Kupititsa patsogolo zomangamanga za zimbudzi pogwiritsa ntchito mapaipi ozungulira a Arc (SSAW)

Kukulitsa Zomangamanga za Madzi Otayira Pogwiritsa Ntchito Mapaipi Ozungulira Ozungulira (SSAW) Chithunzi Chowonetsedwa

Kufotokozera Kwachidule:

Gawo ili la European Standard limafotokoza zaukadaulo woperekera zinthu za kapangidwe kozizira, kopanda kanthu, kozungulira, kozungulira, kapena kozungulira, ndipo limagwira ntchito ku zigawo zopanda kanthu zopangidwa ndi zozizira popanda kutentha.

Cangzhou Spiral Steel Pipes Group Co., Ltd imapereka mapaipi achitsulo ozungulira okhala ndi dzenje lopanda kanthu.

Dongosolo logwira ntchito bwino la zimbudzi ndilofunika kwambiri pakukula ndi chitukuko cha mzinda uliwonse. Pakumanga ndi kusamalirachimbudzimzeres, kusankha mapaipi oyenera ndi njira zoyikira ndikofunikira kwambiri. Mapaipi a Spiral submerged arc (SSAW) akhala njira yodalirika komanso yotsika mtengo yogwiritsira ntchito zomangamanga za zimbudzi. Cholinga cha blog iyi ndikuwunikira zabwino ndi momwe mapaipi a spiral submerged arc welded amagwiritsidwira ntchito popititsa patsogolo machitidwe a zimbudzi.

Chidule cha chitoliro chozungulira cholumikizidwa ndi arc:

Chitoliro chozungulira cha arc chozungulira, yomwe imadziwika kuti chitoliro chozungulira chozungulira chozungulira, imapangidwa pozungulira chitsulo chozungulira chotentha kukhala mawonekedwe ozungulira ndikuchilumikiza pamodzi ndi msoko wozungulira pogwiritsa ntchito njira yozungulira yozungulira. Mapaipi awa amapereka kulimba kwambiri, mphamvu komanso kukana dzimbiri, zomwe zimapangitsa kuti akhale abwino kwambiri pamapulojekiti ofunikira monga zimbudzi.

Ubwino wa chitoliro cha SSAW pakugwiritsa ntchito madzi otayira:

1. Kulimba: Mapaipi ozungulira ozungulira opangidwa ndi arc welded amapangidwa ndi chitsulo chapamwamba kwambiri ndipo amakhala olimba kwambiri. Ali ndi mphamvu zopirira katundu wolemera komanso mikhalidwe yovuta kwambiri pansi pa nthaka, zomwe zimapangitsa kuti mapaipi a zimbudzi azikhala nthawi yayitali.

2. Kukana dzimbiri: Njira yothira ma galvanizing yotenthedwa ndi kutentha imawonjezera chitetezo china ku chitoliro cholumikizidwa ndi arc, zomwe zimapangitsa kuti chikhale cholimba kwambiri. Izi ndizofunikira kwambiri pamakina a zimbudzi chifukwa nthawi zambiri amakumana ndi malo oopsa a mankhwala ndi zamoyo.

3. Kapangidwe kake kosataya madzi: Chitoliro cholumikizidwa ndi arc chozungulira chimapangidwa pogwiritsa ntchito njira yolumikizira mosalekeza kuti chitsimikizire kuti kapangidwe kake sikataya madzi. Mbali imeneyi imaletsa kulowa kapena kutuluka kwa madzi, motero kuchepetsa kuwonongeka kwa nthaka komanso kufunikira kokonza ndalama zambiri.

4. Kusinthasintha ndi kusinthasintha: Chitoliro cholumikizidwa ndi arc chozungulira chingapangidwe kuti chigwirizane ndi mainchesi osiyanasiyana, kutalika ndi malo otsetsereka, zomwe zimathandiza kuti pakhale kusinthasintha kwakukulu pakupanga njira zotsukira zinyalala. Zitha kusintha mosavuta malinga ndi kusintha kwa malo ndi komwe zikupita, kuonetsetsa kuti madzi otayira akuyenda bwino ngakhale m'malo ovuta otsukira zinyalala.

