Practical Engineering. Industrial Precision. Reliable Performance.
Engineering partner since 2014
We engineer portable machining, controlled bolting, flange maintenance, hydrotesting and high-pressure hydraulic solutions around real load conditions, duty cycles and site access.
01 — Who we are
HAYA TEQ started in 2014 supporting construction and commissioning projects. We wrote the procedures and built the tooling before we ever supplied equipment — so every product in the range carries the memory of a joint that had to be closed correctly, on a deadline, in the field.
That order matters. Materials, tolerances and finishes are selected against real load conditions, duty cycles and site access — not catalogue assumptions. The result is equipment that survives repeated use in harsh environments, reduces downtime and stays serviceable long after commissioning.
02 — Product lines
Scroll to walk the range. Each line is engineered around the joint it has to serve — access, load path and duty cycle.
01Machine the joint where it stands.
Clamp-on machining equipment for pipe beveling, cutting, flange facing and weld preparation — performed in situ, so lines and vessels never leave service for a workshop visit.
02Preload you can put a number on.
Hydraulic torque wrenches, power packs and reaction accessories engineered for repeatable bolt preload on flanged joints, pressure vessels and structural connections.
03Open, align, close — without the pry bar.
Mechanical and hydraulic spreaders and alignment tooling that take manual force, improvised levers and pinch-point risk out of flange breaking and joint make-up.
04Prove the system before it goes live.
Air-driven and electric hydrostatic test units with calibrated instrumentation, chart recording and controlled ramp rates for pipeline, vessel and valve pressure testing.
05Controlled force, exactly where you need it.
High-pressure cylinders, pumps and hose sets for lifting, pulling, pressing and precision positioning during heavy maintenance, installation and turnaround work.
Not on the list?
Where standard tooling does not suit the access, load path or site conditions, we engineer and manufacture to yours.

03 — Why HAYA TEQ
Technical expertise combined with field-proven practice. Every tool is specified to meet the demands of real operations — precision, reliability and performance you can plan a shutdown around.
Tolerances, surface finish and repeatability specified against the joint the tool actually has to serve — not a catalogue average.
Materials, seals and duty cycles selected for offshore humidity, desert heat and shutdown workloads that run around the clock.
Faster joint turnaround with fewer people in the line of fire — efficiency measured in critical-path hours recovered, not brochure claims.
Every design decision is driven by real load conditions and site realities, so tools stay in service long after commissioning.

05 — Engineering tool
Work out an indicative target torque from bolt size, grade, lubrication condition and required preload — then see which tool class covers it.
Joint parameters
Result
Indicative only. T = K·d·F assumes a uniform nut factor; actual preload depends on friction, gasket relaxation, joint stiffness and tightening sequence. Always work to the project torque procedure and applicable standard.
06 — Applications
Precision assembly, maintenance and shutdown activity — the work that sits on the critical path.
Documented preload on critical flanged joints.
Break, align and re-make joints without improvised tooling.
Bevel, face and cut in place — no dismantling.
Controlled pressure verification and leak detection.
Synchronised jacking, load transfer and positioning.
Tool packages sized to the critical path.
Readiness checks, procedures and handover records.
Routine and breakdown intervention across rotating and static assets.
07 — Services
A complete range of engineered industrial tooling and field services, built around the way shutdowns, turnarounds and commissioning campaigns actually run.

Test planning, equipment readiness and procedures for a clean handover to operations.
Asset tracking, calibration records and maintenance planning across the equipment lifecycle.
08 — How we work
We do not start with a product code. We start with the duty the connection has to survive, and work back to the tool that will deliver it repeatably.
We start with the actual duty: bolt size and grade, gasket, access, medium, temperature and the standard you are working to.
Tool selection or custom design against real load conditions, duty cycles and site constraints — with the calculations to back it.
Calibrated equipment, procedures and documentation delivered to site, with rental or purchase structured around your campaign.
On-site assistance, recalibration, repair and spares so the asset stays certified and available for the next shutdown.
09 — Technical FAQ
Something specific to your joint, standard or shutdown window? Our engineers answer directly — no call-centre.
Request technical supportOnsite machining brings portable machine tools to the equipment instead of sending components to a workshop. Clamp-on lathes, split-frame cutters and flange facers perform beveling, cutting, facing and weld preparation in place. It is used when dismantling is impractical, when the item is too large to transport, or when the shutdown window is too short to allow removal, transport and refit.
A hydraulic torque wrench applies a controlled, measurable torque that can be tied to a target bolt preload and recorded against the joint. Impact tools deliver an uncontrolled, unrepeatable output. On flanged joints, pressure vessels and structural connections, documented and repeatable preload is what protects joint integrity — which is why controlled bolting is specified on critical services.
Our controlled bolting range spans roughly 150 Nm to 72,000 Nm across square-drive and low-clearance hex cassette formats, driven by 700 bar (10,000 psi) hydraulic power packs. Tool selection depends on bolt diameter, grade, lubrication condition and the access available around the joint.
Yes. Rental is available for shutdowns, turnarounds, commissioning campaigns and temporary projects. Equipment is supplied calibrated and certified, and can be packaged with procedures, on-site technical support and field supervision.
Custom engineering is a core part of what we do. Where standard tooling does not suit the access, load path or site conditions, we design and manufacture to your specification — dimensioned against the real duty rather than a catalogue assumption.
We support oil and gas (onshore and offshore), petrochemical, power generation, renewables, steel, cement, sugar processing, marine, fertilizer, water and heavy industrial maintenance. Supply and support extends across Australia, Asia, the United States and the Middle East.
