Stainless Steel & Exotic Material Welding
FAQ
What materials does MPF Engineering specialise in welding and fabrication?
MPF Engineering specialises in stainless steel and exotic materials, including austenitic stainless steels, duplex grades, and titanium. We undertake both lightweight and heavy plate fabrication, delivering components, pipework, vessels, and equipment for demanding industrial and process applications.
Can MPF Engineering fabricate pressure equipment and critical components?
Yes. We have extensive experience manufacturing pressure vessels, storage tanks, pipework, heat exchangers, and condensers. Fabrication is completed in accordance with applicable standards, including ASME, API, and AS requirements, and supported by approved procedures and comprehensive quality assurance processes.
How do you ensure quality and compliance when working with exotic materials?
All exotic material welding is carried out by qualified personnel using approved welding procedures. Projects are supported by Inspection and Test Plans (ITPs), weld traceability, and Non-Destructive Testing (NDT) where required, ensuring consistent quality and full compliance with project specifications and industry standards.
Do you support food-grade and hygienic stainless steel applications?
Yes. MPF Engineering has strong capability in food-grade and hygienic stainless steel fabrication, including dairy tube and process pipework. Our work is carried out to hygienic design principles and relevant standards, making it suitable for food production, beverage, and pharmaceutical environments.
Stainless Steel & Exotic Materials Fabrication
MPF Engineering delivers high-integrity fabrication and welding across stainless steel and exotic alloys, applying current best-practice methods to projects where weld quality is non-negotiable.
From light gauge hygienic tube through to heavy plate pressure work, we manufacture components, equipment, and piping systems that perform in the most demanding process environments in New Zealand — dairy and food production, chemical processing, geothermal, and power generation.
Our material capability spans the full austenitic range, duplex and super duplex grades, and titanium — backed by qualified welding procedures and tradespeople ticketed to the relevant codes.
Whether the job calls for a mirror-polished food-grade finish or a code-stamped pressure vessel destined for a corrosive service, the discipline is the same: get it right at the bench, prove it through the QA system, and hand it over with full traceability.
Proven Quality & Code Compliance
Our engineers and tradespeople have delivered complex fabrications including condensers, heat exchangers, pressure vessels, large-diameter pipework, conveyors, and storage tanks for some of New Zealand's most demanding process operators.
Every project is run under a robust Quality Assurance system covering material traceability, weld procedure qualification, NDT, and final documentation — so what leaves our workshop is compliant, certified, and ready for service.
