API 5L nthawi zambiri imatanthawuza kukhazikitsidwa kwa mapaipi achitsulo, omwe amaphatikizapo magulu awiri akulu:mapaipi opanda zitsulondiwelded zitsulo mapaipi. Pakadali pano, mitundu yomwe imagwiritsidwa ntchito kwambiri pamapaipi amafuta omwe amagwiritsidwa ntchito kwambiriozungulira kumizidwa arc welded mapaipi(PAPA),ma longitudinal kumizidwa arc welded mapaipi(LSAW PIPE), ndimagetsi kukana welded mapaipi(ERW). Mipope yachitsulo yopanda msoko nthawi zambiri imasankhidwa pomwe m'mimba mwake wa payipi ndi wosakwana 152mm.
Muyezo wadziko lonse wa GB/T 9711-2011, Mapaipi achitsulo a Pipeline Transportation Systems mu Petroleum and Natural Gas Industries, adapangidwa kutengera API 5L.
GB/T 9711-2011 imatchula zofunikira pakupanga mapaipi achitsulo opanda msoko ndi owotcherera omwe amagwiritsidwa ntchito pamapaipi amafuta ndi gasi wachilengedwe, kutengera magawo awiri azinthu (PSL1 ndi PSL2). Choncho, muyezo uwu umangogwira ntchito pamapaipi achitsulo osasunthika komanso otsekemera amafuta ndi gasi ndipo sagwira ntchito pamapaipi achitsulo.
Maphunziro a Zitsulo
Mipope yachitsulo ya API 5L imagwiritsa ntchito magiredi osiyanasiyana opangira zinthu kuphatikiza GR.B, X42, X46, X52, X56, X60, X70, X80, ndi ena. Zitsulo zamapaipi okhala ndi giredi X100 ndi X120 tsopano zapangidwa. Mitundu yosiyanasiyana yachitsulo imayika zofunikira pazakudya komanso njira zopangira.
Milingo Yabwino
Muyeso wa API 5L, chitsulo chapaipi chapaipi chimagawidwa kukhala PSL1 kapena PSL2. PSL imayimira Mlingo wa Mafotokozedwe a Zamalonda.
PSL1 imatchula zofunikira zonse zazitsulo zamapayipi; PSL2 imawonjezera zofunikira pakuphatikizidwa kwamankhwala, kulimba kwa notch, mphamvu zamphamvu, komanso kuyesa kowonjezera kwa NDE.
