Let's popularize the relevant knowledge and find out:
Established in 1948, Ruihao is one of the world's leading suppliers of polymer products, with 45 factories covering 54 countries and regions, providing products and services in the fields of industry and construction.
Ruihao's residential products cover heating, refrigeration, water supply and drainage, electricity and other fields, and pipeline products occupy nearly half of the European and American markets. The history of PEX pipe production can be traced back to 1972. It is the first company in Europe to apply PEX pipes to floor heating system, and it is also a global leader in the heating industry. Both Beijing Capital International Airport and Shanghai Tomson Yipin have adopted Ruihao residential heating scheme.
Although both Ruihao and Oberno are experts in plastic pipes, compared with Oberno, Ruihao not only produces parts related to heating, but also involves the production of plastic parts such as door and window materials and rolling doors. It is the largest PVC profile sales enterprise in Germany, and Ruihao is also a supplier of parts for Volkswagen. It produced armbands and side plates for the Volkswagen Beetle 60 years ago.
Like Obono, Ruihao's factory in China is also located in Taicang, Jiangsu, but Ruihao entered China earlier, and the factory was put into use in 2004. In terms of sales, it is directly managed by China Branch. Compared with the agency model, localized operation solves the problems beyond our power, and can control suppliers in real time and customize more reasonable sales targets. At the same time, it also reflects Ruihao's emphasis on the China market.
Ruihao has a floor heating pipe and a distribution main pipe. The floor heating pipe is made of PE-Xa (cross-linked polyethylene), which is the same as Obono. After cross-linking preparation, the physical and mechanical properties of polyethylene were significantly enhanced. Compared with ordinary polyethylene, crosslinked polyethylene improves a series of physical and chemical properties of polyethylene, such as thermal strength, aging resistance, dimensional stability, stress cracking resistance and so on. It has strong durability and is a popular material for floor heating pipes.
Ruihao floor heating pipe adopts three-layer oxygen isolation structure, and the material used is slightly weaker than that of Opono's five-layer oxygen isolation pipe. However, in terms of oxygen barrier performance, the difference between three layers and five layers is not obvious, and they are all enough to be used as floor heating pipes to prevent oxygen infiltration. Because of the low material cost, the price of the three-layer oxygen barrier tube is cheaper than that of Obono, per meter 10.5 yuan.
Ruihao distribution manifold is made of brass and welded integrally. The price of the 5-ring model is 2000 yuan. Many merchants promote that brass distribution manifold products are more corrosive and less durable than stainless steel products. In fact, the corrosion of distribution manifold depends more on oxygen in water. If oxygen barrier material is used in the pipeline, the brass distribution manifold also has strong durability; On the other hand, if the oxygen blocking pipe is not used, the oxygen in the water will not only corrode metals, but also easily cause microbial growth, and any distribution manifold may be blocked. Therefore, it is suggested that users should pay more attention to the oxygen barrier performance of pipelines instead of distributing manifold materials, and both brass and stainless steel can be used.
It should be noted that there is also a Ruihao company that produces floor heating related products in China and Shanghai, but it has nothing to do with German Ruihao, but a brand named "Shanghai Ruihao" established in 2007. German Ruihao's trademark is "REHAU", while Shanghai Ruihao's trademark is "RHPIPE", so consumers need to distinguish it when buying.
