We begin with updating you with pleasure that our workshop has been revalidated and approved for FABRICATION of CRYOGENIC & NON-CRYOGENIC PRESSURE VESSELS under STATIC & MOBILE PRESSURE VESSELS (UNFIRED) RULES 2016, up till 31.12.2025. The order is attached for you to read.

We have been constructing capacious STORAGE TANKS since 1985, – for storing various Chemicals or finished Products, by the way more for Petroleum Products and Fire Water and constructed in various materials (CS, several grades of Stainless Steel), first constructing on behalf of principals holding license to undertake construction of Storage Tanks, and later as an authorized Constructor under 
 P E S O (Petroleum and Explosives Safety Organization)

We have acquired our registration with The Chief Controller of Explosives way back in 1998 and making it permanent the next year in 1999. All our constructions are performing fine without any complaint of defective work or malfunctioning, as on date.

We construct Storage Tanks conforming more to the engineering codes prescribed in API 650 and others as preferred by Clients and Engineering Consultants; including indigenous INDIAN STANDARDS

We as an authorised Constructor under P E S O have constructed and supplied UNDERGROUND TANKs of different capacities to store Petroleum Products like Motor Spirit and Diesel more for Bharat Petroleum Corporation.

We have also Designed, Fabricated and Supplied EVACUATION VESSELS, KNOCKOUT DRUMS and AIR RECEIVERS to numerous LPG BOTTLING PLANTS of different Oil Companies namely all over our country. The word STORAGE TANKS might read simple and perhaps draw no serious attention.

Incidentally, STORAGE TANKs that would store in bulk any kind of product that could activate any type of hazards – (Fire / Explosion / resultant severe land damages / Floods) – do come under Petroleum and Explosives Safety Organization (formerly Chief Controller of Explosives) and the law holds beginning from its designing conforming to the required engineering and technical codes. Therefore, any contractor interested to directly undertake the construction of Storage Tanks needs to acquire an authorization from P E S O.

Incidentally, the old method of construction consisted of building one shell of the Storage Tank on the already laid Bottom Plate placed on the Bitumen topped Civil Pad Foundation, beginning with the bottom shell one on the other after completing all welding – between each Shell Portion forming a full Shell, Shell to the Bottom Plate and Shell to Shell – and finally taking up building the roof along with the rafters and as per the Design & Detailing to that particular Storage Tank.

The present method that is adapted by all is first constructing the top two or more shells totalling for a minimum of 3 Meters height and then to construct the roof, jack them up to continue with the other shells towards bottom. Fully cylindrically formed matching with the designed diameter and completely Welded Shells are jacked (with special purpose hydraulic Jacks placing them in equal distances of the perimeter of the Storage Tank and as many depending on the length of the perimeter) to construct the shells in a descending order from the top and with the bottom shell for building last.

Construction by Jacking Method reduce the tensions of maintaining the Safety, Health and Environment factors as the workers shall work at a low and safe height though all the safety equipment in place; and the fumes from welding shall just fly to the top of the construction.

These are in addition to the time saved by lesser physical mobility of the workforce to enter or come out from the bottom during work. The bottom plate also can be kept neat with regular picking of debris and sweeping during the construction; as well psychologically sustain the morale of the workers at a high as functioning in a clean environment.
