NBK Condition Phosphating tube
Our raw material are high quality low carbonsteel. After pickling, cold-drawn, no oxidization heat treatment( NKB Status),nondestructive testing, the wall honing and inside flushing under high pressure,antirust oiling inside and outside surface then sealed with plastic caps on bothends.
Our steel tubes are in high precision, goodbrightness and no oxidize residual substance in inner and outer surface andcould withstand high pressure, no deformation after cold bending, no crack andbreak after flattening and flaring, with good mechanical property and nodeformaion after bending at any angle.
Our steel tubes are widely used in hydraulicsystem, automobile and other occasion which with the high requirement of theprecision, brightness, cleanness and mechanical properties.
