Zodziwika bwino
API 5Lkawirikawiri amatanthauza muyeso kuphedwa kwa mapaipi zitsulo zitsulo.Mapaipi azitsulo amaphatikizapo mapaipi achitsulo opanda msoko ndi mapaipi achitsulo otsekemera.Pakalipano, mitundu yomwe imagwiritsidwa ntchito kwambiri pamipaipi yamafuta imaphatikizapo spiral submerged arc welded chitoliro (SSAW), msoko wowongoka pansi pamadzi arc welded chitoliro (LSAW), ndi chitoliro chotchinga chamagetsi (RW).Mipope yachitsulo yopanda msoko nthawi zambiri imasankhidwa pomwe m'mimba mwake wa chitoliro ndi wosakwana 152mm.
Mapaipi amtundu wa GB/T 9711-2011 azitsulo zamapaipi amafuta ndi gasi amapangidwa kutengeraAPI 5L.
GB/T 9711-2011 imatchula zofunikira popanga mapaipi achitsulo osasunthika ndi mapaipi azitsulo otenthedwa pamilingo iwiri yodziwika bwino yazinthu (PSL1 ndi PSL2) zomwe zimagwiritsidwa ntchito pamapaipi amafuta ndi gasi.Choncho, muyezo uwu umangogwira ntchito pa mapaipi opanda zitsulo ndi ma welded zitsulo zoyendetsa mafuta ndi gasi, ndipo sizikugwira ntchito pazitsulo zachitsulo.
Chitsulo kalasi
The zopangira zitsulo makalasi aAPI 5Lmapaipi zitsulo monga GR.B, X42, X46, X52, X56, X60, X70, X120 pipeline zitsulo.Zosiyanasiyana zitsulo mipope mipope zitsulo ndi zofunika zosiyanasiyana zopangira ndi kupanga, koma ofanana mpweya pakati kalasi osiyana zitsulo amalamulidwa mosamalitsa.
Quality Standard
Mu API 5L chitsulo chitoliro muyezo, miyezo khalidwe (kapena zofunika) mapaipi zitsulo amagawidwa PSL1 ndi PSL2.PSL ndi chidule cha mlingo specifications mankhwala.
PSL1 amapereka ambiri payipi zitsulo chitoliro khalidwe mlingo zofunika;PSL2 imawonjezera zofunikira pakuphatikizidwa kwamankhwala, kulimba kwa notch, mphamvu zamphamvu ndi NDE yowonjezera.
Chitoliro chachitsulo chachitsulo cha PSL1 chitoliro chachitsulo (dzina losonyeza mphamvu ya chitoliro chachitsulo, monga L290, 290 chimatanthawuza mphamvu zochepa zokolola za thupi la chitoliro ndi 290MPa) ndi kalasi yachitsulo (kapena kalasi, monga X42, kumene 42 imayimira mphamvu zochepa zokolola kapena bwalo lapamwamba Mphamvu zochepa zokolola za chitoliro chachitsulo (mu psi) ndizofanana ndi zitoliro zachitsulo Zimapangidwa ndi zilembo kapena nambala yosakanikirana ya zilembo ndi manambala omwe amadziwika ndi mphamvu chitoliro chachitsulo, ndipo kalasi yachitsulo ikugwirizana ndi mankhwala achitsulo.
Mipope yachitsulo ya PSL2 imapangidwa ndi zilembo kapena kuphatikiza zilembo ndi manambala omwe amagwiritsidwa ntchito pozindikira mphamvu ya chitoliro chachitsulo.Dzina lachitsulo (chitsulo kalasi) limagwirizana ndi mankhwala achitsulo.Zimaphatikizanso chilembo chimodzi (R, N, Q kapena M) chimapanga chiganizo, chomwe chimasonyeza momwe akuperekera.Kwa PSL2, pambuyo pa malo operekera, palinso chilembo S (malo ogwiritsira ntchito asidi) kapena O (malo ogwirira ntchito zam'madzi) akuwonetsa momwe ntchito ikuyendera.
