By James Axler Subscribe to RSS | July 21st 2012 | Views:

Gas testing is an integral part of your home as well as commercial use of gas. You definitely will be calling in the experts to get the job done. Now as a person who employs people for such jobs, it is also essential that you know a bit about what is being done so that you are in a better position to supervise the job.

You have what are known as purge points or specific places where nitrogen can be introduced or removed. This can also be used for piping in natural gas at different stages. It is also necessary that the fuel trains or not overly exposed to high pressure. This can lead to damage of the various parts in the process of pressure testing. The professional you hire will make use of line blinds. It is possible that valves may be accidently left open or could even leak when closed. Blinds will give you the isolation and remove any chance of the devices getting damaged.

When repairs are in progress some parts of the pipe are removed in order to make way for tees or for the inclusion of blinds. In such cases, the professional will have to ensure that pipe supports are in place so that the disconnected sections of the pipe do not fall off. You have to know that flange gaskets, no matter how good a condition they may be in, are prohibited from use. To prevent any leakage you have to make use of new gaskets and well rated bolts for the flanges.

All the materials used for the pipes and the fittings have to be of good quality material. For this you can only depend on tried and tested brands. Make sure that your professional checks them out for any damages or manufacturing issues. You will have to look out for pinholes creeping up in cast iron fittings and also for threads that may not be aligned correctly. The right grade of pipe also needs to be used for the job.

You have to ensure that the purge points are well ventilated. Breathing in even a small amount of concentrated nitrogen can prove to be fatal. Keep a watch on the area where nitrogen is being purged. All the people working around need to be well versed in what to dn the case of an exposure.

Once you are sure of these basic aspects, you will be able to get the job done well.
