Semipressurized rainwater system


As for the half pressure flow roof drain and half pressure flow heating roof drain, there are such three kinds of outlet pipe diameters as of DN80, DN100 and DN150. It is different from the traditional Type-87 Gravity Roof Drain, which can not only be installed on the concrete roof, but also be applicable for the steel-structured roof gutter. The improved pressure plate and fastening bolt of the roof drain are both made of the stainless steel materials. And there are such two kinds of short pipe materials as of the stainless steel and HDPE. The fairwater is moulded by the diecasting of aluminum-silicon alloy, with the sealing ring moulded by the compression of silicon rubber. The service life of the half pressure flow roof drain could reach 50 years.
