VINYL CHLORIDE RESIN PIPE AND METHOD FOR CONSTRUCTING VINYL CHLORIDE RESIN PIPE
To provide a vinyl chloride resin pipe having excellent fire resistance.SOLUTION: A vinyl chloride resin pipe has a tubular first layer containing vinyl chloride resin. When the vinyl chloride resin pipe is heated at 120°C for 20 minutes, an expansion rate, calculated by the following formula (1), is 5% or more and 20% or less. Expansion rate=(D2-D1)/D1×100 Formula (1). D1: outer diameter of vinyl chloride resin pipe before heating. D2: outer diameter of vinyl chloride resin pipe after heating.SELECTED DRAWING: Figure 1
【課題】耐火性に優れる塩化ビニル系樹脂管を提供する。【解決手段】本発明に係る塩化ビニル系樹脂管は、塩化ビニル系樹脂を含む管状の第１の層を備え、塩化ビニル系樹脂管を１２０℃で２０分間加熱したときに、下記式（１）により算出される膨張率が５％以上２０％以下である。膨張率＝（Ｄ２−Ｄ１）／Ｄ１×１００ ・・・式（１）Ｄ１：加熱前の塩化ビニル系樹脂管の外径Ｄ２：加熱後の塩化ビニル系樹脂管の外径【選択図】図１
