L360 payipi zitsulo mwambo processing payipi zoyendera chitoliro
L360 Pipeline Steel, Cholinga: API SPEC 5L-2011 (Mafotokozedwe a Pipeline), opangidwa ndi kufalitsidwa ndi American Petroleum Institute, amagwiritsidwa ntchito padziko lonse lapansi.Chitoliro: Kunyamula mafuta, gasi kapena madzi kuchokera pansi kudzera pa mapaipi kupita kumakampani amafuta ndi gasi.Chitoliro chitoliro zikuphatikizapo opanda msokonezo ndi welded chitoliro mitundu iwiri, mapeto chitoliro ali lathyathyathya mapeto, ulusi mapeto ndi zitsulo mapeto;Njira yolumikizira ndikuwotcherera kumapeto, kulumikizana kwa hoop, kulumikizana kwa socket ndi zina zotero.Zinthu zazikulu za chubu ndi B, X42, X46, X56, X65, X70 ndi kalasi ina yachitsulo.Kampani yathu idapambana chiphaso cha API (API 5CT ndi API 5L) mu Ogasiti 2009.
L360 Pipeline Steel, API SPEC 5L GB/T9711.1 GB/T9711.2 China National Standard Application: Mapaipi a oxygen, madzi ndi mafuta mumakampani amafuta ndi gasi B, X42, X52, X60, X65, X70 L245 L290 L320 L360 L390 L450 L485
Ndi chitukuko cha payipi zitsulo mbale luso ndi kupita patsogolo kwa welded chitoliro kupanga, luso kuwotcherera, ntchito osiyanasiyana chitoliro ndi welded chitoliro mu kukula pang'onopang'ono, makamaka lalikulu m'mimba mwake welded chitoliro kalasi kukula ubwino zoonekeratu, ndi zinthu mtengo, welded chitoliro wakhala lalikulu m'munda wa mzere chitoliro, amene amalepheretsa chitukuko cha zitsulo zosapanga dzimbiri zitsulo mzere chitoliro.Mu 2004, kutulutsa kwa mapaipi opanda msoko ndi pafupifupi 400,000 t, kalasi yachitsulo imaphatikizapo X42-70, ndipo mitunduyo ndi mapaipi am'mphepete mwa nyanja ndi mapaipi apamadzi.
Kupanga mkulu zitsulo kalasi payipi chitoliro utenga microalloying Kutentha njira mankhwala, mtengo kupanga zitsulo zosapanga dzimbiri chitoliro mosalekeza mwachionekere apamwamba kuposa welded chitoliro, ndi kusintha kalasi zitsulo, monga X80 ndi pamwamba zitsulo kalasi payipi malire chitoliro pa ofanana mpweya. , ndondomeko yachizolowezi ya chitoliro chopanda msoko ndizovuta kukwaniritsa zofunikira za ogwiritsa ntchito;Aliyense wopanga chitoliro cha aloyi a 12Cr1moV akugwira ntchito yofufuza zasayansi kuti apititse patsogolo kukana kwa chitoliro cha mapaipi ake komanso kugwira ntchito mokhazikika m'malo otsika komanso otentha kwambiri.
