1 / 2 Inch Sch80s ASTM A269 Bright Annealed Stainless Steel
Sanitary Tube
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 !
