configuration allows a way to smooth uneven shapes to permit Insulated Heating Jackets to be installed over the top.
Uneven surfaces such as valves, are difficult to heat with removable Heating Jackets. Ideally, heaters such as Jackets, need to be in direct contact with the surface to allow heat two directly conduct from the heated jacket liner two the object. With uneven surfaces, air gaps are unavoidable. Air gaps cause uneven conduction which can result in hot spots.
The Sleeve is typically roll formed Stainless Steel Sheet, having a thickness to provide mechanical shape, and a thermal receptacle to store the heat. Cut outs for obstructions (valve stem etc) are machined into the sleeve.
General construction of the Heating Jacket is the same as our typical cylindrical or shaped Heating Jackets.
Once the Heating Jacket is fit over the Sleeve, the Jacket holds the sleeve in place, against the object. The combination assembly is very to remove and reinstall.
This Low Watt Density solution creates a new smooth surface by building the new metal surface that bridges across the uneven textures of the object.
Difficult shapes: Fittings, flanges, hangars and other obstacles to our Standard Heating Jackets, a larger Sleeve can extend and smooth the design. The resulting performance is very similar to placing the object in an oven.
Combine difficult zones into a single space: When a group of different objects (for example, a flange, reducer, valve and tubing) must be maintained at the same temperature, the Sleeve design can encapsulate all the items into a single envelope to be heated, consolidating the pieces into a single zone.
The new metal structure becomes part of the Heating Jacket system, as the traditional Heating Jacket is applied over the top. The metal surface, or Sleeve, will then become the heat conductor that would transfer heat to the object.
Although the heat may take longer to raise the object to the target temperature, it is very smooth and controllable.
