Pipe Joining for Plumbing and Heating Systems

Controlling and protecting your water www.caleffi.com - Milwaukee, WI USA FROM THE GENERAL MANAGER & CEO Dear Plumbing and Hydronic Professional, It was the 1990s when I attempted my first soldering job. What a mess! Although the replacement water softener ended up working fine, my workmanship was nothing short of “bush league”. There was more solder on the basement floor and on the outside of the pipe, than there was in the completed joint. Fortunately the softener was in my own home. I’ve long since moved on from there but would not be surprised if someday that work is posted up on one of those “hacked-up install” websites! That experience gave me an appreciation for the skill that goes into producing a reliable pipe connection in a timely manner. Fast forwarding to today there are several new pipe joining technologies available that not only produce a reliable connection, but require significantly less time than traditional methods. As skilled labor becomes increasingly scarce, it’s likely that manufacturers will introduce even more innovate “quick-joining” technologies and methods. This issue of idronics discusses classic and contemporary methods of joining piping in hydronic and plumbing applications. -
History of Threaded Pipe Connections
Jacques Jumeau English version History of technologies linked to heating. Chapter 1 History of threaded pipe connections Copyright: Jacques Jumeau 1st edition 2010/04/23 Copy is allowed, provided you cite the origin: Ultimheat Museum 1 Update 2019/02/21 History of threaded pipe connections At the beginning of the 19th century, the development of pumps and steam engines posed the problem of a simple, solid, waterproof and pressure-resistant connection of metal pipes. Each manufacturer designed their own system and very soon appeared problems of compatibility and maintenance. In 1841 the English engineer and industrialist, Joseph Whitworth, of Manchester, presented to the Institute of Civil Engineers, a memoir to demonstrate the advantage of applying, for railways, navigation and manufactures, a uniform system screw threads, all over England. He gave a table summarizing the main dimensions which were quickly adopted by several companies and builders. Joseph Whitworth focused on determining the pitch, depth, and shape of screw threads to match their diameter. He endeavored to establish such proportions that, while retaining the necessary power of the nets, they present, at the same time, a great solidity, and may serve both for iron and cast iron. It was based on a 55-degree thread angle with rounded roots and crests of threads to save manufacturing tools. This form of threading, was later declined into a cylindrical female part and a conical male part with a taper angle of 1/16 (6.25%) and was then chosen as the most efficient, because it allowed to perform a Pipe sealing on a step. -

Definition of Pipe Thread Acronyms National Pipe Thread Taper (NPT) Is a U.S
Pipe Thread Definitions Checking thread type can be done with a thread gauge. Thread types can also be specified on existing pipe labels, manufacturer specifications or on manufacturer drawings. The specified sealant tape or paste should be used when required for installation. Definition of Pipe Thread Acronyms National Pipe Thread Taper (NPT) is a U.S. standard for tapered NPT National Pipe Thread (tapered) threads on threaded pipes and fittings. In contrast to straight threads, a taper thread will be tighter and have a fluid/air-tight seal . FPT is a term for pipe fittings that MIP (male iron pipe) or MNPT (male Female Pipe Thread FPT national pipe thread) fittings fit into. Female threads are internal located (interchangeable with NPT) inside of the pipe or fitting. Female Iron Pipe (interchangeable FIP, Female Iron Pipe, or Female International Pipe- Similar to FPT, FIP FIP with NPT) connect NPT pipe together with internal threads.
