Size range from OD3.2~76.2mm (1/8 – 3 in.), WT as per customer’s requirement
Top quality products
Applications:
For heat-exchanger and condenser, heat supply, heat transfer equipment. Petro-chemical industry, transportation of fluids, low and medium pressure boiler, etc.
Competitive Advantage:
With very good surface quality(very few oxide skin), A179 is one of our most popular products. We exported this material to many countries about 7,500MT/Year, most of the customers have been cooperated with us for more than 6 years. Good & stable quality with the best service helped us to set up very good long-term relationships with our customers.
Advanced equipment, serious attitude to quality control makes us keep our qulity stable and good.
