Depends on what pipe you are asking about. Most pipe such as PVC has a max heat rating for internal and external temperatures. this is why regular white PVC should never be used for hot water from a hot water heater which can be 120 degrees (F) or more and melt regular PVC. That is why they recommend using CPVC which has a higher temperature rating. Depends on what pipe you are asking about.

Advantage of shell and tube heat exchanger over double pipe heat exchanger?
**** you.......... pls somebody answer Double pipe heat exchanger consists of two concentric pipes of different diameters.One pipe is for hot fluid and another is for cold fluid.Both may have same flow direction(COCURRENT) and opposite direction(COUNTERCURRENT). Shell and tube heat exchanger consists of a shell in which large number of parallel tubes are present.One fluid hot or cold flow in shell and other hot or cold flow in the tubes. Also in case of shell & tube(S&T) the hot fluid will have more turbulence than in double pipe heat exchanger (HE) since there are no of tubes within a shell the area for convective heat transfer is considerably increased. so these are much more preferredTherefore the rate of heat transfer is greater in shell and tube because large surface area and enough contacting time
What is the difference between a compression fitting and a capillary fitting?
The difference between a compression fitting, and a capillary fitting is: in plumbing, are two types of fastening pipe together. Compression is the squeezing of a material around that of another material to secure a leak proof joint. A capillary fitting is a fitting usually involving a heat source as in copper pipe being soldered together. Soldering two pieces of pipe using a gas propane torch and a joiner which is simply another small piece of copper pipe that is made larger at both end to allow the pipes to enter each end of the joiner. After cleaning the ends and applying a flux to the ends you are ready to fasten the pipes together by just heating the joiner when the temperature is hot enough the solder will melt around the pipe. In a vertical position the top will solder easily, with gravity and heat. The bottom will use capillary action which is a sucking up of the solder due to the heat and flux.
What is b class ms pipe?
B Class pipe Ms- This pipe is made out of Mild Steel, wall thickness will be 3.2 mm +/- 10%, this pipe will be painted in Blue colour at the end. B Class will be medium duty pipe.
What is 40 mm NB pipe?
the inner diameter of the pipe Nominal bore (NB) is 40 mm
How do you determine invert from one manhole to another?
Given one invert, and the length of the pipe and the slope of the pipe, you multiply the the length of the pipe by it's slope (expressed as a decimal ratio) and add the result to the known invert.
What is the difference between closed heat pipe and open heat pipe?
Pressure rises in the tube.
What is the purpose of air vent in infrastructure pipe work?
The purpose of air vent on pipe works of infrastrucure
What is heat number of pipes?
It is a number that allows the pipe to be traced all the way back to the metal it was made from, important for quality control.
Disadvantages of heat pipe?
Heat pipe collectors must be mounted with a minimum tilt angle of around 25° in order for the internal fluid of the heat pipe to return to the hot absorber.
What is the different between tubes and pipes?
Pipe n tube are same in shape etc. BUT only difference is Pipe is used for Transferring Material (Gas, Liquid etc.) AND where it is used for Heat Exchanging purpose , It is called TUBE.

What's the primary function of a pipe clamp?
The purpose if a pipe clamp is to hold it in place. Pipe clamps are typically fastened onto something that is stationary to fulfill its purpose. An example would be a wall for pipe associated with guttering.
What insulators could keep heat in a pipe?
Try wrapping the pipe in tin foil as this keeps the heat in. If not, try cutting styrofoam into the shape of the pipe and attaching it to it, keeping it together with electrical tape.
What is a heat no on pipe?
Used for inspection. Heat numbers make it possible to trace pipe from spools fabricated on a job to material documentation from a given melt. The matching documents will tell when and where the pipe was made, the material used and the pipe grade etc.
What is the purpose of pipe coupling?
To joint two or more sections of pipe into a single continuous conduit.
What was the purpose of hydrostatic test?
for ex; design pressure in pipe 100bar,and what is test pressure in pipe
