Ukugubha amapayipi zenzelwe imishini kahle

Ukugubha amapayipi zenzelwe imishini uwoyela negesi imithombo. Besebenzisa imishini enjalo yakhiwa futhi phansi Borehole idwala ahlabayo ithuluzi idluliselwa ku torque adalwe umthwalo (Axial) ukuze insimbi, ngabondla onomfutho emoyeni noma isixazululo egeza ebusweni. ukukhiqizwa yabo mhlawumbe eyenziwa ejwayelekile GOST № 50278-92. Ngokusho mthethonqubo, imikhiqizo ekhiqizwa kusukela ngensimbi, kwakheka ngendlela Seamless futhi ngatshala imikhawulo lapho basuke eziphothene sivala.

Drilling amapayipi angase abe izinhlobo ezahlukene izingxenye etshalwe ezifaka lokubikezela kwangaphakathi, yangaphandle noma kuhlanganiswe (ezikhonjiswe njengoba px, neMo noma i-PC, ngokulandelana). Articles px ekhiqizwa enobubanzi obungu elingaphandle kusuka 73 kuya 101,6 mm, udonga ukujiya kusuka 8.4 kuya 11.4 mm, isisindo ibalwa elilodwa imitha esibushelelezi tube amabanga kusuka mayelana 14 kuya ku-22 kg.

I diameters ipayipi sokuprakthiza ifinyelela isigaba PC ngokulinganisa 139,7 mm (inani eliphansi elilingana 114,3 mm). A ipayipi nge kokwehla yangaphandle (MB) abe ezincane enobubanzi obungu ngokuhambisana GOST ngenhla (127 mm). Ngaphandle ubukhulu ukuze ipayipi okuzisholo uyazicabangela nemingcele ezifana ububanzi we yokukhiya (ekhiqizwa ngokusho GOST 27834) futhi ububanzi we ngokuhlanganyela weld, kuhlanganise kwangaphakathi futhi ububanzi we silo. Enye ipharamitha okubalulekile ubude okumelelwe amaqembu amathathu: kusukela 5.9 amamitha ukuba 6.3, kusukela ngomhlaka 8 kuya 8.6 m futhi kusukela amamitha 11.9 kuya 12.5. ukukhiqizwa Modern angakhiqiza amapayipi kokubili obuphelele ezinkulu nezincane, kodwa kulokhu bona zehlukile kwezilinganiso ezivunyelwe.

Qualitative sokuprakthiza ipayipi kufanele kwenziwe ukuze ezindaweni zawo awuzange aqhephukile, fibre izinyanda, amagobolondo, kanye nezinye zamehlo. Ukuze ulungise la maphutha ungakwazi kuphela kanye eksisi tube, ukubekwa uphawu, futhi Welding Crimping inkinga ezindaweni abavunyelwe, bayazibuza nje ukuhlanza noma unciphise.

Womshini sokuprakthiza ipayipi ahlelwe ukuze lo ingxenyenamba mass phosphorus nesibabule ncibilika ngasinye elibukhali ngokucophelela. Uma inkampani isebenzisa izinto third-party, nomkhiqizi imibhalo edingekayo ngokuvumelana izinga. Namuhla, ezinye izinkampani ukukhiqiza imikhiqizo nge ebusweni yangaphakathi (isib TC-34R), esiza ukuvikela ipayipi kusukela ezonakalisayo bafake olwalwenza, ukugqwala yokubeka, ukwehlisa ematfuba ukukhathala ukwa, futhi ukulahlekelwa wokubacindezela ngesikhathi imishini. I enamathela lisetshenziswa ebusweni indlela ibe ngumsizi ivumela tube ukumelana amahora angaphezu kuka-500 at okushisa ngenhla 150C, ukuthola amandla umthelela angaphezulu kwangu-8 ku-20 J C et al.

Ukugubha amapayipi zaziwa ngokuthi imishini, okuvame iphula ngenxa ukugqoka ububanzi ukukhiya (yangaphandle, angu-60% kuzona zonke izimo). Lapho ingxenye esele okuvela kuyo le tube Site ukusetshenziswa. Muva nje, ukuxazulula le izindlela inkinga wayekwenza Carbide hardfacing sivala. Lokhu ugwema imifantu ukwakha izimo ephezulu voltage, nezinye izinto zokuxhashazwa kakhulu.
