold designation system consists of letters indicating the design of the manifold and two numbers, the first of which indicates the conditional passage of the manifold in arbitrary units (not to be confused with the diameter of the pipe), and the second is the calculated working pressure in atmospheres or megapascals (MPa).
