Hona jwale, diphaephe di sebediswa haholoholo bakeng sa ho tsamaisa oli le khase diphaepheng tse hole. Diphaephe tsa tshepe tsa diphaephe tse sebediswang diphaepheng tse hole di kenyeletsa haholohololiphaephe tsa tšepe tse phuthetsoeng ka har'a arc tse spiral tse qoelitsoeng ka har'a arcle liphaephe tsa tšepe tse koahetsoeng ka arc tse nang le mahlakore a mabeli tse nang le seam e otlolohileng. Hobane phaephe e koahetsoeng ka arc e entsoeng ka arc e entsoe ka tšepe e strip 'me botenya ba lebota la eona bo lekanyelitsoe, ntlafatso ea boemo ba tšepe e lekanyelitsoe ke kalafo ea mocheso ea thepa. Ho phaella moo, ho na le mefokolo e meng e ke keng ea hlōloa ea phaephe e koahetsoeng ka arc e nang le spiral, joalo ka weld e telele, khatello e kholo e setseng le ts'epo e fokolang ea weld. Ka litlhoko tse ntseng li eketseha tsa liphaephe tsa tšepe tsa phetisetso ea oli le khase, ha li sa sebelisoa libakeng tse nang le baahi ba bangata le libakeng tse nang le litlhoko tse phahameng tsa ts'epo, leliphaephe tse otlolohileng tse nang le bophara bo bohololi ntse li nkela liphaephe tse spiraleng sebaka butle-butle.
Morao tjena, Chaena e potlakisa ntshetsopele ya oli le khase Leoatleng la Bochabela la Chaena. Ka ntshetsopele ya tshebediso ya oli botebong ba lewatle, phaephe e beilweng fatshe ho lewatle e angwa ke matla a kopaneng a kgatello, matla a tshusumetso le matla a kobehang, mme ketsahalo ya ho batalatsa e ntse e bonahala, e leng kgokelo e fokolang ya phaephe e welditsweng ka spiral. E le ho ntlafatsa bokgoni ba ho tsamaisa phaephe le ho netefatsa hore phaephe ya ka tlasa lewatle e hola ho ya leboteng le teteaneng, phaephe ya ka tlasa lewatle e sebedisa phaephe e welditsweng ka ho otloloha haholo. Ka hona, ha e bapiswa le phaephe e welditsweng ka spiral, phaephe e welditsweng ka ho otloloha e na le ho nepahala ho hoholo le ho wellisa habonolo ha tokiso, kahoo ho tloha ntlheng ena, phaephe e welditsweng ka ho otloloha le yona ke kgetho ya pele.
Mechine, kaho, indasteri ea lik'hemik'hale le liindasteri tse ling li hloka liphaephe tse otlolohileng tse phuthetsoeng. Hona joale, lesoba le ka hare la setulo sa valve le etsoa ka mochini ka mor'a ho betla indastering ea mechini, e leng se jang nako e ngata, se jang thepa e ngata le se jang thepa. Haeba ho sebelisoa phaephe e otlolohileng e nang le marako a teteaneng e phuthetsoeng ka seam e otlolohileng, e tla ba theko e tlase haholo. Ho phaella moo, ka lebaka la litlhoko tsa thepa ea mechini ea ho thibela ho batalla, ke liphaephe tse otlolohileng feela tse phuthetsoeng tse phuthetsoeng tse phuthetsoeng tse sebelisoang bakeng sa ho haha liphaephe; Phaephe e otlolohileng e phuthetsoeng e boetse e lebelletsoe ho sebelisoa bakeng sa liphaephe tsa lik'hemik'hale.
