Development and the Outlook of PVC Pipe Fitting

Development history: PVC profile products have experienced the introduction period and the rapid development period, from the perspective of time, they can be defined as the 1980s-mid-1990s and 1995-2002 respectively. After 2003, the PVC profile industry has entered a transition period. In the introduction period of products: manufacturers generally pursue low cost, simplify the profile section of doors and Windows, and the formula is heavily filled with calcium carbonate, resulting in very low product performance, and many quality problems affect the promotion of products.Since 1995, a number of enterprises with strength, began to digest and absorb the technical essence of foreign European profiles, developed their own doors and Windows series, become the leading domestic plastic doors and Windows, promote the technical update and development of doors and Windows, but also make the whole industry to get unprecedented development and high-speed growth. Into the product maturity, since 2003, many disadvantages, high profit margin leads to blind investment, make the industry comprehensive capacity of nearly 3 million tons, much higher than the market demand; many new investors do not from product innovation, technology innovation, but simply imitate, even corners, fake, industry market competition in an unhealthy state. The rising price of raw material market exacerbates this non-healthy competition, making some enterprises operating in trouble, and stop production or semi-production state.

PVC profile industry status quo: the industry also exist more production enterprises (nearly 400), small production capacity (about 2.8 million tons), small demand (in 2003 national profile sales 1.2 million tons), capacity can not fully play the contradiction, annual output of more than 20000 tons of less than 10 enterprises, uneven product quality level, inferior products still have a market, industry quality technology standard is too low, is not conducive to technological progress, lead to substitute aluminum comeback. The high-end market (30%) is occupied by foreign brands, and the middle and low-end market is unprofitable and highly competitive, and the final pattern has not yet been formed.

The current situation of PVC Pipe Fitting industry: As one of the products of technological development, PVC Pipe For Irrigation is within reach in daily life. In Europe, plastic tubes grew by 8% from 1980 to 1990, and there were 3.5 million tons of production in 2001, of which PVC tubes accounted for 60%. The United States produced 1.6 million tons of plastic pipes in 1985, and about 3.6 million tons in 1999, of which PVC Pipe For Water accounted for 78%. China's first UPVV outlet expansion pipe was born in Shenyang Plastic Factory in 1983, and since then, Chinese mainland has had the production capacity of PVC pipes and drainage pipes. The late 1990s was a period of rapid development of the Chinese mainland PVC pipeline. During this period, some factories with an annual capacity of more than 50,000 tons have been completed and put into operation, and there are more than 30 PVC pipeline factories with a production capacity of more than 10,000 tons. The annual production capacity of plastic pipes is 2 million tons.

The PVC-O tubes have been used in countries such as the UK, France, the Netherlands, Portugal, the USA, Australia, South Africa and Japan for many years. The United States, Australia and other countries have released product standards for PVC-O, and the International Standards Organization has also published PVC-O standards-ISO / DIS 16422-2006.

Development trend: The PVC pipeline has been highly praised by the engineering industry for its light weight, corrosion resistance, high pressure resistance strength, safety and convenience. In recent years, driven by the rapid development of domestic economy, China's PVC pipeline has developed very rapidly. Industry analysts pointed out that: supported by PVC perfect supporting industry chain and domestic raw materials, PVC pipeline production accounted for 55% of the total. In recent years, the PVC pipeline market has been affected by various factors. The decline of PVC pipeline market share is mainly included in three main aspects:1: The PVC pipeline market is impacted by PE, PPR and other plastic pipelines, and has seized a certain market share;

2: The prohibition of lead-containing stabilizer in PVC pipes in contact with food products has a certain negative impact on the development of PVC pipeline;

3: At present, the development of PVC pipeline is in a period of rapid development, and the production capacity of the industry is expanding. In order to seize the market and reduce costs, many small and medium-sized enterprises fill the formula, which affects the image of the PVC pipeline industry, directly affects the PVC market share, and accelerates the loss of PVC market share.

But overall, while the share of the PVC pipeline is declining, it still dominates the plastic pipeline market. And the attractive prospect of the plastic pipeline industry is still a bright spot driving the development of the PVC pipeline industry.

  Development status: Since the early 1980s, the country has vigorously promoted the application of upvc management, and formulated a series of policies, systems, standards, but also accumulated a lot of experience. Today, it has a perfect product standards, testing methods and testing means, construction engineering technical specifications, so as to unify the product specifications and quality indicators, to achieve the product interchangeability. This shows that the development of pvc water supply pipeline has entered the mature period, and the product quality and construction quality are guaranteed, thus ensuring the use effect of pvc water supply pipeline.The international standard for pe pipes (ISO4427) for water supply was not officially released until 1996. China compiled the national standard GB / T13663 according to ISO4427 in 1999, and it was released and implemented in 2000, but the standards and engineering technical specifications of pe pipe fittings are still continuing to be improved. This shows that the quality of domestic pe pipe is not stable, and the pipe fittings are not perfect, so it cannot ensure the quality of production and construction.

Outlook: China's production capacity of plastic pipelines reaches 3 million tons, mainly including PVCPipe Fitting, PE Pipe Fitting and PP Pipe Fitting, among which PVC pipelines are the plastic pipelines with the largest market share, accounting for nearly 70% of the plastic pipelines. PVC pipe production line more than 1600. The annual production capacity is more than 2.5 million tons, and in 2003, the annual output of PVC pipeline (pipe fittings) reached more than 1.2 million tons. In Plastic Fitting, PVC share is 70%, PE 25%, PP-R 4% and others 1%. Although the rapid development of PVC pipeline has attracted many enterprises to invest in this industry, among many domestic manufacturers (more than 2,000), only more than 70 enterprises with annual output of 10,000 tons, and more than 20 enterprises with annual output of more than 30,000 tons and 60% of the output of the industry. On the whole, there are more small caliber and low value added pipeline enterprises, and fewer large caliber and high technology content. The processing capacity distribution of PVC pipe is not unreasonable.The processing capacity of small and medium-sized enterprises is mainly concentrated in PVC drainage pipes, while a large number of non-standard pipes still flood the market, leading to disorderly and chaotic market competition. In some traditional areas of PVC plastic pipes, PE and PP-R substitution momentum. The encroachment of other varieties on market share and the prohibition of lead stabilizer in PVC pipes in contact with food products will have a certain negative impact on the development of PVC pipelines. In particular, PVC raw materials generally account for 70-80% of the total cost, and the price change of the main raw material PVC has a significant impact on the enterprise. After 1998, production capacity expansion, market competition intensified, price fell, PVC raw material prices increased, and industry profits decreased. Many small and medium-sized enterprises cut corners and build up shoddy goods, struggling to survive. The PVC pipe itself is a large waste of transportation and loading space, coupled with the introduction of new road traffic regulations, to further improve the transportation costs.
