Chitoliro chachitsulo cha ASTM A53 Giredi B LSAW: Mphamvu Zopangira & Mafotokozedwe a Zogulitsa

Kufotokozera Kwachidule:

Womic Steel imapereka chitoliro chachitsulo cha ASTM A53 Giredi B LSAW chapamwamba kwambiri cha mafuta, gasi, madzi, ndi nthunzi yothamanga pang'ono mpaka yapakatikati, komanso ntchito za kapangidwe ndi makina. Giredi B imapereka mphamvu yocheperako ya 240 MPa (35,000 psi) ndi mphamvu yocheperako ya 415 MPa (60,200 psi), zomwe zimapangitsa kuti ikhale giredi yapaipi yodziwika bwino kwambiri pamachitidwe a mapaipi amakampani ndi amalonda. Njira ya LSAW imaphatikizapo njira zolumikizira JCOE, UOE, ndi rolled plate, zomwe zimapereka msoko wowongoka wautali wokhala ndi khalidwe lokhazikika komanso kukhazikika kwa magawo. Pakugwiritsa ntchito makoma akuluakulu kapena olemera (mpaka makulidwe a khoma a 60mm), Womic imagwiritsa ntchito plate rolling ndi multi-pass submerged arc welding. Kunja kwa mainchesi kuyambira 219mm mpaka 1,422mm (8″ – 56″), makulidwe a khoma kuyambira 5.0mm mpaka 60mm, kutalika mpaka 24m. Chiphaso cha mphero, mayeso a hydro (ngati mukufuna kugwiritsa ntchito kapangidwe kake), mayeso a ultrasonic 100%, malekezero opindika kapena osalala, ndi zokutira zotsutsana ndi dzimbiri (FBE, 3LPE, epoxy) zilipo. Zoyenera kugwiritsa ntchito mizere yoperekera madzi, makina oponderezedwa a mpweya, kugawa mpweya wachilengedwe wochepa mphamvu, mapaipi oteteza moto, zothandizira kapangidwe kake, kuyika mipiringidzo, ndi mapaipi opangira ntchito zamafakitale.

Kukula kwa Chitoliro cha Chitsulo cha LSAW:Chipinda chakunja: 219mm – 1,422mm (8″ – 56″), Kukhuthala kwa Khoma: 5.0mm – 60mm (JCOE/UOE max 50.8mm, mbale yozungulira max 60mm), Kutalika: 6m – 18m muyezo, kutalika kwapadera mpaka 24m

Chitoliro cha Chitsulo cha LSAW Chokhazikika & Chachikulu:ASTM A53 Giredi B; komanso ASTM A53 Giredi A ikupezeka; yofanana ndi ASTM A106 Giredi B pa kutentha kwakukulu (koma dziwani kuti A106 ndi yopanda msoko); API 5L GR.B (yofanana koma yosagwirizana)

Kugwiritsa Ntchito Chitoliro cha Chitsulo cha LSAW:Kutumiza ndi kugawa madzi m'mizinda, mizere ya gasi yachilengedwe yotsika mphamvu (yosakwana 2 MPa), makina oponderezedwa mpweya, mawaya oteteza moto, mabwalo oziziritsira madzi m'mafakitale, mayendedwe a matope, zipilala zomangira ndi zomangira, kuyika zinthu zopepuka mpaka zocheperako, mizere ya nthunzi (yotsika mphamvu), kutumiza mafuta (yotsika mphamvu), mapaipi a HVAC

Chitsulo cha Womic chimapereka mitengo yapamwamba komanso yopikisana ya chitoliro chachitsulo cha ASTM A53 Giredi B LSAW, chitoliro cha kaboni cholunjika, chitoliro cha JCOE A53 GR.B, chitoliro chotsika mphamvu, chitoliro chachitsulo chomangidwa. Satifiketi ya Mill EN 10204 3.1, Kuwunika kwa weld ya UT, malekezero opindika/osalala, chophimba choteteza dzimbiri chilipo. Kupereka mwachindunji kwa mafakitale kumapulojekiti a mafakitale, a boma, ndi omangidwa padziko lonse lapansi.

