| 摘要 |
The present invention is directed to an extrudable resin composition and a method of extruding the extrudable resin composition, comprising a high temperature engineering thermoplastic, one or more reinforcement components, an enhancing filler component, a polymeric lubricant, and an external lubricant, wherein the extrudable resin composition is capable of withstanding temperatures up to about 427° C. The invention is further directed to the use of the extruded pipes and/or lined pipes, produced according to the present method, in downhole tubular applications in oil and gas production; in line pipe, flow line, and transportation line applications in oil and gas production and supply operations; or in most any application where corrosive protection is required to transmit or store corrosive fluids, particularly at high temperatures.
