Pipe yesimbi ine welds inogoverwa mumhepo inotenderera kune axis yemuviri wepombi. Inonyanya kushandiswa semapaipi ekufambisa, mapaipi epombi, uye mamwe mapaipi emuumbirwo. Product nokurondedzerwa: kunze dhayamita 300 ~ 3660mm, rusvingo ukobvu 3.2 ~ 25.4mm.
Hunhu hwe spiral welded pombi kugadzirwa ndeiyi:
(1) Mapaipi ane madhayamita akasiyana-siyana ekunze anogona kugadzirwa kubva kumatsetse ehupamhi hwakafanana;
(2) Iyo pombi ine kutwasuka kwakanaka uye mipimo chaiyo. Iyo yemukati uye yekunze spiral welds inowedzera kuomarara kwepombi muviri, saka hapana chikonzero chekuyera uye kutwasanudza maitiro mushure mekugadzira;
(3) Zviri nyore kuona mechanization, otomatiki, uye inoenderera kugadzirwa;
(4) Zvichienzaniswa nemimwe midziyo yechiyero chakafanana, ine zvimiro zvidiki, kushomeka kwekugara kwevhu nekudyara, uye inokurumidza kuvaka;
(5) Kana ichienzaniswa neakatwasuka seam welded mapaipi ehukuru hwakafanana, weld seam payuniti urefu hwepombi yakareba, saka kubereka kwakaderera.

Iyo yekugadzira maitiro ekuyerera kwe spiral welded pombi:
Izvo zvigadzirwa zve spiral welded pombi zvinosanganisira mitsetse uye mahwendefa. Ndiro inoshandiswa kana ukobvu huri pamusoro pe19mm. Paunenge uchishandisa mitsetse, kuve nechokwadi chekuenderera mberi kwekupihwa kwezvinhu panguva yekubatira butt kwemberi nekumashure macoil, looper mudziyo unogona kushandiswa, kana nhunzi welding trolley inogona kushandiswa kubatanidza butt welding. Iyo yese gadziriro yekugadzira zvinhu kubva pakusunungura kusvika pabutt welding inogona kuitwa pamwe nenjanji pane inobhururuka welding trolley. Yakapedzwa panguva yekufamba. Kana muswe wesimbi yekumberi ukabatwa nechekumashure chemushini wewelding, trolley inodhonzwa kumberi nekumhanya kwakafanana neyekugadzira uye pre-welding muchina. Mushure mekunge butt welding yapera, simbi yekumashure inosunungurwa uye trolley inodzoka pachayo. kunzvimbo yepakutanga. Paunenge uchishandisa mahwendefa, mahwendefa esimbi ega anofanirwa kuve akaiswa butt-weld kuita mitsetse iri kunze kwetambo yekushanda, uye yozotumirwa kune yekushanda process line kuti ive butt-welded uye yakabatana neinobhururuka welding mota. Butt welding inoitwa pachishandiswa automatic submerged arc welding, iyo inoitwa mukati mepombi. Nzvimbo dzisina kupindwa dzakaumbwa uye dzakatangira-welded, uye dzinogadziriswa pamusoro pekunze kwepombi, uye ipapo spiral welds inosungirirwa mukati uye kunze. Mutsetse usati wapinda mumuchina wekugadzira, mupendero wemutsetse unofanirwa kuve wakakotama kune imwe curvature zvichienderana nedhayamita yepombi, ukobvu hwemadziro, uye kona yekugadzira, kuitira kuti deformation curvature yemupendero uye yepakati chikamu mushure mekugadzira. zvinoenderana nekudzivirira "bamboo" kukanganisa kwenzvimbo dzakabudikira. Mushure mekutanga kupeta, inopinda mumhepo yekare yekuumba (ona spiral forming) uye pre-welding. Kuti uvandudze kubereka, mutsara wekugadzira uye pre-welding unowanzoshandiswa kuenzanisa mitsara yakawanda yemukati nekunze. Izvi hazvigone chete kuvandudza kunaka kwewelds asiwo zvakanyanya kuwedzera kugadzirwa. Pre-welding inowanzo shandisa yakadzivirirwa gasi arc welding kana yakakwira-frequency resistance welding ine kukurumidza kumhanyisa kumhanya, uye yakazara-kureba welding. Iyi welding inoshandisa multi-pole otomatiki yakanyura arc welding.

Iyo huru yekusimudzira nzira ye spiral welded pombi kugadzirwa imhaka yekuti kutakura kudzvanywa kwepombi kuri kuwedzera zuva nezuva, mamiriro ekushandisa ari kuwedzera kuomarara, uye hupenyu hwesevhisi hwemapombi hunofanirwa kuwedzerwa zvakanyanya sezvinobvira, saka nzira huru dzekusimudzira spiral welded pipes ndeaya:
(1) Gadzira mapaipi akakura-dhayamita akakobvu-ane madziro kuti uvandudze kusamira;
(2) Gadzirai uye gadzirai mapaipi matsva esimbi, akadai semapombi ane maviri-layer spiral welded, anonamirwa kuita mapaipi ane mativi maviri ane simbi yeshinda hafu yeukobvu hwemadziro epombi. Haasi simba radzo chete rakakwirira kudarika mapaipi e-single-layer ehupamhi hwakafanana, asi haazokonzeri kukanganisa brittle;
(3) Gadzira mhando nyowani dzesimbi, kuvandudza tekinoroji yemaitiro ekunyungudutsa, uye kutora zvakanyanya kudzorwa kutenderedzwa uye post-kukungurusa marara ekupisa kupisa maitiro kuti arambe achivandudza simba, kuoma, uye welding mashandiro emuviri wepombi;
(4) Gadzira zvakasimba pombi dzakavharwa. Semuenzaniso, kuvhara madziro emukati wepombi ne-anti-corrosion layer hakungowedzere hupenyu hwesevhisi, asi zvakare kuvandudza kutsetseka kwemadziro emukati, kuderedza kukwesha kwemvura, kuderedza wax uye tsvina kuunganidzwa, kuderedza huwandu hwepombi. nguva dzekuchenesa, uye kuderedza kuchengetedza.
