Cladded Vessels & Reactors
Alok Equipments manufactures clad reactors and cladded vessels, pairing a corrosion-resistant alloy lining with a carbon or stainless steel shell for severe process duties.
Cladding gives the corrosion resistance of titanium or Hastelloy at a fraction of the cost of a solid-alloy vessel. We build explosion-bonded clad reactors and vessels, with jackets, limpet coils and agitators.
Clad and lining materials include titanium, Hastelloy C22 and Hastelloy C276, on carbon steel or stainless steel backing plate.
Typical duties are corrosive reactions in chemical, petrochemical, agrochemical and pharmaceutical plants, where chlorides or acids rule out standard stainless steel.
Clad bond integrity is verified by ultrasonic (UT) scanning. Reactors are supplied with agitator, drive and mechanical seal, and the agitators are designed and built in-house.
Recent builds include a 5 m³ clad reactor in titanium, a 16 KL cladded reactor in Hastelloy, 5 KL reactors in Hastelloy C276 and clad reactors in Hastelloy C22.

Questions buyers ask
What is a clad reactor, and why choose one over solid alloy?
A clad reactor has a corrosion-resistant layer, such as titanium or Hastelloy, explosion-bonded to a carbon or stainless steel shell. It handles the same corrosive duty as a solid-alloy vessel at a fraction of the cost. Alok Equipments builds them in Pune.
Which clad materials do you work with?
Titanium, Hastelloy C22 and Hastelloy C276, on carbon steel or stainless steel backing plate, with clad plate to ASME SA-264, SA-265 and SB-898.
How large can your clad reactors be?
Up to 50 KL, with clad plate up to 45 mm thick (backing plus clad) and design pressure up to 20 bar(g).
Do you supply the agitator, and how is the cladding checked?
Yes. Reactors are supplied with agitator, drive and mechanical seal, and the agitator is designed and built in-house. Clad bond integrity is verified by ultrasonic (UT) scanning.
