Capabilities

Services built for live, in-place industrial work

Every service line below exists because operators needed the work done without dismantling the system. Scope it with us and we bring the method, the tooling and the crew.

Field Machining Hot Tapping Line Stops / Line Stopping Line Freeze Technical Bolting Heat Treating Technical Consulting Industrial Painting & Protective Coatings Equipment Sales Equipment Rentals

Restore sealing surfaces without removing the equipment from the line.

Field Machining

Portable machine tools are mounted directly to the equipment and indicated off an existing datum, so gasket faces, seats and bores are cut concentric and flat in place. Cut depth, flatness and finish are recorded against the applicable flange or seat specification.

What we do

Flange facing and gasket-surface refinishing, including gasket-surface repair on a new 8 in. Class 600 cryogenic PSV
Valve seat and sandwich-valve machining in place
Mounting-surface resurfacing in place, including API 610 VS1 vertical turbine pump / sump can top mounting surfaces
Line boring, milling and drilling with portable machine tools

Applications

Leaking flanged joints with distorted or corroded gasket faces
Valves that will not seat after service exposure
Vessel, drum and sump-can sealing faces that cannot be shipped out
Mounting surfaces requiring flatness correction before reassembly

Add branches and tie-ins while the system stays live and in service.

Hot Tapping

A fitting is installed on the pressurized header, tested, and cut with a tapping machine through a full-port valve. The coupon is retained on the pilot cutter and recovered, leaving a finished branch connection without depressurizing the system.

What we do

Hot taps on live natural-gas and crude-oil service, including an 8 in. hot tap on a live natural-gas line
Large-diameter interventions up to 36 in.
Fitting review, coupon retention and pressure-test procedures
Coordinated with client operations and permit-to-work requirements

Applications

New instrument, injection or drain connections on live headers
Tie-ins for plant expansions with no available shutdown
Access points required ahead of a line stop or freeze isolation
Sampling and pressure-monitoring connections on transfer lines

Create a safe work window without draining or depressurizing the system.

Line Stops / Line Stopping

Hot taps are made either side of the work area and stopping heads are inserted to hold isolation while the repair proceeds. Bypass arrangements can maintain throughput, and the fittings are plugged and completed at the end of the window.

What we do

Single and double block line stops on liquid and gas systems
36 in. hot tap / line stop on a crude-oil transfer line at an offshore Gulf repump station
Bypass planning to maintain throughput during isolation
Full-cycle execution: tap, stop, work window, completion and plugging

Applications

Valve replacement on lines with no upstream isolation
Spool or fitting replacement on live transfer piping
Emergency repair of a damaged or leaking section
Isolation for tie-in work while product keeps moving on bypass

Isolate flow cryogenically when mechanical stops are not an option.

Line Freeze

Liquid nitrogen jackets are applied to a static column of product to form a solid plug. Plug growth and thaw are temperature-monitored throughout, and no penetration of the pipe wall is required.

What we do

Nitrogen freeze isolation on small- and mid-bore lines
Temperature monitoring and controlled thaw sequences
Used to support valve replacement and instrument tie-ins
Applied where line geometry rules out a mechanical stop

Applications

Small-bore valve and instrument replacement
Lines where a hot tap is undesirable or not permitted
Short-duration isolations on water, glycol and process service
Isolation upstream of gasket or packing replacement

Hold critical joints with documented torque or tension values.

Technical Bolting

Joints are made up to a calculated target using hydraulic torque or tensioning, in a controlled pattern and in stages, with the achieved values recorded per stud so the joint can be defended after the fact.

What we do

Hydraulic torque and tensioning on flanged connections
Joint integrity procedures with documented values
Gasket selection support and surface-condition verification
Pressure-drum repair support and documented joint integrity

Applications

Exchanger and vessel covers returning to service
High-consequence flanged joints after machining or gasket change
Repeat-leak joints requiring a controlled make-up procedure
Turnaround work packages that require documented joint records

Control thermal cycles in the field for weld and joint integrity.

Heat Treating

Resistance heating elements and insulation are applied to the component and controlled in zones against thermocouple feedback, holding ramp, soak and cool rates to the applicable procedure with a chart or digital record of the cycle.

What we do

Resistance heating with multi-zone control
Pre-heat, PWHT and stress-relief cycles to specification
Chart and digital records supplied with the work package
Coordinated with welding and machining scopes on the same outage

Applications

Post-weld heat treatment of field welds on piping and vessels
Pre-heat support for heavy-wall welding
Stress relief after in-place repair or modification
Coordinated PWHT within a machining and bolting scope

Technical Consulting

Method development based on field execution rather than theory: what the equipment will tolerate, what tooling actually fits the access available, and the sequence that gets the system back in service inside the window.

What we do

Taper Lock heat-exchanger transition consulting in Latin America
Repair-versus-replace assessments for in-service equipment
Method statements, tooling selection and sequencing
On-site technical oversight during critical work windows

Applications

Transitioning exchanger closures to a different sealing arrangement
Deciding between in-place repair and replacement
Writing method statements for a first-time intervention
On-site oversight during a high-consequence work window

Protect equipment with spec-compliant surface prep and coating systems.

Industrial Painting & Protective Coatings

Surface preparation to the specified profile, masking of sealing faces and instrumentation, then primer and topcoat applied to the required film thickness with containment suited to an operating facility.

What we do

Surface preparation, priming and multi-coat protective systems
ALCO V16 marine-engine coating work
Corrosion protection on piping, drums, valves and structures
Containment and controlled application in operating facilities

Applications

Marine and large-bore engine refurbishment coatings
Corrosion protection on drums, exchangers and piping
Structural steel and skid recoating during outages
Recoating equipment immediately after in-place repair

Buy the same field-proven equipment and tooling we run on our jobs.

Equipment Sales

Equipment specified against the application — flange size and class, access, and duty cycle — rather than against a fixed catalogue, with consumables and spares support after delivery.

What we do

Field-service support equipment and tooling
Consumables, tooling and spares support
Specification guidance based on real field application
Inquiries handled directly by our field team

Applications

In-house maintenance teams building their own capability
Contractors standardising tooling across crews
Spares and consumables for equipment already in service
Specification review before a capital tooling purchase

Rent the right machine for the joint — with or without our technician.

Equipment Rentals

Rentals are matched to the flange or tap size, class and available access, supplied with the tooling and consumables needed for the scope, and available with a technician for set-up or full execution.

What we do

Flange facing machines sized to the joint and access
Cold tapping equipment for un-pressurised tie-in work
Hydraulic power units, hoses and support tooling
Optional technician support for set-up or full execution

Applications

One-off flange facing scopes on a planned outage
Cold tap connections on isolated or drained systems
Peak-demand coverage when your own tooling is committed
Trial of a machine class before purchasing

Combined scopes

One mobilization, several disciplines

Most jobs are not a single service. A line stop opens a window; machining restores the sealing face; heat treating and bolting close it back up; coatings protect what you just repaired. Running those scopes with one crew removes handoffs and shortens the outage.

Isolation & intervention
Sealing-surface machining
PWHT & stress relief
Documented bolting
Protective coatings
On-site technical support

Multi-zone heat treating power consoles and heater cables staged for a field thermal cycle
