SMK adjustable balanced –type abrasion resistant dual-core shrinking hole

2018-07-10

        SMK adjustable balanced –type abrasion resistant dual-core shrinking hole is a mature product which is developed and improved based on single-core and adjustable shrinking hole and has been applied for utility model patents in 2004. Patent: ZL2004 2 0028010.8

       Adjustment theory:

       Symmetrical dual-core flashboard of shrinking hole do reciprocating movement from pipe center to out to adjust opening area, so the pipeline flow of high-speed wind always be able to be kept to flow in the center of the pipe. In this way, to basically eliminate abrasion and reduce the flow resistance for the side of wall, thereby prolonging the service life of pipelines.

        Technical parameters:

        Minimum flow cross-sectional area:25%.

        The largest circulation cross-sectional area:100%

        ZG35CrMnSiMoRe Flashboard material:ZG35CrMnSiMoRe

        Joint mode :welded or flanged

        Manufacturing standard:Q/321282HZC05-2016
