Spiral welded pipe (saw): Inogadzirwa nekukungurutsa yakaderera-kabhoni kabhoni structural simbi kana yakaderera alloy structural simbi tambo muchubhu isina chinhu maererano neimwe helical angle (inonzi forming angle), uyezve welding pombi musono. Inogona kugadzirwa neyakamanikana strip simbi inoburitsa hombe dhayamita simbi mapaipi. Zvinotsanangurwa zvaro zvinoratidzwa nekunze dhayamita * madziro ukobvu. Thewelded pombiinofanirwa kuve nechokwadi chekuti hydraulic test, simba rekusimba re weld uye kutonhora kwekukotama kuita kunofanirwa kusangana nemirairo.

Zvakanakira zve spiral welded pipe:

(1) Mapombi esimbi emadhayamita akasiyana anogona kugadzirwa nekushandisa simbi simbi yehupamhi hwakafanana, kunyanya mapaipi esimbi ane dhayamita yakakura anogona kugadzirwa nesimbi yakamanikana.
(2) Pasi pemamiriro akafanana ekumanikidza, kushushikana kwe spiral welded seam idiki pane yeyakatwasuka, inova 75% kusvika 90% yeiyo straight seam welded pombi, saka inokwanisa kutsungirira kumanikidza kukuru. Kuenzaniswa neakatwasuka seam welded mapaipi ane dhayamita yekunze yakafanana, ukobvu hwemadziro hunogona kudzikiswa ne10% kusvika 25% pasi pekumanikidza kwakafanana.
(3) Zviyero, kushivirira kwakawanda hakupfuuri 0.12%, kutsauka kuri pasi pe1/2000, uye ellipticity iri pasi pe1%. Kazhinji, kuyera uye kutwasanudza maitiro anogona kusiiwa.
(4) Inogona kugadzirwa nguva dzose. Muchidzidzo, inogona kugadzira zvisingaperi mapaipi esimbi akareba. Kurasikirwa kwekucheka musoro nemuswe kudiki, uye chiyero chekushandiswa kwesimbi chinogona kuwedzerwa ne6% kusvika 8%.
(5) Kuenzaniswa nepitudinal welded pombi, inochinjika mukushanda uye iri nyore mukuchinja mhando uye kugadzirisa.
(6) Midziyo yakareruka muhuremu uye yakaderera mukutanga mari. Inogona kugadzirwa kuita trailer-mhando yenharembozha kuti igadzire mapombi akaiswa akananga panzvimbo yekuvaka panoiswa mapaipi.
(7) Zviri nyore kuona mechanization uye otomatiki.

Izvo zvisingabatsiri zve spiral welded pipe ndezvi:nekuti iyo coiled strip simbi inoshandiswa seyakagadzirwa, pane imwe crescent bend, uye welding point iri pamucheto wesimbi ye strip ine elasticity, saka hazvisi nyore kurongedza torch yewelding, iyo inokanganisa welding. quality. Kuti uite izvi, yakaoma seam yekutevera uye yemhando yekuongorora michina inomiswa.

Iyo nzira yekusimudzira ye spiral welded pipe:

Nekuda kwekuwedzera kuri kuita kudzvanywa kwepombi, kuwedzera kuomarara kwemamiriro ebasa, uye kukosha kwekurebesa hupenyu hwesevhisi yepombi zvakanyanya sezvinobvira, nzira huru yekusimudzira yespiral welded pombi ndeye:
(1) Gadzira mapaipi akakura-dhayamita akakobvu-ane madziro kuti uvandudze kusamira;
(2) Dhizaina uye gadzira pombi dzesimbi dzine zvimiro zvitsva, senge kaviri-layer spiral welded pombi, kureva, akaiswa kaviri-layer pombi ane strip simbi hafu yeukobvu hwemadziro epombi, ayo asina simba rakakwirira kupfuura rimwe-layer. mapaipi ehukobvu hwakafanana, asi zvakare haaratidzi kutadza brittle;
(3) Gadzira mhando nyowani dzesimbi, kuvandudza nhanho yekunyungudutsa tekinoroji, uye kutora zvakanyanya kudzorwa kutenderedzwa uye post-kukungurutsa tsvina kupisa kupisa tekinoroji kuti urambe uchivandudza simba, kuoma uye welding kuita kwepombi muviri;

(4) Simbisa mapombi akavharwa zvine simba, sekupfekedza madziro emukati mepombi ne-anti-corrosion layer, iyo isingangorebese hupenyu hwesevhisi, asiwo inovandudza kutsvedzerera kwemadziro emukati, kuderedza kukwesha kwemvura, kuderedza wakisi. kuunganidza uye tsvina, kuderedza nhamba yekuchenesa pombi, uye kuderedza mari yekugadzirisa.

PS:Welded simbi pombivane mutengo wakaderera uye nepamusoro pekugadzira kugona kupfuuramachubhu asina musono. Yakatwasuka musono welded pombi ine yakapusa kugadzirwa maitiro, yakakwirira kugadzirwa kunyatsoita, yakaderera mutengo uye nekukurumidza kusimudzira. Kusimba kwe spiral welded pombi kazhinji kwakakwira kupfuura iyo yepiipi yakatwasuka yakasungwa.
