Pipe Threadings used in process Industries

-
I have seen many has problem in understanding the pipe adopters used in process industries. I too had the problem in initial stage but as time passed I get to learn about different adopters. I want to share some information about the adopters for the people like me who is facing problem in their initial stage in process industries.
The main confusion in the choice of adopter is their pipe threading. If the pipe has different threading then we have to use compatible adopter for that. For example, if we have 1/2” NPT(M) pressure gauge which has to be mounted on ½”  NPT(M) pressure line, we are bound to use ½”NPT(F) to ½”NPT(F) adopter. This adopter can also be written as ½”X ½” NPT(F) adopter. We can’t use pipe Nipple or adopter having BSP threading, which normally people try to do. If you seriously wants to fit the ½” NPT(M) into ½” BSP(F) pipe, then you have to use the proper adopter like 1/2” NPT(F) X ½” BSP(M) otherwise it will damage the treading of gauge as well as the adopter. It can also be fatal for the pressurized system because sealing will not be proper. If you do put NPT into a BSP socket, for example, and you have a bad result (as in somebody gets injured, or property gets damaged, or both) you should not be surprised when your insurer refuses to cover the damage claims.

I will try to explain each type of threading for the beginners in my next post.


Keep watching for many interesting topics which many misses thinking the topic as not significant. But keep in mind, nothing in this world is insignificant. Everything has its importance in your life when time comes. Some get to know it early some later in their life.

What do you mean by CryoVolcano?

-
Image
A cryovolcano (colloquially known as an ice volcano ) erupts slurries of volatile compounds such as water or methane instead of lava. These substances are usually liquids and form plumes, but can also be in vapour form. After eruption, cryomagma condenses to a solid form when exposed to the very low surrounding temperature. Cryovolcanoes form on icy moons, and possibly on other low-temperature astronomical objects (e.g., Kuiper belt objects). The energy required to melt ices and produce cryovolcanoes usually comes from tidal friction. It has also been suggested that translucent deposits of frozen materials could create a sub-surface greenhouse effect that would accumulate the required heat. Ice volcanoes were first observed on Neptune's moon Triton during the Voyager 2 flyby in 1989. On November 27, 2005 Cassini photographed geysers on the south pole of Enceladus. Indirect evidence of cryovolcanic activity was later observed on several other icy moons of our Solar Sys...

How to Backup up hardware key

-

If you have a industrial software which uses hardware key to authenticate the license, then it is very difficult to run the software without the key dongle plugged in. Their is a chance that the key might be stolen as it looks just like pen drive. If the key dongle is stolen, then the software will not run and you have to buy another license key dongle if  you are not under service contract. In this article I'll describe you with the method by which you can backup your hardware dongle to enable you to run the software without the key dongle plugged in. Note: All the steps has to be done while the dongle is plugged in and the application is running. Step 1. Download Sentinel key reader Dumper.exe . This is used to dump the key file in the dongle which is otherwise impossible to read. Note: This can only be used with Sentinel SuperPro/UltraPro keys . The best way to find whether your key is Sentinel is that when you run the application dumper.exe, it will not show the mess...

What is atomic clock?

 Have you wondered how time works?  What do you mean by 1 sec?  How the duration of 1 sec is decided? All these questions will be answered when you understand the atomic clock. World time is based upon a reference and that reference is the atomic clock.  What is atomic clock An atomic clock is a clock device that uses an electronic transition frequency in the microwave, optical, or ultraviolet region of the electromagnetic spectrum of atoms as a frequency standard for its timekeeping element. i.e. locking an electronic oscillator to the frequency of an atomic transition. The transition is generally between hyperfine level which is a small shifts and splittings in the energy levels of atoms resulted from interaction between the magnetic moments associated with electron spin and the electrons' orbital angular momentum. Elements used for atomic clock 1. Cesium-133 2. Rubidium-87 Cesium atomic clock It employ a beam of cesium atoms. The clock sepa...
