4 Abstract: 3PE anticorrosion coating possesses good anticorrosion performance and high mechanical strength. It is widely applied in pipeline engineering. Because of having surplus weld reinforcement height and irregular seam form as well as the influences of polyethylene raw materials and coating process, the quality problems of ununiformity in thickness of 3PE coating and coating thickness reduction on helical seam occur. To solve these problems, the reason analysis is conducted concerning steel pipes, polyethylene raw materials and coating process. And the countermeasures are put forward to ensure product quality. Key words: helical seam submerged-arc welding pipe; coating; 3PE; thickness (39) Research and Manufacture of 3PE Anticorrosion Pipes by Round Mould Negative Phase Formation Method CHEN Biao (Daqing Oilfield Thermoelectric Plant, Daqing , China), CHEN Guang -yu, ZHU Hong-yan, et al. Abstract: A technique producing 3PE anticorrosion pipes using the new process of round mould negative phase formation and the corresponding equipment is presented. The anticorrosion coating at helical seams formed by this technique has the advantages such as small thickness reduction, integral uniformity in thickness, no air bubble, no surface helical line, non-delamination and no crack. This technique is also suitable for production of 3PE anticorrosion pipes with small diameter. The inspected specifications of the products are in accordance with SY/T 0413 Standard. The products have successfully been used in Harbin-Daqing Gas Transmission Project a national key project, and it has got excellent application results.

This paper discusses the key techniques with respect to weldability, welding method, welding material, welding bevel design, welding process evaluation and welding quality examination of the composite pipes and describes their successful applications in practical projects. Key words: composite stainless steel pipe; welding process; welding examination (51) Cold Tightening Assembly Quality Control in High Temperature Pipeline Construction MING Chuan-yang ( China Petroleum First Construction Co., Luoyang , China ), LI Peng, QU De-chen, et al. Abstract: Cold tightening joint should be set up near the compensator of high temperature steam 7

5 pipeline, but the relevant design code only stipulates that cold tightening joint should be positioned in the places favourable to welding and operation. Therefore, the design of cold tightening joint position may be unreasonable so as to bring difficulty to cold tightening assembly. Based on the cold tightening construction of the medium pressure steam pipeline owned by a petrochemical company, this paper expatiates on the method of shifting cold tightening joint to overcome welding difficulty. The results show that the butt welding time for one cold tightening joint decreases from 4 working days with the original construction method to 2 working days with the shifting method. Key words: high temperature pipeline; cold tightening joint; assembly; shift; welding (53) Research and Application of New Welding Process: IWM + FCAW JIN Hong-xing ( Central-Asia Pipeline Project EPC Office of China Petroleum Pipeline Bureau, Langfang , China ), WANG Wei-guo Abstract: The Central-Asia Pipeline Project (CAPP) wriggles through four countries to transport natural gas from Turkmenistan to China via Uzbekistan and Kazakhstan. It becomes the longest and largest strategy energy passage in China after finally being connected with the pipeline named West -East Pipeline Project Phase II at Horgos Town, Xinjiang, China. In order to speed up the pipeline welding construction, the new welding process IWM + FCAW (inner welding machine for root pass plus flux cored arc welding for hot, fill and cap ) was developed and applied in the pipeline project. This article describes in detail the research contents of welding, welding qualification test, equipment preparation for crew, economy analysis of the new weld ing process and its application in CAPP, as well as comparison with the traditional welding process SMAW + FCAW (shield metal arc welding with high cellulose type electrode for root pass plus flux cored arc welding for hot, fill and cap ). The welding speed is roughly doubled.
