We recommend the use of spray welding polished rods for our Southeast Asian customer based on their oil well wear condition and sand content of polished rods. The spray welding polished rod covers the surface of the polished rod with alloy powder by spray welding, which increases the hardness of the polished rod surface, improves the wear resistance and corrosion resistance of the polished rod, and is very suitable for sand wells and corrosive oil wells. This kind of polished rod has been exported to many countries all the year round, and has a good effect. Southeast Asian customer has decided to order 120 pieces of 1-1/2" and 1-1/4" specifications after evaluating our spray-welding products and combining their own well conditions.
