Pressure Vessels
Pressure Vessels We are involved in producing a comprehensive range of Pressure
Vessels. A pressure vessel is a closed container designed to hold gases or liquids
at a pressure substantially different from the ambient pressure. Pressure vessels
are an inseparable part of the process industry. Many critical reactions need to
be carried out in closed vessels at elevated pressures and temperatures. Some reactions
can be explosive in nature. We carefully design and manufacture these vessels to
handle such extreme conditions of temperature and pressure. We produce all kind
of Carbon Steel and Stainless steel Pressure Vessels as per clients' requirements.
Features
- Hold pressure at extreme
- Handle high risk tasks
- Maximum safe operating pressure and temperature
- Good heat resistance
- Corrosion resistant
- High wear resistance
- High tensile strength
- Resist maximum stress
Applications
Pressure vessels are used in a variety of applications in both industry and the private sector.
- Industrial compressed air receivers
- Domestic hot water storage tanks
- Diving cylinder
- Recompression chamber
- Distillation towers
- Autoclaves
- Vessels in mining or oil refineries and petrochemical plants, nuclear reactor vessel
- Habitat of a space ship
- Habitat of a submarine
- Pneumatic reservoir
- Hydraulic reservoir under pressure
- Rail vehicle airbrake reservoir
- Road vehicle airbrake reservoir
- Storage vessels for liquified gases such as ammonia, chlorine, propane, butane, and LPG.
Technical Specifications
Maximum operating temperature :
Up to 300° F(149° C), depending on pressure, vessel size and type of stainless
(see table below). Models with neoprene base should not be exposed to high temperatures
for long periods of time.
Note : O-rings containing silicone
rubber should not be operated extensively at temperatures over 250° F (121°
C).
Maximum Operating Pressure :
The maximum pressure at 100° C is engraved on a permanent plate on the side
of the vessel. At higher temperatures the maximum operating pressure is decreased
(see table below). Optional relief valve set to 100 psi (7 bar).
Low Positive Pressure : A pressure
of 15 psi (1.0 bar) or greater should be sufficient to seal the pressure vessel
under most conditions. However, the optional vacuum closure may be required at pressures
under 30 psi (2.1 bar) if operating at low temperatures or with the stiffer types
of O-rings such as Viton.
Negative Pressure (Vacuum): The optional vacuum closure adapter is required
to seal vessel when working with negative pressure. Maximum negative pressure with
optional vacuum closure, 29 in Hg (1.0 bar).
