Ukukhiqiza Ipayipi Lokubhoboza Elifushane lase-China

Incazelo emfushane:

Ubude: Ubude busuka kumafidi ayi-5 kuye kwayi-10.

Ngaphandle Ububanzi (OD): I-OD yamapayipi okubhoboza amafushane ngokuvamile ihluka phakathi kwamayintshi angu-2 3/8 kuya ku-6 5/8 amayintshi.

Ukuqina Kwezindonga: Ukuqina kodonga lwalawa mapayipi kungahluka kakhulu kuye ngempahla yepayipi kanye nezimo ezilindelekile zembobo.

Material: Amapayipi okubhoboza amafushane enziwe ngensimbi enamandla amakhulu noma izinto ezixubile ezingamelana nemvelo enzima yokumba.

I-Tool Joint: Amapayipi okubhoboza ngokuvamile anamajoyini amathuluzi kuzo zombili iziphetho. Lawa majoyinti amathuluzi angaba yizinhlobo ezahlukene ezifana ne-NC (Numeric Connection), IF (I-Internal Flush), noma i-FH (Imbobo Egcwele).

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Incazelo:

I-Hardbanding: Amalunga amathuluzi futhi ngezinye izikhathi umzimba wepayipi lokubhoboza elifushane ungenziwa ibhande eliqinile ukuze kukhuliswe ukumelana nokuguga nokugqwala.

Qeda ukuxhumeka: Izixhumi ezigcinayo ngokuvamile ziyizixhumanisi ze-API ezivumela ipayipi ukuthi lihlanganiswe nezinye izingxenye kuchungechunge lokubhoboza.

Ibanga: Ibanga lepayipi lokubhoboza elifushane lisho amandla nokuqina kwepayipi. Ibanga livame ukunqunywa amandla esivuno sezinto ezibonakalayo.

Incazelo:

Ipayipi lokubhoboza elifushane liyithuluzi lokulungisa ubude besikhawu sethuluzi lokubhoboza ukuze lifinyelele inhloso ethile yobuchwepheshe ngesikhathi sokumba. Ngokusho kokuma kwehlombe, ihlukaniswe ibe yisakhiwo sehlombe esithelekile kanye nesakhiwo sehlombe esiqondile.

Imikhiqizo yochungechunge lwamapayipi okubhoboza iDemo isetshenziselwa ikakhulukazi ukusebenziseka kalula kwe-oilfield ngamakholomu amapayipi okubhola. Yenziwe ngensimbi yokwakheka kwe-alloy enamandla amakhulu ngemva kokwelashwa kokushisa, ukusebenza komshini, nentambo ehlanganyelwe ihambisana nezidingo ze-API.
