Metal and Plastic Use in Piping Systems

The metal is the preferred material for the components of piping systems have been used for centuries. Traditional metals used are copper and brass. Although lead is also widely used until 1950, when toxic effects were detected, resulting from the use of mercury is prohibited. Seen in recent years, many developments in the field of plumbing and piping, including the introduction of plastic pipe fittings. Although its use has been shunned by many in the first place, it extends more and more beneficial for a number of reasons. However, there are many reasons why steel reinforcement must not be replaced completely.
The introduction of plastic fittings to reduce the amount of metal used in plastic piping systems are designed as a series of advantages. Plastic Valve will never jam or stick from rust and corrosion - for what are considered maintenance. Plastic corrosion-resistant and positive impact on productivity - the plastic tube is soft and will remain from year to year, resulting in lower pressure drop over time. Plastic and much cheaper, both in hardware and installation, for example, should not be treated previously with epoxy plastic accessories.
But despite the many advantages of using the latest plastic accessories, there are several reasons why the more traditional metal connections. Despite the progress in this area, not plastic accessories of capacity management of heat and pressure to compete with the metal. In addition, the copper tubes have a lifespan of 75 years and is the best material for water systems that are difficult to replace, and use force to do it regularly. Because the metal has been used very effectively for centuries in piping systems, which is familiar and is the natural choice for the first time in my mind.
In general, the plastic box, like a great alternative to the needs of various pipes. They are inexpensive and require minimal maintenance, have excellent resistance to corrosion and easy to install. However, there are still a number of reasons, the metals are still used in many cases, such as water, where long-term is not necessary. In addition, the metal is the only answer to problems with the temperatures and pressures, and plastic fittings can deal with them.
