1. Ishubhu yesikwele esishiselwe iyishubhu yensimbi eyisikwele engenalutho, eyaziwa nangokuthi insimbi engenalutho eyakhiwe ngendlela ebandayo. Yakhiwa ngokugoba okubandayo kanye ne-welding ephezulu emva komugqa ogoqekayo noma obandayo noma ikhoyili njengensimbi Emise okwesikwele enomumo oyisikwele oyisikwele nosayizi.
Ngaphezu kokuqina kodonga lweshubhu lesikwele esinodonga oluwugqinsi, ubukhulu bekhona kanye nokuqina komphetho kufinyelela noma kudlule izinga lokumelana elishiselwe ishubhu lesikwele elakheke ngokubanda. Usayizi we-engeli engu-R ngokuvamile uphakathi kwezikhathi ezi-2 nezingu-3 ukujiya kodonga. .Ngokwezidingo zamakhasimende, singakwazi futhi ukukhiqiza amashubhu ayisikwele e-R-angle anosayizi odingwa amakhasimende;
2. Ishubhu yesikwele Ishubhu yesikwele engenamthungo iwumucu omude wensimbi onengxenye engenalutho futhi awekho amalunga endaweni ezungezile. Ishubhu eliyisikwele elakhiwe ngokukhipha ishubhu elingenamthungo ezinhlangothini ezi-4 zesikhunta. Ishubhu yesikwele inengxenye engenalutho futhi isetshenziswa ngobuningi. Isetshenziswa ekuthuthweni kwe-liquid, ukusekelwa kwe-hydraulic, ukwakheka kwemishini, ingcindezi ephakathi nendawo nephansi, ishubhu elinomfutho ophakeme we-boiler, ishubhu yokushintshanisa ukushisa, igesi, i-petroleum nezinye izimboni. Inamandla kune-welded futhi ngeke iqhekeke.
