PP Fitting Wholesaler Introduced Current Situation

PP pipe introduced by PP fitting wholesaler has the characteristics of high temperature resistance, convenient pipe connection (heat welding, electric welding, pipe connection), and acceptable use. It is mainly used in farmland water delivery system, building water supply system, heating system and chemical pipeline system. According to pp pipe polymerization process conditions, it can be divided into homopolypropylene (PP-H), block copolymer polypropylene (PP-B) and random copolymer polypropylene (PP-R). Because the brittleness of PP-H pipes at low temperatures restricts its application, it has been gradually replaced by PP-B pipes and PP-R pipes in some applications. Among them, PP-B pipes are mainly used in cold water systems and above-ground heating systems, while PP-R pipes are more widely used. In addition to the simple characteristics of plastic pipes, PP-B and PP-R pipes also have the following characteristics: superior cleaning function, heat resistance, heat preservation and energy saving, convenient installation, reliable connection, materials that can be accepted and used, simple equipment requirements, and production technology Concise and easy to control, the pipeline layout is free. Since my country issued a decree in 2000 to prevent the use of galvanized pipes as water supply pipes in newly built houses, polypropylene pipes and polyethylene pipes have been greatly opened. Among them, PP-R pipes are the third generation of modified pp pipes pioneered in Europe in the early 1990s. The long-term hot water static pressure life of pp pipes is much faster than that of PP-H and PP-B, and the pressure resistance, low temperature resistance and service life have improved. With the rapid development of my country's economy, the consumption of PP-R pipes has also increased significantly, and the market has made rapid progress. The Ministry of Construction of my country has taken PP-R pipes as the main point to implement the three most new types of plastic pipes that are the first to promote, so it has gained momentum in recent years. In 1997, there were only a few PP-R pipe manufacturers in my country, no more than ten in 1998, 30 in 1999, and the number of PP-R pipe manufacturers at the end of 2000 is estimated to have reached about 70, with more than 130 production lines. , The production talent is more than 50,000 tons, and the theoretical output is short of 20,000 tons. Because pp pipe production companies have blindly launched, the pipe talent is severely surplus, which has caused vicious competition, decreased quality, and presented many problems, which constituted a very bad social impact. In the past two years, after the country has sorted out and promulgated the corresponding pipe quality and construction specifications, the profession is embarking on a healthy and open road. At that time, the domestic production capacity was about 300,000 tons, and the output was about 140,000 tons. In recent years, the opening of PP plastic pipes has been excellent, and it has the potential to replace cross-linked polyethylene pipes and cross-linked polyethylene aluminum composite pipes. In my country, from 2001 to 2010, the annual demand for indoor cold water pipes was about 300 million meters, the demand for hot water pipes was about 100 million meters, and the demand for heating pipes was about 200 million meters. The demand is about 100 million meters, the demand for floor radiation heating pipes is about 400 million meters, and the annual demand for cold and hot water pipes for solar water heaters is about 20 million meters. In addition, in many hotels and hotels in my country, the average annual hot and cold water pipeline renewal volume reaches 20 million meters. The annual pipeline demand for construction and renovation projects is about 20 million meters. The annual demand for industrial pipelines is about 20 million meters. The demand is about 20 million meters. According to the above calculations, the annual demand for pipeline construction in my country from 2001 to 2010 was about 1.2 billion meters. If pp pipes are calculated at a rate of 30% of the market, the annual market demand will reach 300-400 million meters. Therefore, it can be estimated that pp pipes will be opened at a high speed in the next 10-20 years, and its market potential is huge.
