Pipeline design

Pipe selection and wall thickness

The type of pipe and wall thickness must be determined for each application. Following the design requirements of Part 192 for natural gas, Part 193 for liquefied natural gas (LNG), and Part 195 for crude-oil and products pipelines, the pipe materials and wall thickness can be determined using the applicable formula. As discussed in the page on pressure drop calculations in piping and pipeline systems, the wall thickness will be determined by:

  • The operating pressure (maximum and normal)
  • Operating temperature
  • Other design factors (depending upon the type of pipeline and applicable regulation)
  • The pipe material

Material selection

Pipe fittings, flanges, and valves must meet the specification and pressure class of the pipe selected for pipeline applications.

Route selection and survey

Route selection is very important to successful pipeline design. This requires careful study of the:

  • Terrain
  • Natural obstacles, such as
  • Mountains  Swamps   Marshes  Rivers
  • Manmade obstacles, such as
    • Highways
    • Roads
    • Railroads
    • Buildings
  • Population density

Some helpful aids in the routing process include:

  • Topographic maps
  • Aerial photography
  • Satellite imagery
  • Property ownership maps
  • Physical inspection

 

Corrosion prevention

Steel pipe and pipeline facilities must be protected from the effects of external and internal corrosion. Nonferrous piping materials, such as fiberglass, PVC, and polypropylene, do not undergo the same corrosive effects and require little attention. Industry codes and standards and the DOT regulations require that pipelines, appurtenances, and facilities be protected from the effects of corrosion.



Welding and pipe joining

The methods used to connect the joints or pipe segments are very important and are critical to the pipeline design.



Offshore pipelines

Offshore pipeline design differs primarily in the requirements of the environment and the installation process. Pipe used in offshore applications is subjected to high bending stresses—potential crushing forces on pipe installed in deep water and a low-density environment. Until recently, the pipeline size was severely limited, but technological developments and improved construction methods have enabled offshore pipelines to continue to increase in size and capacity. Pipelines are being constructed in deeper and deeper waters. Pipelines up to 28-in. diameter are now being installed in the deepwater applications up to 7,000 ft of water.
