Hello Everybody,

I am working on a project, storage facility for hydrocarbons. At dyke wall penetrations Client is asking to use Link-Seal as a Sealant. Dyke is for 3 API tanks. Hence from the outermost tank to reach dyke, pipe has to travel some distance. I asked Link Seal vendor to provide information on allowable Lateral, Axial angular movements & coefficient friction to determine location of stopper in dyke wall piping. But Vendor do not have any data about this. But wisely he said” Link seal is a seal & not a movable plug.” Hence to provide no movements at Link Seal I may have to give additional flexibility to 36” 60deg.C.operating pipe.Inturn Link seal is dictating pipe routing.

Does any of forum member have previously used link seal at Dyke wall & if so what are the considerations for analysis & assumptions

Thank you & Regards

Can Link seal vendor provide lateral and angular stiffness at the joint?

Please forgive me if this seems another stupid Q.

My experience has been that the manufacturers of such seals will not provide the data needed to model their seal. One approach I've used is to bound the analysis assuming the seal acts as an anchor in one case, and as a "flexible" restraint for another case. Judgement is necessary for the flexible case to assure the assigned restraint flexibility exceeds the anticipated seal's flexibility.
