Why do we need piping support?
Piping must be supported in such a way as to prevent its weight from being carried by the equipment to which it is attached. The supports used must prevent excessive sagging of the pipe and at the same time must allow free movement of the pipe due to expansion or contraction. The supporting arrangement must be designed to carry the weight of the pipe, valves, fittings and insulation plus the weight of the fluid contained within the pipe. Various types of piping support are shown in Fig. 4.
Why is the weight of piping system reduced?
The weight of the piping system is reduced due to the elimination of connecting flanges or fittings.
Why are welded joints used?
Welded joints give more flexibility to the piping design as the pipes may be joined at practically any angle to each other.
Why do we need insulation in piping?
Examples would include the main steam piping and feedwater piping. In order to reduce the amount of heat lost to the surrounding air from the hot substance, the piping is covered with insulation. The insulation not only retains the heat in the hot lines but also prevents the temperature inside the process plant building from becoming uncomfortably high. In addition, insulation of hot pipe lines will prevent injury to personnel due to contact with the bare surfaces of the pipe.
How is piping designed?
The initial design of a piping system is established by the functional requirements of piping a fluid from one point to another. The detailed design is decided by criteria such as type of fluid being transported, allowable pressure drop or energy loss, desired velocity, space limitations, process requirements like free drain or requirement of straight run, stress analysis, temperature of fluid, etc. The supporting of piping systems requires a significant engineering, design, fabrication and erection effort. In some cases, special structures (like structural T or inverted L, cantilevers, U portals, pedestals, etc) must be built solely for the purpose of supporting piping systems.
What is the inside diameter of a commercial pipe?
Commercial pipe is made in standard sizes each having several different wall thicknesses or weights. Up to and including 304.8 mm (12 inch) pipe, the size is expressed as nominal (approximate) inside diameter. Above 304.8 mm, the size is given as the actual outside diameter. All classes of pipe of a given size have the same outside diameter, with the extra thickness#N#for different weights on the inside. For example, if a pipe was designated as 152.4 mm size this would mean that it has a nominal or approximate inside diameter of 152.4 mm. The outside diameter is 168.28 mm. This is a constant value no matter what the wall thickness is. The actual inside diameter of the pipe will depend upon its wall thickness. For a standard wall#N#thickness, the actual inside diameter of 152.4 mm pipe is 154.06 mm. For an extra strong wall thickness, the actual inside diameter is 146.34 mm.
What is a pipe?
A pipe can be defined as a tube made of metal, plastic, wood, concrete or fiberglass. Pipes are used to carry liquids, gases, slurries, or fine particles. A piping system is generally considered to include the complete interconnection of pipes, including in-line components such as pipe fittings and flanges. Pumps, heat exchanges, valves and tanks are also considered part of piping system. Piping systems are the arteries of our industrial processes and the contribution of piping systems are essential in an industrialized society.
What are water lines made of?
Many of our piping materials are made from plastic now. Water lines are mostly CPVC pipes and PEX pipes. Although there are several other types, those are the most common. We usually use PVC for the drainpipes in our area. It hasn’t always been this way, though. Years ago, copper was more common. Before that it was galvanized pipes and cast iron drainpipes, and even before that it was clay and concrete drainpipes. The products and materials have evolved to become much better (for the most part). However, not every innovation is sound, and sometimes a product is created or manufactured that doesn’t ultimately stand the test of time.
What happens if you get a pinhole in a copper pipe?
The water lines are always under pressure, so if there’s a pinhole in a copper pipe, more than likely there will be more leaks to follow. I would say that if you get one leak, you might want to seriously consider replacing the piping entirely.
Do plastic pipes corrode?
PEX and PVC have held up over the years, and one good thing about using plastic pipes is the fact that they don’t corrode like metal pipes do.
Is plastic drain line good?
which is unclean and unsafe. Plastic is a very good option for drain lines as long as they’re installed properly and you’re using good quality plastic products.
Can acidic water eat plastic pipes?
Acidic water will not eat away at plastic pipes. All the products that we use (and from a broader perspective, most of the products on the market today) are safe for drinking water. In other words, you don’t have to worry about the plastic degrading to the point that you’ll end up drinking it along with your water.
Does acidic water eat metal?
Not all water is non-corrosive; water quality called acidic water can actually eat away at metals. If you have copper, brass, or other kinds of metal pipes, the water will eventually eat them away until there are pinholes in the pipe. Plastic doesn’t have this kind of problem. Acidic water will not eat away at plastic pipes.
