Ipayipi lensimbi le-40Cr lenziwe ngokwezifiso ngumenzi
Ipayipi elingenamthungo lensimbi engagqwali (GB / T14975-2002) liyipayipi elishisayo eligoqekayo (elinwetshiwe, elinwetshiwe) elidonswayo (eligoqiwe) elingenamthungo elenziwe ngensimbi engagqwali lamapayipi amelana nokugqwala, izingxenye zesakhiwo kanye nezingxenye zamakhemikhali, i-petroleum, ukukhanya. izimboni zendwangu, ezokwelashwa, zokudla, zemishini nezinye.
Indlela yokubala yepayipi yensimbi yesakhiwo: (ububanzi bangaphandle - ukujiya kodonga) * ukujiya kodonga * 0.02466 = isisindo sepayipi lensimbi imitha ngayinye

Ngaphezu kwalokho, kukhona i-GB / t17396-2009 (ipayipi lensimbi elingenamthungo elishisayo le-hydraulic prop)
I-Gb3093-1986 (ipayipi lensimbi engenamthungo ephezulu yenjini ye-diesel)
I-GB / t3639-1983 (amashubhu ensimbi angenamthungo adonsayo noma abandayo agoqeka ngokunemba)

I-API Spec 5ct-1999 (Isicaciso se-casing kanye neshubhu), njll. Ipayipi lesakhiwo elibandayo (eligoqiwe): ipayipi eliyindilinga alinalutho → ukushisisa → ukubhoboza → isihloko → i-annealing → pickling → ukugcoba uwoyela (i-copper plating) → umdwebo obandayo wokudlula okuningi (okubandayo ukugoqa) → ipayipi elingenalutho → ukwelashwa kokushisa → ukuqondisa → ukuhlolwa kwe-hydrostatic (ukutholwa kwamaphutha) → ukumaka → indawo yokugcina impahla.
Ukuginqika okushisayo (ipayipi lesakhiwo elikhishiwe): ipayipi eliyindilinga alinalutho → ukushisisa → ukubhoboza → ukugoqeka kwama-roll amathathu, ukugoqeka okuqhubekayo noma ukukhishwa → ukuhlubula amapayipi → ukusika (noma ukunciphisa) → ukupholisa → ipayipi elingenalutho → ukuqondisa → ukuhlolwa kwe-hydrostatic (noma ukutholwa kwamaphutha) → ukumaka → ukugcinwa kwempahla.
Ipayipi lesakhiwo elidonswa ngokubanda lisebenzisa ikhoyili yensimbi egoqwe ngokushisayo njengempahla eluhlaza futhi lenza ukugingqa okuqhubekayo okubandayo ngemva kokukha i-asidi ukuze kukhishwe isikali se-oxide. Umkhiqizo osuphelile ikhoyili eqinile egoqiwe. Ngenxa yokuqina komsebenzi obandayo okubangelwa ukuguquguquka okubandayo okuqhubekayo, amandla kanye nobulukhuni bekhoyili egoqiwe kuyakhula kanye nokuqina kanye ne-plasticity index. Ngakho-ke, ukusebenza kwesitembu kuzowohloka futhi kungasetshenziselwa izingxenye ezikhubazekile kuphela. Ikhoyili egoqwe kanzima ingasetshenziswa njengezinto ezingavuthiwe zesitshalo sokuhlanganisa i-hot-dip galvanizing, ngoba amayunithi okugalela amanzi ashisayo afakwe izintambo zokudonsa. Isisindo sekhoyili eqinile egoqiwe ngokuvamile si-6 ~ 13.5T, kanti ububanzi bangaphakathi bekhoyili yensimbi bungu-610mm.
Ngokuvamile, ukufakwa kwensimbi okuqhubekayo (iyunithi ye-CAPL) noma ukufakwa kwesithando somlilo kwensimbi kuzokwenziwa kumapuleti namakhoyili abandayo ukuze kuqedwe ukuqina komsebenzi obandayo kanye nengcindezi yokugingqika, ukuze kuhlangatshezwane nezinkomba zezakhiwo zikamshini ezicaciswe kumazinga ahambisanayo.
