Vi Energ resources private limited is involved in Design and Manufacturing of shell & tube heat exchangers including supply of all spares, documentation as per the client technical specification.

ENGINEERING / DESIGN The scope includes all the engineering works including but not limited to the following:

Design, fabrication & supply of shell & tube heat exchangers including tubesheet, tube bundle, body flanges, nozzles, lifting lugs to facilitate erection of shell & tube heat exchangers external /internal supports.

WRC calculations for welded attachments like nozzles, lifting lugs, leg supports, saddle supports etc. Detailed fabrication drawings including tube bundle, body flanges, nozzles, insulation cleats, lifting lugs, earthing cleats, expansion below (if needed), name plate & name plate bracket, support legs, saddle supports etc.

Supply of test rings required for hydrotest , Earth cleats (minimum 2 nos.) , Surfaces preparations and painting of equipment as per MDS, Work inspection, testing and certification, Obtaining ASME U approval from authorised Inspector.

Quality assurance, quality control, quality plan, inspection

The shape of dished end and overall height will be as per mechanical data sheet. Minimum thickness of shell and dished end will be achieved taking into account of thinning, forming etc. Wherever hot forming and subsequent heat treatment is involved, Our adopted procedure will not impair the mechanical properties of the material beyond the limits specified in respective material specification/ codes & standards.

For U-tube heat exchangers, our Quality will ensure thickness of tube must be uniform at bending area also.

For floating type heat exchangers, where removable type tube bundle, Our Quality will ensure the free movement of tube bundle during removal & fixing of the same.

Vi Energ will perform Mock-up test for tube to tubesheet joint.
