CAPABULITY  OF WORK

​

• Sandhya Tube Heat Exchanger for various industrial application like heating, cooling, condensing and reboiling

• We Design & Engineering  units presently to working pressure of 80 bar for process / service plant and with -196 C temperature upto 400 C. For specific design we can manufacture units with 150 bar pressure at 500 C. 

​

• Our Design & Engineering  facility is equipped to fabricate STHE with diameter of 2000 mm and tube length upto 9000 mm. For special equipment we can make heat exchanger with 12000 mm tube length

​

• We design STHE with or without ASME 'U' stamp certification, CE certification and others codes.

​

• Heat exchangers are manufactured with carbon steel or Stainless Steel AISI 304/316, depending upon the application. Material like SS304L, SS316L, Hastelloy, Copper, Cu-Ni alloys, Titanium, AL6XN can also be offered.

​

 COST SAVING From estimating , our Design Engineers  & Draftsman designs are created to efficient fabrication, which saves customers on material cost and manufacturing time. 

​

Quality Drawings : We generate high quality fabrication  drawings for every  project, which results in consistent of quality delivered to customers.

​

Project Efficiency: Working with our  Managers and design team  allows Riggins to select the best materials and best methods for fabrication. result  quality fabrications, delivered on-time.

​

On-Time Delivery:  we live it daily, With the fabrication process in mind during the design stage we are able to avoid delays at the build stage. Fabrication  heat exchangers requires tight machining tolerances and welds that must conform exactly to approved welding procedures

​

Materials of Construction, Sandhya consultancy  Design for weld procedures cover all  wide variety of metals such as  stainless steel, Duplex stainless steel, copper alloys, Copper Nickel (CuNi), Inconel, Monel, Haynes Alloys, titanium, and other exotic alloys.
