Abstract

The aim of this study is to evaluate the efficiency of a hybrid patch of Jute with/without Glass fiber reinforced with Steel wire for repairing defective API X52 pipeline. Five specimens were tested using Jute fiber, Glass fiber and Steel wire to enhance the mechanical properties according to ASTM 3039 and D790 standards. The experimental results showed that the effects of hybrid materials (synthetic and natural) for repairing API X52 pipeline defect depend on the nature of the patch and the properties of the adhesive (polyester resin) by increasing the tensile strength and bending load. In the first step, specimen S5 was selected due to its distinctive mechanical properties, which revealed maximum values of tensile strength, toughness and bending load respectively 47,42014 MPa, 2357,42 kJ m⁻³ and 488,3 N. In the second step, the selected sample (S5) was used as a patch to repair API X52 pipeline, which has semi-elliptical defects where the bending load is 31.4246 kN. According to the obtained results, the patch efficiency is 103 % for defects with a/t < (0,3), which can be, restored 100 % of the mechanical properties. Therefore, repairing API X52 pipeline using hybrid patch (Jute reinforced with Steel wires) with shallower defects can be a successful technique.

用金属丝加固天然纤维黄麻并将其用作 API X52 管道按 a/t 比腐蚀的半椭圆形缺陷补丁的实验研究

本研究的目的是评估用钢丝增强的黄麻（含/不含玻璃纤维）混合补丁修复有缺陷的 API X52 管道的效率。根据 ASTM 3039 和 D790 标准，使用黄麻纤维、玻璃纤维和钢丝对五个试样进行了测试，以提高其机械性能。实验结果表明，混合材料（合成材料和天然材料）修复 API X52 管道缺陷的效果取决于补丁的性质和粘合剂（聚酯树脂）的性能，可提高拉伸强度和弯曲载荷。第一步，选择试样 S5，因为它具有独特的机械性能，其拉伸强度、韧性和弯曲载荷的最大值分别为 47,42014 兆帕、2357,42 千焦 m-3 和 488,3 牛。根据所得结果，对于 a/t < (0,3) 的缺陷，修补效率为 103%，可以 100% 恢复机械性能。因此，使用混合修补剂（黄麻加固钢丝）修复 API X52 管道较浅的缺陷是一项成功的技术。

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.
