Manufacturing Process

 

Grade

ㆍAP – Annealed and Pickled Pipe

ㆍMP – Mechanically Polished Pipe

ㆍBA – Bright Annealed Pipe

ㆍEP – ElectroPolished Pipe

 

ASFLOW MATERIALS

ㆍSUS 316L Single melt or SUS 316L Double melt is used to meet the stringent requirements of the semiconductor and aerospace industries.

ㆍOur state-of-the-art Pipe & Tube prevent out gassing and improve corrosion resistance while providing excellent compatibility with speciality gases and chemicals.
