Coppers are essentially commercially pure copper, which ordinarily is very soft and ductile, containing up to about 0.7% total impurities.
These materials are used for their electrical and thermal conductivity, corrosion resistance, appearance and colour, and ease of working.
They have the highest conductivity of the engineering metals and are very ductile and easy to braze, and generally to weld.
Typical applications include electrical wiring and fittings, busbars, heat exchangers, roofs, wall cladding, tubes for water, air and process equipment.
* Durable: Copper is the most dependable and most used material for plumbing tube in the developed world.
Copper is beneficial in underground applications because it is highly corrosion resistant in most underground environments.
Because of its superior strength it can withstand stresses without failure.
Plastics on the other hand, are prone to crack, rupture and leak when freezing and thawing and other natural occurrences cause the ground to settle and move.
Copper can be exposed to UV rays (sunshine) and oxidizing disinfectants (chlorine, chloramines, chlorine dioxide, etc.)
Without risk of cracking or failure. Meanwhile, plastic pipe has exhibited an above average risk of premature failure fue to oxidative degradation
2 in underground potable water systems treated with an oxidizing disinfectant like chlorine.
*Sustainable: Aproperly designed and installed copper system is built to last
but when it's time to replace the line copper can be recycled into another pipe or product without any loss to its beneficial properties.
Its long life cycle, combined with its ease of recyclability back to the same metal purity (not downcycled to a lower purity or lesser use, like many plastics) makes copper a truly sustainable piping material.
In addition, no matter how long it has been buried or in service, copper maintains its value—returning 80 - 90 percent or more of its original cost when it is reclaimed and sold for recycling. Production Range of seamless size OD6~OD160mm(6 inch).
