APPARATUS FOR DRAWING CHECK ON PIPE

摘要

An apparatus is provided to draw check on a curved pipe in an accurate and quick manner by using a center pole and an angle gauge and a drawing unit joined to the center pole. An apparatus(1) for drawing check on a curved pipe includes a center pole(10), a curved pipe joint unit(20), an angle gauge(30), and a drawing unit(40). The curved pipe joint unit is branched from the center pole, and tightened onto a curved pipe. The angle gauge has a center matched to the center of the central pole. The drawing unit is joined to the center pole such that the drawing unit is rotatable. The curved pipe joint unit includes a first curved pipe joint portion(20a) and a second curved pipe joint portion(20b) which have adjustable angles.
