Product Description

Impulse nitriding-in-vacuum anticorrosion tubings and sucker rods researched and developed by our company are the newest products instead of coated tubings , auto catalysis nickel-phosphor alloy electrodeposition anticorrosion tubings used nowadays . It is a vacuum chemical heat treating technology , resolved the problem of corrosion resistance in material cover , and formed a fine and even anticorrosion bright cover , so that its anticorrosion is higher **8 times than that of tubings treated by conventional crafts , and made the tubings cover have better abrasion resistance , corrosion resistance and high temperature resistance than the body material , and can adapt to any bad geologic environment . It resolved three problems of tubings corrosion , thread gluing and eccentric wear , filled the country blank space , gained two country patents , and reached the leading position in technology .
