Several types of valve connections for propane, butane, and LPG containers exist for transport and storage, sometimes with overlapping usage and applications, and there are major differences in usage between different countries. Even within a single country more than one type can be in use for a specific application.
Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. [1] " Nominal" refers to pipe in non-specific terms and identifies the diameter of the hole with a non-dimensional number (for example – 2-inch nominal steel pipe" consists of many varieties of steel pipe with the only criterion being a 2.375-inch (60.3 mm) outside ...
Only propane produced specifically for use in refrigeration systems – with a purity of at least 98.5% and moisture content below 10ppm (by weight) – should be used. [ 1 ] With a global warming potential (GWP) of 0.072 [ 2 ] and an ozone depletion potential (ODP) of 0, R-290 is of very little threat to the environment.

The International Fuel Gas Code (IFGC) is published by the International Code Council through the governmental consensus process and is updated on a three-year cycle to include the latest advances in technology and safest mechanical practices. [1]
Common absorption refrigerators use a refrigerant with a very low boiling point (less than −18 °C (0 °F)) just like compressor refrigerators.Compression refrigerators typically use an HCFC or HFC, while absorption refrigerators typically use ammonia or water and need at least a second fluid able to absorb the coolant, the absorbent, respectively water (for ammonia) or brine (for water).
LPG is composed mainly of propane and butane, while natural gas is composed of the lighter methane and ethane. LPG, vaporised and at atmospheric pressure, has a higher calorific value (46 MJ/m 3 equivalent to 12.8 kWh/m 3 ) than natural gas (methane) (38 MJ/m 3 equivalent to 10.6 kWh/m 3 ), which means that LPG cannot simply be substituted for ...
