BFe30-1-1 Corrosion Resistance Pektong Tube For Sea Water Heat Exchanger
1. Description
BFe30-1-1 iron white copper (pektong pipe) is a kind of pipe with poor processability and corrosion resistance to seawater, fresh water and steam.
BFe30-1-1 iron white copper tube is a kind of copper nickel alloy pipe with good mechanical properties. Although it has high corrosion resistance, its machinability is poor. BFe30-1-1 iron white copper tube is used in high temperature, high pressure and high speed condenser and thermostat in shipbuilding industry.
The company's copper pipe grades mainly include BFe10-1-1, BFe30-1-1, HSn70-1, hsn70-1b, hsn70-1ab, HAl77-2, H68A copper tube, finned tube and U-tube. The product is produced strictly according to the standard. The finished product is smooth and straight without burr. The composition and performance of the product fully meet the international standard. In addition, it can also be tested by a third party according to customer requirements. These copper tubes are mainly used in power plants, seawater desalination, petrochemical, mechanical ships and automobile heat exchangers. We have rich production experience, professional technology, excellent equipment, superior quality, reasonable price, high quality service, so that our products sell well all over the world and are well received by customers.
