There are many kinds of pipes,PP-R pipe, PVC-U pipes, plastic-lined steel, stainless steel pipe, brass pipe.Pipes should be stable and reliable, watertight, not burst. What we said the security durability is not occur the pipe leakage, burst endanger the safety of life during the service life.
Compare with others,in the case of large temperature difference deformation are prone to cause leakage, and the compressive capacity is small, easy to brittle fracture, these are doomed to its not applicable to heating for a long time, should not be used in the cold north, not suitable for high-rise buildings.
Composite pipe collect both plastic pipe and metal pipe’s advantages. Because the plastic and metal expansion coefficient is different, After using for a long time it will lead to pipe layer, cause harm.
Copper pipes can be durable, long-term safety and reliability and longevity of the same building. In addition, brass pipe is durable, low thermal expansion coefficient,is particularly suitable for embedding in concrete walls without worrying about the walls cracking. However, the price of copper is more expensive.
Brass can inhibit the growth of bacteria
The main ingredient for a number of plastic pipe polymer, which has some toxicity, relatively easy to penetrate, particularly if used in drinking water supply systems, which has serious harm to humans.Copper pipe inhibit the growth of bacteria,E. coli can no longer continue to multiply in the copper piping, keeping drinking water clean.
Pp-r and copper tube can be embedded inside the wall
PP-R pipes and brass pipes and fittings varieties and specifications are complete,you can choose from 6mm-250mm arbitrary. PP-R pipe can be seamlessly welded. It has the advantage of relatively cheap and easy construction. The copper tube cutting, bending, welding process is also simple to connect a variety of forms, brazing, card sets, crimp, plug, flange, trenches, etc., can meet a variety of different occasions, the situation needs.
Currently on the market there are the following three pipes , including:
Hot and cold water with three polypropylene (PPR) pipe with health non-toxic, heat resistance, corrosion resistance, good insulation, installation is simple and reliable and can be used directly on pure water, water piping systems.
Plastic coated brass pipe with a high temperature, corrosion resistance, high strength, anti-permeability and good.
Building drainage with a hard PVC (PVC-U) pipes compared with traditional cast iron pipes, light weight, small inner wall of the fluid resistance, corrosion resistance and good.
No matter that kind of pipes,please pay attention:
Tubing express on the execution of the standard for the corresponding national standards, the implementation of the national standard of choose and buy as far as possible.
Pipe appearance should be smooth, flat, no blisters, colour and lustre is uniform, without impurities, even wall thickness.
The same material and wall thickness of the thicker steel tubes of choose and buy.
Use pipes to note:
Buried pipes concealed as far as possible a complete tube, less joints, pipes do not go as far as possible from the ground.
After the pipe installation is complete, must first test,then be closed.
After installation must obtain warranty book, the pipeline route map.
Please plumbing manufacturers recommend installing plumbing or professional team.
