DOLPHIN carries out Mechanical Design and detailed fabrication
drawings of Shell & Tube Heat Exchangers as per ASME Sec.VIII Div.I & TEMA. We use mechanical design software, which produce complex designs for various operating conditions and come up with most optimum solutions.

Shell&Tube

All fabrication drawings are generated on drawing software. Fabrication facilities include CNC Drilling (for Tube Sheet Drilling), Orbital Welding Machine (for Tube to Tube Sheet Welding) & Microprocessor based Telescopic Expansion Machine ( for Tube to Tube Sheet Expansion) in addition to the regular machines like Plate Bending, TIG / ARC Welding, Grinding, Plasma Cutting etc. A full range of vertical and horizontally mounted heat exchangers is used in industries ranging from Chemical Plants and Paper Mills to Oil Refineries and offshore platforms. Customer’s specific thermal, mechanical and dimensional requirements are met with capacity of upto 400 bar g pressure and temperature of upto 1000ºC supplied with full certification as per TEMA(Class R,C,B) ASME Sec. VIII Div.1, BS, DIN Standards.
