Liansu is a leading enterprise in the plastic pipe industry, with the largest sales volume in China. In 2017, Liansu's revenue reached more than 20 billion yuan, of which plastic pipes accounted for 88.9%, with superior strength, far exceeding brands such as Rifeng and Weixing, and occupying an absolute advantage in the market.
 
At present, Lesso has 26 production bases in the world, the production scale is also the largest in the domestic pipeline enterprises, the production capacity is very strong, in addition to its own products, Lesso also accepts OEM business, part of the well-known Siemens socket is made by Lesso OEM, enough to confirm the manufacturing strength of Lesso and the reliability of the product.
 
In recent years, Liansu has begun to implement a strategy of diversification and overseas expansion, through the acquisition of home building materials companies to penetrate into the field of plumbing and sanitary ware, doors and windows and other building materials, and its categories have exceeded 10,000, achieving full coverage of building materials products. Although compared with the plastic pipe business, the share of home building materials and overseas markets in the total revenue is still relatively small, but the potential is huge, with an annual growth rate of more than 30%.
 
However, so far, pipes are still the most important business of Liansu, of which PVC pipes account for 75% of the total, this revenue structure has a great relationship with product demand, PPR is mainly used as a water supply pipe for building home decoration in the domestic market, and the application scenarios are not as rich as PE and PVC.
 
 There are two kinds of double-layer pipes and single-layer pipes, and its products have reached the domestic first-class level in terms of appearance, inner wall, longitudinal retraction rate and other indicators. Compared with metal pipes, PPR has obvious advantages due to better pressure-bearing capacity, strong impact resistance, lower thermal conductivity, and stronger corrosion resistance. However, PPR is not capable of all situations, although PPR can withstand high temperature up to 95°C in a short time, but if the water supply temperature is too high, the service life of the pipe will be greatly shortened, and it is recommended that the long-term use temperature is lower than 70°C.
 
Diamond series two-color PP-R water supply pipe is the main product of Liansu PPR pipe, positioning is relatively high-end, the product adopts orange and green two-color structure, compared with single-layer PPR pipe, double-layer PPR pipe has higher strength, better pressure bearing and shading, and can be installed indoors and outdoors. Diamond series pipes are divided into cold water pipes and hot water pipes, the pressure bearing capacity of hot water pipes is stronger, and both cold and hot water can be used, but the price of 16.4 yuan per meter is also more expensive, and the cold water pipe can only transport cold water, and the price is 9.99 yuan, which is relatively cheap.
 
The two-color PP-R water supply pipe of Liansu porcelain core series is made of imported raw materials, and the exclusive porcelain white technology also makes the inner wall of the ceramic texture very smooth, with low resistance to the conveying fluid, no scaling, reducing the breeding of bacteria and algae spots, and will not cause water pollution. It should be noted that the inner wall of the "porcelain core" tube advertised by various manufacturers is a ceramic-like plastic, not a real ceramic.
 
In addition to the more high-end double-layer pipe, Lesso entry-level single-layer PPR is also very good, the wall thickness deviation is small, convenient for hot melt connection, and the cost performance is very high, the price of cold water pipe is 4.6 yuan per meter, hot water pipe is 6.81 yuan per meter, because the price difference is not large, it is recommended to buy hot water pipes with better pressure bearing capacity, and the durability is stronger.
