摘要： A pipe coupling for coupling adjacent pipe ends of a pair of pipes includes a sleeve, a sealing gasket operatively coupled with the sleeve adjacent an open end of the sleeve, and a clamping element for compressing the sleeve or the sealing gasket into tightened engagement with one of the pipe ends. The clamping element includes two bolt flanges nominally spaced apart by a gap and a double threaded fastening bolt with two external threaded portions, which engage with two corresponding fastening nuts having right-hand thread and left-hand thread, respectively. Accordingly, when the fastening bolt is rotated, both the fastening nuts move towards or away from one another, thereby rapidly moving the bolt flanges to shrink the gap and compress the clamping element or to expand the gap. As such, less time and labor are required to operate the pipe coupling in the field.

摘要： A pipe coupling for coupling adjacent ends of a pair of pipes includes a sleeve, a split-ring gland positioned around one of the ends of the sleeve, and at least one annular gasket positioned within the split-ring gland and configured to be compressed by the split-ring gland for sealing one pipe end to the sleeve. The split-ring gland includes two partially circular gland members with spaced ends defining a gap. The pipe coupling includes an armor positioned to span the gap between the spaced ends to provide a generally closed annular periphery about the gasket. The armor includes a corrugated portion having a plurality of corrugations engaging the split-ring gland and the gasket during compression of the gasket. The armor is cold formed to improve structural strength and durability.

摘要翻译：用于联接一对管道的相邻管端的管接头包括套筒，与套筒相邻的套筒与套筒的开口端可操作地连接的密封衬垫，以及用于将套筒或密封衬垫压紧到一个紧固件中的夹紧元件的管端。夹紧元件包括标称间隙的两个螺栓凸缘和具有两个外部螺纹部分的双螺纹紧固螺栓，其分别与具有右旋螺纹和左旋螺纹的两个对应的紧固螺母接合。因此，当紧固螺栓旋转时，两个紧固螺母朝向或远离彼此移动，从而快速移动螺栓凸缘以收缩间隙并压缩夹紧元件或使间隙膨胀。因此，在现场操作管接头需要较少的时间和劳动。
