This book includes in addition to much basic data on piping components many of the papers written by A. Markl that provide the background and theory of the B31 Pressure Piping rules. Try Gwen. Creamer sypris. Mitre Bends - A. Markl and H. Markl, Piping Flexibility Analysis - A. Rodabaugh and H. Murphy, C.

Soderberg, H. Blumberg, and D. Markl, E.

This is an old book and some of the data is dated but any piping engineer will benefit from reading it cover to cover. The other book that has suddenly become available again veteran piping engineers will appreciate this is the olde NAVCO Datalog. This little spiral bound gem includes all sorts of valuable piping data.

Probably the most data in a small package. It is important to know where you can go to ask good questions. The sources of information cited above will serve you well for about 70 percent of the piping systems that you are called upon to design. You will learn techniques for the analysis of buried systems, double containment piping systems, non-metallic piping systems plastic, glass, etc.

But the good news is that the community of piping engineers is rich in advice and in most cases quite approachable. We shall rewind and check how it is really done in practice. First the flow scheme is planned, 1 What, 2 From what point, 3 To which point Pipe sizes are selected, pipe material and pipe wall thickness are selected. We call this as piping modeling or physical design. While development of piping layout we have to consider the following Piping from source to destination should be as short as possible with minimum change in direction.

Should not hinder any normal passage way. Also should not encroach any equipment maintenance space. While carrying out pipe routing we also need to consider the following Valves, strainers, instruments on the pipe should be easily accessible. Specific requirements for instrument installation to be checked, like temperature gauge can not be installed in pipe which is less than 4 inch in size.

Example of Straight length requirement for Flow Orifice Also arrangement is kept in the pipeline so that liquid can be drained out if required.

Piping Engineering

To achieve this a DRAIN connection with Valve is provided at the lowest point of the pipeline Pipes are also slopped towards low points. For Pipeline which shall carry liquid, we have to make sure that all air is allowed to vent out of the line when the line is filled with liquid.

Let us look into typical Vent and Drain arrangement in a pipeline There are two primary reasons for insulating the pipe carrying hot fluid. Insulation preserves the heat of the fluid.

It is called Cold Insulation. It is called Anti-Sweat Insulation. In such cases pipes are insulated to reduce noise. It is called Acoustic Insulation. In that case pipe along with heat tracing element are insulated to conserve the heat of the tracer. It is called Heat Tracing Insulation. Note stagnant air is a bad conductor. So the outer surface of insulation are protected with Aluminum sheet or GI sheet cladding. Have a look at how pipes are insulated, and general components of insulation Pipe Sizing Calculation - to select required pipe diameter based on velocity and pressure drop.

Drop for that Pipe size Check Press. Drop meets Press.

Basic of Piping

Material is selected per past experience with cost in mind and per material listed in design code. If material is not listed in code we may select next suitable material listed. Find out Fluid Temp. Select Mat. In Power plant there are some piping which carries steam at high pressure and temperature.

And also there are piping which carries water at High pressure. These pipes carries the main cycle steam and water of the steam power plant. Very special care are taken for design of these piping.

First the pipe material selection for such piping is very important as it has to withstand the high pressure and may be also high temperature. As these pipes carry the main system fluid of the power plant, they are given the right of way, and routed at beginning of the overall plant layout.

Steam pipes run at very high temperature and the hot pipes expand. We have to built in flexibility in the high temperature pipe routing so that the expansion force is absorbed within the piping. Also there should be enough flexibility in these pipe routing so that high loads are not transferred to the nozzles of Turbine or Pumps There are many recognized international codes which lay down guide lines and mandatory requirements for design of such piping.

Pipe Stress Analysis We have already seen that some of the pipes are subjected to high pressure and high temperature. Also pipes carry the load of the flowing fluid. We need to check and confirm the pipe is not going to fail with these loading.

In the process of Analysis we apply various postulated loading on the pipe and find out the stress resulted from these loading. Then we check with governing codes if those stresses generated are acceptable or not. We also check out the terminal point loading generated from pipe to the equipment connected to the pipe.

This loading are to be within acceptable limits of the equipment suggested by the vendors. We also find out the pipe growth due to change in temperature and need to keep the movement of pipe within acceptable limits. Pipe Stress Analysis is an Interactive and Iterative process.

What is The Difference Between Piping and Pipeline. Piping Vs Pipeline -

Each step is checked If a check fails we have to go back, modify the layout and restart the analysis. Movement of pipe at support locations Pipe terminal point loading. Types of Pipe Supports In the beginning of this discussion we talked about various types of pipe supports.

Here is some elaboration There are three general types Rigid type no flexibility in the direction of restrain Spring type Allows pipe movement in direction of loading Dynamic Support Degree of restrain depends on acceleration of load There are two types of spring support Variable load type, here support load changes as the pipe moves. Constant load support, the load remains constant within some range of movement.

Minimum pipe size to be routed under ground shall be not less than1 inch. Pipe to be laid below Frost Zone at areas where ambient temperature goes below freezing.

Pipe may be properly wrapped and coated to prevent corrosion. Freeze Protection of outdoor Piping: In the areas where the ambient temperature goes below freezing there is a possibility that the liquid content of pipe may freeze while the plant is under shut down. For similar case pipes are wrapped with heat tracing elements to maintain the content temperature above freezing around 4 deg.

C even when the ambient temp. Electric Heat tracing is done by wrapping electric coil around pipe, which turns on as the ambient temperature goes down.

Pipes are insulated over the heat tracing coils. Heat tracing can also be done by winding Steam tubes around main pipes. We have come to the End of Session.
