4 Fittings and Pipework
4.1 For rigid pipework systems solid drawn copper alloy or stainless steel tube should be used. Steel tubing, aluminium, or any materials having a low melting point should not be used.
4.2 Connection between rigid pipe sections should be made with, hard solder (minimum melting point 450°C). Appropriate compression or screwed fittings are recommended for general use for pipework in LPG installations.
4.3 Lengths of flexible piping (if required for flexible connections) should conform to an appropriate standard, be kept as short as possible, and be protected from inadvertent damage. Such hose should be installed in such a manner to allow access for inspection along its length.
Proposals for a more extensive use of flexible piping (which conforms to an internationally recognised standard for its application) should be submitted to the Administration for approval on an individual basis.
