I-Epoxy FRP Pipe Internal Heating Curing
I-epoxy fiber eqiniswe imigqa yepulasitiki ye-HP yepulasitiki kanye neshubhu le-downhole kukhiqizwa ngokuhambisana okuqinile nokucaciswa kwe-API. Umphumela wonyaka ufika ku-2000km ubude nobubanzi obusuka ku-DN40 kuye ku-DN300mm.
I-epoxy FRP HP surface line ine-API ejwayelekile yokuxhunywa kwentambo eyindilinga ende ezintweni eziyinhlanganisela, ukumelana kwayo nokugqoka kwenyusa impilo yokusebenza kwamapayipi.
Ishubhu ye-epoxy FRP ye-downhole iwuhlobo lokusebenza okuphezulu, amandla aphezulu aqinile epayipi le-FRP elimele ngokunembile ngemishini elawulwa yidijithali. Ubuchwepheshe bomoya obuqhubekayo be-fiber obuthuthukisiwe busetshenziswa ukuze kubonakale amandla e-tensile agculisayo adingekayo ezinhlelweni ze-downhole.
Ingcindezi yokusebenza ephezulu yemigqa yangaphezulu ye-HP ingu-31MPa kanti ishubhu le-downhole lingu-26MPa. Izinga lokushisa eliphakeme kakhulu le-ambient lepayipi le-aliphatic amine elaphelisiwe le-epoxy FRP lingu-85℃ kanye nepayipi le-amine eliphunga elipholile le-epoxy FRP lingu-110℃. Amapayipi asebenza ekushiseni okungu-150 ℃ ayatholakala ngokwesicelo samakhasimende.
Izici Eziyinhloko:
• Isisindo esincane, cishe i-1/4 yepayipi yensimbi;
• Ukufakwa okusheshayo nokulula ngaphansi kwazo zonke izimo zezulu futhi ngaphandle kwesidingo se-ejenti yokubopha;
• Ingaphakathi elibushelelezi, uketshezi oluhle kakhulu;
• Ukumelana nokugqwala okuqinile nempilo ende yokusebenza;
• Izindleko zokufaka eziphansi;
• Ukufakwa kwengcina nesikali.

Ipayipi Lensimbi Elingenamthungo Eligoqelwe ngokushisayo
Ulayini wokukhiqiza ipayipi lensimbi elingenamthungo eligoqelwe elishisayo usebenzisa ithubhu eligoqiwe le-Arccu-Roll elithuthukisiwe ukuze likhiqize i-casing, ishubhu, ipayipi lokubhoboza, ipayipi kanye namapayipi oketshezi, njll. Ngomthamo wamathani ayizinkulungwane eziyi-150 ngonyaka, lo mzila wokukhiqiza ungakhiqiza ipayipi lensimbi elingenamthungo. ezinobubanzi obungu-2 3/8" ukuya ku-7" (φ60 mm ~φ180mm) nobude obukhulu obungu-13m.

I-API Drill Pipe 3.1/2”-5.7/8” yokumba Amafutha / Igesi
Isingeniso Somkhiqizo: Inkampani yethu igxile ekukhiqizeni nasekudayiseni amapayipi ajwayelekile e-API okubhola uwoyela ane-OD esuka ku-2 3/8 kuya ku-5 1/2 kanye nebanga elisuka ku-E75 ukuya ku-S135. Futhi amapayipi okubhola asetshenziswa ikakhulukazi ekwakhiweni komthombo ojulile ophakathi nendawo, umthombo ovundlile, kanye nokufinyelela okunwetshiwe ohlelweni lokuhlola nokuthuthukiswa kukawoyela negesi. Ngezimpawu eziphelele zokuqedwa okuhle kwendawo, ukuguquguquka okuhle, ukubekezelelana komthelela okuphezulu, ukunamathela okuhle kakhulu kanye ...

Drill Collar-Slick futhi Spiral Downhole Pipe
Ikhola yokubhoboza yenziwe nge-AISI 4145H noma iqede ukugoqa ingxube yensimbi yesakhiwo, icutshungulwe ngokwezinga ngalinye le-API SPEC 7. Kuyo yonke inqubo yokukhiqiza ikhola yokubhoboza, idatha yokuhlola yokuhlolwa kokusebenza kwento ngayinye, kusukela kungenalutho lokusebenza, ukwelashwa kokushisa kuya kuntambo yokuxhuma kanye nenye inqubo yokukhiqiza, iyalandeleka. Ukutholwa kwamakholola e-Drill ngokuphelele njengokujwayelekile ngokwe-API. Zonke izintambo zithola ukwelashwa kwe-phosphatization noma i-copper plating ukuze kwandiswe ukuhlangana kwazo ...
