METHOD FOR CONSTRUCTING HOT WATER SUPPLYING PIPE
To provide a method for constructing a hot water supplying pipe that can reduce a residual stress of a bent portion of piping even when plumbing in a bent state, and can improve crack resistance of the hot water supplying pipe after construction.SOLUTION: The method for constructing a hot water supplying pipe comprises constructing a hot water supplying pipe 2 containing polybutene. The method for constructing a hot water supplying pipe has a piping step for plumbing the hot water supplying pipe 2 in the bent state and a heating step for heating a bent portion 2c of the hot water supplying pipe 2 at 130°C or more and 200°C or less.SELECTED DRAWING: Figure 2
【課題】屈曲させた状態で配管しても、当該屈曲箇所の残留応力を小さくすることができ、施工後の給水給湯パイプの耐クラック性を向上させることができる、給水給湯パイプの施工方法を提供する。【解決手段】ポリブテンを含有する給水給湯パイプ2を施工する、給水給湯パイプの施工方法である。給水給湯パイプ2を屈曲させた状態で配管する、配管工程と、給水給湯パイプ2の屈曲箇所2cを、１３０°Ｃ以上、２００°Ｃ以下で加熱する、加熱工程と、を有する。【選択図】図２
