Technical specifications
The standards we design and build to. Share this page with your project manager, architect or QS — full project-specific specifications are issued with every quotation.
Pressure stages
- Tank / manifold vapour
- Tank pressure, ambient dependent
- After first stage regulation
- Intermediate service pressure to risers
- After second stage regulation
- Appliance pressure, typically 28–37 mbar for LPG
- Design pressure drop
- Held within allowable limits at full diversified flow
Pipework materials
- Buried service
- Sleeved steel or approved polyethylene with tracer and warning tape
- Risers and laterals
- Steel or copper to recognised standard, brazed or approved fittings
- Concealed runs
- Sleeved, ventilated and non-jointed within the sleeve
- Supports and spacing
- Fixed at standard intervals with expansion allowance
Testing and commissioning
- Strength test
- Pneumatic or hydrostatic test above design pressure, held and recorded
- Tightness test
- Pressure hold with no permissible drop over the recorded period
- Regulator checks
- Lock-up and working pressure verified at each stage
- Appliance checks
- Flame quality, ventilation adequacy and combustion verification
Metering and control
- Per-unit metering
- Mechanical or prepaid smart meters with tamper detection
- Billing integration
- Tenant top-ups by M-Pesa, dashboards for landlords
- Detection
- Fixed detectors at LEL thresholds with solenoid shut-off
- Emergency stop
- Manual call points at exits and the storage compound
