Tube Trimming & Tube to Tube sheet Expansion :-
We also do Tube Trimming & Tube to Tube sheet Expansion for all our Equipments having such requirements.
Our Expansion technicians have specific hands on experience for various materials like CS, SS, Duplex, Brass, Alloy, Cu Ni.
We have Electronic Torque Control Expansion Machines with Heavy Duty Expansion Drive Sets and Specially manufactured Tube Expander & Mandrels to do expansion as per Thinning Percentage.
Our Trained & Skilled Engineers have hands on experience to Inspect Expanded Tube Joints & provide Training & Guidance to technicians to handle Expansion for varied materials.
Stacked Exchangers :-
We have manufactured Stacked Exchangers for Refinery Applications. We have hands on experience to work on Connecting Stacked Shell & Channel Nozzle Fabrication Tolerances.
We generally have carried out Hydro test for Exchangers in Stacked Condition and in Dis Assembled Conditions.
Heat Exchanger Tube Bundles :-
On Specific Requirements of Customers we can manufacture Only Heat Exchanger Tube Bundles.
We understand the importance of close Tolerances to be maintained for Tube Bundle Diameter & and Exchanger Shell Inside Dimensions. Years of experience has helped us to master the Bundle Insertion Technique.
