TP316L / TP304 / TP321 / TP347 Cold Drawn Sanitray Tube Seamless In
Instrument Industry
Bright annealed sanitary tube has very clean inner surface . MTSCO
has our own high technology , when tubes have been produced they
already have cleaned inner surface , even though we haven’t cleaned
them . Of cause , we’ll do clean later . So when we finished clean
process , the tubes are totally clean enough !
MTSCO tubes can be used in General service industries ( petroleum ,
food , chemical , paper , fertilizer , fabric , aviation and
nuclear ) , fuild & gas & oil transport industries , pressure and
heat transmission industries , construction and ornament industries
, boiler and heat exchangers industries , decorative usage ( road
lamp facilities , bridge handrail , expressway railing , bus stop ,
airport and gymnasium ) etc .
