Kumvetsetsa Kusiyana Pakati pa Mapaipi a Chitsulo a ERW, SSAW, ndi DSAW

Mapaipi achitsulo ndi ofunika kwambiri pa zomangamanga za anthu masiku ano kuyambira mapaipi amafuta ndi gasi mpaka kuperekera madzi ndi ntchito zomangamanga. Pakati pawo, otchuka kwambiri ndiChitoliro cholumikizidwa cha ERW, Chitoliro chachitsulo cha SSAW, Chitoliro chachitsulo cha DSAWKudziwa kusiyana pakati pa zinthuzi kumathandiza mainjiniya, makontrakitala ndi ogula kusankha chitoliro chabwino kwambiri chomwe angagwiritsire ntchito.

Mapaipi achitsulo a ASTM A671 CC65 CL 12 EFW ogwiritsira ntchito mafakitale ndi kapangidwe kake (1)
chitoliro chotsika mphamvu1

Kodi chitoliro chachitsulo cha ERW ndi chiyani?

Chitoliro chachitsulo cha ERWlimatanthauza chitoliro chachitsulo chomwe chimapangidwa pogwiritsa ntchito welding yamagetsi yokana. Izi zimapangitsa kuti pakhale msoko wautali womwe uli kutalika kwa chitolirocho.

Izi ndi zina mwa zinthu zofunika kwambiri pa mapaipi a ERW:
M'mimba mwake: Yaing'ono mpaka yapakati (nthawi zambiri 10 mm - 508 mm).
Kukhuthala kwa Khoma: Woonda mpaka wapakati (makulidwe wamba ≤20 mm).
Mapulogalamu: Pa mapaipi amadzi, mapaipi a gasi, ndi zida zomangira ndi makina.
Ubwino: Kulondola kwakukulu, mawonekedwe osalala amkati, komanso kotsika mtengo.
Malire: Sikugwira ntchito pa ntchito ya kuthamanga kwambiri.

Kodi chitoliro chachitsulo cha SSAW n'chiyani?

SSAW (Mzere Wozungulira Wolumikizidwa ndi Arc Welded)chitoliro chachitsulo, yomwe imatchedwanso HSAW, imapangidwa popinda chingwe chachitsulo kukhala mawonekedwe ozungulira ndikulumikiza msoko pogwiritsa ntchito welding ya arc yonyowa pansi pa nthaka.

Zinthu zazikulu za mapaipi a SSAW:
M'mimba mwake: Yapakati mpaka yayikulu kwambiri (400 mm–3600 mm+).
Kukhuthala kwa Khoma: Woonda mpaka wapakati (≤25 mm wamba).
Msoko: Msoko wozungulira pa ngodya yolunjika ku mzere wa chitoliro.
Mapulogalamu: Mapaipi amafuta ndi gasi, mayendedwe amadzi, mapulojekiti akuluakulu omanga nyumba.
Ubwino: Ikhoza kupanga ma diameter akuluakulu komanso makulidwe osinthasintha a khoma.
Zoletsa: Msoko wozungulira umachepetsa mphamvu ya kuthamanga poyerekeza ndi mapaipi a DSAW a longitudinal.

Kodi chitoliro chachitsulo cha DSAW n'chiyani?

Chitoliro chachitsulo cha DSAW (Cholumikizidwa ndi Arc Yoviikidwa M'madzi Kawiri)ndi chimodzimodzi ndiChitoliro cha LSAW (Longitudinal Submerged Arc Welded)yomwe imapangidwa ndi kupindika mbale yachitsulo yokwana mainchesi 1/2 mpaka mainchesi 3 mu silinda ndikulumikiza mipata yamkati ndi yakunja pogwiritsa ntchito njira yolumikizira arc yonyowetsedwa pansi pamadzi.

Zinthu zazikulu za chitoliro cha DSAW:
M'mimba mwake: Yapakati mpaka yayikulu (300–2500 mm yokhazikika).
Kukhuthala kwa khoma: Yapakati mpaka yokhuthala (≥6 mm mpaka 50 mm+).
Gwiritsani ntchito: Mapaipi amafuta ndi gasi amphamvu kwambiri komanso mapaipi a m'mphepete mwa nyanja, ntchito zomangira zomwe zimafuna mphamvu zambiri.
Ubwino: Misomali ndi yolimba komanso yodalirika, zomwe zimapangitsa kuti nsaluyo ikhale yoyenera kwambiri pakakhala zovuta kwambiri.
ZoyipaKupanga kokwera mtengo komanso njira yopangira yochedwa poyerekeza ndi ERW ndi SSAW.

Ntchito za China Royal Steel Group

Gulu la Zitsulo Zachifumu la Chinandi katswiri wopanga zinthu zachitsulo pogwiritsa ntchito mapaipi achitsulo a ERW (Electric Resistance Welded), SSAW (Spiral Submerged Arc Welded) ndi mapaipi achitsulo a DSAW (Double Submerged Arc Welded) pakati pa ena. Kutengera zaka zambiri zaukadaulo, kampaniyo imapereka upangiri wathunthu waukadaulo ndi upangiri pa mtundu woyenera kwambiri wa mapaipi ogwiritsidwa ntchito mukutumiza mafuta ndi gasi, kutumiza madzi, ntchito zamafakitale zothamanga kwambiri, ndi mapulojekiti a mitsempha yamagazi, pakati pa ntchito zina.

Gulu la Royal Steel limaganizira zinthu zosiyanasiyana mongakukula kwa chitoliro, makulidwe a khoma, mtundu wa zinthu, kalasi ya kupanikizika, kukana dzimbiri, ndi momwe zinthu zililikuti mupeze mayankho oyenera. Kuphatikiza apo, China Royal Steel Group imapereka ntchito yopangira zinthu ndi zokutira (monga anti-crrosion, galvanization, epoxy lining) komanso chitsimikizo chapamwamba kwambiri ndi muyezo wapadziko lonse wa ASTM, ISO ndi API.

Kudzera mu kupanga kwapamwamba, kuyesa kolondola komanso kuthandizira mayendedwe, kampaniyo imatha kupereka zinthu zachitsulo zomwe zimagwirizana ndi chitetezo chokhwima, kulimba komanso miyezo yogwirira ntchito, zomwe zimathandiza makasitomala kupereka mayankho otsika mtengo, okhazikika, komanso ogwira mtima a zomangamanga.

Kusankha chitoliro chachitsulo choyenera kumadalira zofunikira pa polojekiti, kukula kwake, makulidwe a khoma, ndi kuchuluka kwa kupanikizika:

Mapaipi a ERW: Yotsika mtengo, yabwino kwambiri pa mainchesi ang'onoang'ono mpaka apakati komanso yogwiritsa ntchito mphamvu zochepa mpaka zapakati.

Mapaipi a SSAW: Yoyenera mapaipi akuluakulu okhala ndi makulidwe osinthasintha a khoma.

Mapaipi a DSAW: Njira yabwino kwambiri yogwiritsira ntchito mphamvu zambiri monga mapaipi amafuta ndi gasi omwe ali ndi mphamvu zambiri komanso kuthamanga kwambiri.

Kumvetsetsa kusiyana pakati pa mapaipi achitsulo a ERW, SSAW, ndi DSAW kumatsimikizira kuti ntchito yabwino kwambiri, chitetezo, komanso kugwiritsa ntchito bwino ndalama pa ntchito iliyonse yomanga nyumba.
