压力管道中介质的火灾危险性包含GB50160《石油化工公司计划防火规范》及GB 50016－2006《修建计划防火规范》中规则的甲、乙类可燃气体、液化烃和甲、乙类可燃液体。工作温度逾越其闪点的丙类可燃液体，应当视为乙类可燃液体； 液化烃、可燃液体的火灾危险This clause defines that the characteristic data, and inspection and test results in quality identification document mainly indicate the detection and test results of chemical composition analysis, tensile test, flattening test, flaring test, supersonic detection, eddy current test and etc. When dispute exists, necessary analysing inspection shall be performed, which mainly indicates th

e analysing test for mechanical performance and chemical composition. “Dispute” mainly indicates the inconformity of characteristic data and with the standard or incomplete characteristic data and etc. 5.1.7　关于检查查验的程序与选用合格品的规则，契合GB/T 19000质量办理规范需求，也有利于推进管道构成件出产公司进步商品的质量办理，然后保证建造工程的质量。 5.1.7   For the specification of spot test procedure and qualified product selection, GB/T 19000 quality management standard shall be complied with so as to improve the product quality management of piping constituent elements enterprise, thus the engineering works quality can be ensured.的焊接技术一样。定位焊的焊缝长度宜为10mm~15mm、厚度为2mm~4mm，且不超越壁厚的2/3。定位焊的焊缝不得有裂纹及其他缺点。 7.2.11 Tack weld shall be the same with welding process of formal welding. Length of seam may be 10mm~15mm and thickness may be 2mm~4mm and not larger than 2/3 of wall thickness. There shall be no crack and other defects on the seam. 7.2.12　在合金钢钢管上焊接组对卡具时，卡具的原料应与管材一样，不然使用焊接该钢管的焊条在卡具上堆焊过渡层。 7.2.12   If assembled fixture will be welded onto alloy steel pipeline, material of fixture shall be the same with that of pipeline. Otherwise, use the electrode to weld an intermediate layer on fixture. 7.2.13　焊接在管道上的组对卡具不得用击打或掰扭的办法撤除。 7.2.13 Assembled fixture welded on pipeline can’t be removed by knock or breaking off with fingers and thumb. 7.2.14　当选用怕氧乙炔焰切开合金管钢管道上的焊接卡具时，应在离管道外表3mm处切开，然后用砂轮进行修磨。有淬硬倾向的资料，修磨后尚应作磁粉检测或浸透检测。 7.2.14   If using oxyacetylene flame to cut welded fixture on alloy steel pipeline, shall cut at the point 3mm away from surface of the pipeline, and then grind the surface with grinding wheel. Magnetic particle test shall be done for material that may be quenched after grinding. 7.3　焊接技术需求Requirement for welding procedure 7.3.1　不得在焊件外表引弧或试理判定的输出应当包括与以下方面有关的任何决议和方法： 　　1质量处理系统及其进程
