Amapayipi ensimbi ngokuvamile ahlukaniswa abe amapayipi ensimbi angenamthungo kanye namapayipi ensimbi ashiselwe ngokuvumelana nendlela yokukhiqiza. Ngalesi sikhathi sethula ikakhulukazi amapayipi ensimbi ashiselwe, okungukuthi, amapayipi ensimbi athungelwe. Ukukhiqizwa kuwukugoba nokugoqa izikhala zamapayipi (amapuleti ensimbi nemicu yensimbi) zibe izingxenye ezidingekayo eziphambanayo ngezindlela ezihlukahlukene zokwakha. Uma kuqhathaniswa nepayipi lensimbi elingenamthungo elishiselwe ipayipi, inokunemba okuphezulu komkhiqizo, ukunemba okuphezulu kokuqina kodonga, imishini elula eyinhloko, indawo encane, izici zokusebenza okuqhubekayo nokukhiqizwa okuguquguqukayo ekukhiqizeni, ipayipi elishiselwe kufanele lihlukaniswe izigaba ezintathu: ukuvunguza okungaphansi kwamanzi. ipayipi elishiselwe i-arc, ipayipi elishiselwe umthungo oqondile elinezinhlangothi ezimbili ngaphansi kwamanzi, kanye nepayipi elishiselwe umthungo oqondile.

1. Ipayipi elishiselwe i-arc elingaphansi kwe-Spiral

Izinto zokusetshenziswa zepayipi lensimbi elivunguzayo (SSAW) i-strip coil, i-welding wire kanye ne-flux. Ngaphambi kokwakhiwa, i-strip ibhekana nokulingana, ukunqunyulwa konqenqemeni, ukuhleleka komphetho, ukuhlanzwa kwendawo nokudlulisa nokwelashwa kwangaphambili. Idivayisi yokulawula igebe le-welding isetshenziselwa ukuqinisekisa ukuthi igebe le-welding lihlangabezana nezidingo zokushisela Kudingeka ukulawula ngokuqinile ububanzi bepayipi, ukungahambi kahle kanye negebe le-weld. Ngemva kokusika epayipini elilodwa lensimbi, amapayipi amathathu okuqala eqoqo ngalinye kufanele ahlole uhlelo oluqinile lokuqala lokuhlola izici zemishini, ukwakheka kwamakhemikhali, isimo sokuhlangana kanye nobuso bendawo yokushisela. Ngemuva kokuhlolwa kwekhwalithi nokungonakalisi ukuqinisekisa ukuthi inqubo yokwenza ipayipi ifanelekile, ingafakwa ngokusemthethweni ekukhiqizeni.

2. Umthungo oqondile wepayipi elishiselwe i-arc

Ngokuvamile, umthungo oqondile wafaka ipayipi elishiselwe i-arc (LSAW) yenziwe nge-steel plate. Ngemva kwezinqubo ezahlukene zokwakha, ipayipi elishiselwe lakhiwa ukushiselwa kwe-arc engaphansi kwezinhlangothi ezimbili kanye nokwandiswa kwe-post-weld. Indlela yokwenza umthungo oqondile wepayipi elishiselwe i-arc i-UO (UOE). , RB (RBE), JCO (JCOE), njll.

Inqubo yokwakhiwa kwepayipi elishiselwe i-arc elingaphansi kwe-UOE:

Ikakhulukazi kunezinqubo ezintathu zokwenza ipayipi lensimbi le-UOE LSAW: ukugoba ipuleti lensimbi, ukwakheka kwe-U kanye nokwakheka kwe-O. Inqubo ngayinye isebenzisa umshini wokunyathelisa okhethekile ukuze iqedele ukugoba kwangaphambili, ukwenza u-U kanye no-O ukwakha unqenqema lwepuleti lensimbi ngokushintshana. Izinqubo ezintathu, ipuleti lensimbi liyakhubazeka libe yishubhu eliyindilinga, inqubo yokwenza ipayipi le-arc elishiselwe ngaphansi kwe-arc le-arc elishiselwe ngaphansi kwamanzi likhubazekile: ngemva kokunyathela okuningi emshinini wokwenza i-JC0, ingxenye yokuqala yepuleti lensimbi icindezelwa ibe yisimo esingu-J, bese enye uhhafu wepuleti lensimbi icindezelwa ekubunjweni komumo ka-J, kwakheka umumo ongu-C, ucindezelwe ukusuka maphakathi ukuze kwakhe ishubhu elivulekile elinomumo othi “O” elingenalutho.

Ukuqhathaniswa kwezindlela zokubumba ze-JCO ne-UO:

Ukwakhiwa kwe-JCO kuwukwakha ingcindezi eqhubekayo, eshintsha inqubo yokwakheka kwepayipi lensimbi lisuka ezinyathelweni ezimbili ze-UO kwakheka kwezinyathelo eziningi. Ngesikhathi sokwakhiwa, ipuleti lensimbi likhubazekile ngendlela efanayo, ukucindezeleka okusalayo kuncane, futhi indawo engaphezulu ayiklwebheki. Kukhona ukuguquguquka okukhulu kusayizi nobubanzi bokucaciswa kokuqina kodonga, okungakhiqiza yomibili imikhiqizo enevolumu enkulu kanye nemikhiqizo yeqoqwana elincane, hhayi nje amapayipi ensimbi anobubanzi obukhulu anokuqina okuphezulu anezindonga, kodwa futhi nobubanzi obuncane obukhulu- amapayipi ensimbi anezindonga, ikakhulukazi Ekukhiqizeni amapayipi anodonga oluwugqinsi lwekhwalithi ephezulu, ikakhulukazi ukukhiqizwa kwamapayipi anezindonga eziwugqinsi ezinobubanzi obuphakathi, kunezinzuzo ezingenakuqhathaniswa ngaphezu kwezinye izinqubo, futhi angahlangabezana nezidingo ezengeziwe zabasebenzisi zokucaciswa kwamapayipi ensimbi. . Ukwakhiwa kwe-UO kwamukela ukucindezela kuka-U no-O kwakha kabili, okubonakala ngokuthi Inomthamo omkhulu nokukhishwa okuphezulu. Ngokuvamile, okukhiphayo ngonyaka kungafinyelela kumathani angu-300,000 kuya ku-1,000,000, afanele ukukhiqizwa ngobuningi kokucaciswa okukodwa.

3. Straight umthungo high frequency ukumelana ashiselwe ipayipi

Ipayipi elishiselwe i-Sight seam high-frequency high-frequency welded (ERW) lakhiwa ngokusebenzisa umphumela wesikhumba kanye nomphumela oseduze we-high-frequency current ukushisa futhi kuncibilike unqenqema lweshubhu lungenalutho ngemva kokuba ikhoyili egoqelwe eshisayo kwakhiwa umshini wokwakha, bese i-pressure-welded ngaphansi kwesenzo se-roller extrusion.
