In the last century, galvanized steel pipe was the most widely used drinking water pipeline, which was welcomed by users because of its low cost. However, after years of use, the rust scale produced in the pipe breeds bacteria, and the content of heavy metals is too high, resulting in secondary pollution of water quality. At the beginning of the new century, it is forbidden to use it in indoor water supply pipes.

PPR pipe, also born in the last century, random polypropylene, because of its good pressure resistance, impermeability, hot melt, convenient installation and long service life of 50 years, has become the most economical and practical product and has been vigorously promoted.

However, the quality of pipes in the market is mixed, and some bad products will have harmful substances such as plasticizer, lead and mercury dissolved in water after long-term use. Moreover, the lack of self-cleaning and sterilization function of water pipes will breed bacteria and cause hidden dangers to users.

In order to eliminate everyone's hidden dangers to safety issues, many conscience enterprises continue to introduce high-quality products.

The brand from Italy, established more than 40 years ago, adopts various technologies to improve product quality: the inner wall is smooth and it is not easy to attach breeding materials; Anti-ultraviolet, inhibit bacterial growth; Copper and water are separated to prevent secondary pollution. The diameter of water flow on the water pipe wall has reached the European standard.

In China, Rifeng Guan is a household name. In 1990s, Rifeng took the lead in introducing European technology and equipment, and started the road of self-research. At present, many places in China have built large-scale production bases and hundreds of production lines. Rifeng Pipe passed the long-term water pressure test of 9760 hours in the raw material stage to ensure the safety of use. The wall thickness is higher than the design requirements of GB/T 18742. The highest temperature can reach 95℃, and it is resistant to temperature and pressure.

Shanghai Poly Pipeline, which was born in the new century, pushed the pipeline quality to a new height. Poly's: yellow tube, long tube, green tube, blue tube and orange tube, suitable for different site needs.

Micro process from Germany uses non-nickel plated European standard brass in pipe joints. Brass material has stable performance, is not easy to corrode, can sterilize and inhibit bacteria, and is the top grade in water pipes. It's just that the price is worthy of the quality, which only appears in Randy's upgrade bag.

The service life of high-quality pipeline is more than 50 years. In this half century, it will silently protect the health of your whole family.
