In recent years the economical booming change was fast, last year at the beginning of the whole world was also in the currency expansion concealed worry, in the second half of the year transformed the global deflation rapidly, the original material price fell over 70% by the peak, the domestic electronic spare-time university had the unpaid holiday, the unemployment rate surges upward. But the government will expand the domestic demand continually, the steel and iron price stops by most recent several year high spot rapid reverse to the near future falls returns to stability, lets building industry have the superiority in the cost. Generally in the tradition the fire water pipe road mostly uses the galvanization steel pipe, the price fluctuations and in the construction process must use the welding or Che Ya greatly processes, also in the transporting is not convenient, meets great caliber Shi Zuoshi must rely the crane to assist to transport.
In recent years American raw material business developed 'the fire protection rank chlorination polyvinyl-chloride (CPVC)' the product, utilized in the fire tubing domain, substituted for the steel pipe product gradually. This research namely aims at this product discussion domestic building industry to the CPVC product understanding degree and the purchase wish, and further provides for the CPVC product business agent takes the marketing reference the basis.
The findings discovered that a domestic product was still strange regarding this, although the fire prevention Controlling organization has checked one of for fire aqueous system tubing materials, but city occupying rate and the steel pipe product comparison are not as before high.
