Ipayipi elishiselwe elivunguzayo (isasa): Yenziwa ngokugingqa insimbi ene-carbon structural steel noma i-alloy structural steel strip ibe ishubhu elingenalutho ngokwe-engeli ethile ye-helical (ebizwa ngokuthi i-engeli yokubumba), bese i-welding umphetho wepayipi. Ingenziwa nge-strip steel emincane ikhiqiza amapayipi amakhulu ensimbi ububanzi. Ukucaciswa kwayo kuvezwa ububanzi obungaphandle * ukujiya kodonga. Iipayipi elishiselwekufanele kuqinisekiswe ukuthi ukuhlolwa kwe-hydraulic, amandla aqinile we-weld kanye nokusebenza kokugoba okubandayo kufanele kuhlangabezane nemithethonqubo.

Izinzuzo ze-spiral welded pipe:

(1) Amapayipi ensimbi anobubanzi obuhlukene angakhiqizwa kusetshenziswa insimbi yomugqa enobubanzi obufanayo, ikakhulukazi amapayipi ensimbi anobubanzi obukhulu angakhiqizwa ngensimbi emincane.
(2) Ngaphansi kwezimo ezifanayo zokucindezela, ingcindezi yomthungo oshiselwe okuvunguzayo incane kunaleyo yomthungo oqondile, okungama-75% kuya ku-90% wepayipi elishiselwe ngomthungo oqondile, ngakho lingakwazi ukumelana nokucindezela okukhulu. Uma kuqhathaniswa namapayipi ashiselwe ngomthungo oqondile anobubanzi obufanayo bangaphandle, ukushuba kodonga kungancishiswa ngo-10% kuya ku-25% ngaphansi kwengcindezi efanayo.
(3) Ubukhulu, ukubekezelelana kobubanzi okuvamile akudluli u-0.12%, ukuchezuka kungaphansi kuka-1/2000, kanti i-ellipticity ingaphansi kuka-1%. Ngokuvamile, izinqubo zokulinganisa nokuqondisa zingashiywa.
(4) Ingakhiqizwa ngokuqhubekayo. Ngombono, ingakhiqiza amapayipi ensimbi amade ngokungenamkhawulo. Ukulahlekelwa ikhanda nomsila wokusika kuncane, futhi izinga lokusebenzisa insimbi lingakhuphuka ngo-6% kuya ku-8%.
(5) Uma kuqhathaniswa nepayipi elishiselwe longitudinal, liyaguquguquka ekusebenzeni futhi lilungele ukushintsha izinhlobo nokulungiswa.
(6) Okokusebenza kunesisindo esincane futhi kuncane ekutshalweni kwezimali kokuqala. Ingenziwa ibe iyunithi engomahambanendlwana yohlobo lwe-trailer ukukhiqiza amapayipi ashiselwe ngqo endaweni yokwakha lapho amapayipi abekwe khona.
(7) Kulula ukubona imishini kanye ne-automation.

Ububi bepayipi elishiselwe ku-spiral yilokhu:ngoba insimbi ye-strip ehlanganisiwe isetshenziswa njengezinto ezingavuthiwe, kukhona ukugoba okuthile, futhi indawo yokushisela isendaweni enqenqemeni yensimbi ye-strip enokuqina, ngakho-ke akulula ukuvumelanisa ithoshi lokushisela, elithinta ukushisela. izinga. Ukuze wenze lokhu, imishini yokulandelela i-seam eyinkimbinkimbi kanye nekhwalithi yokuhlola imisiwe.

Indlela yokuthuthukiswa kwepayipi elishiselwe elivunguzayo:

Ngenxa yengcindezi eyandayo yokuthwala ipayipi, izimo zesevisi eziba nzima, kanye nesidingo sokwelula impilo yesevisi yepayipi ngangokunokwenzeka, ukuthuthukiswa kokuqondisa okuyinhloko kwepayipi elishiselwe okuvunguzayo yileli:
(1) Khiqiza amapayipi anezindonga ezinkulu ezinobubanzi obukhulu ukuze kuthuthukiswe ukumelana nomfutho;
(2) Dizayina futhi ukhiqize amapayipi ensimbi anezakhiwo ezintsha, njengamapayipi ashiselwe anongqimba oluphindwe kabili, okungukuthi, amapayipi anengqimba ephindwe kabili ashiselwe anensimbi ewugqinsi uhhafu wobukhulu bodonga lwamapayipi, anamandla angaphezulu nje kolwendlalelo olulodwa. amapayipi of the ukushuba efanayo, kodwa futhi akubonakali ukwehluleka brittle;
(3) Ukuthuthukisa izinhlobo ezintsha zensimbi, uthuthukise izinga lobuchwepheshe bokuncibilika, futhi usebenzise kabanzi ubuchwepheshe bokwelapha ukushisa okuginqikayo kanye nokuginqika kwemfucuza ukuze kuthuthukiswe ngokuqhubekayo amandla, ukuqina nokusebenza kokushisela komzimba wepayipi;

4 ukunqwabelana kanye nokungcola, ukunciphisa inani lamapayipi okuhlanza, nokunciphisa izindleko zokulungisa.

PS:Amapayipi ensimbi ashiselwebabe nezindleko eziphansi kanye nokusebenza kahle kokukhiqiza okuphezulu kuneamashubhu angenamthungo. Umthungo oqondile wepayipi elishiselwe linenqubo elula yokukhiqiza, ukusebenza kahle kokukhiqiza okuphezulu, izindleko eziphansi kanye nentuthuko esheshayo. Amandla epayipi elishiselwe okuvunguzayo ngokuvamile aphakeme kunalawo epayipi elishiselwe ngokuqondile.
