What are the classifications of metal pipes?

Galvanized pipe

As a water pipe, after several years of use, a large amount of rust and scale will be produced in the pipe. The yellow water that flows out not only pollures sanitary ware, but also contains bacteria bred on the unsmooth inner wall, resulting in excessive heavy metal content in the water, which seriously endangers human health (the state has issued regulations to prohibit drinking water pipes).

Copper pipe

It has the advantages of corrosion resistance, bacteria elimination and so on. It is the best product in the water pipe. The way of copper pipe interface is sleeve, welding and self-locking circlip type connection. The sleeve for a long time there is the problem of aging water leakage, welding is the use of hot melt process, the two connector welding, to achieve the effect of connection. High connection strength, welding seam gas protection is difficult to reach the standard, resulting in easy rust of the weld, directly reduce the service life of the pipeline; The installation quality depends on the welding worker's technology strongly, and the quality is difficult to be stable. The operation is simple and convenient, construction personnel only need to be familiar with the operation requirements, a little practice can master. When connecting, the end face of the pipe incision should be perpendicular to the pipe axis, the burrs inside and outside the incision should be cleaned, and the depth to be inserted should be marked on the outside of the front end of the copper pipe with a marker, and then the copper pipe should be forcibly inserted into the pipe fitting to the end of the pipe. Low installation risk, suitable for various installation environment, reusable, environmental protection and energy saving; No leakage, shock proof, heat expansion and cold contraction, safe to use, durable and reliable.

One disadvantage of copper pipes is that they conduct heat quickly, so the hot water pipes produced by famous copper pipe manufacturers are covered with plastic and foaming agents to prevent the heat from escaping. Another disadvantage of copper pipes is that they are expensive. The construction cost of welding is higher, and few families use welded copper pipes for decoration.

Stainless Steel pipe -------- The new favorite of home plumbing

Stainless steel is safe, sanitary, healthy, durable, eliminates the problem of plastic pipe pollution, the price is also much cheaper than copper pipe, is the preferred water pipe material.

Stainless steel material is not only used in medical treatment, food, beverage, petrochemical and tableware and teapots in our homes, but also can be implanted into the human body, such as artificial steel skeleton, artificial teeth and so on. After decades of application has proved that stainless steel material has excellent corrosion resistance, health, no rust, no scaling, no dialysis release foreign matter, good self-cleaning, long service life, environmental protection, can be 100% recycled.
