Abstract

The pipelines endure a massive amount of torsion in the reeling process and installation. The pipe may face torque in two directions, clockwise and anticlockwise while the torsional behaviour of the pipeline has a strong asymmetry due to its helically-wrapped layers. Investigating the mechanical behaviour of steel strips reinforced thermoplastic pipe (SSRTP) subjected to both twist angles is hence important for engineering applications. A comprehensive numerical model is established to determine all failure modes of SSRTP under torsion. Compared with a newly presented theory, the torsion stiffness obtained from the numerical model is verified. Experimental tests are employed for a better understanding of the SSRTP's practical response against torsion. The similarities and differences in the behaviour of SSRTP under both positive and negative torsional angles are pointed out. The effect of friction on the pipe's mechanical behaviour is analyzed comprehensively and related recommendations are proposed. Besides, a parametric study is carried out to obtain the characteristics that most significantly affect the torsional behaviour of pipe.

期刊介绍： Pressure vessel engineering technology is of importance in many branches of industry. This journal publishes the latest research results and related information on all its associated aspects, with particular emphasis on the structural integrity assessment, maintenance and life extension of pressurised process engineering plants. The anticipated coverage of the International Journal of Pressure Vessels and Piping ranges from simple mass-produced pressure vessels to large custom-built vessels and tanks. Pressure vessels technology is a developing field, and contributions on the following topics will therefore be welcome: • Pressure vessel engineering • Structural integrity assessment • Design methods • Codes and standards • Fabrication and welding • Materials properties requirements • Inspection and quality management • Maintenance and life extension • Ageing and environmental effects • Life management Of particular importance are papers covering aspects of significant practical application which could lead to major improvements in economy, reliability and useful life. While most accepted papers represent the results of original applied research, critical reviews of topical interest by world-leading experts will also appear from time to time. International Journal of Pressure Vessels and Piping is indispensable reading for engineering professionals involved in the energy, petrochemicals, process plant, transport, aerospace and related industries; for manufacturers of pressure vessels and ancillary equipment; and for academics pursuing research in these areas.
