SynC · Topic
These are the standards in the SynC Standards library that cover Natural Gas. Each one is a complete, plain-language specification: the scope it applies to, the requirements that govern it, and a structured equipment datasheet listing the values a project has to decide — ratings, materials, setpoints, and the standards each is verified against. All of it is free to read without an account and published under CC BY-SA 4.0.
A standard usually carries several topics, so most of the entries below also appear under neighbouring subjects. The topics each one carries are listed on its own page.
Packaged stationary engine-generator sets rated 1000 V and below, listed to UL 2200, furnished as the alternate source for emergency, legally required standby, optional standby, and critical operations loads, and sets the project applies as a prime or continuous source. Covers the engine and its fuel requirements by fuel type, the alternator and its excitation, the governor and voltage regulator, the set-mounted controller and the remote annunciator, the main line circuit breaker and the neutral bonding at the set, the cooling system, the fuel system on the skid including the sub-base tank, the exhaust silencer and aftertreatment, the enclosure and its sound attenuation, the starting batteries and charger, vibration isolation and seismic certification, factory and field testing, installation, warranty, and spare parts.
Field-installed fuel-gas piping conveying natural gas or undiluted liquefied petroleum (LP) gas from the utility meter or LP-gas second-stage regulator to gas-fired appliances and equipment, including interior distribution piping, exterior aboveground piping, and buried exterior service piping within the property line. Covers system pressure tiers (low-pressure systems at or below ½ psig and elevated-pressure systems at 2 psig and 5 psig with line-pressure regulators), pipe and tubing materials by service and location (Schedule 40 steel, polyethylene for underground use, corrugated stainless steel tubing, and copper where the gas sulfur content permits), threaded and welded joints, gas valves, line-pressure regulators with overpressure protection, sediment traps and appliance connections, corrosion protection of buried steel, electrical bonding of metallic piping and CSST, and the complete pressure-test and purging sequence required by NFPA 54.
