On November 12, 2010, the 5-day training course on design and manufacturing technology of FRP sand pipe was successfully concluded in Changzhou, Jiangsu Province. Zhang Linwen, executive deputy director of the National Center for Quality Supervision and Inspection of FRP Products, Hu Zhongyong, secretary general of the National Technical Committee for Standardization of Fiberreinforced Plastics, Dr. Chen Jianzhong from Wuhan University of Technology and other FRP industry experts attended and gave lectures. Yin Zheng, secretary general of FRP Branch of Chinese Society of Ceramics, hosted the lectures. A total of 48 people from related enterprises, research institutes and universities participated in the training.
This training aims to improve the professional skills of professional technical personnel of FRP sand pipe and the technical level of sand pipe company. The content mainly involves the preparation of GB/T 21238-2007 standard of FRP sand pipe, the structure design, material design, process design and the application of design software of FRP sand pipe. Inspection management of water pipe products and quality control and construction technology of FRP sand pipe.
First of all, Hu Zhongyong, secretary general of the National Technical Committee for Standardization of Fiber-Reinforced Plastics, gave a detailed explanation on the establishment of the fiberglass reinforced plastic sand pipe GB/T 21238-2007. After briefly describing the background, purpose, process and acquisition of national standard, it focuses on the specific content of the standard provisions. For raw materials such as reinforced materials, resin and the properties of granular materials and the size of the sand glass steel tube and barcol hardness and resin unsolvable contents, straight pipe, initial wall components in mechanical properties, long-term performance and health performance and test methods, test rules, packaging, transportation and storage of the professional interpretation and description, Make the trainee understand GB/T 21238-2007 more thoroughly.
Dr. Chen Jianzhong from Wuhan University of Technology introduced the purpose, content, effect, structural resistance, structural design method and composite material design foundation and design of buried glass fiber reinforced plastic sand pipe structure design for water supply and drainage engineering The design content, design formula and the advantages and disadvantages of the design and the FRP pipeline structure design basis, design content, pipeline performance parameters, the role of the pipeline, structural design calculation, construction provisions, safety factor and so on were explained in detail, and enumerated the examples, the site demonstration.
Zhai Jiye, General Manager of Jiangsu Fuling Chemical Co., Ltd., gave a brief introduction on the production status and development trend of FRP sand pipe, which closely followed the hot topics of The Times and was wonderful and vivid.
Ma Yuequn, deputy general manager of Jiangsu Fuling Chemical Co., Ltd., discussed the selection of unsaturated polyester resin for glass fiber reinforced plastic sand pipe, the connotation, characteristics, classification, production process of unsaturated polyester resin and the production status of unsaturated polyester resin in China. The selection of resin for lining layer and structure layer as well as the detection of resin before use are described in detail. The technology, performance index and problems needing attention of selection of unsaturated polyester resin for glass fiber reinforced plastic sand pipe are described.
Hebei HaoHua like glass reinforced plastics co., LTD., the chief engineer wang lei is of pipeline design, the manufacture technology of glass fiber reinforced plastic sand process design connotation and status, to the requirements of the process management principle, method, and the main problems existing are introduced in detail, and the typical problems in sand glass steel pipe production carried on the thorough analysis.
Mr. Li Guoshu, General Manager of Jiyuan Technology Co., Ltd., Shijiazhuang Development Zone, Hebei Province, introduced the characteristics of precision, computerization and automation of modern FRP pipeline design technology, reviewed the development process and characteristics of FRP pipeline design software, and listed the specific situation and applicability of FRPCAD pipeline design software series. The design software of GB21238 version winding pipe, GB21492 version pipe jacking design software and pipe fittings design software are demonstrated on site. The problems needing attention in the concrete operation are explained in detail.
National glass fiber reinforced plastic products quality supervision inspection center executive deputy director Zhang Linwen to the relevant situation of water pipeline product inspection management made in-depth interpretation. From the definition of quality inspection, work principles and basic key points and quality inspection work to a few aspects, is described in detail the quality inspection is the function of identification, prevention, control and decision making, and to the specific content of the classification, the inspection of the quality inspection has carried on the brief description, focus on the production license products quality inspection requirements, Specific contents such as on-site inspection items and judgment principles of enterprises, appointment requirements of inspection personnel, inspection management and inspection report, etc.
Zhang Zhenhua, chief engineer of Hebei Chengda FRP Co., Ltd., described the quality control of FRP sand pipe and related problems of construction technology. To install construction specifications, delivery plan and acceptance of the goods to the site and the guidance of the supervisor, Ann outfit in factory, pipeline transport, pipe trench FAQ, socket joint, backfill, installation, inspection, maintenance, integral pressure testing and safety production of glass steel sand tube, a series of problems in the construction process carried on the thorough fine send instructions, The corresponding solutions to the problems are also put forward.
Visit Jiangsu Fuling Chemical Co., Ltd
Finally, in order to further strengthen the 5-day learning, the organizer designed a set of engineering project simulation questions to check whether the students have mastered the key technical problems in the design process of FRP sand pipe. They visited Jiangsu Fuling Chemical Co., Ltd on the spot to learn and deepen their impression. The training is co-sponsored by China Society of Ceramic Fiber Reinforced Plastics (FRP) Branch, National Quality Supervision and Inspection Center of FRP Products and National Technical Committee of Standardization of Fiber-Reinforced Plastics. 8 industry experts give on-site lectures with 40 students, lasting for 5 days. The training content is professional, practical, rich and targeted, which is highly praised by the participants.
