90度短半径弯头

An elbow is a pipe fitting installed between two lengths of pipe or tubing to allow a change of direction, usually a 180° or 90° angle, though 45° elbows are also made. The ends may be machined for butt welding (SW) or socketed welding(SW) etc.

大多数肘部都有短半径或长半径变体。当两端尺寸的尺寸不同时，配件称为还原弯头或减速器弯头。

肘部根据以下各种设计特征进行分类：

• 长半径（LR）弯头也被称为LR弯头 - 表示线径的半径为1.5倍
  • L/R 45°Elbow：长半径45度弯头将方向变为45度。
  • L/R 90°Elbow：长半径90度弯头将方向变为90度。
  • L/R 180°Elbow: Long Radius 180 degree return bend allows complete reversal of flow.
• Short Radius (SR) Elbowis also called SR elbow, – means the radius is 1.0 times the pipe diameter
  • Short radiu 45°Elbow：短半径45°弯头将方向变为45度。
  • Short radius 90°Elbow: Short Radius 90° elbow is same as LR90 except for the measurement between end of elbow to center line is 1 x NPS.
  • 短半径180°弯头: Short Radius 180° return bend allows complete reversal of flow
