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...
With the swift progress of electronics industry, discarded circuit boards have become an important source non-degradable waste. In this work, epoxy resin was collected as a precursor to prepare activated carbon (AC) through stepwise carbonization/activation methods. The rough materials with certain graphite and amorphous structure reveal multiple oxygen-containing groups on their surface. process studying adsorption methyl orange by carbon, it is found that in accordance quasi-secondary...
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 three-phase separator was perforated after four years' service. perforation position is at the bottom of vessel under baffle plate in an oil transfer station. cause investigated by chemical analysis using a direct-reading spectrometer, microstructure examined optical microscope (OM), and lab simulated corrosion experiments electrochemical workstation, products with scanning electron microscopy (SEM), energy dispersive spectrometer (EDS) this paper. analyses indicated that coating base...
Abstract Excellent flame resistance is supposed to be taken into consideration for electronic packaging materials due the spontaneous combustion of short circuits, except good mechanical and dielectric properties. Herein, a hyperbranched polyborosiloxane (HPSiB) retardant was synthesized via simple one‐pot transesterification as multifunctional additive cyanate ester (CE) resin. The HPSiB with many active terminals features compatibility resin matrix, while catalyzing curing reaction that...
Nano-ZnO particles were deposited on the surface of silver nanowires (AgNWs) by precipitation method, and obtained AgNW@ZnO filler with core-shell structure was added to epoxy resin prepare AgNW@ZnO/EP thermally conductive composites. The ZnO coating AgNWs effectively improves thermal conductivity When 8 wt% resin, composite increased 0.77 W/(m·K). enhancement is attributed fact that interface bonding between matrix, thus strengthening contact AgNWs. In addition, electrical insulation...
Flexible composite pipes are advantageous in ultra high strength, modulus, pH and corrosion resistance light weight, but there still some hidden safety troubles because they poorer thermostable capacity. Therefore, test samples of flexible were prepared with high-temperature polythene (PE-RT) as the neck bush aramid fiber reinforcement layer. Experimental study was conducted by using HPHT vessel differential thermal scanner for different working conditions, temperatures, whole-pipe...
Abstract The chapter deals with the performance evaluation of polyethylene raised temperature resistance (PE-RT) and (PE) using autoclave test under sour oil gas medium conditions. analyses changes showed that PE-RT has good media at 60°C. As increases, its mechanical properties decrease, accompanied by an increase in weight. Comparative no matter what conditions are, is better than PE80. depends on higher degree branching. Short branches are distributed between crystals to form a connection...
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...
In the process of transporting oil and gas, service performance thermoplastic pipes will decline due to multiple influences medium, temperature, pressure. order study changes PVDF under gas transportation conditions, high-temperature autoclave is used simulate state pipe in mediums. The samples are exposed simulated mediums for 1 week, 3 weeks, 5 7 weeks 60 °C 90 conditions. After exposure test, physical chemical properties tested compared with initial samples. Compared sample, sample...
Spoolable reinforced plastic line pipes (RTPs), exhibiting a series of advantages such as good flexibility, few joints, long single length, light weight, easy installation, etc., have been widely used in the onshore oil and gas industry gathering transportation, high pressure alcohol injection, water sewage treatment, other fields. However, due to lack clear standard specificationof limit operating properties for RTPs, three typical failure modes, i.e., tensile, flexure, torsion, frequently...
