- Company Profile:
The American Gas Association represents local energy companies that deliver natural gas throughout the United States.
Generally mains, services, and equipment which carry or control the supply of gas from the point of local supply to and including the sales meters. The system operates at various pressures as indicated below.
*a. high pressure. a system which operates at a pressure higher than the standard service pressure delivered to the customer; thus, a pressure regulator is required on each service to control pressure delivered to the customer. sometimes this is referred to as medium pressure.
*b. low pressure or utilization pressure. A system in which the gas pressure in the mains and service lines is substantially the same as that delivered to the customers' appliances; ordinarily a pressure regulator is not required on individual service lines.
Industry:Energy
Rates designed to reflect the difference in pipeline costs based on the distance between supply sources and delivery points.
Industry:Energy

Industry:Energy
The right or privilege granted by a political subdivision to do business or perform specific services.
Industry:Energy
A condition wherein components of a piping system and/or different specific materials can be joined together to form satisfactory joints.
Industry:Energy
A material which extracts one or more substances present in an atmosphere or mixture of gases or liquids with which it is in contact due to an affinity for such substances.
Industry:Energy
A solid ice-like material resulting from the combination of a gas with water under pressure. Of natural gas constituents -- methane, ethane, propane, isobutane, normal butane, and also hydrogen sulfide and carbon dioxide will form hydrates. The greater the pressure in the equipment, the higher the temperature at which the hydrate will form, usually well above freezing. Hydrates can cause restriction or stoppage of flow, and can be controlled by alcohol injection or by dehydration of the gas. Methane hydrates are found in some permafrost regions and beneath portions of the ocean floor and may eventually be a source of methane gas.
