Spiral welded pipe (SSAW pipe)imhando ye spiral seam simbi pombi yakagadzirwa ne strip simbi coil seyakagadzirwa, iyo inosungirirwa ne otomatiki kaviri-waya mativi maviri akanyudzwa arc welding process uye extruded pakamuri tembiricha. Injiniya yekupa mvura, indasitiri yepetrochemical, indasitiri yemakemikari, indasitiri yemagetsi emagetsi, kudiridza kwekurima uye kuvaka kwemadhorobha ndiyo minda inotenderera.welded pombianonyanya kushandiswa.

Iyo huru maitiro maitiro e spiral welded pombi:

1. Munguva yekugadzira, kushushikana kwakasara kuduku uye hapana kukwenya pamusoro. Iyo yakagadziriswa spiral welded pombi ine mabhenefiti asingaenzaniswi muhukuru uye yakatarwa dhayamita uye ukobvu hwemadziro, uye inogona kusangana nezvimwe zvinodikanwa zvevashandisi kune spiral simbi pombi yakatarwa.
2. Adopt advanced-sided submerged arc welding tekinoroji kubata nekumwe kukanganisa, uye zviri nyore kudzora kunaka kwewelding.
3. Ita 100% yehutano yekuongorora pane pombi yesimbi, kuitira kuti uve nechokwadi chehutano hwechigadzirwa.

4. Midziyo yese mumutsara wese wekugadzira ine basa rekubatanidza nekombuta data acquisition system kuona chaiyo-nguva yekufambisa data, uye tekinoroji parameters mukugadzira maitiro inodzorwa nekamuri yekudzora.

Nokuda kwekupisa, kupisa kupisa midziyo yekupisa uye kupisa kwepakati kunofanira kusarudzwa. Chii chinoitika kana kuti chiri nyore kuitika pano ndechekuti pamusoro pechikamu chinozokanganiswa neoxidizing heat medium, uye tembiricha yekudziya inodarika zvinodiwa maitiro. Kana zviyo zve austenite zvakanyanyisa, kunyange miganhu yezviyo ichanyunguduka, iyo ichakanganisa zvakanyanya kuonekwa uye mukati mehutano hwezvikamu. Naizvozvo, mukuita chaiko, matanho anogoneka anofanira kutorwa kuti aongorore kukanganisa kwakadaro.

Zvikamu zvakakanganisika zvinogadzirwa panguva yekupisa zvinodzimwa kuti zviwane kudzima martensite chimiro nehupamhi hwepamusoro kana yakaderera bainite chimiro chine kuderera zvishoma, asi chimiro hachina kugadzikana uye brittle. Kana ichishandiswa mukugadzira, inodzikamiswa kuwana inodiwa chimiro uye zvivakwa. Naizvozvo, kudzikisira maparamendi anozove nekukanganisa kwakakosha pakupisa kwemhando yezvikamu, senge kuomarara, kudzikamisa brittleness, kupisa kutsemuka uye kumwe kukanganisa, uye matanho anofanirwa kutorwa kudzivirira kukanganisa uku panguva yekupisa.

Iyo chaiyo yekupisa kupisa maitiro ndiyo yekutanga uye hwaro hwekuona inokodzera kupisa kupisa kunaka kwezvikamu. Kana matambudziko ehutano ari pamusoro apa awanikwa, anogona kugadziriswa kubva kuzvinhu zvevanhu, michina, zvinhu, nzira, zvisungo, kuongorora, etc. Kuburikidza nekuongorora uye kutonga, chinokonzera kukanganisa chinogona kuwanikwa.

Unyanzvi hwekuchengeta spiral welded pipe:

1. Nzvimbo yekuchengetera kana dura rezvigadzirwa zve spiral simbi yepombi inofanira kunge iri munzvimbo yakachena uye yakanatswa. Masora nezvose zvakasiyana-siyana zvinofanira kucheneswa. Masimbi anofanirwa kugara akachena uye ari kure nemafekitari nemigodhi inoburitsa magasi anokuvadza kana huruva.
2. Zvishandiso zvinoparadza simbi zvakaita seasidhi, alkali, munyu, uye simende hazvifanirwe kurongedzerwa mudura, uye simbi dzemhando dzakasiyana dzichaiswa zvakasiyana. Kudzivirira kuvhiringidzika uye kubata ngura.
3. Chikamu chiduku uye chepakati-kati simbi, tambo yesimbi, simbi yesimbi, yepakati-diameter simbi pombi, tambo yesimbi uye tambo yetambo, nezvimwewo. Mushure mekuisa uye kusungirirwa, inogona kuchengetwa mushedhi ine mhepo yakanaka.

4. Simbi diki, simbi yakatetepa ndiro, simbi tambo, silicon simbi sheet kana nhete-yakavakirwa spiral simbi pombi inogona kuchengetwa. Mhando dzakasiyana-siyana dzemhando yepamusoro-soro, inoparadza inotonhora-yakakungurutswa uye inotonhora-inodhonzwa nesimbi uye zvigadzirwa zvesimbi zvinogona kuchengetwa.
