Why Should We Check the Piping Checklist Before Buying

In our houses or in the big companies for plumbing the coupling pipe requires and to joint two pipes, or to increase the length of the pipe, you have to take the help of a coupling pipe. This type of pipes comes in a short form. Even to prevent the leakage of a plumbing area one has to fit the pipe there. Today the use of the coupling pipe becomes an essential part of our daily life especially those who work in the plumbing.

They know very well where to use it and how to fit the coupling pipe, in the correct position. Those who regularly deal with this plumbing work always check the piping checklist before fitting it in a position. They examine the density of the pipe and the thickness of the pipe also. The steel and copper pipes run long, thus most of the in plumbing people prefer to use two pipes.

There one can find two types of coupling pipe in the market and in various forms. The plumber’s offer gives suggestions to their customers to buy the best coupling pipe so that it offers a long-term service.

Few Things To Consider For Isometric Piping Checklist

For isometric piping checklist, one must see the rightness of these points.

  • Valve tag nos
  • Support location
  • Bill of material
  • Insulation
  • North direction
  • Instrument connection
  • Flow arrow
  • Coordinates and elevations
  • Equipment nos
  • High end vent, small point drain
  • Equipment nozzle connection
  • Nozzle nos
  • Hydro test expel and drain
  • Start point location
  • Branch connection
  • row numbers (nos.)       
  • Endpoint location
  • Line specs

In addition, many more like these things. If you do not consider these things then you may face many complications.

Some Documents That You Need To See Before Piping

There are some documents, which one should observe before the isometric piping checklist. Let us see few of the credentials that are important.

  • pressure analysis report
  • Piping and tool figure
  • particular items sketches
  • Piping layouts
  • Pipe bear standard
  • Sectional drawings
  • Piping specification
  • Equipment drawings
  • Nozzle orientations

Few Points To Remember For Piping Isometrics Checking

Another most important thing is to make sure some points of this piping checklist or isometrics examination. Here is a small amount of of them.

1. The thrust suction should always be immense, than the expulsion row.

2. Use eccentric reducers to stay away since the air obstruct in the pipe.

3. Maintain downward position for both the compressor line up and pump suction row.

4. Should have rising position to the PSV outlet.

5. The valve in service elevation should be minimum; from 250 mm to 1200 mm from the floor.

6. Trickle leg compulsory for haze column heading

7. Nozzle directions should remain as per the piping necessity.

8. Provide hold up to the organize station equally sides of the manage regulators

9. Make employ of weld collar projection for force piping

10. The rot meters established in the upright lope with the jog in a growing route

11. The inch data should mentioned at the base section of isometric pipe.

12. The printing writing should be clear so that everyone can read it.

13. All sob gaps for atm expel line and its necessity should be indicated.

14. Flanged reels are there so that in case you cannot able to remove the conical strainer.

 15. All the common requirements one will have to check like steadiness, in a row items, barriers, sustain clearness and visual supplies.

Importance Of Coupling Pipe

When it comes to the importance of coupling pipe or piping checklist, then the first thing, which will come to our mind, without this pipes you will not join the pipes one with another, even you cannot solve the leakage problem of a pipe. On the other hand, if you do not see checklist of piping before buying it then you may face many complication, which will unable to provide a long service for the plumbing.


Therefore here I try to give some valuable information related to the piping checklist and coupling pipe. Before purchasing any pipes, one has to remember all the points that I mentioned here.


Everything You Need To Know About Coupling Pipe Fitting

The coupling pipe is used for plumbing and to join the edges to increase the length of the pipe. These pipes are too short in length normally. Most in the big factories or even sometimes in the houses this type of coupling found. Today the use of these pipes becomes very essential to set pipes altogether. Even to build sturdy association between to joints these pipes are used. At the same time to change the pipe size, these coupling are used.

Even sometime, to check the thickness, pipe thickness calculation is used. To repair a broken pipe or to solve the leaking problem this coupling pipe plays a central function. These pipes are made of different things like copper and steel. Mostly the steel and copper coupling pipes people buy because there will be seen no rust in the coupling pipe.

Different Categories Of Couplings Pipe

There are too many people, who do not know about much of the coupling pipe or pipe thickness calculation. Thus, now I will discuss with all of you about the categories of this coupling pipe in detail. Let us have a quick look on this matter.

There are mainly two types of coupling pipe in the market.

1. Permanent coupling

2. Removable coupling

Now the question that may come to your mind, what is permanent and removable coupling, therefore here it is in detail for you.

1. Permanent Coupling:

This type of coupling pipe; used for soldering in the, strengthen or copper pipes. If it fits well then it can provide a long-term service to the joint of two pipes without contravention or damaging. The permanent coupling proposes brilliant firmness also.

2. Removable Coupling:

The removable coupling always comes in filament design, which lets the pipes tighten to tight that it never separate. This type of pipes is quite superior to any other coupling pipes. The finish part of these pipes is threaded. Even it helps in pipe thickness calculation to give you the right result.

Few Types Of Couplings Pipe

There are also some other types of coupling pipes we will see. Now I will give a complete detail about these types. Let us have a quick look on this matter.

1. Reducing Coupling:

This type of pipe commonly used for unlike types of diameters. On both the site there are two dissimilar extent of thread you will find. Even it is used for joining the fat pipe with small pipes or tiny pipes installation. The designs also different and not have features in thread. It maintains a easy and stepped down; outline.

2. Full Coupling:

To unite the small-bore pipes people used this pipe. You will socket ends in this occupied coupling pipe. To connect the pipe with pipe or pipe with nipple, people take the help of this full coupling. On the other hand, in pipe thickness calculation many of us utilize it.

3. Half Coupling:

Mainly for using small bore, branching to a vassal or big bore pipe. This type of pipe can be fibered or whole. Only in one side, you will see the opening end or cotton end. Thus, a half coupling can also connect with a huge bore pipe directly. This type of pipe can seen many places also.

4. Slip Coupling / Repair Coupling:

This type of pipe has two pipes and together of the pipes is diverse in length. This slip coupling made of with no any interior discontinue, which permits it fit in the right position very tightly. However, for the repair coupling there remains a little seep out because of the corrosion that may be incise for the moment any time with any reason. It is always important to see the installation location whether it fits in the correct area or not. Without it, the pipes will not work perfectly. You can face many complications also.

5. Compression Coupling:

A compression-coupling pipe joints two united pipes absolutely. The tapered sleeve will remain over one junction and other two flanges strained over mechanically. The pipes supply enough makes contact with force also.


Therefore, here I try to give a complete detail about the coupling pipe and about the different types of it. Those who still do not know about the coupling pipe should definitely know about it.
