Pipework & Tie-Ins

Pipework turns a row of equipment into a working process. We fabricate and install the process, utility and dosing lines, and make the tie-ins into existing plant — often the most delicate part of a brownfield project.

Pipework and Tie-Ins in Detail

What we install

Process and utility pipework, valves, strainers and dosing lines in the materials each stream demands.

  • Process, recycle, drain and vent lines
  • Utility air, water and steam pipework
  • Chemical dosing and sample lines
  • Valves, actuators, strainers and supports

Tie-ins to existing plant

Connecting new plant to a running works needs careful isolation, sequencing and testing to avoid disrupting production.

  • Isolation, drain-down and permit control
  • Planned shutdown or live tie-in sequencing
  • Hydrostatic / pressure testing before service
  • Reinstatement and flushing of new lines

Standards & Deliverables

Pipe spooling Hydrotest Valves & actuators Brownfield tie-ins Flushing

Pressure-tested, flushed and labelled, the pipework hands the plant to the E&I phase ready for instruments, power and control to bring it alive.

Other Installation Phases

Planning an installation?

Reynolds & Bauhm delivers installation as a single coordinated scope — survey, erection, pipework, E&I, commissioning and handover — with one accountable team from delivery to performance sign-off.

Pipework & Tie-Ins Without Disrupting Operations

Connecting new plant into a live site is among the most delicate parts of any installation, and we plan tie-ins as a controlled operation rather than a disruption. Connection points are surveyed, isolation and drain-down agreed, and the work sequenced into windows that keep the existing process running wherever possible. Pipework is fabricated to the isometrics, pressure-tested and flushed before it is brought into service, and every joint is recorded. Hot-tapping, line-stops and temporary bypasses are used where a shutdown would be unacceptable. The outcome is a clean, leak-tight connection between old and new, made safely and with the minimum interruption to the client’s production.
