Umgangatho wemibhobho yemizi-mveliso yokuchasana nomhlwa, umaleko wokugquma ubushushu kunye nomaleko ongangeni manzi
Umgangatho wemibhobho yolwaleko oluchasene nomhlwa, umaleko wokugquma ubushushu kunye nomaleko ongangeni manzi Yonke imibhobho yemizi-mveliso yesinyithi ifuna unyango lokuchasana nomhlwa, kunye neentlobo ezahlukeneyo zemibhobho zifuna iintlobo ezahlukeneyo zonyango lokuchasa umhlwa. Eyona ndlela ixhaphakileyo yonyango lokunqanda umhlwa ...Funda ngokugqithisileyo -
Iingxaki zobushushu ekuveliseni imibhobho yentsimbi yomthungo ethe tye
Kwinkqubo yokuvelisa imibhobho yentsimbi yomthungo othe tye, iqondo lokushisa kufuneka lilawulwe ngokungqongqo, ukwenzela ukuba kuqinisekiswe ukuthembeka kwe-welding. Ukuba iqondo lokushisa liphantsi kakhulu, kunokubangela ukuba indawo ye-welding ayikwazi ukufikelela kwiqondo lokushisa elifunekayo kwi-welding. Kwimeko apho uninzi lwam...Funda ngokugqithisileyo -
Iingxaki zokuthambisa ekuveliseni imibhobho yentsimbi yomthungo othe tye
Imibhobho yentsimbi yomthungo ethe tye kufuneka isebenzise imveliso ukuze ihambelane nenkqubo yokuvelisa, oko kukuthi, i-lubricant yeglasi, eyaveliswa ngegraphite ngaphambi kokusebenzisa i-lubricant yeglasi, kuba ngelo xesha kwakungekho mveliso injalo kwiimarike. Ke ngoko, igraphite ingasetyenziswa kuphela njenge-lubricant, kodwa ...Funda ngokugqithisileyo -
Ulungelelwaniso kunye noLawulo lweNdawo yokuNyelwa okuPhakamileyo kweLuphu yeThubhu yentsimbi yomthungo
Umthungo othe ngqo we-tube ye-tube evuselela i-frequency ngokuphambeneyo kwi-square root of capacitance kunye ne-inductance kwi-excitation circuit, okanye i-proportional kwi-square root of voltage kunye ne-current. Logama nje i-capacitance, i-inductance okanye i-voltage kunye nekhoyo kwi-loop itshintshiwe, i...Funda ngokugqithisileyo -
Izinto ezichaphazela ukuchaneka kunye nesisombululo sokufunyanwa kodonga lwe-oyile ye-oyile
Umgangatho we-API umisela ukuba umgangatho wangaphakathi kunye wangaphandle we-petroleum casings evela kumazwe angaphandle nangaphandle kufuneka ingasongwa, ihlulwe, iqhekezwe okanye ikhutshwe, kwaye ezi ziphene kufuneka zisuswe ngokupheleleyo. Isingxobo sepetroleum kufuneka sigqunywe ngokupheleleyo ukuze kubonwe ubukhulu bodonga oluzenzekelayo. Ngoku...Funda ngokugqithisileyo -
Ukulungiswa ngaphambi kokufaka umbhobho wensimbi we-3PE we-anti-corrosive
Ngaphambi kokufaka ipayipi yensimbi ye-3PE ye-anti-corrosion, kufuneka uhlambulule indawo engqongileyo kuqala, kwaye uqhube iimvavanyo zobugcisa kubalawuli kunye nabaqhubi bemishini abathatha inxaxheba kumsebenzi wokucoca. Ubuncinci umgca omnye wabasebenzi bokhuselo kufuneka uthathe inxaxheba kumsebenzi wokucoca. Into mna...Funda ngokugqithisileyo
