ABSTRACT:
An alignment tool for use with a pipeline mounting flange having a raised face flange to self center two opposing raised face flanges during a fluid pipeline mounting operation. A plate-like ring with outwardly diverging spring fingers with an inner diameter slightly larger than the outer dimaeter of the raised face flanges is mounted on the pipeline mounting flanges so the fingers are adjacent the raised face flanges. Tightening the flanges throughbolts moves the flanges together while the spring fingers engage the riased face flanges and maintain the raised face flanges in self centering alignment. A flange seal gasket is captured within the plate-like ring.
