Fabrication of High Purity Process Pipework consists of the cutting and welding of high-alloy and stainless-steel material used for clean fluid handling in select industries such as Semiconductor, Pharmaceutical, Bio-Technology and Research Laboratories.
In the welding phases of High Purity Process Pipework, welding is characterised by the need for accurate, strong welds that are deficient of any defects such as voids, cracks, pits or discoloration, outside and inside the tube. Traceability and repeatability are prime requirements of process piping welds. High purity welding is undertaken in a cleanroom setting where there is a controlled environment, preventing fewer contaminants from entering the weld area. This is crucial as the gases or fluids going through the tubing need to remain very clean.
Although high purity welding is ideal for any industry, there are certain industries in which high purity welding is necessary due to the applications for which the metal tubing is being fabricated. The semiconductor, medical device and aerospace industries are the most common industries requiring high purity welds.
High-purity welding has universal application across a number of industries and sectors. One example includes the aerospace industry, with welded components experiencing high levels of stress, it is important that high purity and integrity is achieved, often through orbital welding techniques. In the nuclear industry, titanium is often used in nuclear piping due to its improved resistance to corrosion from seawater; titanium is welded in cleanroom environments with argon to avoid oxidation, this helps to preserve the natural strength of the titanium. Finally, high-quality welds are vital in the food production industry to prevent contamination through bacteria. Smooth welds prevent the creation of occlusions which create environments that harmful bacteria can establish and colonise within; this can be achieved through treating the backside and frontside of the weld with equal amounts of oxygen.
Orbital Fabrications highly-skilled installation team provides solutions for the orbital welding of internal piping and a large number of ultra-modern welding stations, portable and fixed orbital welding machines. Our pipework team is available to undertake any installation assignment including undertaking pipework installations as a stand-alone service or within a managed project in our turnkey service; eliminating the need for a separate contractor company.
Our fabricators and engineers are highly-skilled in all aspects of high purity process pipework installation. Working with a diverse range of materials, we can provide solutions for stainless steel and specialised high-nickel piping materials. Our fabricators and welders assemble your pipework to your exact requirements to guarantee joint integrity and quality of installation to provide peace of mind.
Orbital Fabrications is well-suited for the in-house fabrication of all high purity process pipework in its state-of-the-art, ISO certified in-house class 5 & 6 cleanroom facility. This ensures the highest level of cleanliness and no contaminants, with all products individually bagged and sealed ready for installation in the same condition it leaves the clean room.
