Umbhobho ongenamthungo we-A106
Umbhobho wentsimbi engenamthungo we-ASTM A106 ngumbhobho wentsimbi engenamthungo oqhelekileyo waseMelika owenziwe ngochungechunge lwentsimbi yekhabhoni eqhelekileyo.
Intshayelelo yeMveliso
Umbhobho wentsimbi engenamthungo we-ASTM A106 ngumbhobho wentsimbi engenamthungo owenziwe ngezinto zesinyithi sekhabhoni saseMelika. Ngumcu omde wentsimbi onecandelo elinqamlezileyo elingenanto kwaye akukho malungu ajikeleze umngcelele. Imibhobho yentsimbi inecandelo elinqamlezileyo elingenanto kwaye isetyenziswa kakhulu njengemibhobho yokuthutha ulwelo, ngokuqhelekileyo kwiindawo ezinobushushu obuphezulu kunye noxinzelelo oluphezulu. Imibhobho yentsimbi engenamthungo ye-ASTM A106 inokwahlulwa ibe yimibhobho eqengqelekayo eshushu, imibhobho eqengqelekayo ebandayo, imibhobho etsalwa ebandayo, imibhobho ekhutshiweyo, njl. ngokweendlela ezahlukeneyo zemveliso. Imibhobho engenamthungo eqengqelekayo eshushu ngokubanzi iveliswa kwiiyunithi zokuqengqeleka kwemibhobho ezenzekelayo. Umbhobho oqinileyo uyahlolwa kwaye iziphene zomphezulu ziyasuswa, zisikwe zibe bubude obufunekayo, zibekwe phakathi kobuso bomphetho wetyhubhu engenanto engenanto, emva koko zithunyelwe kwisithando sokufudumala ukuze zifudumale, kwaye zigqobhozwe kumatshini wokugqobhoza. Ngexesha lokugqobhoza, umbhobho ujikeleza rhoqo kwaye uhambela phambili, kwaye phantsi kwesenzo se-rolling mill kunye nomphezulu, umgodi uyakheka kancinci kancinci ngaphakathi kombhobho owonakeleyo, obizwa ngokuba yi-capillary tube. Emva koko ithunyelwa kumatshini wokuqengqa umbhobho ozenzekelayo ukuze iqengqeleke ngakumbi, kwaye ubukhulu bodonga bulungiswa ngokulinganayo kumatshini wonke. Umatshini wokulinganisa usetyenziselwa ubungakanani ukuze kuhlangatyezwane neemfuno ezisemgangathweni. Ukusetyenziswa komatshini wokuqengqa oqhubekayo ukuvelisa imibhobho engenamthungo ye-ASTM A106 eshushu yindlela ephucukileyo. Imibhobho engenamthungo ye-ASTM A106 inezicelo ezininzi, ezisetyenziswa kakhulu njengemibhobho okanye izinto zokwakha ukuthutha ulwelo. Ezi nkqubo zimbini zahlukile ngokubhekiselele ekuchanekeni, umgangatho womphezulu, ubungakanani obuncinci, iimpawu zoomatshini, kunye nesakhiwo esincinci.
Ukusebenza koomatshini

Umbhobho wentsimbi engenamthungo we-ASTM A106Gr.B yintsimbi esetyenziswa kakhulu enekhabhoni ephantsi, esetyenziswa kakhulu kumashishini epetroleum, amachiza kunye nebhoyila. Le nto ineempawu ezintle zoomatshini. Umbhobho wentsimbi we-A106-B ulingana nombhobho wentsimbi engenamthungo wentsimbi welizwe lam we-20, kwaye usebenzisa umgangatho wepayipi yentsimbi engenamthungo ye-ASTM A106/A106M yobushushu obuphezulu, ibakala B. Ingabonakala kwimigangatho yepayipi yezityalo zeekhemikhali ze-ASME B31.3 kunye nombhobho wokucoca ioyile: Uluhlu lobushushu bokusetyenziswa kwezinto ze-A106: -28.9~565℃.
Umbhobho wentsimbi engenamthungo oqhelekileyo we-ASTM A53, ofanelekileyo kwiinkqubo zoxinzelelo lwemibhobho, imibhobho yemibhobho kunye nemibhobho yenjongo ngokubanzi enamaqondo obushushu angaphantsi kwama-350°C.
Umbhobho wentsimbi ongenamthungo i-ASTM A106 yokusebenza kubushushu obuphezulu, ifanelekile kubushushu obuphezulu. Ihambelana nombhobho wentsimbi osemgangathweni kazwelonke weNombolo 20.
I-ASTM ngumgangatho we-American Materials Association, owahlukileyo kwindlela yokwahlulahlula yasekhaya, ngoko ke akukho mgangatho ungqongqo ohambelanayo. Kukho iinkcukacha ezininzi ezahlukeneyo zeemveliso phantsi komzekelo ofanayo, kuxhomekeke kwindlela oyisebenzisa ngayo.
