Work principle and purpose |
| Tighten the nut after the loosely put telescopic joint is mounted on the pipeline. The elastic seal, under the pressure of both nut and gland and relying upon the mutual inclination, is tightly pressed on the outside of the pipe to act as sealing and connecting. When temperature varies, the pipe can be telescopic freely at the joint; and, when the ground sinks and the ship vibrates and inclines, can make sure of non-leak with the seal so as to get the auto-compensation. |
 |
Used for completing with butterfly valve, gate valve, check valve and stop valve. Able to lower the project cost and effectively settle the difficult in mounting and removing the valve. Mainly for connecting both pipeline and valve and, fitted with a limiting bolt, able to prevent the telescopic joint from pulling off by the pipeline in case of a bigger external action force and the internal one caused due to hot-expansion and cold-shrink, leaving an unnecessary pipeline leak accident. |
