ABSTRACT:
A removable connector for use between angled, immovable high pressure lines is disclosed. The connector utilizes a tubular elbow portion having a mating flange on each end and an adapter which mates with one of the elbow flanges. The remaining elbow flange mates with a flange at the end of one of the high pressure lines and the free end of the adapter mates with a flange at the end of the other high pressure line. The mating flange surfaces are frusto-conical in shape and corresponding frusto-conical seal rings are placed between the mating surfaces. The elbow and adapter are adapted to have their respective ends placed at the pipe flanges and their bodies rotated toward each other until their opposite ends mate with each other. The flanges are then bolted together and tightened to ensure sealing engagement and bring the elbow and adapter into alignment with the pipes.
