The procurement and application of pipes for industrial pipeline transportation systems have been formulated for induction heating bends, pipe fittings, This document is based on ISO 15590-4, and refers to relevant domestic and foreign standards. The research results and practical experience of the application basic research and technical standards of cold-bent pipes for oil and gas pipeline construction. GB/T 29168 "Bends, fittings and flanges for pipeline transportation systems in the petroleum and natural gas industry" is planned to consist of four parts. --- Part 1.Induction heating pipe bending. The purpose is to specify the application of carbon steel or low alloy steel seamless steel pipe, high frequency welded pipe and straight seam buried pipe Technical requirements for the design, manufacture and inspection of induction heating bends made from arc-welded steel pipe as parent pipe. --- Part 2.Pipe fittings. The purpose is to specify the pipe fittings applicable to the use of carbon steel or low alloy steel plates, seamless steel pipes and welded steel pipes. Technical requirements for the manufacture and inspection of welded pipe fittings. --- Part 3.Flanges. The purpose is to specify neck welding flanges and blind flanges suitable for carbon steel or low alloy steel forgings, as well as anchoring Technical requirements for the manufacture and inspection of flanges, slip-on flanges and orifice flanges. --- Part 4.Cold-bent pipes. The purpose is to specify the radius of application of low-carbon low-alloy seamless and welded steel pipes not less than 5OD, Technical requirements for the design, manufacture and inspection of cold-bent pipe produced by cold bending in factories and on site. During the construction of pipeline engineering, in order to meet the needs of medium diversion, diversion and relief, and improve the main steel pipe in the pipeline system under harsh loads, Due to the abnormal external loads, a large number of pipeline structures are often required in the construction of pipeline laying, valve rooms, stations and booster stations. Pipeline structural parts can be divided into elbows, pipe fittings and flanges according to their geometric shapes and application environments. Different, pipe bending can be divided into induction heating pipe bending and cold bending, tees can be divided into welding tees, hot extrusion tees, cold pressing tees, etc. Based on factors such as type, geometry, production and processing technology, and inspection requirements, GB/T 29168 is based on different bending processes. GB/T 29168 divides pipe bending into Part 1.induction heating pipe bending and Part 4.cold bending; Part 2.carbon steel or low alloy pipe bending. Technical requirements for pipe fittings made of seamless steel pipes and welded steel pipes, such as elbows, caps, tees, reducers, etc.; Part 3 is carbon steel And technical requirements for low alloy steel forged flanges. Bend pipes for oil and gas industry pipeline transportation systems, Pipe fittings and flanges Part 4.Cold-bent pipes1 ScopeThis document specifies the design, manufacture, testing and maintenance of cold-bent pipes for pipeline transportation systems designed in accordance with GB 50251, GB 50253 and GB/T 24259. Inspection and testing, technical requirements and marking. This document applies to cold-bent pipes with a radius of not less than 5OD, which are cold-bent in factories and on-site for use in pipeline transportation systems in the petroleum and natural gas industries. manufacturing and inspection. This document applies to cold-bent pipes made of low carbon low alloy seamless and welded steel pipes. Note. These materials are typical C-Mn steel or low alloy steel, which are consistent with the strength level of pipeline steel pipes in GB/T 9711. This document does not apply to pipe bends produced using other manufacturing processes.2 Normative referencesThe contents of the following documents constitute essential clauses of this document through normative references in this document.
