natural gas distribution pipeline pressure

This is more than all about 15 of the nation’s 1,000-plus gas utilities. ASTM F2138 and ASTM F1802 cover the specification and testing of EFV’s.PE piping must be joined using procedures conforming to CFR 192that have been qualified by test in accordance with CFR 192.283 and proven to make satisfactory joints.

The California Public Utilities Commission (CPUC) regulates natural gas utility service for approximately 10.8 million customers that receive natural gas from Pacific Gas and Electric (PG& E), Southern California Gas (SoCalGas), San Diego Gas & Electric (SDG& E), Southwest Gas, and several smaller natural gas utilities.

Personnel making the joints in plastic pipe must be qualified in accordance with CFR 192.285, under the submitted and approved procedure by making a satisfactory specimen joint that passes the required inspection and test. PE pipe was first used in 1961 for natural gas distribution lines.According to the Plastics Pipe Institute, PE pipe represents the material of choice for most gas distribution applications in North America and throughout the world. Entering at the source In a typical natural gas field, a number of small gathering lines lead from each well to gas processing facilities. Historically, some incidents have been attributed to failures at the connection as detailed in report number SIR-98/01 published by the National Transportation Safety Board. For US applications, its use is governed by CFR Title 49 Part 192 which prescribes the design, installation, maintenance, repair, and integrity management of plastic piping. Flexible pipe, such as thermoplastic and fiberglass, are typically designed to rely on the stiffness of the soil surrounding the pipe for support. AGA XR0603 includes procedures, recommendations, and remarks that are intended to illustrate these requirements as they apply to plastic.Plastic service lines may be connected to metal mains using fittings with compression ends or other transitions connections. The distribution of gas mains vs gas service pipe was about 50-50.Other pipeline materials used below-grade are fiberglass reinforced plastic (FRP), PVC, PE coated carbon steel, and cast iron. c) The embedment materials are coarse-grained, compacted to at least 85% Standard Proctor Density, and have an E’ of at least 1,000 psi (6.9 MPa). It is not the intent of this document to reduce these codes to two or three paragraphs.For the purposes of this article, discussion will be limited to pipelines installed in location classes 3 and 4 (suburban and urban environments) and in low pressure distribution systems and service lines (downstream of transmission systems) and for pipelines NPS 12 (DN 300) and smaller.In the September 2019 Plumbing Engineer article on “Natural Gas Pipeline Systems on Site Distribution – Pipeline Materials and Installation Requirements,” the discussion centered on using carbon steel piping for above-ground installations and polyethylene (PE) piping for below-grade installations. Transmission and Distribution Transmission. AGA recommends a minimum pipe depth for mains to be 24” (610 mm).If the burial installation falls outside of the AWWA M-55 Design Window, the PPI Design of PE Piping Systems, Chapter 6, Section 3 provides detailed calculations for verifying the capacity of the piping system to resist crushing. The concern here being that the pipe can be accidently crushed due to soil pressure or imposed surface loads; especially when there is no pressure in the pipe. The owner’s representative needs to work closely with the natural gas supplier and follow his rules, regulations, and recommendations in any installation since the supplier will be most familiar with the local rules applicable to the project. Once the piping is installed, if the piping burial depth is less than 36 inches it is important to protect the pipelines by covering the trenches with protective barriers if major truck loads are expected to cross the pipeline path.A buried PE pipe is generally well restrained by soil loads and will experience very little lateral movement. The size of the anchoring block will vary depending on soil conditions and the thrust load as calculated via the following equations:σ = Stress in pipe created by the expansion/contraction of the material, psi (N/mmE = Apparent modulus of elasticity for the pipe material, psi (N/mmDo= Outside diameter of the pipe material, inches (mm) Di = Inside diameter of the pipe material, inches (mm) Once the forces are determined based on the soil temperatures are expected, then anchor blocks will need to be designed. Also, if the native soil is of poor quality, the stability of the soil can be improved in the area of the pipe trench with improved backfill materials. Keep in mind, that most of the constraints outlined in the AWWA M-55 Design Window are recommended installation techniques for plastic as well as PE piping.Underground, PE, natural-gas piping should be installed according to ASTM D 2774 Standard Practice for Underground Installation of Thermoplastic Pressure Piping. Pipes NPS 2 (DN 50) and smaller would still be threaded; generally threading and unions would be limited to installation of valves and regulators that would require periodic maintenance and replacement.

Natural gas delivered by the network has been a mainstay of our energy system for more than 50 years.
