Ipayipi elishiselwe i-Spiral (ipayipi le-SSAW)iwuhlobo lwepayipi lensimbi elivunguzayo elenziwe nge-strip steel coil njengento eluhlaza, elishiselwa inqubo yokushisela ye-arc enezintambo ezimbili ezizenzakalelayo enezinhlangothi ezimbili futhi ikhishwe ekamelweni lokushisa.Ubunjiniyela bokuhlinzeka ngamanzi, imboni ye-petrochemical, imboni yamakhemikhali, imboni yamandla kagesi, ukuchelela ngenkasa kwezolimo kanye nokwakhiwa kwamadolobha kuyizinkambu lapho ukuvunguza.amapayipi ashiselwezisetshenziswa kakhulukazi.

Izici eziyinhloko zenqubo ye-spiral welded pipe:

1. Phakathi nenqubo yokubumba, ukucindezeleka okusalayo kuncane futhi akukho ukuklwebheka ebusweni.Ipayipi elishiselwe elivunguzayo elicubunguliwe linezinzuzo ezingenakuqhathaniswa kusayizi nobubanzi bokucaciswa kobubanzi nokuqina kodonga, futhi lingahlangabezana nezidingo ezengeziwe zabasebenzisi zokucaciswa kwepayipi lensimbi ezungezayo.
2. Yamukela ubuchwepheshe bokushisela be-arc obunezinhlangothi ezimbili obuthuthukisiwe ukuze ubhekane nokukhubazeka okuthile, futhi kulula ukulawula ikhwalithi yokushisela.
3. Yenza ukuhlolwa kwekhwalithi engu-100% epayipini lensimbi, ukuze uqinisekise ikhwalithi yomkhiqizo.

4. Zonke izinto zokusebenza kuwo wonke umugqa wokukhiqiza zinomsebenzi wokuxhumana nohlelo lokutholwa kwedatha yekhompiyutha ukuze kuqashelwe ukudluliswa kwedatha yesikhathi sangempela, futhi imingcele yezobuchwepheshe enqubweni yokukhiqiza ilawulwa yigumbi lokulawula.

Ngenqubo yokushisa, imishini yokushisa yokushisa ukushisa kanye nendawo yokushisa kufanele kukhethwe.Okwenzekayo noma okulula ukwenzeka lapha ukuthi ubuso bengxenye buzothinteka yi-oxidizing heat medium, futhi izinga lokushisa lokushisa lidlula izidingo zenqubo.Uma izinhlamvu ze-austenite zikhulu kakhulu, ngisho nemingcele yokusanhlamvu izoncibilika, okuzothinta kakhulu ukubukeka kanye nekhwalithi yangaphakathi yezingxenye.Ngakho-ke, ohlelweni lwangempela, izinyathelo ezinokwenzeka kufanele zithathwe ukuze kuhlaziywe amaphutha anjalo.

Izingxenye ezingalungile ezikhiqizwa ngesikhathi sokushisa ziyacinywa ukuze zithole isakhiwo se-martensite esicinyiwe esinobunzima obuphezulu noma isakhiwo esiphansi se-bainite esinobunzima obuncane obuphansi, kodwa isakhiwo asizinzile futhi sihlakazekile.Lapho isetshenziswa ekukhiqizeni, iyathukuthela ukuze ithole isakhiwo esifunwayo kanye nezakhiwo.Ngakho-ke, amapharamitha wenqubo yokushisa azoba nomthelela obalulekile kwikhwalithi yokwelashwa kokushisa kwezingxenye, njengokuqina, ukuqina kwe-temering, imifantu epholile kanye nezinye iziphambeko, futhi izinyathelo kufanele zithathwe ukugwema lezi ziphambeko ngesikhathi sokushisa.

Inqubo efanele yokwelapha ukushisa isisekelo nesisekelo sokuqinisekisa ikhwalithi yokwelashwa kokushisa efanelekayo yezingxenye.Uma izinkinga zekhwalithi ezingenhla sezitholakele, zingaxazululwa ezicini zabantu, imishini, izinto zokwakha, izindlela, izixhumanisi, ukuhlolwa, njll. Ngokuhlaziya nokwahlulela, imbangela eyinhloko yesici ingatholakala.

Amakhono okugcina amapayipi ashiselwe okuvunguzayo:

1. Indawo yokugcina noma ishede yemikhiqizo yamapayipi ensimbi ezungezayo kufanele ibe endaweni ehlanzekile nengenamanzi.Ukhula kanye nawo wonke ama-sundries kufanele ahlanzwe.Izinsimbi zensimbi kufanele zigcinwe zihlanzekile futhi zikude nezimboni nezimayini ezikhiqiza amagesi ayingozi noma uthuli.
2. Izinto ezigqwala insimbi njenge-asidi, i-alkali, usawoti, nosimende akufanele zipakishwe endaweni yokugcina impahla, futhi insimbi yezinhlobo ezihlukene izopakishwa ngokuhlukana.Vimbela ukudideka nokugqwala kokuxhumana.
3. Insimbi yesigaba esincane nesiphakathi nendawo, intambo yocingo, insimbi, ipayipi lensimbi enobubanzi obuphakathi, intambo yensimbi nentambo yocingo, njll. Ngemva kokubeka nokufaka i-cushioning, ingagcinwa eshedeni elinomoya ohlanzekile.

4. Insimbi encane, ipuleti lensimbi elincanyana, umucu wensimbi, ishidi lensimbi ye-silicon noma ipayipi lensimbi elivunguzayo elinezindonga ezincane lingagcinwa.Izinhlobonhlobo zenani eliphezulu, insimbi egqwalayo egoqekayo nedonswa ngokubanda nemikhiqizo yensimbi ingagcinwa.
