Corrosion is one of the biggest concerns when operating pressure vessels in chemical, petrochemical, fertilizer, and refinery environments. Instead of switching to fully exotic alloy vessels — which can be extremely expensive — many companies now rely on clad pressure vessels. This is an area where a capable pressure vessel manufacturer in India can help companies significantly reduce both cost and long-term risk.
What Are Clad Pressure Vessels?
A clad vessel uses two different metals bonded together:
- Carbon steel (base material) for mechanical strength
- A corrosion-resistant alloy (cladding layer) such as SS316L, Inconel, Monel, or Hastelloy
This combination delivers the performance of a high-alloy vessel at a much more economical price.
Why More Industries Are Choosing Cladding
- Major Cost Savings
Exotic alloys like Hastelloy or titanium are expensive. Cladding limits their use to the areas directly exposed to corrosive chemicals, reducing cost dramatically.
- Improved Corrosion Resistance
Clad vessels are ideal for processes involving acids, solvents, chlorides, and high-temperature environments. They ensure long-term durability while maintaining product purity.
- Mechanical Strength + Corrosion Protection
The carbon steel base handles high pressure and temperature, while the alloy layer protects the vessel from corrosion — offering the best of both worlds.
- Longer Equipment Life
Clad vessels generally last longer, require less maintenance, and reduce downtime — which is crucial for continuous process plants.
Where Clad Vessels Are Used?
- Chemical reactors and storage
- Petrochemical units
- Fertilizers and refineries
- Pharma and biotech
- Power plants
- Water treatment
Why Work With an Experienced Manufacturer
- High-quality cladding requires:
- ASME Section VIII-compliant fabrication
- Correct cladding thickness
- Skilled weld overlay or explosion bonding
- NDT and hydro testing
- Full traceability and documentation
A knowledgeable pressure vessel manufacturer in India ensures the vessel performs safely under demanding conditions.
Final Thoughts
Clad pressure vessels offer a smart balance of performance, reliability, and cost — making them a top choice for industries facing corrosive processes. With strong fabrication expertise and improved technology, Indian manufacturers are delivering solutions that meet global standards.
