Xa kufikwa kulwakhiwo kunye nobunjineli boburhulumente, ukhetho lwezinto ezibonakalayo lubalulekile ekuqinisekiseni ukuthembeka kunye nobomi obude besakhiwo. Esona sixhobo sifumene igama eliqinileyo kwishishiniI-ASTM A252 Ibanga 2I-Pipers. Le bhlog iyakusebenza kwinkcazo, iipropathi, kunye neemfuno zokumakisha kwe-ASTM A252 IBakala 2 ukufumana ukuqonda okubanzi kweprojekthi yakhe.
Yintoni i-ASTM A252 Ibanga 2?
I-ASTM A252 yinkcazo esemgangathweni ye-weldid kunye ne-tubular yentsimbi engenamthungo yezicelo zesiseko. IBanga lesi-2 yenye yamabakala amathathu acacisiweyo kulo mgangatho, kunye neBanga loku-1 olona nqanaba liphantsi neliBanga lesi-3 liphezulu ngokwemigaqo yokuvelisa amandla. I-ASTM A252 IBakala 2 le-2 ye-Tubular yenzelwe ukulungiselela ibhalansi yamandla kunye nokubenza bazilungele iintlobo ngeentlobo zezicelo, kuquka neziseko ezinzulu, izakhiwo zaselwandle, kunye nezinye iimeko ezithathwa ngumthwalo.
Iipropathi eziphambili ze-ASTM A252 Ibanga lesi-2 zibandakanya amandla obusi esivumo ezingama-350 kwi-PSI kunye namandla anencasa amancinci angama-60,000 psi. Ezi ndawo ziqinisekise ukuba iiplanga zingakwazi ukumelana nemithwalo ebalulekileyo kunye noxinzelelo, zenza ukuba zilungele ukusetyenziswa kwiindawo ezinomngeni.
I-ASTM A252 IBakala 2 le-Pipes Pipes I-Pipes
Inkalo ebaluleke kakhulu ye-ASTM A252 yeBanga le-2 yeBanga le-2 yimfuno yokumakisha ngokufanelekileyo. Imfumba nganye kufuneka iphawulwe ngokucacileyo ukuba ibonelele ngolwazi olufanelekileyo malunga nemveliso. Oku kuphawula kubalulekile ekutyeleni, ukuqinisekiswa komgangatho, kunye nokuthobela imigangatho yeshishini. Ezi nkcukacha zilandelayo kufuneka zibandakanywe kwimakisha:
I-1.Maymeremer Name okanye uphawu: Oku kuchonga umenzi wemfumba, ukuqinisekisa ukuba umsebenzisi angalandela imveliso ibuyele kumthombo wayo.
Inombolo ye-2.Heat: Inombolo yobushushu yisazisi esahlukileyo eyabelwe iqela elithile lentsimbi. Ivumela imvelaphi kunye neempawu zezinto eziza kulandelwa, ezibaluleke kakhulu kulawulo lomgangatho.
3. I-MEGMERTERRE YENKQUBO: Oku kubonisa indlela esetyenzisiweyo ukuvelisa imfumba, nokuba ityhidiwe okanye ingenamthungo. Ukuqonda inkqubo yemveliso inceda ekuvavanyeni iimpawu zentsebenzo zemfumba.
I-Funeral Joint yodidi oluDibeneyo: uhlobo lwe-spiral joral esetyenziswe kwiimfumba yombhobhokufuneka iphawulwe, ukuba iyasebenza. Olu lwazi lubalulekile ekuqondeni ingqibelelo yemfumba.
5. Ububanzi be-Outer: Ububanzi be-pile yemfumba kufuneka buphawulwe ngokucacileyo njengoko buyindawo engqongqo yokufakelwa kunye nokubala.
Ubungqingqwa bomhlaba onobubanzi be-doll yemfumba yenye imilinganiselo ebalulekileyo echaphazela amandla kunye nokukhathazeka.
7. Ulength kwaye ubunzima bomde kubude be: Ubude bebonke bungaphezulu kobude bemfumba kufuneka buchazwe. Olu lwazi lubalulekile kubaqeshi kunye nocwangciso lokufaka.
IGama leSpecialtion kunye neBanga: Okokugqibela, ukumakisha kufuneka kubandakanya igama elichaziweyo (i-ASTM A252) kunye neBanga (iBakala 2) ukuqinisekisa ukuthotyelwa kwemigangatho yemigangatho.
Ukuququmbela
I-ASTM A252 IBakala 2 ye-Piep 2 yinxalenye ebalulekileyo yokwakhiwa kwale mihla, ukubonelela ngamandla ayimfuneko kunye nokuqina kwezicelo ezahlukeneyo. Ukuqonda okubhalwe phantsi kunye neemfuno zokumakisha kubalulekile kubanjineli, iikontraki, kunye nabaphathi beeprojekthi ukuqinisekisa ukuba basebenzisa izixhobo ezichanekileyo kwiiprojekthi zabo. Ngokulandela le migangatho, ishishini lokwakha linokugcina iindlela ezisemgangathweni kwaye ziqinisekise ukhuseleko kunye nobomi obude bobume bolwakhiwo kwala malungu asesiseko.
