coated steel pipe

coated steel pipe:
1.High-performance
2.With competitive prices
3.The results of better effectcoated steel pipe
Oxygen lance for refractory is a new energy-saving product and based on oxygen blowing directly through steel tube. Oxygen lance for refractory is used for electric furnace, Oxygen flux for electric furnace, decarburization and stir. It can reduce the production cost and improve the melting quantity, to keep good thermal stability.
Character: High refractoriness of the products, steel tube and refractory coating with strong adhesive force, smooth surface, bending of 6 meters to allow / 90 °, not crack and peeling off. It can improve the operating rate of 5-10%.Its better than similar metal in side of reducing the production cost, saving the steel tube 40-50% and labor intensity.
