MDPE Yellow Gas Pipe

MDPE Yellow Gas Pipe is a medium-density polyethylene pipe specifically designed and colour-coded for underground gas distribution systems, offering durability, flexibility and secure gas transport.

About MDPE Yellow Gas Pipe

MDPE yellow gas pipes are engineered for underground gas supply networks. The distinctive yellow colour indicates suitability for gas applications and is a critical safety identifier. These pipes are lightweight, resistant to impact and corrosion, and ideal for long-term underground installations.

Typically installed with electrofusion or mechanical fittings, MDPE gas pipework is used for service connections to properties and commercial or industrial gas distribution where approved. All gas installations must be carried out by qualified engineers in accordance with local gas safety regulations.

Installation & Technical Info

Pipe should be installed in accordance with gas safety regulations (e.g., BS 6891, IGEM/TD/3) by a Gas Safe registered engineer. Trench preparation should follow guidelines, using appropriate bedding material and maintaining minimum depth requirements.

Pipe joints should be made using approved gas-rated fittings. Pressure testing must be completed before commissioning. Protect pipe from prolonged UV exposure before installation.
