Seamless zitsulo chitoliro Kalasi ndi Zinthu Zofunika

Chitoliro chachitsulo chosasunthika cha kaboni chimatanthawuza chitoliro chopangidwa ndi chitsulo cha kaboni popanda zolumikizira zowotcherera kapena seam, ndipo billet yolimba imatulutsidwa kudzera mukufa kuti ipange chitoliro cha mawonekedwe ndi kukula kwake.Chitoliro chachitsulo chosasunthika cha kaboni ndi chodziwika bwino chifukwa cha kulimba kwake, kulimba kwamphamvu komanso kukana dzimbiri, ndikupangitsa kuti ikhale yabwino m'mafakitale osiyanasiyana kuphatikiza mafuta ndi gasi, magalimoto ndi zomangamanga.

Chimodzi mwazinthu zodziwika bwino za carbon seamless steel chitoliro ndiA106 Gulu B, yomwe ndi muyezo wa ASTM wa chitoliro chopanda mpweya cha chitsulo chosapanga dzimbiri pa ntchito yotentha kwambiri.Ili ndi mpweya wochuluka wa 0.30%, ndikupangitsa kuti ikhale yabwino kwa mapulogalamu omwe amafunikira kutentha kwakukulu ndi kupanikizika.Ndiwoyeneranso kupanikizika kochepa komanso kutentha kwapansi, komanso kuwotcherera ndi kuwotcha.

Gulu lina lodziwika bwino ndiAPI 5L Gulu B, womwe ndi muyeso wa chitoliro chachitsulo chosasunthika komanso chowotcherera pamapaipi otumizira mapaipi mumakampani amafuta ndi gasi.Ili ndi mpweya wambiri wa 0.30%, womwe umaupanga kukhala wabwino kuti ugwiritsidwe ntchito m'malo othamanga kwambiri komanso kutentha kwambiri.

Kuphatikiza pa kalasi, zinthu za carbon seamless steel pipe ndizofunikanso kwambiri.Zipangizo zodziwika bwino zimaphatikizapo SAE 1020, yomwe imakhala ndi mpweya wochepa kwambiri ndipo ndi yabwino kuti ikhale yopindika, yopendekera ndi yofanana ndi kupanga, ndi SAE 1045, yomwe ili ndi mpweya wambiri wa carbon ndipo ndi yabwino kwa mapulogalamu omwe amafunikira kuuma, kulimba komanso kukana kuvala.

Zida zina ndi monga ASTM A519 Grade 4130 ya mizere yothamanga kwambiri ya hydraulic ndi chubu la mafuta, ndi ASTM A106 Grade C yokhala ndi mpweya wambiri wa 0.35% pamapulogalamu omwe amafunikira kukana kwa dzimbiri.

Pomaliza, mapaipi achitsulo osasunthika a carbon ndi ofunikira m'mafakitale osiyanasiyana ndipo kusankha kalasi ndi zinthu kumadalira ntchito yeniyeni.A106 Grade B ndi API 5L Grade B ndi magiredi otchuka, pomwe zida monga SAE 1020, SAE 1045,Chithunzi cha ASTM A519-4130, ndi ASTM A106 Grade C ndi zosankha zotchuka.
