Your Plumber in Trinity, and Nominal Pipe Size

Any experienced plumber knows that not all pipe sizes are the same. All pipes in the US follow the Nominal Pipe Size standard, as this article excerpt shows: In March 1927, the American Standards Association authorized a committee to standardize the dimensions of wrought steel and wrought iron pipe and tubing. At that time only a small selection of wall thicknesses were in use: standard weight (STD), extra-strong (XS), and double extra-strong (XXS), based on the iron pipe size (IPS) system of the day. However these three sizes did not fit all applications. The committee surveyed the industry and created a system of schedule numbers that designated wall thicknesses based on smaller steps between sizes,[3] although IPS and NPS numbers remain equivalent.

The original intent was that each schedule would relate to a given pressure rating, however the numbers deviated so far from wall thicknesses in common use that this original intent could not be accomplished.[3][note 1] Also, in 1939, it was hoped that the designations of STD, XS, and XXS would be phased out by schedule numbers, however those original terms are still in common use today (although sometimes referred to as standard, extra-heavy (XH), and double extra-heavy (XXH), respectively). Since the original schedules were created, there have been many revisions and additions to the tables of pipe sizes based on industry use and on standards from API, ASTM, and others.[3] [READ MORE]. The pipe size a Trinity plumber selects depends on the project in question.

Why Pipe Diameters Matter in Plumbing Upgrades

If you ever have to do a plumbing upgrade, or re piping in your home, if you use a bigger diameter pipe in the wrong place, you could find your water pressure dropping. Inversely, if you use a smaller diameter pipe your water pressure will be too powerful. Larger diameter pipes are usually used in places like drains, while smaller diameter pipes are used for kitchen and bathroom sinks.

When in doubt about what pipe size to use, don’t take a chance. Call in a professional and licensed plumber.
