Pipe Design 1）HDPE100 Outer Layer 2）Fiber Reinforced Layer 3）Inner Tube When the non-bonded pipe is subjected to negative pressure or alternating pressure in the operation, the separation between layers may cause pipe failure. Therefore, for large-diameter flexible reinforced composite pipes, the fully bonded reinforcement layer structure is preferred. 1.1 Inner Tube Design (Multiple Layer with Gas Barrier Structure) The core pipe has total four layers structure. 3: Gas permeation barrier. This layer is designed for stop or reduce the gas permeation through the RTP inner tube wall, such...

hydrocarbons can more easily pass through the plastic wall. Long-chain polyamides, often referred to as nylons, are much denser and chemically stable than traditional polypipe.In 2015, polyamide-6 (PA6) and polyamide-12 (PA12) products were developed specifically as liners for gathering pipelines, serving as a barrier between the flowing hydrocarbons and the host pipe. As the updated technology, five layers co-extrusion structure has beendeveloped, and EVOH liner is used to enhance gas penetration protection. 1.2 Material Selection Glass Tape Reinforced RTP Pipe Material Items Inner Tube...

GF RTP/TCP Pipe Specifications Dia. Remark For DN 50 pipe, if we use 850-900 MPa glass fiber tape, can reach 25MPa working pressure. Working Pressure: According to API 15S, glass fiber RTP pipe Safe Factor= 3 Rating pressure =Burst Pressure / F But rating pressure is on temperature < 40 C (104F) If temperature = 65C (149F), then we take safe factor of 4-5. If temperature=82C (180F), then we take safe factor of 5-6. Glass tape: The pipe pressure is calculated by 0.3mm GF tape

Steel SRTP Pipe Specification（Steel Cord） DN Steel Layers Liner Wall Pipe Wall Steel Cord Tape can give high tensile of steel more than 2500 MPa Steel cord dia. 0.8, 1.02, 1.22, 1.38 and 1.50 can be selected, tensile 1600-4000N According to API 15S, Steel Reinforced RTP pipe Safe Factor is 2.0, Rating operation pressure can be calculated by Burst Pressure / 2.25. It is available to use aramid tape instead of steel cord tape. And the thickness of aramid tape is about 1.5-2.0mm, same as steel cord tape. Aramid tape tensile is higher than steel cord tape, so can give high pipe pressure....

Reinforcement Material Steel Cord Tape Steel reinforced SRTP pipe uses the high strength steel cord fabricated tape to be the reinforcement. Steel cord offers higher unit tensile compared with glass fiber and flat steel tape, so it is more efficient to get high pressure in larger diameter pipe. Meanwhile, steel cord is a very soft string, so the finished RTP is more flexible and coiled on spool easily. It is economic than synthetic fibers like Kevlar and Carbon, and has better temperature resistance and elongation than glass fiber. Steel cord reinforced pipe complies the provisions of...

1.4 RTP Pipe Manufacturing Process There are two kinds of RTP manufacturing process, one step or two steps. One step process is suitable for steel wire reinforced pipe machine, steel cord tape pipe and big diameter pipe. Because use less numbers of wrapping machine, so the total length of the production line is limited in 60-80 meters. The benefit of one step process is that there are few process control points, the quality of composite pipe can be checked online, and the length of pipe produced is only limited by the reinforced material loaded on the wrapping machine. Intwo-step process,...
