BEV undertakes design, manufacture, testing, certification and code stamping of shell and tube heat exchangers, air cooled heat exchangers, air cooled condensers etc. to ASME Sec VIII Div 1, TEMA, API 660 / API 661. Also we design and manufacture plate fin heat exchangers such as steam coil air preheaters. Various applications include process gas coolers, lub oil coolers, HP / LP Heaters, Condensers etc. to customer specifications. BEV holds ASME ‘U’ and U2 Stamps and National Board ‘NB’ and ‘R’ Stamps. The plant is approved by Hartford Steam Boiler UK Ltd. (Notified Body) for manufacture of pressure vessels under Pressure Equipment Directive PED 2014/68/EU of the European Union, Module H1 and H. BEV is also authorized by TUV Rheinland to manufacture pressure vessels under AD 2000 Merkblatt Module HP0. Heat exchangers for steam related application such as HP Heaters can be manufactured under IBR Stamp.
BEV has a team of competent design engineers, design associates and draftsmen experienced in the field. Thermal design of heat exchangers can be performed using either proprietary software like HTRI or custom developed spread sheets. Generally PV Elite supplemented with custom developed spread sheets is used for mechanical design and latest version of Autocad for drafting. Finite element analysis, stress analysis, vibration analysis etc. can also be carried out by our design associates.
Materials of construction range from carbon steel through stainless steel including exotic metals like SMO (6% Mo), Duplex/Super Duplex Stainless Steel, Hastelloy, Inconel, Incolloy, Titanium, Cu Ni etc. For material preparation, we have a CNC profile cutter with plasma and oxy fuel torches. We can roll shells up to 85 mm thick and 3.2 M wide. Cold working is maximized with CNC band saw, Universal Steel Worker etc.
We have a wide range of welding manipulators such as column and boom 4 M x 7 M, heavy duty rotators up to 50 tons and positioners up to 3 tons. We have the entire range of welding gear viz., SAW, SMAW, GTAW and FCAW welding machines. We also have BugO Speed Weaver welding oscillator for GTAW / FCAW and custom developed jigs for tube to tube sheet welding. There are also baking and holding ovens for welding electrodes and flux, apart from portable quivers for welders and welding operators. For stainless steel and exotics, there is a purpose built, segregated area.
We have a well equipped machine shop with a 3 Axis CNC Vertical Machining Centre Hartford PRO 3210 imported from Taiwan with bed size 3150 mm x 2100 mm with 70 bar through coolant BT50, 6000 rpm spindle, 20 tools ATC, right angle milling head and Fanuc controller. Tube sheets and baffle plates drilling, facing and gasket grooving can be accomplished with high precision and minimum turnaround time. We also undertake job work on tube sheets and baffle plates. The machine shop also has a radial drill and 3 gap bed centre lathes. Exotic metals are handled using stringent material control and handling procedures and work is carried out in controlled environment. We carry out post weld heat treatment / stress relieving in temporary purpose built temporary furnaces within our facility or in gas fired furnaces at a specialist subcontractor’s premises of pressure vessels. Semi automatic and manual FCAW is used for welding of saddles, supports and stiffeners.
