DOLPHIN carries out Mechanical Designs, detailed fabrication drawings of Heat Exchangers & Pressure Vessels as per ASME Sec.VIII Div.I & TEMA. We use mechanical design software, which generates complex design for various operating conditions and produces the most optimum solutions. All fabrication drawings are generated on the 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, Tube Finning machine etc. A full range of vertically and horizontally mounted heat exchangers and pressure vessels are used in the industry 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 up to 400 bar g pressure and temperature of up to 1000ºC supplied with full certification, as per TEMA(Class R,C,B) ASME Sec. VIII Div.1, BS, DIN Standards.
