Analysis of production and marketing status of PVC pipe

Production and marketing status analysis of PVC pipe production line

(1) PVC resin is the pillar product of chlor alkali industry in China, and it must be developed. Caustic soda is an important basic chemical raw materials, a chlorine production process of caustic soda, to solve the problem of the use of chlorine, must develop the Pvc resin consumption of chlorine, so Pvc is a pillar industry in chlor alkali industry, still need further development.

(2) PvC resins consume relatively little oil resources. The production of 1tPVC resin consumes 0.53t ethylene, while the production of 1tPE resin consumes 1.05 - 1.10t ethylene. This is a serious problem for China, which has a serious shortage of oil resources and a rising demand. From the perspective of energy conservation, the development of PVC is also of great significance.

(3) PVC - U plastic pipeline conforms to the direction of national industry development. Compared with the traditional cast iron pipes, PVC - U plastic pipes have the advantages of saving energy and protecting the natural ecological environment. Therefore, they are paid more attention to. According to the "national chemical building materials industry" fifteen "plan and the 2010 development plan", to promote the application of plastic pipe will develop, key varieties to PVC and PE.

By 2010, the new construction, renovation and expansion project, building drainage pipe 80% using plastic pipe, construction of rainwater drainage pipe with 70% plastic pipe, plastic pipe by 30% city drainage pipeline, building water supply, heating and hot water supplying pipe 80% by plastic pipe, city water supply pipeline (DN400) using 70% plastic pipe, water supply the 70% pipe plastic pipe, city gas pipeline using 60% plastic pipe (in low-pressure pipe), building wire protecting pipe with plastic pipe 90%. Therefore, the PVC - U pipeline has been listed as the development direction of the national industrial policy.

In March 18, 2004, the Ministry of Construction issued "on the release (the Ministry of construction application and restrictions on the use of Technology) Notice" (Ministry of Construction No. 218th), the plastic pipe system, urban and rural water supply drainage plastic pipe plastic water supply pipe system and building drainage system, plastic pipe construction system to recommend the use of plastic pipe, pipe - including PVC U the (PVC - U for drinking water pipeline requires the use of non lead salt stabilizer).
