BFe30-1-1 Corrosion Resistance Petong Tube For Sea Water Heat Exchanger
1. Description
BFe30-1-1 iron Petong tube is a copper nickel alloy tube with good mechanical properties, high corrosion resistance in seawater, fresh water and steam, but poor machinability. BFe30-1-1 iron Petong tube is used for condensers and thermostats working at high temperature, high pressure, high speed in shipbuilding industry.
BFe30-1-1 alloy steel with high strength and good chemical stability at high temperature. It includes oxidation resistant steel and hot strength steel. Oxidation resistant steels generally require good chemical stability, but bear lower load. Heat resistant steel is often used in the manufacture of boiler, steam turbine, power machinery, industrial furnace, aviation, petrochemical and other industrial sectors working under high temperature. In addition to high temperature strength and high temperature oxidation corrosion resistance, these parts also require enough toughness, good machinability and weldability, and certain structural stability according to different applications.
The company's copper tube grades mainly include BFe10-1-1, BFe30-1-1, HSn70-1, HSn70-1B, HSn70-1AB, HAl77-2, H68A copper tube, fin tube and U-tube. The products are produced in strict accordance with the standard, and the finished products can be tested by the third party according to the customer's requirements. These copper tubes are mainly used in power plants, desalination, petrochemical, mechanical ships and automotive 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, well received by customers.
