High
Pressure Spheres
VTV's
credentials in the design and construction of spherical tanks
include more than 250 Pressurised and cryogenic spheres for LPG,
ethylene, C2C3, propane, butane, nitrogen, LoX, LiN, hydrogen,
inert gas and ammonia service in India & abroad since 1964.
This performance slots it amongst the leading sphere manufacturers
in the world.
VTV has pioneered the design and construction of pressure spheres
in India and Continues to drive international spherical tank technology
through the creation of patented construction processes and use
of computer simulation tools to arrive at more economical sphere
designs. VTV spheres are designed to provide superior levels of
integrity, economy and safety through the application of well-researched
petal fabrication technologies.
VTV's 'Varaha sphere' is constructed by a unique patented process
involving the phased tier wise construction of the tank from top
downwards to enable construction work to proceed as close to grade
levels as possible. This system has merited the appreciation of
clients, consultants and third party inspection agencies and underlines
VTV's commitment towards continual evolution and improvement.
VTV has inhouse capability for field stress relieving of large
spherical tanks. VTV owns mobile stress relieving units with automated
controls to help provide a well controlled heat treatment operation.
VTV's bank of heavy duty hydraulic presses are capable of cold
pressing plates upto 85 mm thick. VTV's mobile fabrication gantry
systems equipped with hydraulic press facilities, prepinching
and plate bending machines, EOTs form 7.5 Mt. to 15Mt. capacities
and all residual equipment are mobilized for the field fabrication
of large spherical tank installations.
