Britain uses copper pipe as water supply pipe, has a history of hundreds of years. In China, the old streets of Shanghai and Beijing Union Hospital in the last century 20-30 years installed copper water pipes have been safely used for more than 80 years, so far the performance is still good; Shanghai International Hotel, Ruijin Hotel and other pre-liberation installation of copper pipes, is still in normal use. Copper pipe long life, corrosion resistance, high reliability has been tested for practice. Today we share with you the history of copper pipe in the United States in the history of the use of change.
1965: For many years prior to 1965, copper piping was arguably the backbone of water piping in the United States, accounting for a whopping 79% of all water piping, far outpacing galvanized steel pipe at 13% and plastic piping at 2%.
1965-2000: In the following 30 years, the situation has changed, plastic pipe with low price quickly seize the market, share continued to grow, in 2000 reached a peak of 52%, the impact of copper piping market share has declined. And galvanized pipe is extremely easy to corrosion and rust, pollution of water quality shortcomings gradually eliminated by the market.
2000-2009: In 2000, the market trend was once again reversed. More and more areas in the United States began to reuse copper piping, in 2009 a new round of surveys, the proportion of copper piping has returned to 78% and is still maintaining an upward trend, while the plastic piping is declining, the market share fell to 22%.
Why has copper returned as the dominant water pipe material of choice in the U.S. after a brief downturn? And why has plastic piping declined so rapidly and lost its marketability in just nine years?
The plastic piping boom that began in the 1980s was due more to its price advantage, however, after a period of time, plastic piping appeared to be leaking, cracking and a variety of other quality problems, people are back to choose more time-tested copper piping.
According to the official website of the American Copper Development Association, around 2150 B.C., the ancient Egyptians used copper as a piping material for distributing water. The ancient Romans used copper in water pipes and cisterns. By the 1940s, copper had become a common plumbing material in developed countries. In fact, copper has been used for thousands of years to deliver safe drinking water because of its impermeable, durable, safe and recyclable properties.
Impermeable
Compared to plastic or other plumbing materials, copper is completely impermeable, especially copper piping systems with 99.9% copper content, which virtually eliminates the possibility of contaminants penetrating the pipe walls and affecting water quality.
Durability
Copper is highly resistant to corrosion in most environments and has excellent strength. It can withstand considerable changes in stress and is virtually unbreakable in harsh climates, whether it be high temperatures or freezing cold. In addition, even when exposed to sunlight and oxidizers, there is no risk of leakage in copper pipes, whereas plastic pipes are clearly at risk in these extreme usage environments.
" Environmentally healthy
Copper's long history and wide range of applications have enabled researchers to study its properties, composition, and the substances that may be precipitated when it is used in water transfer piping, the health effects of these substances, and how to control the precipitates, thus ensuring that copper piping is safe and reliable for use in the real world.