5. Kusunga Mtengo: Poyerekeza ndi zipangizo zachikhalidwe za mapaipi a zimbudzi monga konkire kapena dongo, mapaipi olumikizidwa ndi arc ozungulira amatha kusunga ndalama zambiri pakuyika ndi kukonza. Kupepuka kwawo kumachepetsa ndalama zotumizira ndipo ndi kosavuta kuyika, zomwe zimachepetsa zosowa za ogwira ntchito. Kuphatikiza apo, nthawi yayitali yogwirira ntchito komanso zosowa zochepa zosamalira zimathandiza kuti ndalama zigwire bwino ntchito kwa nthawi yayitali.

a. Njira yochotsera poizoni m'thupi imatchulidwa motere: FF: Chitsulo chophwanyika bwino chokhala ndi zinthu zomangira nayitrogeni mu kuchuluka kokwanira kumangirira nayitrogeni yomwe ilipo (monga osachepera 0,020% ya Al yonse kapena 0,015% ya Al yosungunuka). b. Mtengo wapamwamba kwambiri wa nayitrogeni sugwira ntchito ngati mankhwala akuwonetsa kuchuluka kwa Al komwe kuli 0,020% ndi chiŵerengero chochepa cha Al/N cha 2:1, kapena ngati pali zinthu zina zokwanira zomangira N. Zinthu zomangira N ziyenera kulembedwa mu Chikalata Chowunikira.

Kugwiritsa ntchito mapaipi a SSAW m'machitidwe otayira madzi:

1. Ma Network a Zimbudzi za Municipal: Mapaipi a SSAW amagwiritsidwa ntchito kwambiri popanga mizere yayikulu ya zimbudzi zomwe zimatumikira madera okhala anthu, amalonda ndi mafakitale. Mphamvu yawo komanso kukana dzimbiri zimapangitsa kuti akhale chisankho chabwino kwambiri chonyamulira madzi otayira mtunda wautali.

2. Kutulutsa madzi amvula:Mapaipi a SSAWamatha kuyendetsa bwino madzi amvula ndikuletsa kusefukira kwa madzi m'mizinda. Kulimba kwawo kumalola kusamutsa bwino madzi ambiri pakakhala madzi ambiri.

3. Malo Oyeretsera Zinyalala: Mapaipi ozungulira olumikizidwa ndi arc angagwiritsidwe ntchito popanga magawo osiyanasiyana a malo oyeretsera zinyalala, kuphatikizapo mapaipi osaphika a zinyalala, matanki opatsira mpweya ndi makina oyeretsera matope. Kukana kwawo mankhwala owononga komanso kuthekera kwawo kuthana ndi mavuto osiyanasiyana kumapangitsa kuti akhale ofunikira kwambiri m'malo ovuta otere.

Pomaliza:

Kusankha mapaipi oyenera ndikofunikira kwambiri pakupanga ndi kusamalira bwino njira yanu yotulutsira zinyalala. Mapaipi ozungulira ozungulira (SSAW) atsimikizira kuti ndi njira yotsika mtengo, yolimba komanso yosinthasintha yogwirira ntchito za zinyalala. Chifukwa cha kukana dzimbiri, kapangidwe kake kosataya madzi, komanso kusinthasintha m'malo osiyanasiyana, mapaipi a SSAW amatha kunyamula bwino madzi otayira, zomwe zimathandiza kuti mizinda ikule bwino. Kugwiritsa ntchito mapaipi ozungulira ozungulira ozungulira ozungulira m'mapulojekiti a zinyalala kungathandize kuti maukonde a zinyalala akwaniritse zosowa zomwe zikukulirakulira za chitukuko cha mizinda.