Ikhwalithi engaphezulu, ukubukeka nokunemba kobukhulu bepayipi lesakhiwo eligoqelwe ngokubanda lingcono kunalepayipi lesakhiwo eligoqelwe ngokushisayo, futhi ukujiya komkhiqizo walo kugoqelwe kahle kuze kube ngu-0.18mm, ngakho-ke ithandwa iningi labasebenzisi. Ukuthatha ikhoyili yensimbi egoqiwe ebandayo njengephayiphi lesakhiwo esiyisisekelo sokucutshungulwa okujulile kwemikhiqizo, isiphenduke umkhiqizo ophezulu we-value-added. Okufana ne-electro galvanizing, i-hot galvanizing, i-electro galvanizing engamelana nezigxivizo zeminwe, ikhoyili yensimbi ehlanganiswe ngombala, ipuleti lensimbi eliyinhlanganisela yokudlidliza, ipuleti lensimbi elakhiwe nge-PVC, njll., ukuze le mikhiqizo ibe nenhle, ukumelana nokugqwala okuphakeme nezinye ikhwalithi enhle kakhulu, esetshenziswa kabanzi. Ikhoyili yensimbi egoqiwe ebandayo kufanele iqedwe ngemva kokucwiliswa, okuhlanganisa ukusika ikhanda, ukusika umsila, ukusika unqenqema, ukulinganisa, ukulinganisa, ukuhlehlisa, noma ipuleti le-shear longitudinal. Imikhiqizo egoqwe ngamakhaza isetshenziswa kakhulu ekwakhiweni kwezimoto, izinto zikagesi zasendlini, ukushintshwa kwezinsimbi, ezokwakha, ifenisha yasehhovisi nezinye izimboni. Isisindo senqwaba yamapuleti ensimbi singamathani ama-3 ~ 5. Isisindo sekhoyili eyisicaba ngokuvamile singamathani angu-3 ~ 10 / ikhoyili. I-diameter yangaphakathi yekhoyili yensimbi ingu-610mm.
Ipayipi lesakhiwo eligoqelwe ngokushisayo lisebenzisa i-casting slab eqhubekayo noma i-blooming slab njengempahla eluhlaza, eshiselwa ngezitebhisi zokushisa futhi yehliswe ngamanzi anomfutho ophezulu ngaphambi kokungena emshinini wokugawula. Izinto ezimangelengele zingena emshinini wokuqedela ngemva kokusika ikhanda, umsila bese zingena emshinini wokuphothula ukuze zigingqike okulawulwa yikhompyutha. Ngemva kokugoqeka kokugcina, igoqwa ibe ikhoyili yezinwele eziqondile ngokusebenzisa ukupholisa i-laminar kanye nekhoyili. Ikhanda nomsila we-curl yezinwele eziqondile kuvame ukwakheka kolimi futhi umsila wenhlanzi umise, ngokunganembi kahle kokuqina nobubanzi, futhi kuvame ukuba neziphambeko ezifana nokuma kwegagasi, umphetho, ukuma kombhoshongo nokunye. Isisindo sekhoyili sisinda futhi ububanzi bangaphakathi bekhoyili yensimbi bungama-760mm (Ngokuvamile, imboni yamapayipi iyakuthanda ukuyisebenzisa.) Ngemva kokuba ikhoyili yezinwele eziqondile icutshungulwe ngokusikwa kwekhanda, ukusika umsila, ukusika emaphethelweni, ukuqondisa amaphasi amaningi, ukulevelisa kanye eminye imigqa yokuphothula, iyasikwa noma iphinde ihlanganiswe ukuze ibe ipuleti lensimbi eligoqiwe elishisayo, ikhoyili yensimbi eyisicaba, ibhande lokusika longitudinal neminye imikhiqizo. Ikhoyili yokuqedela egoqwe ngokushisa izoba ikhoyili yokukhetha egoqwe ngokushisayo uma isikali se-oxide sisuswa ngokukhetha futhi sigcotshwe ngamafutha. Umkhiqizo unomkhuba wokushintsha kancane ipayipi lesakhiwo eligoqekile, ngentengo emaphakathi, futhi lithandwa kakhulu iningi labasebenzisi.
