Petrochemical and Process Equipment
Reactors, columns and exchangers in process plant see acid, chloride and high temperature service, often all in the same vessel. Nickel alloy filler metals carry the corrosion performance the base metal promises.
Pain points
What Makes Consumable Selection Hard Here
- Pitting and crevice corrosion resistance across the weld and the heat affected zone
- Dissimilar metal joints between stainless, nickel alloy and carbon steel
- High temperature oxidation and carburisation resistance in furnace equipment
- Repair and maintenance welding during short shutdown windows

Petrochemical and Process Equipment Questions
Which AKWELD grades are used in petrochemical and process equipment?
Grades such as ERNiCrMo-3, ENiCrFe-4, ERNiCrFe-5 are the usual starting point. The exact choice depends on the base metal, the code and the service temperature.
Do you supply the data our inspector will ask for?
Each grade page publishes the classifications and chemical composition, plus mechanical properties where the factory datasheet gives them. Ask us for the test record for a specific batch.
Can you help with consumable selection for a specific project?
Yes. Send the base metal, the welding process, the position, the service temperature and the code, and our technical team will shortlist the grades that match.
What quantities do you supply for project work?
Project quantities are quoted against the schedule you send. Trial quantities are available first so the grade can be qualified on your own procedure.
Working on a Petrochemical and Process Equipment Project?
Send the base metal, the code and the schedule. We will shortlist the grades and send the data your welding engineer needs.
