Claims (1)

【実用新案登録請求の範囲】[Scope of utility model registration request] 粒状物を空気圧送する管路の曲り部を形成する
曲管であり、上流管路に接続される曲部と下流管
路に接続される直部とから成り、曲部管壁で曲管
の湾曲方向の外側に位置する部分を厚肉に偏肉さ
せて形成するとともに、直部管壁で曲管の湾曲方
向の内側に位置する部分を厚肉に偏肉させて形成
したことを特徴とする耐摩耗性曲管。 A bent pipe forms a bent part of a pipe for pneumatically transporting granular materials, and consists of a bent part connected to the upstream pipe and a straight part connected to the downstream pipe. The pipe is characterized in that the part located on the outside in the direction of curvature is formed with a thick uneven thickness, and the part of the straight pipe wall located on the inside of the curved pipe in the direction of curvature is formed with a thick uneven thickness. Wear-resistant bent pipe.
