Pipelines<br />
4.—(1) Every pipelineshall be fixed in such a manner <strong>and</strong> position that—<br />
(a) it willnot be adversely affected by the heat of the exhaust system of any engineor any other<br />
source of heat,<br />
(b) it is protectedfrom vibration <strong>and</strong> strain in excess of that which it can reasonably be<br />
expectedto withst<strong>and</strong>, <strong>and</strong><br />
(c) in thecase of a high pressure pipeline it is so far as is practicable accessiblefor inspection.<br />
(2) Save as providedin sub-paragraph (4) below, every high pressure pipeline shall be—<br />
(a) a rigidline of steel, copper or copper alloy of high pressure hydraulic grade, suitablefor<br />
service on road vehicles <strong>and</strong> designed for a minimum service pressure ratingof not less<br />
than 75 bar absolute, <strong>and</strong><br />
(b) effectivelyprotected against, or shielded from, or treated so as to be resistant to,external<br />
corrosion throughout its length unless it is made from material whichis corrosion resistant<br />
under the conditions which it is likely to encounterin service.<br />
(3) No unsupportedlength of any high pressure pipeline shall exceed 600 mm.<br />
(4) Flexible hosemay be used in a high pressure pipeline if—<br />
(a) it is reinforcedeither by stainless steel wire braid or by textile braid,<br />
(b) its lengthdoes not exceed 500 mm, <strong>and</strong><br />
(c) save inthe case of a pipeline attached to a gas container for the purpose of fillingthat<br />
container the flexibility which it provides is necessary for the constructionor operation of<br />
the gas system of which it forms a part.<br />
(5) If a high pressurepipeline or part of such a pipeline is so constructed or located that it may,in<br />
the course of its normal use (excluding the supply of fuel from a gas container),contain liquid which<br />
is prevented from flowing, a relief valve shall be incorporatedin that pipeline.<br />
Unions <strong>and</strong> joints<br />
5.—(1) Every union<strong>and</strong> joint on a pipeline or gas container shall be so constructed <strong>and</strong> fittedthat<br />
it will—<br />
(a) not beliable to work loose or leak when in use, <strong>and</strong><br />
(b) be readilyaccessible for inspection <strong>and</strong> maintenance.<br />
(2) Every unionon a high pressure pipeline or on a gas container shall be made of suitablemetal<br />
but such a union may contain non-metal washers <strong>and</strong> seals provided thatsuch washers <strong>and</strong> seals are<br />
supported <strong>and</strong> constrained by metal components.<br />
Reducing valves<br />
6. Every reducing valve shall be made of suitablematerials <strong>and</strong> be so fitted as to be readily<br />
accessible for inspection <strong>and</strong>maintenance.<br />
Pressure relief valves<br />
7.—(1) Every pressurerelief valve which is fitted to any part of a gas system (including a<br />
gascontainer) shall—<br />
