All pipes of course must be designed for all aspects of exposure, including suitability for available handling, joining, and installation qualities, adequate strengths ands safety factors in all directions for all manners of expected service loadings (including internal and external pressures, intentional or incidental beam loadings, thrust restraint etc.), damage resistance, temperatures involved and effects of same, as well as internal and external corrosion resistances, permeation issues when applicable etc. While I think the claim below of "with out any maintenance" is a quite lofty goal in universal practical application, the capabilities and durability of say coated and lined steel or ductile iron piping and their joining systems are generally well-known and appreciated, compared in some cases to less proven alternatives. Where maintenance (say damage repair or other?) is needed, these metallic pipes can also generally be rather expeditiously repaired with available methods and devices as well.

Dear All
Please note that for cooling and sea waters of Refinereis it is better to use FRP piping systems as they are non corrsoive and provides longer service life with out any maintance
AWWA C-950 and M 45, BS5480, and ASME B 31.3 codes support these non mettalic pipes
above is for your information

do you need for the same purpose?

Re: [PipingDesign] 68" pipe

Please specify the fluid to be handles and Pr/Temp. of the service.

Then only some suggestion can be given.
How ever such big sizes are generally used with cement pipes, CS+cement lined, only CS, or FRP pipes.

With best regards.
