L245 Pipeline Steel, Ndi payipi yokhazikika yomwe imachotsa mafuta, gasi, ndi madzi pansi ndikuzipereka kumakampani amafuta ndi gasi.Chitoliro cha chitoliro chimaphatikizapo chitoliro chopanda msoko ndi chitoliro chokokedwa ndi chitsulo, mapeto a chitoliro ndi mapeto athyathyathya, mapeto a ulusi ndi zitsulo;Njira yolumikizira ndikuwotcherera kumapeto, kulumikizana kwa hoop, kulumikizana kwa socket ndi zina zotero

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.

L245 Pipeline Steel, Kutentha kwa Microalloying kumagwiritsidwa ntchito popanga, mtengo wopangira zitsulo zosapanga dzimbiri zosapanga dzimbiri ndizokwera kwambiri kuposa chubu chowotcherera, komanso ndikusintha kalasi yachitsulo, monga X80 ndi pamwamba pazitsulo zamapaipi amtundu wazitsulo pamlingo wofanana ndi mpweya, ochiritsira ndondomeko ya msokonezo chubu n'zovuta kukwaniritsa zofunika owerenga;Aliyense 12Cr1moV aloyi chitoliro wopanga akugwira ntchito kafukufuku sayansi kuti patsogolo dzimbiri kukana kwa payipi yake ndi ntchito khola mu malo otsika ndi kutentha mkulu.
