Reason for selection:
Polyvinyl chloride
is a common material for water-supply pipes of apartment complexes but the
applicant has recently developed a construction method using stainless steel
pipes for sections of common use. The new method makes it possible to change
the lengths of vertical pipes according to storey heights and to use
smaller-diameter pipes on account of larger flow coefficient of stainless steel
pipes. These advantages substantially offset higher material costs of stainless
steel.
In addition, this method
has been adopted by the government as a model project for super-durable
residences and is expected to contribute to future supply of good durable
houses as social stock and to reductions in industrial wastes and CO2
emissions.
The new method is expected to expand demand for stainless steel in the
ABC sector. |
