Product Features

1. Excellent surface finish on both inner and outer surfaces;

2. Upon completion of production, the steel pipes exhibit no oxide scale, scratches,

gouges, or other defects on either inner or outer surfaces;

3. During expansion, contraction, flattening, and bending operations,

 the steel pipes show no cracks, and remain dimensionally stable after cold bending,

while capable of withstanding medium to high pressure;

4. Superior performance, enabling various complex deformations and advanced mechanical

processing treatments.
