10 Inch 3000psi Steel Reinforced RTP Line For Flexible Onshore Pipe SRTP complied with the provisions of API 15S, uses the high strength steel cord fabricated tape to be the reinforcement. The SRTP pipe offers high pressure resistance and it is flexible for coiling into spool. It is less cost than expensive none metal fibers like Kevlar and Carbon, and has better temperature against characterizes compared with glass fiber. With Goldstone enhanced anti corrosion liner tube design, high strength SRTP pipe could be a kind of valuable pipeline for some particular applications for onshore transportation and one of the better option for bigger diameter RTP pipeline. Goldstone can supply the high qualified steel cord tape for RTP manufacturers. The high strength steel cord is made by twisting numbers of fine steel wire, which has very good flexibility and high monofilament strength. The unit tensile strength of steel cord is greater than 3000 MPa, which performance is higher than 800MPa of the impregnated glass fiber tape. For example, the 1.0mm steel cord tensile strength is about 1900-2000N, it is almost same as 900 tex aramid fiber, but 1600 tex (about 1.1mm) glass fiber or polyester fiber can provide 800-900N strength only. Therefore, steel cord could replace the expensive synthetic fibers as economic reinforcement material used on large diameter composite pipe.
