SGN gas network - Scotland

SGN create 4 separate data layers (by pressure tier) to depict the location of their gas network:

LP - Low Pressure (19 mbar - 75 mbar)

MP - Medium Pressure (75mbar - 2 bar)

IP - Intermediate Pressure (2 bar - 7 bar)

HP - Regional High Pressure (>7 bar)

In order to assess the risk of planning applications affecting the gas infrastructure, there is a requirement to buffer the above pipe network by different distances. The Spatial Hub has provided these buffered polygons as separate data layers. These are consultation zones where SGN should be informed about relevant planning applications. Major developments with potentially widespread effects should have larger consultation distances of up to 1km: e.g. quarrying, deep mining, demolition, blasting, siting of High Voltage Infrastructure.

Current buffers:
HP buffer (75m either side of pipe - 150m total)

IP buffer (25m either side of pipe - 50m total)

MP buffer (12.5m either side of pipe - 25m total)

The gas network data is up to date at the time of publication, but it is given without warranty as to the accuracy of the information shown. Service pipes, valves, siphons, sub-connections etc. are not shown but their presence should be anticipated. No liability of any kind whatsoever is accepted by SGN or its agents, servants or sub-contractors for any error or omission.

Should the user wish to excavate in the vicinity of pipelines, the User should visit SGN via sgn.co.uk/Safety/Dig-safely for further information. SGN use an on-line mapping system, accessible via the sgn.co.uk/Safety/Dig-safely web pages or linesearchbeforeudig.co.uk, this process should be used to obtain up to date maps and safety information before you excavate. However if you need more information please contact our Safety Admin team on 0800 912 1722 or by email: [e-mail].

For the avoidance of doubt, safe digging practices, in accordance with HS (G) 47, must be used to verify and establish the actual position of mains, pipes, services and other apparatus on site before any mechanical plant is used. It is your responsibility to ensure that this information is provided to all persons (whether direct labour or contractors) working for you on or near gas apparatus.

Mains shown in the data are those owned by SGN by virtue of being a licensed Gas Transporter (GT). Gas pipes owned by other GT’s, or third parties, may also be present in the area and are not shown in the data. Information with regard to such pipes should be obtained from the relevant owners

SGN 创建了4个按压力层级划分的独立数据图层，用于展示其燃气网络的分布情况：
低压（LP，Low Pressure）：19 毫巴至 75 毫巴
中压（MP，Medium Pressure）：75 毫巴至 2 巴
次高压（IP，Intermediate Pressure）：2 巴至 7 巴
区域高压（HP，Regional High Pressure）：大于7 巴

为评估影响燃气基础设施的规划申请风险，需针对上述管网设置不同距离的缓冲区域。空间枢纽（Spatial Hub）已将这些缓冲多边形作为独立数据图层提供，这些区域即为咨询区，SGN 需被告知相关规划申请事宜。对于可能产生广泛影响的大型开发项目，咨询距离应设置为最大1公里，例如采石、深层采矿、拆除、爆破以及高压基础设施选址等场景。

当前缓冲区设置如下：
高压管道缓冲区：管道两侧各75米，总宽度150米
次高压管道缓冲区：管道两侧各25米，总宽度50米
中压管道缓冲区：管道两侧各12.5米，总宽度25米

本燃气网络数据在发布时为最新版本，但不对所展示信息的准确性提供任何保证。数据未包含服务管道、阀门、虹吸管、分支连接点等设施，但应预判其存在。SGN及其代理、雇员或分包商不对任何错误或遗漏承担任何形式的责任。

若用户需在管道附近进行开挖作业，应通过访问 sgn.co.uk/Safety/Dig-safely 网站向SGN获取进一步信息。SGN 提供在线地图系统，可通过 sgn.co.uk/Safety/Dig-safely 页面或 linesearchbeforeudig.co.uk 访问，在开挖前应通过该流程获取最新地图及安全信息。如需更多信息，可联系安全管理团队，电话：[phone]，或发送邮件至 [e-mail]。

为明确起见，在使用任何机械施工设备前，必须遵循HS (G) 47标准的安全开挖规范，核实并确定现场主管线、管道、服务设施及其他装置的实际位置。您有责任确保所有为您在燃气设施上或附近工作的人员（包括直接劳工或承包商）均已获取该信息。

本数据中展示的管线为SGN作为持牌燃气运输商（Gas Transporter，缩写GT）所拥有的主管线。区域内可能存在其他燃气运输商或第三方所有的燃气管道，但未在本数据中展示，相关管道信息应向对应所有者获取。
