1949 – Initial use of PVC pipe in North America. 1952 – PVC pipe introduced in the U.S. 1960 – Original publication of ASTM D1785 – Standard Specification for PVC Plastic Pipe, Schedules 40, 80, and 120.
Why was copper piping introduced after World War 2?
The use of lead for potable water declined sharply after World War II because of increased awareness of the dangers of lead poisoning. At this time, copper piping was introduced as a better and safer alternative to lead pipes. The major categories of plumbing systems or subsystems are:
What’s the history of pipes across the ages?
Modern History of Pipes. Wooden piping has still been found in use even as recent as the 1890’s. With the import of cast iron from the U.S in the 1960’s and light-gauge copper tubing coming on the market in the 1930’s the ability to fit piping to new and old properties became accessible to most.
When did they start using light gauge copper pipe?
During the early 1900s, heavy-walled copper joined with threaded fittings was in use, but limited to public buildings because of its high cost. However, during the 1930s light-gauge Copper tube and fittings were developed which made copper economically feasible and increased its popularity.
What can copper tubing be used for in a HVAC system?
Copper tubing is most often used for the supply of hot and cold tap water, and as a refrigerant line in HVAC systems.
What was the standard size of copper pipe?
The outside diameter was standardized as well, so all piping could be joined together without a lot of extra fuss. In other words, 1/2″ pipe had a 1/2″ inner diameter and a standard wall thickness – in the case of copper pipe, it was 1/16″. Great! So what happened? In short, progress happened.

Which is the most durable type of copper pipe?
Of all copper pipe types, Type K has the thickest walls and is the most durable. Pipe wall thickness varies according to the pipe diameter. ½-inch Type K pipe has a wall thickness of .049 inches, while ¾-inch has a thickness of .065 inches.
Are there different types of copper water pipes?
Copper pipes have been used as water supply lines in homes for decades, and you’ve probably seen them under your cabinets or overhead in your basement. Most people know that pipes come in different diameters, but what you may not realize is that some types of copper pipes are thicker than others, too.
