On Site Services

Our wide range of versatile in-house designed and manufactured portable machine tools are well equipped to take on problems where accuracy and a good surface finish are paramount. Over the years we have added other associated on-site services, milling, boring, bolt tensioning, inspection services, on-line leak sealing, polymer coating and repairs, and welding. Our world-wide service successfully operates throughout all industries including chemical/petrochemical plants, offshore, power generation, renewable energy, nuclear, marine, steel, mining, ports, docks and harbours.

By using multi-disciplined trained technicians for our On-Site Services, the client benefits by having less personnel on site.

Regenerator and Vessel Head Removal

In 1998, Destec Engineering On-Site Services team performed a world first when it commenced preliminary cutting to remove the Regenerator Head at the Coryton Refinery, UK – 25 days in advance of day 1 of the planned turnaround start date, allowing the head to be lifted on mechanical day 2.

Heavy Plant and associated equipment vary so much in design, layout, size, age, conditions and even locations that any one factor can have a significant bearing on how a machining problem is tackled, especially during breakdowns. Plant maintenance departments will attend to whatever first-aid they can manage, but with the recognized advantage of calling in specialist services time can be saved and costs reduced.

The advantages are significant when compared win the alternative which could otherwise involve stripping down, transporting to a machine shop, returning to site, reassembly, as compared to taking a special purpose machine to the job.

Our engineers co-operate with clients on new plant and modifications, to give the most viable solutions for on-site machining. The service division offers a rapid response for maintenance and breakdown situations.

Most of the machines and equipment used have been designed and manufactured by Destec Engineering Ltd. Maximum versatility and adaptability combined with accuracy and a good surface finish ensure most In-Situ operations can be handled effectively and quickly.

Destec Engineering has carried out hundreds of conventional and unusual machining contracts on vessel and heat exchanger closures, piework flanges, nozzles, valve seats, offshore wind turbines etc, incorporating all types of profiles, such as spigots, recesses, tapers, grooves ranging from a fine to a gramophone surface finish.

Destec on-site machining includes:

Facing

Destec portable machines are equipped with variable speeds and automatic feeds to give good accurate surface finishes. Power feeds tool posts can be set for tapers, profiles, spigots and boring.

Oval Facing

For manways including spigoted joints. Destec’s purpose built machines generate true ellipses and machine to both fine and “Gramophone groove” finishes.

Boring

Precision in-line boring in any plane.

Pipe Cutting and Weld Preparation 

Destec’s patented tooling system will cut the thickest pipes in the hardest materials.

Milling

Universal milling machines that cut in any position with large feed ranges to limit set ups.  Our milling machines working range is up to 6 metres.

Keyway Cutting

Direct onto shafts with minimum clearance required.

Drilling and Reaming

We have portable equipment to cover all diameters and depths.

Thread Cutting and Tapping

Screw cutting of internal threads in either smooth bores or the rectification of damaged threads. We also machine tap when required

Trepanning

Machines can be adapted for trepanning to reduce machining cost and down time.

Welding

Welders are available for on-site weld overlay

NDT Services

NDT is Non Destructive Testing which is a method to detect that material is free from cracks, stress fractures and other types of defects.

As part of our Inspection services, Destec uses three types of non destructive testing comprising of magnetic partical, liquid penetrant and ultrasonic testing. Destec can use all methods in most cases anywhere. Also Destec have a dedicated in house NDT area. Read More.
