Product Description


Heat transfer in agitated vessels can be carried out either through an external jacket on the vessel or by internal coils. Where a jacket or coils cannot provide the surface area required, a recirculation loop with an external heat exchanger may be used.

Advantages of Half Pipe Reactors in High Pressure Service

Dec 01, 2020 · Dimpled jackets are often ideal for smaller vessels in lower pressure environments, but the numerous welds on this type of reactor jacket can be Development and Field Trial of Dimpled-Tube Technology Oct 12, 2006 · GTI has identified an approach that will increase heat transfer rates without a significant increase in pressure drop or fouling rate. Compared to other types of heat transfer enhancement approaches, the proposed dimpled tube approach achieves very high heat transfer rates at the lowest pressure

Dimple Jacket Fabrications & Welding. CMPI provided mechanical dimple jackets are sheets of metal with equally spaced depressions, or dimples, pressed into the metal to provide contact points for welding to a base, such as a tank or pressure vessel. We can easily attach dimpled sheets to the outside of your fabrications to optimize media flow.

Dimple Jacketed Vessels - Thomasnet

Manufacturer of dimple jacketed pressure vessels including special heat exchanger tanks. Dimpled heat transfer pressure vessels are available in volumes ranging from 2 gal. to 300 gal. with OD ranging from 9 in. to 36 in. Features include Thermolux paint & chloride-free Four Ways To Heat and Cool a Pressure Vessel - Central Apr 14, 2019 · The jacket has punched areas of dimpled stainless steel (called dimples) which assist with the heat or cooling transfer of the fluid. The dimple jacket heat transfer process or cooling process, can be used to heat or cool the contents of the pressure vessel or the storage tank. 2. Clamp-On Jackets.

Nov 08, 2010 · The dimple jackets are generally limited to 300 psig design pressure while half-coil jackets can be used up to a design pressure of 750 psig. For half-pipe coil jacket, the higher heat flux rate may require multiple sections of jackets to avoid having condensate covering too much of the heat transfer Jacketed Vessel Heat TransferJacketed Vessel Heat Transfer Calculation estimates overall heat transfer coefficient for a vessel with an agitator along with heating/cooling medium flowing in jacket, spiral jacket or half pipe coil.

Dec 05, 2011 · If a dimple jacket is clamped onto an existing vessel and adhered with heat transfer mastic, theoverall heat transfer coefficient of the system will be very low. Mastic is used to try to minimize air pocket resistances between the vesselwall and the jacket. Historically, this arrangement results in poor heat transfer.