1. Womic Steel: Mphamvu Zopangira ndi Mphamvu za Kampani

Womic Steel Group imagwiritsa ntchito mizere yambiri yopangira LSAW ya mapaipi a ASTM A53 Giredi B. A53 Giredi B ndi imodzi mwa miyezo yodziwika bwino ya mapaipi achitsulo cha kaboni kuti agwiritsidwe ntchito nthawi zonse. Njira ya LSAW ndi yabwino kwambiri pa mainchesi akuluakulu opitilira mtunda wa ma mphero a ERW (nthawi zambiri ERW imakhala ndi mainchesi 24 kapena 610mm). Mapaipi a LSAW a Womic amapereka njira ina yotsika mtengo m'malo mwa mapaipi opanda msoko m'ma mainchesi akuluakulu.

●Mzere wa JCOE:Pa mainchesi 406mm – 1,422mm (16″–56″), makulidwe a khoma mpaka 50.8mm.

● Mzere wa UOE:Pa mainchesi 508mm – 1,220mm (20″–48″), makulidwe a khoma mpaka 40mm.

● Mbale Yopindidwa (Msoko Umodzi):Pa mainchesi 600mm – 1,600mm (24″–63″), makulidwe a khoma mpaka 60mm.

Mphamvu yonse ya LSAW imaposa matani 300,000 pachaka, ndipo kupanga kwa A53 Giredi B kumaposa matani 120,000 pachaka. Womic Steel ili ndi ISO 9001, ndipo imatha kupereka kuwunika kwa anthu ena ndi SGS, BV, TÜV. Mbiri yapadziko lonse lapansi m'mapulojekiti amadzi am'mizinda, mafakitale, ndi zomangamanga.

Kusinthasintha kwa Kupanga kwa A53 Giredi B:

● JCOE: 406–1,422mm OD × 5.0–50.8mm WIT × ≤ 18m

2. ASTM A53 Giredi B: Kapangidwe ka Zinthu & Makhalidwe Abwino

ASTM A53 Giredi B ndi giredi ya chitsulo cha kaboni cha chitoliro cholumikizidwa komanso chosasunthika. Chimaphimba mitundu itatu: Mtundu F (wolumikizidwa ndi ng'anjo), Mtundu E (wolumikizidwa ndi mphamvu zamagetsi - ERW), ndi Mtundu S (wopanda msoko). Pa mapaipi a LSAW, tikunena za Mtundu E kapena Mtundu S? LSAW ndi wolumikizidwa pansi pa arc, womwe sukuphimbidwa momveka bwino ndi A53, koma A53 imalola njira zina zolumikizirana ngati zavomerezedwa. Mwachizolowezi, mapaipi a LSAW a A53 Giredi B amavomerezedwa kuti agwiritsidwe ntchito pa ntchito yamadzimadzi opangidwa ndi kapangidwe kake komanso otsika mphamvu kutengera mawonekedwe a makina.

Mofanana ndi ma CD a LSAW. Pa mapaipi opangidwa ndi galvanized, samalani kwambiri kuti musakandane. Pakugwiritsa ntchito njira zolumikizira madzi, zipewa za polyethylene zimalimbikitsidwa kuti zinyalala zisalowe.

10. Ubwino ndi Mafunso Ofunsidwa Kawirikawiri pa Chitsulo cha Womic - Chitoliro cha Chitsulo cha ASTM A53 Giredi B LSAW

Chifukwa chiyani Womic Steel ya A53 Giredi B?

●LSAW yayikulu mpaka 56″ - kupitirira mphamvu ya ERW

●Njira ina yotsika mtengo m'malo mwa chitoliro chopanda msoko

●Kubwerera mwachangu (masiku 20-30 mwachizolowezi)

●Zosankha zophikira zosinthasintha (3LPE, FBE, galvanized, primer)

●Kuwunika kwa chipani chachitatu kulipo

Mafunso Ofunsidwa Kawirikawiri:

Q: Kodi ASTM A53 Giredi B ndi yoyenera kugwiritsa ntchito mipope yamadzi?
A: Inde, ndiye muyezo wofala kwambiri wotumizira ndi kugawa madzi m'matauni. Pa madzi akumwa, onetsetsani kuti chophimba kapena chophimbacho chili choyenera (cholimbikitsidwa ndi epoxy lining). Pa madzi osaphika kapena othirira, chitoliro chosavuta ndi chovomerezeka.

