Chitoliro cha mzere wa API 5L (Chitoliro chosasunthika ndi chowotcherera) chamagulu onse ali ndi mawonekedwe awiri a PSL1 ndi PSL2, amasiyana pakupanga mankhwala, njira zopangira, mphamvu zamakina, chithandizo cha kutentha, zolemba zoyesa, kufufuza, etc.
Mapaipi a mzere mu API 5L PSL2 ndi apamwamba kuposa PSL1
PSL ndi dzina lalifupi la mulingo wamba wazinthu.The mankhwala muyezo mlingo wa chitoliro mzere ndi PSL1 ndi PSL2, komanso tinganene mulingo khalidwe anawagawa PSL1 ndi PSL2.PSL2 ndi yapamwamba kuposa PSL1, osati muyezo woyendera womwe umasiyana, komanso katundu wamankhwala, mphamvu zamakina ndizosiyana.Chifukwa chake mukayika dongosolo la chitoliro cha mzere wa API 5L, payenera kunenedwa momveka bwino kukula kwake, magiredi awa onse, akuyeneranso kumveketsa bwino mulingo wopangira, PSL1 kapena PSL2.
PSL2 ndiyokhazikika kwambiri kuposa PSL1 pamapangidwe amankhwala, kulimba kwamphamvu, kuyesa kosawononga, komanso kuyesa kwamphamvu.
Njira zosiyanasiyana zoyesera za PSL1 ndi PSL2
API 5L PSL1 chitoliro chachitsulo chosafunikira kuti chiyesedwe.
Kwa API 5L PSL2 chitoliro chachitsulo chachitsulo, kupatula Giredi X80, magiredi ena onse a API 5L mzere chitoliro amafunikira kuyesa kwamphamvu pa kutentha kwa 0.℃.Mtengo wapakati wa Akv: longitudinal direction≥41J, njira yodutsa≥27j.
Kwa API 5L Grade X80 PSL2 line pipe, pa 0℃pakukula konse, yesani mtengo wapakati wa Akv: mayendedwe akutali≥101J, njira yodutsa≥68j.
Kuyesa kosiyana kwa hydraulic kwa API 5L mzere chitoliro mu PSL1 ndi PSL2
Kwa API 5L PSL2 mzere chitoliro adzachita mayeso hayidiroliki pa chitoliro chimodzi, ndipo mu API muyezo mfundo salola kuti mayeso Non-zowononga m'malo mayeso hayidiroliki, ichinso ndi kusiyana kwakukulu pakati Chinese muyezo ndi API 5L muyezo.Kwa PSL1 sikofunikira Kuyesa kosawononga, kwa PSL2 ipanga mayeso Osawononga papaipi iliyonse.
Mitundu yosiyanasiyana ya mankhwala a API 5L mzere chitoliro mu PSL1 ndi PSL2
Kapangidwe ka mankhwala ndi mphamvu zamakina ndizosiyananso pakati pa chitoliro cha mzere wa API 5L PSL1 ndi chitoliro cha API 5L PSL2.Kuti mudziwe zambiri monga pansipa.API 5L PSL2 ili ndi zoletsa ndi zomwe zili ndi mpweya wofanana, pomwe gawo la kaboni misa lalikulu kuposa 0.12%, ndi lofanana kapena lochepera 0.12%.Ma CEQ osiyanasiyana adzagwiritsidwa ntchito.Pakuti mzere chitoliro mu PSL2 makoma mphamvu ndi malire pazipita.Zambiri chonde onani API 5L Specification gawo 9.2 ndi 9.3.
