Shenhai Explosion-Ubungqina
Izibane ezikhusela uqhushumbo azinyanzelekanga ukuba zingangenwa manzi.
Umgaqo wokungatshi (evalelweyo) izibane ezingagqabhukiyo kukwahlula umthombo wokutshisa kwiigesi eziqhumayo. Izingxobo zazo azitywinwanga ngokupheleleyo kwaye zinezithuba ezincinci. Ezi zikhewu zidlala indima ebalulekileyo ekuthinteleni ugqabhuko-dubulo; njenge ilangatye idlula kwezi zithuba zimxinwa, idibana nokuchasa kunye nokutshatyalaliswa kobushushu, ukunciphisa ubushushu ukuya kumaqondo angonelanga ukutshisa iziqhushumbisi. Kwiimfuno ezifuna zombini ubungqina bokudubula kunye into evikela amanzi izakhono, qinisekisa ukuba umgangatho wokhuseleko we-casing uchazwe njenge-IP65 okanye i-IP66.