Q: Kodi chitoliro cha A53 Grade B LSAW chingagwiritsidwe ntchito popanga gasi wachilengedwe?
A: Inde, pogawa mphamvu yotsika (nthawi zambiri pansi pa 2 MPa). Pa mphamvu yokwera, API 5L GR.B kapena X42 ndi yofunikira. Nthawi zonse yang'anani ma code am'deralo.

Q: Kodi kusiyana pakati pa ASTM A53 Giredi B ndi API 5L GR.B ndi kotani?
A: Ali ndi mphamvu zofanana ndi za makina (240 MPa poyerekeza ndi 245 MPa). API 5L ili ndi malire okhwima a chemistry (otsika P, S) komanso mayeso okhwima a mapaipi olumikizirana. Pakugwiritsa ntchito madzi ndi kapangidwe kake, A53 ndi yokwanira. Pa mapaipi amafuta ndi gasi, API 5L ndi yabwino kwambiri.

Q: Kodi A53 imafuna mayeso a hydrostatic?
A: ASTM A53 imafuna mayeso a hydrostatic a chitoliro chopanda msoko (Mtundu S) ndi chitoliro cha ERW (Mtundu E) zikafotokozedwa. Pa mapaipi a LSAW opangidwa ku A53, mayeso a hydrotest nthawi zambiri amachitidwa pokhapokha ngati dongosololo lafotokozedwa. Magwiritsidwe ambiri amadzi okhala ndi kapangidwe kake komanso otsika mphamvu savomereza mayeso a hydrotest.

Q: Kodi mungapereke A53 Giredi B ndi galvanizing yotentha?
A: Inde. Timapereka ma galvanizing otentha pa ASTM A123. Kutalika kwakukulu kwa 12.5m. Pa mapaipi ataliatali, tikupangira ma galvanizing a sectional kapena primer.

Q: Kodi nthawi yogwiritsira ntchito chitoliro cha A53 Grade B LSAW ndi yotani?
A: Masiku 20-30 a kukula koyenera. Kwa ma diameter akuluakulu kapena khoma lolemera, masiku 35-45.

●OD 1,067mm (42″) × Kulemera 10.0mm – 18,000 mamita (pafupifupi matani 4,700) – mbale yozungulira
Zonse:Mamita 42,000 (42 km), pafupifupi matani 10,100

Mafotokozedwe:Malekezero opanda kanthu okhala ndi mtsempha wa rabara, chophimba chakunja cha 3LPE (2.5mm), mkati mwa epoxy lining (400 microns) cha madzi akumwa. Mayeso ophwanyika, mayeso opindika motsogozedwa, 100% UT ya msoko wothira. Palibe mayeso a hydrostatic (mayeso ovomerezeka ndi kasitomala NDT kuphatikiza mayeso a kuthamanga kwa nthaka). Kuyang'aniridwa ndi chipani chachitatu ndi SGS USA.

Ntchito:Chida chachikulu chotumizira madzi kuchokera ku Nyanja ya Houston kupita ku fakitale yatsopano yoyeretsera madzi, chomwe chimapereka chithandizo kudera lomwe likukula kumpoto kwa Houston. Kupanikizika kwa ntchito ndi 0.8 MPa. Dothi: dongo ndi mchenga zomwe zimatha dzimbiri pang'ono.

Mavuto ndi Mayankho a Ukadaulo:

●Chipinda chamkati cha madzi akumwa:Epoxy lining (400 microns) yadutsa NSF/ANSI 61.

●Chophimba chakunja cha 3LPE cha nthaka yowononga:3LPE yokhala ndi FBE primer, kuzindikira nthawi yopuma pa 5kV popanda kulephera. Mphamvu yochotsa pa 25°C: 220 N/cm.

●Zolumikizira za gasket za rabara (kumanga munda):Kulekerera kwa OD ±0.3% kwapezeka (zenizeni 0.2-0.3%).

●Kukonza zinthu kuti zigwirizane ndi zomangamanga zosiyanasiyana:Kutumiza nthawi yomweyo kwa miyezi inayi.

● Zotsatira:Paipi idayikidwa mu kotala lachiwiri la 2024. Mayeso a kuthamanga adapambana pa 1.2 MPa. Palibe kutuluka kwa madzi patatha miyezi 6. Kasitomala adalamula mtunda wowonjezera wa 25 km pa gawo lachiwiri.
