标准摘要
[中文适用范围]: 本标准涵盖了用于原油@石油产品@燃料气体@二氧化碳@氮气@的压缩@泵送@和传输的碳钢和低合金钢管道中的对接@角焊@和承插焊的气焊和电弧焊。适用@涵盖配电系统上的焊接。它适用于新建建筑和在役焊接。焊接可以通过保护金属电弧焊@埋弧焊@气体钨极电弧焊@熔化极气体保护焊@药芯焊丝电弧焊@等离子弧焊@氧乙炔焊@或闪光对焊工艺或通过这些工艺的组合来完成使用手动@半自动@机械化@或自动焊接技术或这些技术的组合。焊缝可通过定位焊或滚焊或通过定位焊和滚焊的组合来产生。本标准还涵盖了射线照相@磁粉@液体渗透@和超声波检测@的程序以及适用于通过射线照相@磁粉@液体渗透@超声波@和目视测试进行破坏测试或检查的生产焊缝的验收标准方法。以美国习惯单位 (USC) 单位或公制单位 (SI) 表示的值应单独视为标准。每个系统都应独立于其他系统使用,不得以任何方式组合值。本标准中描绘的图形并非按比例绘制。旨在使按照本标准执行的所有工作达到或超过本标准的要求。虽然该标准很全面@,但它可能无法解决可能出现的所有问题。缺乏指导或要求不应被视为禁止基于合理工程判断的特定活动或方法。例如@其他行业标准@可靠的工程测试和分析@或既定的行业实践可以为建立合理的工程判断提供有用的参考。 [外文原描述]: This standard covers the gas and arc welding of butt, fillet, and socket welds in carbon and low-alloy steel piping used in the compression, pumping, and transmission of crude petroleum, petroleum products, fuel gases, carbon dioxide, nitrogen and, where applicable, covers welding on distribution systems. It applies to both new construction and in-service welding. The welding may be done by a shielded metal-arc welding, submerged arc welding, gas tungsten-arc welding, gas metal-arc welding, flux-cored arc welding, plasma arc welding, oxyacetylene welding, or flash butt welding process or by a combination of these processes using a manual, semiautomatic, mechanized, or automatic welding technique or a combination of these techniques. The welds may be produced by position or roll welding or by a combination of position and roll welding. This standard also covers the procedures for radiographic, magnetic particle, liquid penetrant, and ultrasonic testing, as well as the acceptance standa
