Ha nako ea selemo le selemo ea ho futhumatsa e ntse e atamela, NSEN e tla kena mokhahlelong o maphathaphathe hlabula. Ha re itokisetsa nako ea selemo ea ho futhumatsa, bareki ba rona ba behile liodara tse 'maloa ka tatellano. Ho lebeletsoe hore li-valve tse 800 tsa serurubele bakeng sa ho futhumatsa li tla hlahisoa selemong sena. Ka hona, k'hamphani ea rona e na le li-welding tse ngata tsa butt, le flange butterfly valve casting.

Ka tlase re tla hlahisa ka bokhutšoanyane li-valve tsa serurubele tse sebelisetsoang ho futhumatsa setereke;
