2.04 STEEL PIPE Gas main shall be new steel pipe meeting American Petroleum Institute Standard Specifications, as follows: Transportation of Natural and Other Gas by Pipeline Minimum Federal Safety Standards. Natural Gas Composition and Specifications. 1.1 This specification covers requirements and test methods for high-density polyethylene (PE) materials, pipe and fittings for pressure or non-pressure oil and gas producing applications to convey fluids such as oil, dry or wet gas, multiphase fluids, and non-potable oilfield water. Corrosion inhibitor: Basically meant for CS pipelines, forms a layer of film on the surface and protects the core pipe from corrosion attack. A53/A53M-02. Natural gas as recovered at the wellhead consists of mostly methane (C 1), but it contains other hydrocarbons, principally ethane (C 2), propane (C 3), butanes (C 4), and pentanes C 5 that constitute the natural gas liquids, as discussed in the previous section.

Steel is the material used in natural gas transmission systems pipes – these pipes are large in diameter and cover more than a quarter-million miles of our nation. Lined & Clad Pipe Most commonly used ASTM Material grades. This specification does not cover pipe for gas distribution applications. A106-02a. Transmission system pipe is made of 1/4-inch to 1/2-inch thick steel, and has special coatings and "cathodic" protection -- an electric current that controls corrosion on the metal surface through electro-chemistry. Standard specification for carbon steel forgings for piping applications.

Standard specification for pipe—steel, black and hotdipped, zinc-coated, welded, and seamless.
