Service Line, Pipefitting

Pipefitting.
Process and utility piping, end to end.

ASME B31.3 and B31.1 compliant process and utility piping installation, modifications, and tie ins, layout, cut, fit, weld, hydro, and turnover.

Nelvamar fitters work alongside Nelvamar welders on the same crew, under the same supervision, on the same contract. That eliminates the brokered labor hand off problems that plague Gulf Coast piping work.

Scope

  • New process piping installation (capital and brownfield)
  • Tie ins, hot taps, and pipe modifications
  • Utility piping, air, water, steam, nitrogen, fuel gas
  • Field routed and pre fab spool installation
  • Hydro and pneumatic testing

Codes & Practices

Process piping is delivered to ASME B31.3, power piping to ASME B31.1. We work to client specifications when they are tighter than code, and we document the difference in the turnover package.

Turnover

Line by line turnover packages: weld logs, hydro test charts, MTRs, isometrics marked as built, and any PMI or hardness records the spec calls for.
