Kupititsa patsogolo Zomangamanga za Sewero Pogwiritsa Ntchito Mapaipi a Spiral Submerged Arc (SSAW)
Tsegulani:
Dongosolo lotayirira bwino lomwe ndi lofunikira kuti mzinda uliwonse ukule ndi chitukuko.Pomanga ndi kukonzangalandemzeres, kusankha mapaipi oyenerera ndi njira zoyikira ndizofunikira.Mipope ya Spiral submerged arc (SSAW) yakhala njira yodalirika komanso yotsika mtengo yopangira zida zachimbudzi.Cholinga cha buloguyi ndikuwunikira maubwino ndi kagwiritsidwe ntchito ka chitoliro cha spiral submerged arc welded popititsa patsogolo ngalande za ngalande.

Kufotokozera mwachidule kwa spiral submerged arc welded pipe:
Spiral arc chitoliro chomira pansi pamadzi, yomwe imadziwika kuti spiral submerged arc welded chitoliro, imapangidwa ndi kugudubuza zitsulo zotentha zozungulira ndikuzikulunga mozungulira msoko pogwiritsa ntchito njira yowotcherera ya arc yomira.Mapaipiwa amapereka kulimba kwakukulu, mphamvu ndi kukana kwa dzimbiri, zomwe zimawapangitsa kukhala abwino kwa ntchito zofunika kwambiri za zomangamanga monga zimbudzi.
Ubwino wa chitoliro cha SSAW muzosefera:
1. Kukhalitsa: Mapaipi opangidwa ndi Spiral submerged arc amapangidwa ndi chitsulo chapamwamba kwambiri ndipo amakhala olimba kwambiri.Amakhala ndi mphamvu zolimbana ndi katundu wolemetsa komanso mikhalidwe yapansi panthaka, kuonetsetsa moyo wautali wautumiki wamapaipi otayira.
2. Kukana kwa dzimbiri: Njira yothira galvanizing yotentha imawonjezera chitetezo ku chitoliro chomwe chili pansi pamadzi cha arc, ndikupangitsa kuti isachite dzimbiri.Katunduyu ndi wofunikira kwambiri pamakina otayira chifukwa nthawi zambiri amakumana ndi zida zankhondo komanso zachilengedwe.
3. Kapangidwe kamene kamasokonekera: Chitoliro chozungulira chozungulira cha arc chimapangidwa pogwiritsa ntchito njira yowotcherera mosalekeza kuti zitsimikizire kuti sizingadutse.Izi zimalepheretsa mwayi uliwonse wolowa kapena kutayikira, potero kuchepetsa kuthekera kwa kuipitsidwa kwa nthaka komanso kufunika kokonza zodula.
4. Kusinthasintha ndi kusinthasintha: Spiral submerged arc welded pipe imatha kupangidwa kuti igwirizane ndi ma diameter osiyanasiyana, utali ndi malo otsetsereka, zomwe zimalola kusinthasintha kwakukulu mu kapangidwe kake.Amatha kusinthasintha mosavuta ndi kusintha kwa mtunda ndi komwe akupita, kuonetsetsa kuti madzi otayira akuyenda bwino ngakhale m'mabwalo ovuta.
5. Mtengo Wogwira Ntchito: Poyerekeza ndi zida zapaipi zachimbudzi zachikhalidwe monga konkriti kapena dongo, mapaipi ozungulira arc opangidwa ndi mipiringidzo amatha kupereka ndalama zambiri pakukhazikitsa ndi kukonza.Chikhalidwe chawo chopepuka chimachepetsa ndalama zotumizira ndipo ndizosavuta kuziyika, ndikuchepetsa zofunikira zantchito.Kuonjezera apo, moyo wake wautali wautumiki komanso zofunikira zochepa zosamalira zimathandizira kuti pakhale ndalama zowononga nthawi yaitali.

a.Njira ya deoxidation imayikidwa motere: FF: Chitsulo chopha kwathunthu chokhala ndi zinthu zomangira za nayitrogeni mu kuchuluka kokwanira kumanga nayitrogeni yomwe ilipo (mwachitsanzo min. 0,020 % okwana Al kapena 0,015 % sungunuka Al). b.Kuchuluka kwa nayitrogeni sikugwira ntchito ngati mankhwala akuwonetsa kuchuluka kwa Al zomwe zili 0,020 % ndi chiŵerengero chochepa cha Al/N cha 2:1, kapena ngati zinthu zina zokwanira za N-binding zilipo.Zinthu zomangiriza za N zidzalembedwa mu Inspection Document. |
Kugwiritsa ntchito mapaipi a SSAW m'masewero:
1. Municipal Sewer Networks: Mapaipi a SSAW amagwiritsidwa ntchito nthawi zambiri pomanga mizere ya zimbudzi zazikulu zomwe zimagwiritsidwa ntchito m'malo okhala, malonda ndi mafakitale.Mphamvu zawo komanso kukana kwa dzimbiri zimawapangitsa kukhala chisankho chabwino kwambiri chotengera madzi otayira mtunda wautali.
2. Ngalande zamadzi amkuntho:Mapaipi a SSAWatha kuyendetsa bwino madzi osefukira komanso kuletsa kusefukira kwamadzi m'matauni.Kulimba kwawo kumalola kutengerako bwino kwa madzi ambiri pamitsempha yayikulu yamadzi.
3. Malo oyeretsera zimbudzi: Mapaipi a Spiral submerged arc welded angagwiritsidwe ntchito pomanga madera osiyanasiyana opangira zimbudzi, kuphatikiza mapaipi amadzi onyansa, akasinja aeration ndi machitidwe ochitira matope.Kukana kwawo ku mankhwala owononga komanso kukwanitsa kuthana ndi zovuta zosiyanasiyana kumawapangitsa kukhala ofunikira kwambiri m'malo ovuta.
Pomaliza:
Kusankha zinthu zapaipi zolondola n'kofunika kwambiri kuti ntchito yomanga bwino ndi yokonza ngalande zanu za ngalandezi.Spiral submerged arc pipe (SSAW) yatsimikizira kukhala yotsika mtengo, yokhazikika komanso yosunthika njira yothetsera zotayira zamadzi.Ndi kukana kwawo kwa dzimbiri, kapangidwe kake kosaduka, komanso kusinthika kumadera osiyanasiyana, mapaipi a SSAW amatha kunyamula bwino madzi oyipa, zomwe zimathandizira kuti mizinda ipite patsogolo.Kugwiritsiridwa ntchito kwa ma spiral submerged arc welded mapaipi m'maprojekiti a ngalande kungapangitse njira yopititsira patsogolo ngalande za ngalandezi kuti zikwaniritse zomwe zikuchulukirachulukira pakutukuka kwamatauni.
