Chitoliro cha API Chopanda Msoko vs. Welded: Ndi Chiti Chosankha?

Mu mapulojekiti ofunikira kwambiri monga malo obowolera mafuta m'mphepete mwa nyanja, mafakitale opanga mankhwala, kapena mapaipi a gasi amphamvu kwambiri mumzinda, mapaipi ndiye maziko a polojekitiyi.Chitoliro chachitsulo cha API 5Lmuyezo, mkanganowu nthawi zambiri umayang'ana pa njira ziwiri zazikulu:chitoliro chachitsulo chosasunthikandichitoliro chachitsulo choswedwa(ERW/LSAW).

Kusankha njira yolakwika yoyendetsera mapaipi si nkhani yongofuna ndalama zokha, komanso nkhani ya chitetezo ndi moyo wautali. Pansipa pali chitsogozo chokwanira chokuthandizani kupeza njira yoyenera yogwiritsira ntchito njira yanu.

Kumvetsetsa Kusiyana kwa Kupanga Zinthu

Kusiyana kwakukulu pakati pa mapaipi achitsulo chosasunthika ndi mapaipi achitsulo olumikizidwa kuli mu njira zawo zopangira.

Mapaipi achitsulo opanda msoko (SMLS)

Mapaipi achitsulo opanda msoko amapangidwa pogwiritsa ntchito mabowo obowola mu chipolopolo chachitsulo chozungulira cholimba pogwiritsa ntchito njira yopangira mandrel. Chifukwa palibe kuwotcherera, kuzungulira kwa chitolirocho ndi kofanana kwathunthu.

Ubwino:Kukana kuthamanga kwambiri, kudalirika kwambiri, kufanana bwino kwa geometri (kuzungulira kwambiri).

Zoyipa: Mtengo wokwera wopanga, nthawi yayitali yotumizira mapaipi akuluakulu.

 

Mapaipi achitsulo olumikizidwa (ERW, LSAW, SSAW)

Mapaipi achitsulo olumikizidwa amapangidwa ndi ma billets achitsulo, ma coil, kapena mbale. Billet imakulungidwa mu chitoliro kenako imalumikizidwa pogwiritsa ntchito welding yolimba kwambiri (ERW) kapena welding yozama pansi pa nthaka (LSAW).

Ubwino:Kugwira ntchito bwino pamtengo, kumapezeka m'ma diameter akuluakulu, ndipo nthawi zambiri makulidwe a khoma ndi ofanana (kulekerera).

Zoyipa:Msoko wothira zitsulo nthawi zonse umaonedwa ngati "malo ofooka," ngakhale kuti kuyesa kwamakono kwachepetsa kwambiri lingaliro limeneli.

Kupanikizika ndi Kutentha: Mfundo Zofunika Kuziganizira

Mikhalidwe yogwirira ntchito iyenera kukhala yofunika kwambiri posankha zochita.

Kugwiritsa ntchito mphamvu yothamanga kwambiri:Machubu opanda msoko ndiye muyezo wogwiritsira ntchito mphamvu yamphamvu kwambiri. Popeza palibe ma weld a longitudinal, palibe chiopsezo cha "kulephera kwa weld."Ngati ntchito yanu ikufuna kupanikizika kopitilira 2,000 PSI, kuyika mapaipi osasemphana ndi njira yabwino kwambiri.

Malo okhala ndi asidi/kuwononga:M'malo okhala ndi asidi (okhala ndi hydrogen sulfide), ma weld a chubu cholumikizidwa amakhala osavuta kugwidwa ndi stress corrosion cracking (SCC). Ngakhale machubu olumikizidwa apamwamba kwambiri amathandizidwa mwapadera kuti asawonongeke ndi dzimbiri,mapaipi opanda msokoIli ndi ubwino wachilengedwe pakugwirizana kwa mankhwala ndipo motero imapirira kwambiri.

