JB/T74-201*引言JB/T7486-201*钢制管路法兰系列标准修改采用EN1092-1xx法兰及其连接管道、阀门、管配件及附件用圆形法兰，PN标记第1部分钢制法兰和GB/T91129124-xx钢制管法兰系列标准的有关内容。 本系列标准包括以下9项标准JB/T74-201*钢制管路法兰技术条件JB/T75-201*钢制管路法兰类型与参数JB/T79-201*整体钢制管法兰JB/T81-201*板式平焊钢制管法兰JB/T82-201*对焊钢制管法兰JB/T83-201*平焊环板式松套钢制管法兰JB/T84-201*对焊环板式松套钢制管法兰JB/T85-201*翻边板式松套钢制管法兰JB/T86-201*钢制管法兰盖。 本系列标准将钢制管路法兰分为两个系列，其中系列1法兰的尺寸与EN1092-1xx标准连接尺寸互换，但法兰适用的钢管外径与EN1092-1xx标准不同，另外本系列标准没有包括EN1092-1xx标准的PN 250、PN320及PN400三个公称压力等级，也没有包括EN1092-1xx标准的O型圈密封面型式。 本标准系列1法兰尺寸与GB/T91129124中相同型式、相同压力级的系列法兰尺寸相同，本标准的系列1法兰优先推荐使用；系列2法兰的尺寸与原标准系列2法兰的尺寸基本相同，仅适用于老设备的维修与更换。 本系列标准将原来的16项标准整合为9项标准，并扩大了标准的参数与范围。 JB/T74-201*钢制管路法兰技术条件1范围本标准规定了钢制管路法兰及法兰盖的材料、压力-温度额定值、尺寸与公差、连接密封面、紧固件及垫片、焊接端型式及尺寸、加工制造、试验、检验与验收、标记及供货要求。 本标准适用于JB/T7586中规定的钢制管路法兰及法兰盖。 2规范性引用文件下列文件对于本文件的应用是必不可少的。 凡是注日期的引用文件，仅注日期的版本适用于本文件。

本标准没有涉及到法兰材料的选用准则，用户应考虑材料在实际使用过程中性能变坏的可能性。 用户应该注意碳化物相转变成石墨，铁素体材料的过分氧化，奥氏体材料对晶间腐蚀的敏感性等问题。 3.4当使用条件对材料具有某些特定的要求时，如需要材料进行特定的热处理，则用户应在订货合同中说明。 3.5材料的力学性能应从代表材料的最终热处理状态的试样中获得。 4压力温度额定值4.1法兰的压力-温度额定值应符合表2表11的规定。 4.2根据压力-温度额定值确定不同材料在不同使用温度下的最大允许工作压力（MPa），对于中间温度允许用线性内插法确定在该温度下法兰的最大允许工作压力（MPa）。 对于特殊的材料，其压力-温度额定值根据设计的规定。 4.3如果在一对法兰连接中的两个法兰的压力温度额定值不相同，那么这一对法兰的压力-温度额定值由两个法兰中较低的一个法兰所决定。 4.4法兰连接由法兰、垫片和螺栓等相互分离、相互独立而又相互关联的元件组装而成，法兰连接还受装配的影响。 在选用这些元件时必须进行严格的控制，使法兰连接具有良好的密封性。 为了使法兰连接在使用中获得良好的密封性能，需要采取一些特殊的技术，如控制螺栓的预紧力矩等。 4.5法兰在低温下的最大允许工作压力（MPa）不应大于常温时的最大允许工作压力（MPa）。 4.6用于高温或者低温下的法兰，应该考虑连接管道和设备因温度变化而产生的力和力矩会引起法兰泄漏的危险。 用于高温下的法兰，随着使用温度的升高，法兰、螺栓和垫片将会逐渐松弛，螺栓的载荷随之逐渐降低，法兰的密封性能相应的逐渐下降。 用于低温下的法兰，尤其是一些含碳的钢制法兰，其韧性显著降低，在这种情况下，法兰有可能无法安全地承受冲击载荷、应力和温度突变，或者会产生高的应力集中。 因此，要求根据有关标准测试材料在低温下的冲击性能，以保证法兰在低温下的安全使用。 5尺寸与公差5.1尺寸5.1.1法兰的尺寸应符合JB/T 75、JB/T 79、JB/T 81、JB/T 82、JB/T 83、JB/T 84、JB/T85及JB/T86的规定。 5.1.2当密封面型式为突面（RF）、凹面（F）及槽面（G）时，密封面凸台与法兰面之间的过渡一般采用直角，也可以根据制造厂的设计采用45倒角或圆角。 5.1.3与钢管对焊连接的法兰，法兰颈部厚度S应不小于钢管的厚度，用户应在订货时注明钢管的规格。 本系列标准中所列的S值仅适用于用户未提出具体要求的场合。
