Two test piece geometries are described, including a dumbbell and a ring test piece. Fatemi, published in the International Journal of Fatigue 24 2002 , pp. The oil and gas sector is finding significant use for lightweight, high strength thermoplastics and thermoset composite materials to replace their heavy metal counterparts in rig construction and onboard devices. The two widely used fatigue life parameters are 'maximum principal strain' and 'strain-energy density. The expert team helps clients predict, manage and improve the performance of critical polymer-based infrastructure, components and materials. Is your company fully prepared for 2014 and beyond?.
This is particularly required for fatigue tests in fluid environments. Real-time last sale data for U. Where elastomers may have served in the past, thermoplastics will be required in the future; where thermoplastics may not meet all demanding conditions, ap. They offer excellent levels of resistance aggressive chemicals and can cope with higher temperatures than most bulk lining polymers. Primary research involved interviews with key industry contacts across global locations, and was supplemented by information extracted from company websites, trade journals and conference proceedings. In addition, mixing quality will influence the number and size of defects voids, carbon black agglomerations, etc.
Technical Publications Renowned technical publisher Smithers Rapra produces a wide range books and a polymer database covering all aspects of rubbers, plastics and polymer-based composite materials. The pipe assembly is maintained at constant pressure and a bending load applied using an actuator to supply a cyclic lateral load or strain between two points. This can result in the test piece buckling if the test piece is forced to return to its original starting position. Houston is the ideal place for the global audience of oil and gas professionals. The sphere of fibre rope expertise has witnessed amazing swap and technological boost over the past few many years. Frequently this involves consultative support with failure diagnosis or materials selection. The auditors we employ undergo hundreds of additional hours of accredited training, and an intensive competency program, which ensures our clients receive the absolute best in value and service.
One of the principle advantages high performance polymers provide for oil and gas applications are their corrosion resistance. View source version on businesswire. In the heart of the energy corridor, it is both easily accessible to locals and perfect for after conference business meetings for travelling attendees. The requirements may be resistance to specific chemicals or to abrasion. This might be salt water, oil, drilling mud, chemicals, potable water and sewage. With this test arrangement, it is relatively straightforward to plot stress or strain versus number of cycles to failure S-N curves with multiple data points at each test temperature. As the industry is forced to go deeper, so the occurrence of major corrosion problems to steel pipes and other metallic components increases.
DuPont de Nemours and Co. In polymers, the potential energy released from the surrounding material is spent on both reversible and irreversible changes to create the new surfaces. Where elastomers may have served in the past, thermoplastics will be required in the future; where thermoplastics may not meet all demanding conditions, ap. Fractography offers an perception into harm mechanisms and underpins the improvement of bodily dependent failure standards. Tanks linings are very specific to the medium being stored. However, Smithers Rapra still has the capability to undertake these tests, if required. The polymer industry is trying to increase the lifetime of the assets associated with recovery, production and processing by providing corrosion resistant materials.
High Performance Polymers for Oil and Gas 2013. The latter has been a productive source of business for several polymers sectors. The online workshop will outline how test procedures are open to some interpretation, and why published results can sometimes be incomplete or inconclusive. The advantages of metals, like steel, are well known, as are their drawbacks. Product tests An alternative to carrying out material tests on standard test specimens is to perform cyclic tests on the products or components themselves. Linings and coatings In an industry that is schooled in the tradition of steel products, one major contribution that the polymer industry is making is in the area of corrosion-resistant coatings.
Several high performance polymers are used for coatings but only in low market volumes. With increasing demands for increasing performance of plastics and elastomers in the oil and gas industries, where temperatures are increasing and chemical environments are becoming more aggressive, it is desirable to be able to produce long term predictive fatigue data that are more representative of these operating conditions. Along with fierce competition, that includes battles for lower oil prices, organizations that want to succeed in this market are required to continually improve in order to prosper. This aligns with the wider petrochemical industry focus on increasing the lifetime of assets associated with recovery, production and processing by providing corrosion-resistant materials. Secondary research was based on a literature review of the market and company reports in addition to magazine and journal abstracts. Cooper, Smithers Rapra, Proceedings of High Performance Elastomers and Polymers for Oil and Gas Applications, April 17-18, 2012. Advances in drilling techniques are opening up massive new potential in shale gas reserves.
On Wednesday, March 9, 2016, Smithers Rapra and Victrex will together host a free webinar looking at the standard test methods for assessing high-performance polymers and in particular, polyaryletherketones in hot and sour oil and gas environments. Comments For most standards, there is a comment in the scope that no exact correlation between the test results and service life is given or implied. Polymer Specialists for the Oil and Gas Recovery Industry Smithers provides for clients working in the oil and gas recovery industry. Industry estimates suggest that at least 80% of oil and gas industry products are still metallic and that the impetus for change is sluggish, despite the growing awareness of corrosion resistant alternatives. Smithers Rapra has a modular approach to rig building; existing load cells, linear actuators, conditioning chambers, etc.
About Smithers Rapra Smithers Rapra is the global leader in rubber, plastics, polymer and composites testing, consulting and information products and events, with key focuses including the tire, industrial, transportation, consumer and medical industries. Depending on the complexity and duration of the test, it may be more cost-effective to build a product test rig. Land dependent operations are using a broader array of more advantageous oil restoration fluids and media, in addition to being compelled to paintings in excessive H2S focus deposits, each one of which locations additional pressure at the non-metallic elements of the units and instruments utilized in the restoration of fluids and gases. The Future of High Performance Polymers for Oil and Gas to 2020 is based on in-house primary research- supported by extensive industry data. Alternatively, corrosion resistant alloys can be specified, but these are often more expensive than lining a carbon steel product with a corrosion resistant polymer. Where materials fatigue data are required, the equipment listed in the following sections is routinely used due to the flexibility of test parameters.
The test equipment for the ring test piece is shown in figure 3. Most academic studies with this kind of arrangement concentrate on transparent, brittle materials such as polystyrene and poly-methyl methacrylate, where it is relatively easy to observe crack propagation and linear elastic behavior. According to the report there are in the region of 950,000 oil wells in production across the globe, each with ongoing needs for new and replacement parts. The literature review suggests that the use of uniaxial tensile fatigue and energy release rate has limited value for these applications. Some prominent speakers include Sebastien Viale, Dr. Secondary research was based on a literature review of the market and company reports in addition to magazine and journal abstracts.
