Storage Tanks

BEV undertakes design, manufacture and testing of vertical as well as horizontal storage tanks for various applications such as hydro carbons, potable water, fire water, effluent treatment, process chemicals storage etc. These could be designed and manufactured to API 650, BS 2594, EN 12285 etc.

 

BEV has a team of competent design engineers, design associates and draftsmen experienced in the field. Generally custom developed spread sheets is used for mechanical design and Autocad for drafting.

 

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 an extensive range of WPQRs to ASME Sec IX and EN ISO 15614 covering a wide range of materials, thicknesses, processes and other variables. 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. 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 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. 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 build temporary furnaces for post weld heat treatment / stress relieving of complete tanks. For local stress relieving such as for access hatch, resistance heating is used. BEV has the paraphernalia for vacuum testing, helium leak testing etc.

 

We have a totally enclosed steel grit blasting facility complying with Euro III norms imported from Hodge Clemco, UK. Its size is 16M (L) x 8 M (W) x 5 M (H). Items bigger than this are blasted under custom built canopies using 200 litres blast pots and copper slag as abrasive medium. Painting facility is fully equipped with air less spray painting machine as well as cup guns. Special erosion resistant internal coatings can be applied using Belzona or Ceramkote products. Non destructive testing such as radiography, ultrasound etc. and material testing at NABL accredited testing facility is available within reach. If tank calibration is required for custody transfer or tariff metering purposes, it could be arranged from approved agencies.

 

Management team has extensive experience in the heavy engineering industry within and outside India, especially with multi national companies, EPC global contractors, service providers etc. We have competent QC Inspectors, AWS/CSWIP 3.1/3.2 Certified Welding Inspectors, API 510 Pressure Vessel Inspectors and BGAS Grade II Painting Inspectors. In short, you are assured of a truly world class service within India. For a list of storage tanks projects recently executed / in progress, click here.
