PPR pipe : cost-effective and environmentally friendly
As a new pipe materials , PPR pipe has a unique advantage , It can be used as a cold water pipe , hot water pipes can also be used . PPR pipe interface with hot-melt technology , fully integrated between the tubes together, so once installed pressure test , there are not the same as the aluminum pipe leaking a long time on the aging phenomenon .
Advantages: affordable, stable performance , heat insulation , corrosion resistance, smooth wall without fouling, pipeline system is safe and reliable and does not penetrate , the age up to 50 years .
Cons: Construction technically demanding, requires the use of special tools and construction professionals in order to ensure system security.
Brass : corrosion resistance also bactericidal
The water in the upper product , the way the interface has a brass ferrule and welding two card sets with plastic pipe , as long there is no aging problem of water leakage . Currently , most of the brass installation using welded, welded interface is welded together by oxygen , so it can follow the same PPR pipes , never leak . Its expensive, usually in luxury apartments or villas to use more.
Advantages: high strength, stable performance, sterilization , and difficult to corrosion.
Disadvantages: high prices, difficult construction , in the cold winter , can easily cause heat loss , energy consumption , high cost.
Plastic pipe : easy to aging and easy leakage
Aluminum tubes used to be more popular on the market as a pipe, the current market more famous , HSBC and Kinder , due to its light weight, durable and easy construction , which can be more suitable for use in bending of home improvement . Relatively new concept in the decoration of Guangdong and Shanghai , aluminum pipe has gradually no market , products are being phased out .
Pros: the price is cheaper, can be arbitrary flexion , smooth surface to facilitate construction.
Disadvantages: easy to aging , the use of hidden dangers and more, life is short , proved that after one year , the pipe joints prone to leakage.
Galvanized pipe : easy to plug easily contaminated
Long time no plumbing , you suddenly open the outflow is actually found "yellow " water , previously prone galvanized iron pipes in an old house in such a thing, such a " yellow" water is also harmful to the human body . Chinese Ministry of Construction and other four ministries have issued a document explicitly disabled galvanized pipe from 2000 onwards, the new district currently has rarely used the cold water pipe galvanized pipe up .
Pros: variety, tube supporting the many.
Cons: belong to the state ban on the use of elimination products , corrosive rust, leading to poor water , can easily cause water pollution .
PVC pipe : easy to break easily deformed
Is actually a plastic tube , usually with adhesive bonding interface . Because of its ability to frost and heat is not good , it is difficult to use as a hot water pipe ; strength does not apply to water mains pressure requirements, so cold water pipes are rarely used. In most cases , PVC pipe for wire and pipes and sewage pipes . Also, make PVC softer phthalate chemical additives on the human body kidney, liver, testicles great influence to cause cancer, kidney damage , so I do not recommend that you buy .
Pros: lightweight, easy to install, low cost , and easy to corrupt .
Disadvantages: poor quality will be very brittle, easily broken , heat can easily deformed.
