API 5CT OCTG tubing Manufacturer

Inkcazelo emfutshane:

I-API 5CT OCTG iityhubhu ngumjelo osetyenziselwa ukuthutha i-oyile ekrwada okanye irhasi yendalo ukusuka kulwakhiwo lwemveliso ukuya kumaziko omgangatho webala ukuze kusetyenzwe emva kokuba ukugrunjwa kugqityiwe.Ngethuba lenkqubo yokukhupha, i-tubing ye-OCTG kufuneka imelane noxinzelelo kwaye kufuneka yomelele ngokwaneleyo ukuxhathisa imithwalo kunye nokuguqulwa okuhambelana nokuveliswa kunye nokusebenza.Ukongeza, iityhubhu ngokubanzi zilinganiswe ukwanelisa amaxabiso alindelekileyo emveliso yeoli negesi.Kungenxa yokuba ukuba i-tubing inkulu kakhulu, siya kuba nempembelelo yezoqoqosho ngaphaya kweendleko ze-tubing yeoli kunye negesi ngokwayo, nangona kunjalo, ukuba i-tubing ye-API incinci kakhulu, iya kuthintela ukuveliswa kweoli okanye igesi, kwaye ukuba izinto ziqhubeka ngale ndlela. iya kuba nefuthe ekusebenzeni koqoqosho okulandelayo kwequla.Ngokuqhelekileyo, i-tubing yenziwa ngendlela efanayo ne-casing, ngaphandle kwenkqubo eyongezelelweyo eyaziwa ngokuba "i-upsetting" esetyenziselwa ukuqinisa imibhobho.
