East Ham LMD

Depot Heating Pipework Replacement

Overview

EWG was engaged to carry out a full replacement of critical heating pipework at East Ham Light Maintenance Depot (LMD), following a system failure identified through non-destructive testing (NDT). The works involved pipework fabrication and installation, full insulation replacement, and thermal cladding — all while managing site-specific risks near operational lines.

The Objective

Restore full functionality to the depot’s boiler system by replacing failed and life-expired pipework, improving thermal efficiency and ensuring long-term reliability.

Challenges

  • Ageing Infrastructure

    The existing 150mm flow/return lines were deteriorated and required full strip-out and replacement.

  • Proximity to Live Lines

    Works were adjacent to active railway tracks, introducing logistical limitations and safety constraints.

  • Site Access & Clearance

    Vegetation obstruction and undefined skip placement required flexibility in on-site planning.

Our Solution

  • Pipework Replacement

    Removed all old pipework, fabricated and installed new sections including flanges, joints, and fittings to reinstate the boiler system.

  • Thermal Insulation & Cladding

    Installed approx. 320 linear metres of 40mm foil-faced glass wool insulation, finished with riveted aluminium cladding. Included fabrication and fitment of 8 muff covers and 20 bends for full coverage.

  • Waste Management

    Stripped insulation and waste were safely removed to designated skip locations in compliance with environmental protocols.

Results

  • System Restored

    Boiler system brought back into operational use with improved thermal retention and lower heat loss.

  • Upgraded Insulation Standards

    Modern, weather-resistant cladding offers long-term protection and reduces maintenance frequency.

  • Ready for Winter Operations

    The depot’s heating infrastructure is now fully functional, reliable, and energy-efficient in time for colder periods.
