Columns, Vessels, Heat exchangers and equipment, pre-heaters, turbines, piping and fittings, exhaust gas installations and filters, and incinerators. Thermal, Acoustic and Cryogenic insulations
- COLD INSULATION
Gas-liquefying plants, cooling towers and cold piping, fittings, liquid gas tanks, liquefying plants ( LNG ), water treatment plants.
- SOUND (ACOUSTIC INSULATION )
Compressor houses, fission furnaces, pumps and blast furnaces, piping and fittings, turbines and generators.
- CEMENTITIOUS FIRE PROTECTION.
As an alternative to in tumescent coatings:
- ABRASIVE BLASTING.
Abrasive blasting is generally only thought of as the first operation in the chain of events during corrosion control activities. However, abrasive blasting can also be utilized for the cleaning of many substrates and as a decorative tool for concrete floor or walled surfaces by exposing the aggregate in a predetermined pattern using masking boards cut and manufactured to the customs requirements.
CHEMICAL RESISTANT LINING
Nas Trust Corp. are also capable of applying epoxy coating systems and fiberglass linings to tanks, columns and pipelines both internally and externally for chemical resistance and surface strength build up.
A full range of G.R.P lining systems can be applied utilizing the many different ranges of resins such as polyester or vinyl esters. These systems can be applied with or without glass fiber builds up as a hand lay-up system or as a chop strand spray applied system.
- INTUMESCENT EPOXY COATING ( FIRE PROTECTION )
In tumescent coating are a fire protective material generally applied to steel structures in industrial environments particularly in the chemical, gas, hydrocarbon processing and offshore industries. Nas Trust Corp. can offer the service of in tumescent material application ensuring proper installation techniques and reliable fire protection of steel structures, tanks, pipelines etc. All applications are carried out by fully trained and certified personnel who have satisfactorily completed the material manufacturers training courses.
- INSULATION OF BUILDINGS.
Facades, air conditioning installation and heating plants, insulation of roofs.
- COLD INSULATION
Cooling – water and refrigeration plants, cold storage rooms and cells.
- SOUND INSULATION
Suspended ceilings, self supporting and removable walls, special door and windows, sound absorbing hoods.
Apart from the aforementioned fields of activity, which can be regarded as daily routine, the development conducted by Nas Trust Corp. becomes evident in the following projects.
- STORAGE & GAS LIQUEFACTION PLANTS
The knowledge gained in Polyurethane processing had already been largely applied to LPG/LNG plants, starting in 1976.
This was a break-through of new insulation method, but at the same time, Nas Trust Corp. Specialized in finding solutions to technical problems with regard to the storage and transportation of liquid gas. The developments of insulation design for LPG/LNG tanks and storages have consequently been continued. Besides the different processing methods of pouring and spraying polyurethane,
Foam glass and mineral wool have been included into the designs. Meanwhile, over 20 tanks of various sizes – (7 LPG and 5 LNG Plants) have been insulated by Nas Trust Corp.
- FUEL/GAS DEPTS.
The economy of oil and gas storage is always of great importance for refineries and other petrochemical plants. 10 year ago, Nas Trust Corp. developed an automatic spraying system for spraying a thermal or cold insulation cover of rigid Polyurethane foam on the tank shells and pipes.
On L.P.G tanks, either single or double wall, Nas Trust Corp. has successfully applied a multilayer Polyurethane pouring system. Polyurethane foam would be poured in maximum 250 mm high layers as free rise foam behind the external cladding finish. The cladding is fastened onto an iron support construction. To avoid any deformation of the cladding during construction the sheets are also supported by temporary bands which are removed following completion.
COATINGS & LINING
CORROSION CONTROL – COATING & LININGS
Painting and coating systems in all industrial and civil environments play a major roll toward corrosion prevention. The selection of coatings and their application is of vital importance given the many different substrates to be protected and their various operating conditions.
Nas Trust Corp. can offer a full coating service of new construction projects and to maintenance of operational plant. Painting and coating works can also be undertaken at our facility within the Jubail Industrial area. Here we carry out the various critical.
