【Haichuan Pipeline Construction】How to temporarily fix the gaskets for large-diameter flanges?
Thread Content
This post was last edited by Desert Fish on 2021-11-24 at 10:23. Since the release of GBT 38343-2019, the methods of using tape and lubricant for temporary fixing are no longer allowed. What convenient and effective methods do people have for installing gasketing with large diameters, such as in heat exchangers?
It seems there’s no good solution; it’s better to tighten the bolts first before putting it in
There are many methods; for distances within 1 meter, a steel ruler can be used, and the same method can also be applied for longer distances. For reference.
Thank you; I found a way – using PTFE tape wrapped around the bolt hole will also work
GBT 38343-2019 Technical Specifications for the Installation of Flange Connectors: \"Flange connectors for pressure-bearing equipment\" apply only to pipe flanges; the flanges on the equipment itself are not subject to these restrictions
Great post; I’ve now collected this series. Summary post for the [HaiChuan Pipeline Construction] series: https://bbs.hcbbs.com/thread-3272979-1-1.html (Source: HaiChuan Chemical Forum)
No need,,, just build a bridge to guide it into place first.
