Description
Vessels: From 50 Litres to 180,000 Litres that can be used for various industrial applications, with the following accessories/attachments.
- Jacket is used for heating or chilling or maintaining the product temperature within the vessel
- Product temperatures can be maintained with Electrical trace heating of the vessel
- Product internal temperatures can be maintained by cladding in either stainless steel (welded or riveted) or riveted aluminium
- Attaching a mixer/high shear blending unit to the vessel
- Ensuring that the vessel is suitable for CIP, including spray balls etc.
New vessels are designed as per the industry standards – like ASME VIII
Div 1 and Good Engineering Practices – are documented and followed for quality assurance system to ensure that the final product reflects the client’s expected parameters and is of best quality.
We supply a documentation that includes
- Manufacturing methods,
- Raw material certificates
- Outside inspection, where applicable.
Conventional Jackets
- A second shell is installed over some parts of the vessel, creates an annular space within that cooling or heating medium flows.
- A simple conventional jacket without internal components is ideally very inefficient for transfer of heat, because of extreme low velocity of the flow media resulting in a low heat transfer coefficient.
- Condensing media: such as Steam/Dowtherm A is an exception as for this case the heat transfer coefficient is not depending on velocity or turbulence, but it is related to the surface area upon that the media condenses and the efficiency of removing condensate.
- Internals include baffles that direct flow in a spiral pattern around the jacket, and agitating nozzles that cause high turbulence at the point where the fluid is introduced into the jacket.
Half-Pipe Coil Jackets
Pipes are split lengthwise, usually with an included angle of 180 degrees (split evenly down the middle) or 120 degrees, then wound around the vessel and welded in place.
Dimple Jackets.
- A thin external shell is affixed to the vessel shell with spot welds located in a regular pattern, often about 50 mm on centre both horizontally and vertically.
- These so-called dimples impart turbulence to the heating or cooling media as it flows through the jacket.
Plate Coils –
- Plate coils are very similar to dimple jackets, but fabricated separately as fully contained jackets that are then strapped to a vessel.
- Plate Coils are bit less effective than dimple jackets because there is a double layer of metal for the heat to traverse (the plate coil inside surface and the vessel shell).
- They also require good bonding to the vessel jacket, to prevent an insulating gap between the plate coil and the vessel.
- Jackets can be applied to the entire surface of a vessel or just a portion of it.
- For a vertical vessel, the top head is typically left unjacketed.
- Jackets can be divided into zones, to divide the flow of the heating or cooling medium.
Advantages
Jacketed Vessels Advantages include:
- Ability to direct flow to certain portions of the jacket, such as only the bottom head when minimal heating or cooling is needed
- The entire jacket when maximum heating or cooling is required;
- Ability to provide a higher volume of flow overall (zones are piped in parallel) because the pressure drop through a zone is lower than if the entire jacket is a single zone.
- We manufacture vessels used in industries such as brewing, pharmaceutical, chemical and food, so our stock range will suit most customer requirements. Different types of storage vessels:-
- Bulk storage vessels (stainless steel / mild steel)
- Fermentation vessels
- Bright beer tanks
- Cellar tanks
- Brew houses
- Mixing vessels
- Powder silos
- Process vessels
- Micro breweries
- Horizontal vessels
Storage vessels/tanks are used to store liquids, solutions/pharmaceutical raw material and any other chemicals. Storage tanks are simple vessels. These are general purpose vessels made of stainless steel, titanium, fibre glass, galvanized steel etc. and applied by a various industries to store different substances and solutions.
Storage tanks/vessels are available either in horizontal or vertical orientation. Horizontal storage vessel is mounted on stands/saddles and has an access port either at bottom/top. Vertical storage tanks are mounted vertically with access ports at bottom. These tanks are either to be placed above the ground or underground depends on the construction of the storage facility.
The wall thickness of these tanks/vessels determine their application; while single wall storage tanks is used for general application, double walled tanks are used for high pressure considerations.
