Welding Semi-Rigid Centralizer
Tlhaloso
The welded semi-rigid centralizer ke sehlahisoa sa phetoho seo re se hlahisitseng haufinyane. Ho fapana le meralo ea setso, re sebelisa likarolo tse ikhethileng tse entsoeng ka lisebelisoa tse fapaneng ho fokotsa litšenyehelo tsa thepa ha re ntse re boloka ts'ebetso ea maemo a pele. Sehlahisoa sena se na le ts'ebetso e ntle haholo le ts'epahalo, 'me se khona ho mamella matla a maholo a radial le ho hlaphoheloa ho tsoa ho micro deformation. Ho phaella moo, sehlahisoa sena se na le mefuta e mengata ea lisebelisoa, 'me se loketse haholo ho sebelisoa liindastering tse kang oli le khase, k'hemistri le merafo. E ka ntlafatsa ts'ebetso ea ho cheka, ea ntlafatsa botsitso ba seliba, le litlamorao tsa samente, ka hona, ea lelefatsa bophelo ba liliba tsa oli.
Tšobotsi e hlahelletseng ea "welded semi rigid centralizer" ke ts'ebeliso ea likarolo tse cheselitsoeng tsa lisebelisoa tse fapaneng le moralo oa arc e khethehileng e habeli. Mokhoa ona o mocha ha o fokotse litšenyehelo tsa thepa feela, empa hape o tiisa ts'ebetso e babatsehang le ts'ebetso. Moralo oa liqha tse peli o lumella centralizer ho mamella likhatello tse phahameng le mathata ho ikamahanya le maemo a thata a ts'ebetso.
Sehlopha sa rona se entse liteko tse pharalletseng tsa li-welded semi rigid centralizer mme se fumane liphetho tse ntle haholo. Sehlahisoa sena ha se khone ho mamella matla a maholo a radial, empa hape se na le bokhoni ba ho hlaphoheloa ho tloha ho micro deformation, e phethang karolo ea bohlokoa haholo ts'ebetsong ea indasteri. Ntle le moo, sehlahisoa se boetse se bonolo ho se kenya, ho fokotsa nako, le ho ntlafatsa tlhahiso, ho etsa hore e be khetho e ntle ka ho fetisisa ea ho ntlafatsa ts'ebetso le ho laola litšenyehelo.
Ka hona, haeba u batla centralizer e ka fanang ka ts'ebetso e ntle ha o ntse o laola litšenyehelo, centralizer ea rona ea welded semi rigid centralizer e tla ba khetho ea hau e nepahetseng. Ka kopo ikopanye le rona kajeno ho ithuta haholoanyane mabapi le hore na lihlahisoa tsa rona li ka u thusa joang ho fihlela lipheo tse nepahetseng tsa ts'ebetso.
