2022年3月2日 · Mechanical fittings for use with polyethylene pipe in gas supply are manufactured to BS EN 1555-3 or GIS:PL3, as required. Where mechanical fittings (e.g. spigot end fittings / stub flanges) are connected to the polyethylene pipe by butt fusion, the spigot end is specified to GIS:PL2-6, see Butt Fusion section above.

This document provides the scope, normative references, and section 1 of a Gas Industry Standard specification for self-anchoring mechanical fittings for natural gas and suitable manufactured gas pipelines.

Below Ground Building Entry Fitting. Kitemark approved to GIS/PL3 Maximum working pressure: SDR17 = 2bar. SDR11 = 5.5bar Temperature Range: -20°C to +40°C The Donkin Series 218 underground entry fitting is a simple transition fitting to connect PE service pipes into the. interior of a building via an underground entry.

GIS/PL3:2014 v Foreword Gas Industry Standards (GIS) are revised, when necessary, by the issue of new editions. Users should ensure that they are in possession of the latest edition. Contractors and other users external to Gas Transporters should direct their requests for copies of a GIS to the department

Connection to the service pipe is either by crimp or factory fitted GIS/PL3 connection and the internal connection is by BSP screwed thread. These fittings contain an integral plug that allows the gas flow to be
