Joini yepombi yekuboorera chikamu chepombi yekuboorera, yakakamurwa kuita majoini evarume neevakadzi, akabatana kumativi ese emuviri wepombi yekuboorera. Chinobatanidza chinopiwa shinda yekuboorera yeshinda (shinda yakakora yescrew) yekubatanidza pombi yega yega yekuboorera. Mukuita kwekuboorera, joini inowanzo patsanurwa, uye pamusoro pejoini panosangana simba guru rekuruma, saka ukobvu hwemadziro ejoini yepombi yekuboorera hwakakura, dhayamita yekunze yejoini yakakura kupfuura dhayamita yekunze yemuviri wepombi, uye simbi yesimbi ine simba rakawanda inoshandiswa. Majoini epombi yekuboorera epamba anowanzo gadzirwa nesimbi yesimbi ye35CrMo.
Kubatana kweshinda yekurukira kunofanirwa kugutsikana nemamiriro matatu, kureva kuti, saizi yakaenzana, rudzi rweshinda yekurukira yakafanana, uye shinda yekurukira yechirume neyechikadzi inoenderana. Saizi dzekubatana kwepipi dzakasiyana dzekurukira dzakasiyana. Rudzi rweshinda yepipi yekurukira yehukuru hwakafananawo yakasiyana. Rudzi rwekubatana runoshandiswa nemugadziri wega wega wepipi yekurukira rwakaomawo kuti ruve rwakafanana. Nokudaro, kuitira kuti zvive nyore kusiyanisa pakati pemajoini epipi yekurukira nekushandiswa kweinjiniya, API yakaita zvinhu zvakafanana parudzi rwemajoini epipi yekurukira, ichigadzira majoini epipi yekurukira yeAPI anowanzo shandiswa muindasitiri yepeturu.
Mapombi eAPI anowanikwa mumatanho ekare neetsva. Nzvimbo yekare yeAPI drill pipe inokurudzirwa kushandiswa kwekutanga kwepombi ye drill fine, iyo yakakamurwa kuita mhando nhatu: internal flat (IF), perforated (FH) uye regular (REG).
Chisungo chemukati chakati sandara chinoshandiswa zvakanyanya pakukora kwepaipi yekuboorera, iyo inoratidzwa nedhayamita yemukati yepombi yekuboorera uye dhayamita yemukati yejoinhi pakukora kwepombi, uye kuramba kwemvura yekuboorera kudiki, izvo zvinobatsira kuvandudza simba remvura rechikamu chekuboorera, asi dhayamita yekunze yejoinhi yakakura uye iri nyore kupfeka.
Jointi yakaboorwa yakakodzera kukobvu kwemukati kwepombi yekuboorera, iyo inoratidzwa nedhayamita mbiri dzemukati dzepombi yekuboorera, uye dhayamita yemukati yejointi yakaenzana nedhayamita yemukati yekukobvu kwemuviri wepombi, asi iri pasi pedhayamita yemukati yechikamu chemuviri wepombi. Kudzivirira kwemvura yekuboorera inoyerera nepajointi kwakakura kupfuura kwejointi yemukati yakatsetseka, asi dhayamita yayo yekunze idiki pane yejointi yemukati yakatsetseka.
Jointi yenguva dzose yakakodzera kukora kwemukati kwepombi yekuboorera. Dhayamita yemukati mejointi iyi idiki, iri pasi pedhayamita yemukati yekukora kwepombi yekuboorera. Nokudaro, kune dhayamita nhatu dzakasiyana dzebore dzepombi yekuboorera dzakabatana nejointi dzakajairika. Mvura yekuboorera inoyerera nepajointi iyi ine simba guru, asi ine dhayamita diki yekunze uye simba guru. Jointi dzakajairwa dzinowanzo shandiswa papombi yekuboorera dhayamita diki uye pombi yekuboorera yekudzokera shure, pamwe chete nedrills, maturusi ekuredza, nezvimwewo. Mhando nhatu dzejointi dzese dzinoshandisa shinda dzechimiro che "V", asi mhando yeshinda yescrew (inoratidzwa nehupamhi hwekucheka kwepamusoro), daro reshinda yescrew, taper uye saizi zvakasiyana zvikuru.
Kuzivikanwa kwemajoini
1.hole FH, XH, hazviwanzo kuwanikwa muchitoro chezvishandiso, hazviwanzo shandiswa.
2. IF inoshandiswa zvakanyanya uye REG yakajairika, musiyano ndewekuti:
KANA mabhatani mana pa inchi imwe neimwe, shinda yekuruu inenge yakakora, uye taper idiki, mabhatani eREG mashanu pa inchi imwe neimwe, shinda yekuruu idiki, uye taper yakakura. Saizi yeshinda yekuruu yeIF inotangira pa2-3/8 "kusvika 4-1/2", uye ayo makuru kupfuura 4-1/2 "haana IF, kazhinji REG, apo 7-5/8" uye pamusoro haana REG.
3. Nzira yekutaura yakajairika:
Inomiririrwa nenhamba nhatu, dzakadai se310,410,411, nezvimwewo.
Nhamba yekutanga inoratidza saizi (2 ~ 7) kazhinji: 2-2 -, 3-3-7/8 ", 1/2 ", 4-4-1/2 ", 5 1/2 "- 5 -, 6-6-5/8", Chikunguru 7-5/8 ";
Nhamba yechipiri inoratidza rudzi rweshinda ye screw (pane 1, 2, 3), 1-- IF; 2---FH; 3-- REG;
Nhamba yechitatu inomiririra murume nemukadzi (inomiririrwa na 0 na 1)
0--Bhokisi (rechikadzi); 1--Pin (rechirume);
4. Dzimwe mhando dzeshinda dzemapipi ekuboorera dzinozivikanwa ndedzeBTC, MT, AMT, HT55 nezvimwewo.
5. Pamusoro pezvo, mhando yeshinda yescrew yakajairika yemota 7-5/8 "REG, 6-5/8" REG, 4-1/2 "REG, inewo 4-1/2" IF. Mhando yeshinda yescrew yakajairika yepipe scraper uye hydraulic cutter ndiyo REG.
