Spiral Welded Pipe For Fire Fighting Piping
Re motlotlo ho hlahisa maemo a rona a holimo-limospiral seam welded pipeline, ka ho khetheha e etselitsoeng phala ea mohala le phala ea mollo ka likopo tse kholo tsa bophara.Liphaephe tsa rona tsa spiral seam welded ke tharollo e phethahetseng bakeng sa liindasteri tse hlokang liphaephe tse tšoarellang le tse tšepahalang.Ka theknoloji e tsoetseng pele ea tlhahiso le lisebelisoa tsa boleng bo holimo, liphaephe tsa rona tsa spiral seam welded li kopana ebile li feta maemo a indasteri.
Spiral seam welded pipe e bua ka phala ea tšepe e nang le seam e spiral e kentsoeng ka mokhoa oa ho tjheseletsa arc.Mokhoa ona o tiisa weld e matla le e tsitsitseng ka bolelele ba phala, e fana ka matla a phahameng le ho tšoarella.Liphaephe tsa rona tsa spiral seam welded pipe li etselitsoe ho mamella maemo a thata a litlhoko tsa kopo, ho li etsa hore e be tse loketseng liindasteri tse fapaneng.
