GB/T 9948-2013 Grade 1Cr2Mo Petroleum Cracking iMibhobho Imibhobho yentsimbi engenamthungo

Inkcazelo emfutshane:

Umbhobho oqhekezayo wepetroleum ngumbhobho wentsimbi omde, ongqukuva ongenamthungo.Ukusetyenziswa kwepayipi yepetroleum yokuqhekeka: Isetyenziselwa ukuthutha i-petroli, i-kerosene, ioli ye-diesel kunye nezinye iimveliso zeoli, ezinokuxhathisa ukubola kunye nokugqoka.Umbhobho wokuqhekeka kwe-petroleum (gb9948-83) ngumbhobho wentsimbi weklasi yokuqala ofanelekileyo ukugaya i-geological drilling kunye ne-industrial drilling.

Intshayelelo yemveliso

Umbhobho wokuqhekeka wepetroleum wokusika ukuthengisa, ukusetyenzwa kombhobho wokuqhekeka kwepetroleum, umbhobho wokuqhekeka wepetroleum usetyenziswa ikakhulu ukwenza uxinzelelo oluphezulu kunye nombhobho webhoyila woxinzelelo ongaphezulu komgangatho ophezulu wekhabhoni yesakhiwo sentsimbi, ialloyi yentsimbi kunye nentsimbi ekwaziyo ukumelana nobushushu obuphezulu ityhubhu engenamthungo, ezi. Iityhubhu zebhoyila zisebenza phantsi kobushushu obuphezulu kunye noxinzelelo, ityhubhu ekwindima yegesi ephezulu yobushushu kunye nomphunga wamanzi nayo iya kuba yi-oxidation kunye ne-corrosion, ngoko ke umbhobho wokuqhekeka wepetroleum kufuneka ube namandla aphezulu ahlala ngoko ke, ityhubhu yokuqhekeka kwepetroleum babe namandla okunyamezela okuphezulu, ukuxhathisa okuphezulu kwe-oxidation, kunye nokuzinza okuhle kombutho.

Ukuqina kombhobho wokuqhekeka kwepetroleum kunempembelelo enkulu kwiipropati zomatshini, kodwa akuzona zonke iindawo zomatshini kufuneka zibe nzima ngokupheleleyo.Umzekelo, ukugoba, iinxalenye zeshafti yoxinzelelo lwe-torsion, iindawo zokunyanga ubushushu bomphezulu, njl.njl., zifuna kuphela ubunzulu obuthile bomaleko obunzima ukuhlangabezana neemfuno zokusetyenziswa.Ukucinywa kombhobho wepetroleum wokuqhekeka kumiselwa ikakhulu yinqanaba lokupholisa elibalulekileyo, elincinci izinga lokupholisa elibalulekileyo, ngcono ukucinywa kombhobho wokuqhekeka kwepetroleum, kwaye ngokuchaseneyo, ukucinywa kombhobho wokuqhekeka kwepetroleum.Ukongeza kwi-Co, uninzi lwezinto ezidibanisayo zinokuphucula kakhulu ukuqina kwentsimbi.

Intshayelelo yeMarike

I-Petroleum cracking pipe market up and down, umdlalo omde kunye nomfutshane unzima, imarike ixubene ne-bearish, ekwakhokelela ekukhuleni kwemoya yokulinda nokubona, imfuno yemarike yamiswa.Njengomhla wokugqibela wokurhweba ngaphambi kokuba amaxabiso eeholide aphantsi, kwaye akukho rhwebo lwexesha elizayo ngexesha leeholide, ngoko ke, imarike yavulwa kwixesha elizayo le-10 isekhona ukuqhubeka kokwehla kwenzeka.Ukuba ikamva lihamba lisezantsi, ngokungabikho kweendaba ezilungileyo zokunyusa amathuba okuba i-petroleum cracking spot spot market ilandele ukuhla, amaxabiso emibhobho yokuqhekeka kwepetroleum kulindeleke ukuba aqhube buthathaka.
