8 INCH 3000PSI OIL&GAS RTP PIPE PRODUCTION LINE
Pipe Introduction
Goldstone developes its unique tape wrapping technology to manufacture high pressure 8 inch 3000psi oil&gas RTP pipe. The tapes could be high strength steel cord tape
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.
High Strength Steel Cord
It is made of qualified high carbon steel with surface coating, drawing, twisting and other processes. The steel cord is one of the main framework materials of car tire. Steel cord is classed from normal strength (NT) to high strength (HT), and super high strength (ST) and ultra high strength (UT). We normally select HT and ST for RTP pipe.
Features: High tensile strength up to 3500N. The steel cord is made of multi strands of fine steel wire with excellent softness after surface treatment, the anti-corrosion performance of the steel is significantly improved.
Through the tape making machine and technology developed by Goldstone, numbers of steel cords are bonded with polyethylene and made into a reinforced tape.
The high-strength steel cord has dia. 0.8-1.5mm, and the pre-made tape thickness is 1.0-2.0 mm. After wound 2-4 layers of steel cord on the pipe then can meet the pressure. The equipment investment is smaller and the process is relatively simple. Under the highe
r temperature, the performance is obviously better than glass fiber tube. Additional, the high elongation of steel allowed the reinforced tube more flexible for coiling.
According to the provisions of API15s for metal reinforced RTP, the design safety factor can be used 0.5. In the practical, the pipe factory usually choice 2.25 times operation pressure as the burst pressure.
