Destec was formed in 1969, by the present owners of the company, and it has remained a Private Limited Company ever since.
For over 50 years of trading the company has developed both products and services to industry, particularly where design and supply is concerned, with ‘High Pressure Containment’ and ‘On-Site Machining’ being the specialist lines.
The management of the company had previously (1959 – 1969) been substantially involved in the design, manufacture, sales and marketing of ‘Ruston-Grayloc’ clamp-type pipe connectors and seals. From 1969 – 1972 Destec Engineering was engaged by Gray Tool Co. (Grayloc), to continue with all aspects of the high pressure pipe connector market, on its behalf.
Since 1969 Destec have been committed to the design and manufacture of portable machine tools, partly for installation and servicing of company products, and also as a general On-Site Machining Service. Destec now have a most versatile and very wide range of in-house designed and manufactured portable machine tools that can undertake most machine shop operations on-site, on a world wide basis.

Desflex Flanges are Type Approved and have successfully passed API Fire tests.
Destec door closures provide quick access to pressure vessels and can be operated safely at speed.
Applications include Industrial Waste Treatment closures, Pig traps, Separator vessels, Subsea Access Hatches and Medical Waste treatment vessels.
Sizes ranging from 0.5m to 2m diameter.
Designed to meet ASME and other pressure vessel requirements for quick release connectors.
Destec Engineering offer front end design studies to determine cost effective solutions and provide manufacture and project management with our own in-house technical expertise.
A range of doors has been developed for domestic waste treatment plants designed for continuous and remote operation.
Due to their efficiency, lightness and reliability, together with extreme qualities of leak tightness, the G-Range pipe connection offers significant benefits for use in industrial plant in a wide variety of applications. Although designed primarily for adverse pressure and temperature conditions, more modest applications can be considered due to ease-of-installation and assembly, particularly when compared with the alignment and tightening of standard flanges.
The G-Range pipe connection comprises: a pair of hubs for welding to the pipe (similar to a flange); a clamp set, which can be rotated around the hubs to suit the most practical positions; and a seal ring.
The seal ring is a modified cone ring giving excellent leak tightness properties under the most severe conditions of pressure and/or thermal shock.
On assembly the taper joint faces compress the seal ring radially. The sealing force is provided by the stored energy in the stressed seal ring, any internal pressure intensifies the sealing action.
Years of involvement in the oil & gas, petrochemical, power generation, and similar industries has allowed Destec Engineering Ltd to build up a portfolio of metrological and NDE skills. Up to date test equipment, allied with a strong skills base combining experience with formal training and qualifications gives us expertise in a wide range of inspection functions.
These are now available as a service at either our Washingborough site or, if applicable, at your location.
Positive Material Identification.
Destec Engineering Ltd can undertake positive material identification (PMI) using a Niton’s XL2 portable alloy analyser, identifying a wide range of elements. This can be used on raw materials, pipework, fittings and weld materials. Applications include:
Results can be demonstrated on a simple Pass/Fail basis, or a certificate can be generated giving individual elemental composition.
All operators are manufacturer trained, and have undertaken certified Radiation Protection training.
Many clients have drawn on Destec’s specialised knowledge and experience on the use of High Pressure and High Temperature metal-to-metal static sealing.
Destec have developed a sealing system which uses a modified cone ring giving excellent leak tightness properties under the most severe conditions of pressure, temperature, thermal cycling and shock.
Destec seal rings are being used as original equipment in client’s products and are also in service as replacement for original troublesome joints.
With conversions of old joints to Destec seals our engineers carry out the design modifications in accordance with established codes and standards, whilst the practical site work is handled by Destec’s on-site machining service using portable machines to carry out the modification and re-build on site.
The Destec GSB Subsea Single Bolt Connector is a purpose designed unit for operations where a conventional four bolt G-Range pipe connection would be impractical.
The GSB Connectors are supplied with a mounting plate which can if required accommodate guidance / pull-in systems for ease of alignment and provision for stab connectors for electrical and hydraulic circuits.
Standard G-Range or D-Range metal to metal Seal Rings can be used, or the customers own sealing arrangement can be employed.
Larger sizes and special designs (Dual Bore / Multi Bore / Concentric Bore) can also be accommodated. For example some GSB Connectors have been supplied with fabricated Spool pieces for mating to flexible risers.
For Subsea applications the GSB Connectors would be supplied with a combination of Molykote and Epoxy resin coatings. Designed for remote operations in the most demanding deep and ultra-deep water.
We have the experience and equipment for all bolt tensioning on site.
Hydraulic tensioners can be used with extended bolts. This method gives very controlled bolt stress levels as required when using conventional flat-faced joints.
The Ratchet Torque tensioner uses standard sockets and is one of the fastest methods of tightening heavy bolting.
Low Height Torque tensioners are used where access is limited and can be used only with one bolt diameter clearance at the end of a bolt. High pressure power packs, with reverse flow facilities, drive the double-acting cylinders of the torque tensioners for rapid bolt tightening.
A serious leak from a pipeline in a continuous process plant calls for a choice between three courses of action.

The service is available 24 hours a day, 7 days a week.
The Destec on-line leak sealing service can prevent loss of energy without loss of production.
By the use of specialised techniques, perfected over many years of practical experience, many millions of pounds of wasted energy are saved each year. This is achieved without plant or system shutdown while operations continue at full pressure and temperature.
In 1998, Destec Engineering 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.
Cutting of both the vessel shell and internal refractory was carried out dry, from the outside. and included all necessary weld preparation ready for reinstatement of the head.
The dry cutting operation is carried out using portable milling or grinding equipment running on two circumferential, parallel rails, fixed either side of the cut line. The method is relatively quick, with very little post operative cleaning – unlike water jet cutting, which can take as long as 10 days to 'mop-up'. Thus, the method effectively reduces overall plant down time and is very environmentally friendly.
Destec has designed, developed and built special purpose machines for the oil, petrochemical and nuclear industries.
This was a natural progression from the in-house designed and built on-site portable machines that have been used by our own technicians over the last 25 years.
Destec was awarded a design and build contract for Mobil for a machine to remove the regenerator head at Mobil, Coryton, the vessel was 9.4M diameter by 26mm thick with a 100mm think refractory lining. The work involved dry cutting both the vessel shell and internal refractory and also reforming of the weld prep. The machine design and operation were instrumental to the fastest turnaround for a unit of that size achieved by Mobil.
