Underground pipeline

Underground pipeline

Underground pipeline

(OP)
Hello,

Is it possible to use carbon steel (SA 106) sch.40 for underground pipeline carrying diesel fuel?
Can anyone tell me which API code I should refer to? I am looking for correct material.

Thanks in advance.

RE: Underground pipeline

Of course it is possible. Depending on diameter and length, it could be an expensive option.

RE: Underground pipeline

You don't need an API code just yet. BTW, APIs are not codes. As for a design code, is it a pipeline to be constructed outside of a plant area, an offshore platform, a diesel fuel system, or what?

RE: Underground pipeline

What is the application?

For generators, basic black iron pipe is the preferred material for any diesel fuel lines.

For fuel dispensing stations, you may use carbon steel:

  • ASTM A 53/A 53M, Schedule 40, Type S or E, Grade A or B, black.
  • Steel Threaded Fittings: ASME B16.11, with threads according to ASME B1.20.1.
  • Malleable-Iron Threaded Fittings: ASME B16.3, Class 150, standard pattern, with threads according to ASME B1.20.1.
  • Malleable
-Iron Unions: ASME B16.39, Class 150. Include brass-to-iron seat, ground joint, and threads according to ASME B1.20.1.

or nonmetallic:

Flexible Nonmetallic Piping: UL 971, plastic pipe and fittings for underground applications. Include bulkhead, termination, or other end fittings as required.

or ridgid nonmetallic:

Rigid Nonmetallic Piping: Fiberglass piping for underground applications. Include transition, bulkhead, termination, or other end fittings as required.

Or flexible double contained piping:

Flexible Double-Contained Piping: UL 971, flexible, nonmetallic, carrier pipe with flexible, nonmetallic, secondary-containment pipe, for underground applications. Include bulkhead, termination, or other end fittings as required.

Or ridid double contained piping

Rigid Double-Contained Piping: UL 971, RTRP and RTRF carrier piping with RTRP and RTRF secondary-containment piping.

RE: Underground pipeline

I would refer you to ASME B31.4, Pipeline Transportation Systems for Liquid Hydrocarbons and Other Liquids design. Then refer you to Table 423.1-1 Material Standards (A106B is there).
