Kusiyana pakati pa chitoliro cha LSAW ndi chitoliro cha SSAW

Kupanga mapaipi a API LSAWnjira

Chitoliro cholumikizidwa cha arc cholumikizidwa ndi longitudinal (Chitoliro cha LSAW), yomwe imadziwikanso kuti chitoliro cha SAWL. Imagwiritsa ntchito mbale yachitsulo ngati zopangira, zomwe zimapangidwa ndi makina opangira, kenako kuwotcherera kwa arc yonyowa pansi pa nthaka kumachitika mbali zonse ziwiri. Kudzera mu njirayi, chitoliro chachitsulo chonyowa pansi pa nthaka chonyowa pansi pa nthaka chidzakhala ndi ductility yabwino kwambiri, kulimba kwa kuwotcherera, kufanana, pulasitiki komanso magwiridwe antchito abwino otsekera.

 

Makulidwe ndi mawonekedwe a chitoliro chachitsulo cholumikizidwa ndi arc cholumikizidwa ndi mainchesi awiri

M'mimba mwake wa mapaipi olumikizira arc omwe ali pansi pa nthaka nthawi yayitali ndi waukulu kuposa wa mapaipi olumikizira okana, nthawi zambiri amakhala mainchesi 16 mpaka 60, 406mm mpaka 1500 mm. Ali ndi mphamvu yolimba komanso mphamvu yotsika ya dzimbiri.

JINDALAI Ali ndi machubu a LSAW ogulitsidwa.

 

Kugwiritsa ntchitoLSAW chitoliro

Yagwiritsidwa ntchito kwambiri m'mapaipi amafuta ndi gasi, makamaka mapaipi okhala ndi mainchesi akuluakulu, khoma lokhuthala, mphamvu yayitali komanso mtunda wautali. Nthawi yomweyo, malinga ndi zomwe API ikunena, mapaipi a LSAW (mapaipi a SAWL kapena mapaipi a JCOE) amagwiritsidwa ntchito makamaka ponyamula mafuta ndi gasi m'malo akuluakulu, ndipo ndi oyenera mapaipi odutsa mizinda, nyanja ndi madera akumatauni. Ili ndi gawo 1 ndi gawo 2.

 

Ukadaulo wopanga chitoliro cha SSAW (chitoliro cha HSAW)

Chitoliro cha SSAW, chomwe chimadziwikanso kuti HSAW PIPE, chili ndi mzere wolumikizira wozungulira. Chimagwiritsa ntchito ukadaulo wolumikizira wozungulira womwewo monga kulumikiza kwa arc longitudinal submerged. Kusiyana kwake ndikuti mapaipi a SSAW amalumikizidwa mozungulira, pomwe mapaipi a LSAW amalumikizidwa mozungulira. Njira yopangira ndikuzungulira mzere wachitsulo, kuti njira yozungulira ipange ngodya yolunjika pakati pa payipi, ndipo imapangidwa ndikulumikizidwa, kotero kuti weld imakhala yozungulira.

 

 

Kukula ndi mawonekedwe a chitoliro cha SSAW (chitoliro cha HSAW)

Mapaipi a SSAW ali ndi mainchesi 20 mpaka mainchesi 100, ndi 406 mm mpaka 2540 mm. Ubwino wake ndi wakuti titha kupeza mapaipi a SSAW okhala ndi mainchesi osiyanasiyana pa mzere wachitsulo wofanana, womwe umagwiritsidwa ntchito kwambiri mu mzere wachitsulo, ndipo kupsinjika koyambirira kuyenera kupewedwa mu weld, yomwe ili ndi magwiridwe antchito abwino opirira kupsinjika.

Vuto lake ndilakuti kukula kwake sikuli bwino, ndipo kutalika kwa weld ndikutalika kuposa kutalika kwa chitoliro, zomwe zimapangitsa kuti pakhale ming'alu, ma pores, slag include, weld yapafupi, mphamvu ya weld ikagwedezeka ndi zolakwika zina.

Pa makina opangira mafuta ndi gasi, koma mu malamulo opanga mafuta, mapaipi a SSAW / HSAW angagwiritsidwe ntchito m'madera a Giredi 3 ndi Giredi 4 okha. Kapangidwe ka nyumba, mayendedwe amadzi ndi kuyeretsa zinyalala, makampani opanga kutentha, zomangamanga, ndi zina zotero.

Chubu cha LSAW chimagwira ntchito bwino kuposa chubu cha SSAW.

 

Monga tafotokozera pamwambapa, mafotokozedwe a machubu onse awiri a SAW amatanthauza kuti machubu a SSAW adzagwiritsidwa ntchito m'magawo osafunikira kwenikweni. Pakadali pano, United States, Japan ndi Germany onse amatsutsa mapaipi a SSAW, ndipo palibe lingaliro loti mapaipi a SSAW agwiritsidwe ntchito m'mapaipi ofunikira. Mapaipi ena amagwiritsa ntchito mapaipi a SSAW. Russia ili ndi mapaipi ochepa mu SSAW, ndipo apanga malamulo okhwima ogwiritsira ntchito. Ku China, chifukwa cha zinthu zakale, mapaipi ambiri ofunikira ku China amagwiritsabe ntchito mapaipi a SSAW.

 

Poyerekeza ndi chitoliro chopanda msoko ndi chitoliro cha ERW, mapaipi a ERW ndi SAW amagwiritsidwa ntchito makamaka ponyamula mafuta ndi gasi. Mapaipi achitsulo chopanda msoko amagwiritsidwa ntchito makamaka pobowola mafuta ndi gasi komanso kufufuza.

 

Ngati mukuganiza zakugula chitoliro cha SSAW kapena chitoliro cha LSAW, onani zosankhaJINDALAIali ndi kwa inu ndipo ganizirani kulumikizana ndi gulu lathu la kuti mudziwe zambiri. Tikukupatsani yankho labwino kwambiri pa ntchito yanu. Plendi musazengereze kulankhulana nafe:
