Sizing pipes for superheated steam duty. Superheated steam can be considered as a dry gas and therefore carries no moisture. Consequently there is no chance of pipe erosion due to suspended water droplets, and steam velocities can be as high as 50 to 70 m/s if the pressure drop permits this.

Jacketed piping is required to transport highly viscous fluids having very low flowability. The jackets usually provide temperature to the core pipe so that the flowability of the fluid inside the core is maintained. The jacketed piping system consists of two pipes of different sizes. The larger pipe covers or jackets the smaller size pipe. Jackete...
Jacketed piping consists of four main components. They are: 1. Core Pipe:This central smaller-sized pipe of a jacketed piping system that carries the fluid from one point to the other. 2. Jacket Pipe:This is the larger size pipe that carries superheated steam to maintain the temperature of fluid flowing in the core pipe. 3. Steam Feeder:This is a t...
Depending on the nature of the jacket pipe over the core pipe, two types of Jacketed Piping are found; Continuous jacketing and Discontinuous jacketing. Continuous Jacketing:In this type of piping all piping components including the straight lengths of pipe, fittings, flanges, valves, and branch connections are fully covered by the jacketed pipe. D...
Jacketed piping is not used widely and has got some limited applications. This type of piping is only required where a certain temperature needs to be maintained throughout the transportation of fluid from one point to another. Some of the typical examples of jacketed piping are: 1. To transport molten Sulphur through pipes in a sulphuric acid plan...
Jacketed piping systems are highly complex systems as compared to the usual process piping due to their double-walled piping network. So, these types of piping networks require special consideration during the engineering, designing, and execution phase. Some of the design points are mentioned below: Fluid Pressure:The core pipe will be subjected t...
Jacketed piping requires special stress analysis. Jacketed piping is commonly used to convey very viscous process fluids in an inner pipe, heated by steam/hot water/hot oil or other heating media between the jacket and core pipe. Fig 1 shows the normal components of a jacketed piping system. General Definitions of Jacketed Piping Components for str...
Modeling the Core Pipe:
The core pipe of a jacketed piping system is modeled in Caesar IIas per the below-mentioned steps 1. Do not give pipe insulationthickness while modeling core pipe. 2. The temperature should be the temperature of the process line. 3. Pressure should be the pressure of the process line. 4. Fluid density should be the fluid density of the process fluid. 5. No wind/wave or earthquake is to be applied on the core. 6. All core bends are of large diameter (R = 1.5D). For slurry lines where the radiu...
Modeling the Jacket Pipe:
The following steps are used to model the jacket pipe: 1. An easy way is to model the jacket pipe by running through the entire core and then duplicate the core piping using a proper node increment (like 1000). 2. Change the diameter of the jacket pipe according to the specifications. 3. Change the wall thickness of the jacket pipe. 4. All jacketed bends are of short radius i.e. R=1D. For slurry lines, the radius may change. Refer to project standard. 5. In the case of Cross-Arrangement for p...
Combining the Core and Jacket Modeling:
1. The jacket will end with flange joints/ Plate/ Capped End. So at these points, there will be a physical connection between the core and the jacket. So these points need to be connected by an anchor. For example, if there is a flange at node 50 then;
Jacketed piping is a type of piping used in applications where the process fluid needs to be maintained at a specific temperature. The jacket is typically an outer shell that surrounds the inner piping, which is used to circulate a heating or cooling medium. Here are some general specifications for jacketed piping: 1. Materials:The materials used f...
The fabrication procedure for jacketed piping typically involves the following steps: 1. Material Selection:Select the appropriate materials for the inner and outer piping and the jacket. The materials should be compatible with the process fluid and the heating/cooling medium. The selection should consider factors such as temperature, pressure, cor...
The boiler is responsible for generating steam by heating water. The steam produced is then transferred to the piping system. Steam Piping Network: The piping network consists of a series of interconnected pipes that transport steam from the boiler to various points of use.
Pipe material. Pipes for steam systems are commonly manufactured from carbon steel ASTM A106. The same material may be used for condensate lines, although copper tubing is preferred in some industries.
Properly sized steam pipes ensure that steam is transported efficiently, reducing energy loss and increasing system efficiency. Discover the factors that affect steam pipe sizing, such as pressure, temperature, and flow rate, and learn how to calculate the optimal pipe size for your system.
