FREEZING PREVENTIVE DISTRIBUTING WATER PIPE AND FLANGE JOINT
PROBLEM TO BE SOLVED: To provide a freezing preventive distributing water pipe showing superior cut-off performance and capable of positively preventing water leakage.SOLUTION: A freezing preventive distributing water pipe 1a comprises a pipe 10 including two resin pipes 11a, 11b spaced apart to each other and a joint 12 connecting two resin pipes 11a, 11b; a heat insulation material 20 covering the pipe 10; two resin outer pipes 31a, 31b arranged at an outer circumference of the heat insulation material 20 while being spaced apart with the joint 12 being held; and a heat melting and fixing resin sheet 32 wound in a cylindrical manner to cover the heat insulation material 20 positioned between the two resin outer pipes 31a, 31b over the two resin outer pipes 31a, 31b. The heat melting and fixing resin sheet 32 stores heaters molten and adhered to the two resin outer pipes 31a, 31b.SELECTED DRAWING: Figure 1
【課題】止水性が良好で漏水を確実に防止可能な凍結防止用配水管を提供する。【解決手段】凍結防止用配水管１ａは、互いに離間した２つの樹脂配管体１１ａ、１１ｂと、２つの樹脂配管体１１ａ、１１ｂを接続する継手１２とを有する配管１０と、配管１０に被覆された断熱材２０と、断熱材２０の外周に、継手１２を挟んで互いに離間して設けられた２つの樹脂外管体３１ａ、３１ｂと、２つの樹脂外管体３１ａ、３１ｂに亘って、２つの樹脂外管体３１ａ、３１ｂの間に位置する断熱材２０を覆うように筒状に巻き付けられた加熱融着用樹脂シート３２と、を備え、加熱融着用樹脂シート３２は、２つの樹脂外管体３１ａ、３１ｂに融着させるヒータを内蔵している。【選択図】図１
