Thank you for your reply.

Referring  fig 127. 3 in B31-1, give tolerance of weld joint prior to fit-up.I am asking tolerance of pipe straightness/ verticality and elevation while installing pre-assembled pipe spools

Dear Experts,

Construction code - ASME B.31.1 (Fuel gas system)

Service - Fuel gas system

I wanted to know how much tolerance can accept  while doing piping alignment inspection like straightness checking , elevation checking dimensional checking etc

Nothing was mentioned in contract documents and project specification.

Please provide the reference.
