Kodi "Chitsulo cha Pipeline" ndi chiyani?

Kugwiritsa ntchito chitsulo cha payipi

Chitsulo cha payipiMitundu ya zinthuzi imaphatikizapo mapaipi achitsulo osapindika ndi mapaipi achitsulo olumikizidwa, omwe amatha kugawidwa m'magulu atatu: mapiri, madera okhala ndi sulfure yambiri ndi malo oyikidwa pansi pa nyanja. Mapaipi awa okhala ndi malo ogwirira ntchito ovuta ali ndi mizere yayitali ndipo ndi ovuta kuwasamalira, ndipo ali ndi zofunikira kwambiri paubwino.

Mavuto ambiri omwe akukumana nawo ndi zitsulo za mapaipi ndi awa: malo ambiri amafuta ndi gasi ali m'madera akumpoto, m'malo oundana, m'zipululu, ndi m'madera a m'nyanja, ndipo zachilengedwe zimakhala zovuta kwambiri; kapena kuti pakhale kuyendetsa bwino mayendedwe, kukula kwa mapaipi kumakulitsidwa nthawi zonse, ndipo kuthamanga kwa kutumiza kumawonjezeka nthawi zonse.

Katundu wa Chitsulo cha Paipi

Kuchokera ku kuwunika kwathunthu kwa momwe mapaipi amafuta ndi gasi amagwirira ntchito, momwe mapaipi amayikidwa, njira zazikulu zolephera komanso zomwe zimayambitsa kulephera, chitsulo cha mapaipi chiyenera kukhala ndi mawonekedwe abwino a makina (khoma lolimba, mphamvu yayikulu, kulimba kwambiri, kukana kutopa), komanso chiyenera kukhala ndi mainchesi akulu, chiyeneranso kukhala ndi mainchesi akulu, kusinthasintha, kukana kuzizira ndi kutentha kochepa, kukana dzimbiri (CO2), kukana madzi a m'nyanja ndi HIC, magwiridwe antchito a SSCC, ndi zina zotero.

①Mphamvu yayikulu

Chitsulo cha paipi sichimangofuna mphamvu yokoka komanso mphamvu yotulutsa, komanso chimafuna kuti chiŵerengero cha zokolola chikhale pakati pa 0.85 ~ 0.93.

② Kulimba kwambiri

Kulimba kwambiri kumatha kukwaniritsa zofunikira kuti zisawonongeke.

③Kutentha kotsika kwa kusintha kwa ductile-brittle

Madera ovuta komanso nyengo zimafuna kuti chitsulo cha mapaipi chikhale ndi kutentha kochepa kosintha kwa ductile-brittle. Malo odulidwa a DWTT (Drop Weight Tear Test) akhala chizindikiro chachikulu chowongolera kuti mapaipi asawonongeke. Mafotokozedwe onse amafuna kuti malo odulidwa a chitsanzocho akhale ≥85% pa kutentha kochepa kwambiri.

④Kukana bwino kwambiri ku ming'alu yoyambitsidwa ndi haidrojeni (HIC) ndi ming'alu yoyambitsidwa ndi sulfide (SSCC)

⑤ Kugwira ntchito bwino kwa kuwotcherera

Kutha kulumikiza bwino chitsulo ndikofunikira kwambiri kuti paipiyo ikhale yolimba komanso yolimba.
