6. Cold bend test Iyo galvanized simbi pombi ine dhayamita yezita isingapfuuri 50mm inofanira kuiswa kune inotonhora bend test.Kona yekubhenda i90 °, uye radius yekukotama ndiyo kasere yedhayamita yekunze.Iko hakuna yekuzadza panguva yekuyedzwa, uye weld yemuenzaniso inofanira kuiswa kunze kana kumusoro kwenzvimbo yekukotama.Mushure mekuedzwa, hapafanirwe kuve nekutsemuka uye peeling ye zinc layer pane sampuli.
7. Kuedzwa kwemvura yemvura Kuedzwa kwemvura kunofanira kuitwa mu clarinet.Eddy ikozvino kuona kukanganisa kunogona kushandiswawo panzvimbo yemvura yekumanikidza bvunzo.Chiyero chekuedza kana saizi yekuenzanisa sampuli yeeddy ikozvino yekuongorora ichasangana nezvinodiwa zveGB 3092. Iyo mechanical properties yesimbi indekisi yakakosha kuti ive nechokwadi chekupedzisira kushandiswa kwekuita (mechanical properties) yesimbi.
Shandong Jinbaicheng Metal Material Co., Ltd. iri muShandong, iyo yakakura pasi rose yakashongedzwa pombi yekugadzira pombi.Mushure memakore ekushanda nesimba, maitiro akasiyana-siyana ekusimudzira mari akaumbwa.Zvinoenderana nezvinodiwa zvekuvandudzwa kwemaindasitiri, isu tinopa kutamba kwakazara kune zvakanakira zvedu kuti tiwane chiyero, chimiro, uye mhando.Kuvandudzwa kwakakwana kwezvibatsiro.
Isu tinonyanya kutengesa mapaipi esimbi, hot-akakungurutswa simbi pombi, seamless pombi,.Mushure memakore akawanda ebudiriro, takagadzira kwenguva refu
Batira pamwe nevatengi vanobva kunyika dzinopfuura makumi manomwe pasirese, kusanganisira Canada, Australia, Singapore, Thailand, South Korea, Vietnam, Mexico, Chile, Peru, neNew Zealand.Kubuda kwegore negore i700,000 tons.
Galvanized simbi pombi yekubatanidza nzira: threaded, welded.
Roll groove connection
(1) Kutsemuka kwe roll groove weld
1. Svedzesa mukati memadziro welding mbabvu dzepressure groove chikamu chenozzle kuderedza kupikisa kwegoro rinokunguruka.
2, Gadzirisa axis yepombi yesimbi uye inotenderedza grooving midziyo, uye inoda kuti pombi yesimbi uye inomonereka girofu midziyo kuti ive nhanho.
3. Rongedza groove yekutsikirira kumhanya, uye groove yekugadzira nguva haigone kudarika chirevo, shandisa simba zvakaenzana uye zvishoma nezvishoma.
(2) Roll groove simbi pombi kuputsika
1. Svetesa mukati memadziro welding mbabvu dzepressure groove chikamu chemuromo wepombi kuti uderedze kupikisa kwegororo.
2, Gadzirisa axis yepombi yesimbi uye inotenderedza grooving midziyo, inoda kuti pombi yesimbi uye inotenderedza grooving midziyo kuti ive nhanho.
3. Rongedza kumhanya kwekudzvanya, kasi yekudzvanya haigone kudarika chirevo, shandisa simba zvakaenzana uye zvishoma nezvishoma.

1, Nzvimbo yepombi inopera kune chikamu che groove inofanira kuva yakatsetseka uye isina kuenzana uye mabhii.
2, Pakati pe groove inofanira kunge yakatarisana nemadziro epombi, hupamhi uye kudzika kwegorofu kunofanirwa kusangana nezvinodiwa, uye tarisa kana iyo clamp chikamu chemhando chakarurama.
3. Isa lubricant parubha sealing ring uye tarisa kana mhete yekuisa chisimbiso yerabha yakanganiswa.Mafuta haafanire kunge ari mafuta ekuzora.
Welded kubatana
1. Muromo wepombi wepombi yesimbi yakasvibiswa haisi mumutsara wakarurama uye kune dambudziko nemuromo we oblique wepombi yesimbi mushure mekuputika.Inokurudzirwa kugura musoro wepombi kwenguva pfupi isati yagadziriswa.
2, Mushure mekunge galvanized simbi pombi nozzles abatanidzwa, maviri nozzles haana kusimba akabatana, zvichikonzera kusaenzana ukobvu hwejoini yakasungwa;uye pombi ine elliptical nekuda kwezvikonzero zvayo kana mabhambu ekufambisa.Inokurudzirwa kugura musoro wepombi kwenguva pfupi.Process zvakare.
3. Pashure pokunge mhuno dzepombi dzesimbi dzaputirwa, matuzu anooneka pamuromo:
4. Nekuda kwezvikonzero zvehunyanzvi panguva yewelding.
5. Kune zinc nodules mumhino, izvo zvinogona kukonzera kunetsa kwewelding uye blisters.Kana zinc nodules dzakakura uye mapaipi akawandisa, zvinyoro zvinyoro zvezinc zvinofanira kubviswa.
Wire connection
1, Buckle ine Threaded: Iyo pombi hoop uye tambo yakarukwa haigone kubatwa zvachose, kusunungura, cheka chikamu chisina kujairika, uye woisa zvakare shinda.
2. Iyo tambo yepombi yesimbi uye pombi hoop thread haifanani uye haigoni kubatanidzwa.Iyo pombi hoop inofanira kutsiviwa kana kuti midziyo inofanira kugadziriswa uye kudzokorora tambo.
3. Kudhinda kusipo mushure mekunge pombi yesimbi yaiswa shinda: Edza kana ukobvu hwemadziro hwepombi yesimbi huchikwanisa kusangana nehupamhi hunodiwa hwepombi yakarukwa.
