Reinforced thermoplastic composite pipes (RTPs) have been widely used for oil and gas gathering transportation. Polyvinylidene fluoride (PVDF) has the greatest potential as a liner of RTPs due to its excellent thermal mechanical properties. However, permeation gases is inevitable in liner, which may lead blister failure damage safe operation RTPs. In order clarify behavior obtain mechanism mixture (CH4/CO2/H2S) PVDF at normal service conditions, molecular simulations were carried out by...
This research aimed to provide an understanding of the selection and safe application pipeline liner materials for hydrogen transport by examining permeation properties mechanisms within polymers commonly used this purpose, such as high-density polyethylene (HDPE) ethylene-vinyl alcohol copolymer (EVOH), through molecular simulation. The study was carried out defined operational parameters temperature (ranging from room 80 °C) pressure (from 2.5 10 MPa) that are pertinent infrastructures....
The liner of reinforced thermoplastic composite pipes (RTPs) used for oil and gas gathering transportation experienced blister failure due to permeation. Few reports have appeared on the problem permeation in thermoplastics with absorbed crude oil. Accordingly, permeability CH4 polyvinylidene fluoride (PVDF) containing was studied at normal service conditions by molecular simulations. results showed that solubility coefficients PVDF were much lower than those pure PVDF. It can be concluded...
