Prefabrication & Manufacturing
Globally positioned manufacturing facilities
All workshops are fully equipped with specialised tooling and machinery capable of producing a multitude of different components. Our experienced team of fabricators are competent in the manufacture of both non-pressure and pressure part assemblies.
Multi-discipline Fabrication Workshops
Piping
Avantis offers a comprehensive pipe fabrication and installation service to the marine, offshore and power generation sectors. Our team has the capability to manufacture and install low and high pressure systems using a wide range of materials such as:
- Carbon steels including fine grained steels; ASTM A671 Gr CC60
- Stainless steels grades 304, 316 & 310H
- Aluminium including cryogenic grade 5083
- Exotic materials including inconel, monel, chrome molybdenum, hastelloy,
duplex and super duplex - Composite and plastic materials, ABS, PVC & PVDF
We achieve rigorous manufacturing specifications with the use of post weld heat treatment, painting, galvanizing, radiological testing and hydrostatic testing. This is reflected by our accredited to supply pipework compliant with P.E.D. (Pressure Equipment Directive) and A.S.M.E. (American Society of Mechanical Engineers).
Process Skids
Avantis has the ability to manufacture and deliver package skids designed for numerous applications including but not limited to:
- Temperature swing adsorber TSA
- Vacuum swing adsorber VSA
- Cryogenic injection skids, Liquid nitrogen and Liquid oxygen
- Lean meg injection
- LIN and LOX pump skid boxes
- PSA skids
- Pump skids
- Metering skids including O2
- Hydrogen recovery skids
- LNG pump skids for marine applications
Pressure Vessels
Our workshops specialise in the manufacture of pressure components for boilers using fully traceable and certified materials. This includes manufacturing headers, steam and water drums with the addition of tube manipulation of superheater, generation bank, screen and waterwall elements.
Our capabilities in boiler assemble manufacture is also matched by our ability to manufacture heat exchangers and condensers Our workshops can manufacture and repair the following types:
- Main condensers
- Auxiliary condensers
- Feed heaters
- Cargo heaters
- Jacket water cooler
- Oil coolers
Non-Destructive Testing
Avantis employs a selection of NDT techniques during and after all fabrication works. These include:
- Eddy-current testing
- Dye-penetrant Testing
- Hydrostatoc Testing
- Ultrasonic Testing (UT)
- Radiography Testing (RT)
- Leak Testing (LT)
- Magnetic particle testing
