This document was first published in.2012, and this is the first revision.IntroductionInduction heating elbows, pipe fittings and flanges are indispensable and important reversing structural parts for the construction of long-distance pipelines and station valve chambers. They are standard stones. The procurement and application of pipes for pipeline transportation systems in the oil and natural gas industry have formulated induction heating bends for pipeline transportation systems in the oil and gas industry. A series of technical documents for pipes, fittings and flanges. In the formulation of this document, the relevant domestic and foreign standards such as ISO 15590-1 have been referred to, and the In recent years, the research results and practical experience of applied basic research and technical standards for elbows used in the construction of oil and gas pipeline engineering. According to product category Type, production process, geometry and inspection requirements and other factors, GB/T 29168 "Induction heating bend for pipeline transportation system in petroleum and natural gas industry Pipes, fittings and flanges are divided into 4 parts. ---Part 1.Induction heating elbow; ---Part 2.Pipe fittings; ---Part 3.Flanges; ---Part 4.Factory cold bend pipe. In the process of pipeline construction, in order to meet the requirements of diversion, direction change and mitigation of the transmission medium, and to improve the pipeline system under severe load, the main line steel pipe The effect of the abnormal external load on the pipeline often requires a large number of pipeline structures in the on-site construction of pipelines, valve chambers, station yards and pressurized stations. Pieces. Pipeline structural parts can be divided into elbows, pipe fittings and flanges according to their geometry and application environment. According to the production process and processing method Different, elbows can be divided into induction heating elbows and cold elbows, tees can be divided into welding tees, hot press tees and so on. This document combines product categories Based on factors such as type, geometry, production and processing technology, and inspection requirements, the GB/T 29168 "Petroleum and Natural Gas Industry Pipeline Transmission Induction heating elbows, pipe fittings and flanges for the delivery system are divided into four parts. According to the different requirements of the elbow processing technology, this document Divided into the first part of induction heating elbow and the fourth part of cold elbow. Part 2 is the use of carbon steel or low alloy steel seamless steel pipes and welded steel pipes Technical requirements for manufactured pipe fittings, such as elbows, pipe caps, tees, reducers and other products. Part 3 is the pipeline transportation system of the oil and gas industry Technical requirements for forged flanges of carbon steel and low-alloy steel. For oil and gas industry pipeline transportation system Induction heating elbows, fittings and flanges Part 1.induction heating elbow1 ScopeThis document specifies the design, materials, manufacturing process, mechanical properties, testing and Inspection, marking, transportation, storage and protection requirements. The elbow made in accordance with the provisions of this document is suitable for natural gas, crude oil and Refined oil pipelines required by product standards. This document is applicable to induction heating with carbon steel or low-alloy steel seamless steel pipes, high-frequency welded pipes and longitudinal submerged arc welded steel pipes as the parent pipe. Hot elbow. Note. These materials are typical C-Mn steel or low-alloy steel, consistent with the strength level of GB/T 9711-2017 and ISO 3183.2019 line pipe. The two product specification levels (PSL) of induction heating bends specified in this document are consistent with GB/T 9711-2017 and ISO 3183.2019. correspond. This document does not apply to elbows for pipelines produced by other processes.2 Normative referencesThe contents of the following documents constitute the indispensable clauses of this document through normative references in the text.
