Marine pipeline quick connector expansion joint
The steel gland type loose sleeve expansion joint is a kind of marine joint. It is a loose sleeve expansion joint based on the original performance, with a limit device. The expansion of the gland type loose sleeve limit expansion joint is locked with double nuts. In this way, once the expansion joint exceeds the free limit of the expansion sleeve, the pipeline can work normally. This can effectively ensure the safe operation of the gland type loose sleeve limit expansion joint pipeline, especially suitable for the selection of vibration or certain slope and turning.
Performance of quick connector