Chitoliro cha API 5L Chitoliro Chofunikira Kwambiri Pakuyendetsa Mphamvu

Kukula ndi Kukula

Chisankho chanu chingapangidwe chifukwa cha inu kutengera kokha mtunda wofunikira wakunja (OD).

Mtundu wa chitoliro Kukula Kwachizolowezi Mlandu Wabwino Kwambiri Wogwiritsira Ntchito
Wopanda msoko 1/8" mpaka 26" Mizere yothamanga kwambiri, yaing'ono mpaka yapakati.
Wolukidwa (ERW) 2" mpaka 24" Kuthamanga kochepa mpaka pakati, mayendedwe akutali.
Wolukidwa (LSAW) 16" mpaka 60"+ Kutumiza kwakukulu kwa mainline, ma structural pilings.

 

Ngati mukufunaMainchesi 48Chitoliro chachikulu cha payipi ya gasi yodutsa dziko lonse, chopanda msoko sichingatheke kupanga kukula koteroko. Mudzafika paLSAW (Longitudinal Submerged Arc Welded) kapena chitoliro cha SSAW (Spiral).

Kusanthula kwa Mtengo ndi Phindu

Pamitengo yamakono,Chitoliro cholumikizidwa ndi chotsika mtengo pafupifupi 20% mpaka 30% kuposa chubu chachitsulo chosasunthika cha kukula kofanana ndi mtundu womwewo..

Nthawi yosungira:Ngati mukufuna kunyamula madzi, kusonkhanitsa mafuta ndi gasi pogwiritsa ntchito mphamvu yochepa, kapena kungofuna mapaipi omangira, chitoliro cholumikizidwa ndiye njira yotsika mtengo kwambiri.

Nthawi yoti muyike ndalama zambiri:Mu makina oti aphedwe kapena kufa, mapaipi amagetsi, kapena malo otentha kwambiri m'mafakitale opangira magetsi, mtengo wowonjezera wa mapaipi osasunthika ndi wofanana ndi inshuwalansi yoti asawonongeke kwambiri.

Miyezo Yabwino: API 5L Factor

Kupereka kwa magiredi sikunakhudzidwe (ngakhale kuti magiredi a PSL1 ndi PSL2 amasiyana). Chitsulo chopanda msoko komanso chotha kuwotcherera chiyenera kukwaniraAPI 5L PSL1 PSL2magiredi ofotokozera zinthu.

PSL1: Ubwino wokhazikika wa ntchito zonse.

PSL2: Zofunikira kwambiri pakupanga mankhwala, kulimba kwa notch, ndi mawonekedwe a makina. Mapulojekiti ambiri akunja ndi amphamvu kwambiri amafuna kugwiritsa ntchito chitsulo chosasunthika cha PSL2.

Pomaliza: Ndi iti yomwe muyenera kusankha?

Chitoliro Chopanda Msoko Chitsulo:Ngati muli m'malo okhala ndi mpweya wothamanga kwambiri, nthunzi yotentha kwambiri, kapena nyanja yakuya, kukonza sikungatheke ngati zinthu zalephera.

Chitoliro Chosemedwa ndi Chitsulo:Ngati mukugwira ntchito pa ntchito yaikulu yomwe imafuna mphamvu yapakati, muyenera mapaipi okhala ndi mainchesi oposa 24 m'mimba mwake, kapena muli ndi bajeti yochepa yogwiritsira ntchito ndalama.

Malangizo a Akatswiri:Musanamalize mndandanda wanu wogula zinthu, funsani katswiri wa mapulojekiti kapena wogulitsa wodziwa bwino ntchito kuti ayang'anenso "magawo anu opangira." Mapaipi oyenera sayenera kukhala ndi mphamvu zokwanira zokha komanso kuonetsetsa kuti ali otetezeka komanso otchipa.

Lowetsani zofunikira pa polojekiti yanu kuti mudziwe zambiri za tsatanetsatane ndi zomwe muyenera kuganizira pa polojekiti yanu.
