I-ASTM yentsimbi

I-ASTM yentsimbi
Imibhobho yensimbi idlala indima ebalulekileyo kwizicelo zemizi-mveliso, ngakumbi kumasimi ezokwakha, i-petroleum, ishishini lekhemikhali kunye nemveliso yoomatshini. Imibhobho ye-ASTM yentsimbi, oko kukuthi, imibhobho yentsimbi iveliswe ngokwemigangatho yoMbutho waseMelika ukuba uvavanywe kunye nezixhobo (i-ASTM), ukuxhathisa i-scodion kunye nokusebenza okuhle.

Umzekelo, i-ASTM A53 igubungela imibhobho yentsimbi ye-carbon yeenkqubo zokumiselwa, ngelixa i-ASTM A106 isebenza kwimibhobho yentsimbi engenamthungo yendawo yobushushu obuphezulu. Ukongeza, umgangatho we-ASTM chaza iimfuno zekharbon ebandayo ejikelezayo kunye nemibhobho yentsimbi ekhethekileyo yezakhiwo. Xa ukhetha umbhobho wentsimbi esekunene, hayi nje imigangatho yobungakanani, enjengobubanzi bodwa, ubukhulu becala, kodwa kunye nemigangatho yenqanaba, kuquka ukubekwa kwezeziciko, kufuneka kuthathelwe ingqalelo. Ngezicelo ezithile zobunjineli, kubalulekile ukukhetha i-ASTM ye-ASTM yentsimbi kunye nezixhobo zokuqinisekisa ukuzinza nokhuseleko lwesakhiwo.

Umgangatho waseMelika (Asme) useke uthotho lwemigangatho yenkcazo yemibhobho yentsimbi ukuqinisekisa umgangatho kunye nokwenza imibhobho yentsimbi. Umzekelo, i-Asme B36.10m ngumgangatho wensimbi ye-weldided kunye engenamthungo eqingqiweyo, echaza ngokweemfuno iimfuno zesayizi, izinto, inkqubo yoomatshini, inkqubo yonxibelelwano kunye neendlela zokuhlola imibhobho yentsimbi. Ngokwemigqaliselo yobukhulu, ububanzi bangaphandle bemibhobho yentsimbi engenamthungo ihlala ikwi-intshi, i-intshi enye, i-intshi enye, i-intshi ezi-2, njl. ), ezinje nge-sch 40, sch 80, njl. Ukongeza, imigangatho yombhobho ye-pie sensi yentsimbi ikwabandakanya imigangatho ye-pie, ephantsi kwenqanaba lentsimbi kunye ne-chiyiction esetyenziswe kwimibhobho yentsimbi. Iinkqubo ezahlukeneyo ze-welding kunye neenkcazo zezinto eziphathekayo zisetyenziselwa iimeko ezahlukeneyo zesicelo, ezinjengezinto zobunjineli bobunjineli kunye noxinzelelo oluphantsi. Ukuqonda le migangatho kubalulekile ukuba iinjineli kunye neengcali kuba zinxulumene ngokuthe ngqo nokhuseleko kunye nokuthembeka kweeprojekthi zobunjineli. .
