Our services

TIG welding. Pipe fabrication. And the skills to see it through.

Specialist welding and pipe fabrication lead our service. Mechanical engineering, installation and maintenance provide the support around them.

01

TIG welding & coded welding

Close-up of TIG welding in progress

TIG welding is a core TTN specialism, supporting precision fabrication in the workshop and on site. Welding procedures and qualification requirements are agreed against the specific scope.

  • TIG and other task-appropriate welding processes
  • Workshop and site fabrication
  • Welding documentation and inspection requirements
02

Pipe fabrication & installation

Pipe fabrication is central to our work: stainless steel and carbon steel spools, branches and assemblies, with site installation planned around the system and conditions of service.

  • Stainless steel and carbon steel pipework
  • Fabricated spools, branches, flanges and supports
  • Alterations and integration with existing plant
03

Mechanical engineering

Vertical pumps with stainless pipework and valves

Practical mechanical support for industrial plant and equipment, from installation and fitting to maintenance and overhaul.

  • Mechanical fitting and equipment assembly
  • Pumps and rotating equipment
  • Inspection, servicing and component replacement
04

Process plant installation

Crane positioned inside an industrial building for plant handling

Mechanical installation and relocation support for process equipment, coordinated around access, lifting arrangements and the wider site programme.

  • Equipment removal, positioning and installation
  • Mechanical connections and associated pipework
  • Recommissioning and handover support
05

Maintenance & shutdowns

Exposed screw assembly with bearing housing and drive components

Planned maintenance and shutdown support that starts with a clear understanding of the workface, plant availability and operating constraints.

  • Inspection and condition reporting
  • Repair, overhaul and replacement work
  • Site teams for planned maintenance periods
06

Materials handling

Fabricated hoppers and conveying equipment inside an industrial building

Fabrication, installation and maintenance support for the equipment that moves material through your process.

  • Conveyors and screw conveyors
  • Hoppers, chutes and transfer points
  • Mechanical alterations and replacement components
07

Bespoke steelwork

Orange fabricated access platform with black grating, handrails and access gates

Purpose-made steelwork and fabricated components to suit the application, working to agreed dimensions and project requirements.

  • Access platforms and handrails
  • Guards, brackets and support structures
  • Bespoke moulds and fabricated assemblies
08

Machining & component work

Portable machining equipment mounted inside a large circular flange

Component machining and engineering support as part of a coordinated repair, maintenance or fabrication scope.

  • Replacement and modified components
  • Shafts, fittings and mechanical interfaces
  • Work specified around drawings, samples and measured requirements

Project support & specialist services

Alongside our fabrication and installation work, TTN coordinates complementary services through specialist subcontractors, providing one point of contact for the agreed project scope.

  • Transport and delivery arrangements
  • Crane hire and contract lift coordination
  • Manufacture and supply of UKCA-marked steelwork through specialist fabrication partners
  • Hot-dip galvanising
  • Powder coating
  • Pump alignment and balancing
  • Non-destructive testing (NDT)
  • Hired-in plant
  • Scaffolding

These services can be incorporated into a wider TTN project package, from manufacture and inspection through to finishing, delivery and installation.
