PRESSURE VESSELS

BEV undertakes design, detailed engineering, manufacture, testing, certification and code stamping of pressure vessels to ASME Sec VIII Div 1, Div 2, BS 5500, IS 2825, AD 2000-Merkblatt etc. BEV holds ASME ‘U’ and U2 Stamps for manufacture and National Board ‘R’ Stamp for repair and recertification. BEV is also authorized by the National Board to use ‘NB’ Stamp. The plant is also approved for manufacture of pressure vessels under the rules of AD 2000-Merkblatt HP0 / EN ISO 3834-2 / PED 97-23-EC by TUV-Nord Systems GmbH. It is also approved under PED 97/23/EC Module H1 by Hartford Steam Boiler International GmbH. Pressure vessels for various applications such as air receivers, columns, reactors, towers, digesters, pig launchers - receivers etc. can be manufactured and / or repaired. Also, pressure vessels under Indian Boiler Regulations, 1950 such as boiler steam / mud drums, blow down tanks, HP Heaters, Deaerators, headers for various applications such as waterwall headers, economizer / superheater / reheater headers etc. can be manufactured and IBR stamped.

We also manufacture pressurized transportable tanks for hazardous chemicals with Code Stamp, PED certification and IMDG, ADR, RID, US DOT, UK DfT certification.

 

BEV has a team of competent design engineers, design associates and draftsmen experienced in the field. 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 etc. can also be carried out by our design associates. In case process design or design of vessel internals is required, we can establish arrangements with well known European engineering companies operating from India or Europe.

 

Materials of construction range from carbon steel, alloy steel through stainless steel including SMO (6% Mo) and Duplex / Super Duplex Stainless Steel and exotics such as Incolloy, Hastelloy, Monel, CuNi, Titanium 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 100 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.

 

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. Semi automatic and manual FCAW is used for welding of saddles, supports and stiffeners.

 

Hydro testing up to 600 bar can be done with or without chart recorders. Pneumatic testing and / or helium leak testing could also be done.

 

For ASME Code Stamped jobs, we have an Authorised Inspection Services Agreement with Hartford Steam Boiler Inspection and Insurance Company of Connecticut. Hartford Steam Boiler International GmbH is the Notified Body for PED certification jobs. We also have a second AIA services agreement with Lloyds Insurance Inc. For special certification requirements such as US DOT, ADR, RID, UK DfT, IMDG etc., we engage Lloyds Register Verification Ltd. as the certification body. GOST-R certification of pressure vessels for Russia or GOST-K certification for Kazakhstan can also be arranged through duly accredited certification bodies.

 

Country specific compliance certification such as that for Malaysia, Singapore, Australia etc. can also be arranged through authorized third party inspection agencies such as Bureau Veritas. This would facilitate seamless integration of our pressure vessels into the project in the country of installation.

 

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. All our WPQRs are witnessed and certified by third party inspection agencies such as Bureau Veritas, TUV Nord etc. Welders could also be qualified in presence of third party inspection agencies if it is a requirement. If Client requires us to appoint an independent third party inspection or certification agency, it could be arranged.

 

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. If rubber / PTFE / PPE lining is required for pressure vessels, these could be arranged through specialist subcontractors. Non destructive testing such as radiography, ultrasound etc. and material testing at NABL accredited testing facility is available within reach.

 

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 pressure vessel projects recently executed / in progress, click here.
