The combination of epoxy and phenolic formulations provides the superior molecular interlinkage, and also the same bend resistance and torque resistance as metal. The internal coating for casing and tubing is suitable for extremely corrosive or high temperature environment, such as chemical treatment wells, high temperature and high pressure corrosive wells. What\u2019s more, it can provide the capability of resistance to scale, pitch and paraffin so as to promote flow efficiency.<\/span><\/p>\n<p><span style=\"color: #000000;\"><strong>Product
