Technical Standards
Safety codes and specifications for natural gas pipe systems, governed by ASME, ISO, IGEM, and local EWURA requirements. Safety, integrity, and efficiency — built in by design.
Key Technical Standards & Organisations
Natural gas pipe systems are governed by internationally recognised technical standards covering materials, design, welding, testing, and maintenance.
American Society of Mechanical Engineers
International Organization for Standardization
Institution of Gas Engineers and Managers
American Petroleum Institute / American Welding Society
Natural Gas Safety Codes
Key rules from the IFGC and local regulations to prevent leaks, explosions, and carbon monoxide exposure.
Piping Installation
- Gas pipes must not be installed in chimneys, elevator shafts, or air ducts.
- Concealed piping should not be placed in solid walls unless in a protected chase.
- Must adhere to accurate sizing to maintain safe pressure drop limits.
Appliance & Ventilation
- Appliances must not be installed in bathrooms or sleeping rooms unless direct-vented.
- Proper combustion air must be provided to prevent carbon monoxide buildup.
- Gas appliances require regular inspection of flame safety devices and case seals.
Leak Detection & Maintenance
- Never use a match or open flame to check for leaks — use combustible gas detectors or soapy water.
- Keep areas around gas appliances (furnace, water heater) clear of flammable materials.
- Only qualified, EWURA-licensed personnel should install or repair gas equipment.
Excavation & Electrical
- Always call before you dig — utilise services to locate underground pipelines.
- Gas lines must be bonded to the building's electrical system for earthing safety.
- Strict tightness testing and direct purging procedures must be followed before commissioning.
Common Regulatory Standards
IFGC — International Fuel Gas Code
Covers design and installation standards for gas systems, widely referenced globally.
NFPA 54 — National Fuel Gas Code
Sets national standards for the safe installation of gas appliances and systems.
EWURA — Tanzania Local Standards
For local applicability, all gas system work must comply with EWURA licensing requirements and national safety standards.
For local regulations, always check with EWURA or TPDC.
International standards are a baseline — Tanzanian installations must comply with EWURA licensing and safety rules.
