日标方管：为什么叫法兰盘-应用法兰(flange)又叫法兰盘或突缘盘。使管子与管子相互连接的零件，连接于管端。法兰上有孔眼，螺栓使两法兰紧连。法兰间用衬垫密封。法兰管件(flangedpipefittings)指带有法兰(突缘或接盘)的管件。它可由浇铸而成(图暂缺)，也可由螺纹连接或焊接构成。法兰连接(flange，joint)由一对法兰、一个垫片及若干个螺栓螺母组成。垫片放在两法兰密封面之间，拧紧螺母后，垫片表面上的比压达到一定数值后产生变形，并填满密封面上凹凸不平处，使连接严密不漏。

STKR400方矩管：
T8A工具钢的热处理工艺为：79~82℃水或油淬，16~18℃回火，硬度58~61HRC。W18Cr4V、W6Mo5Cr4V2为高速工具钢，具有很高的硬度、抗压强度和耐磨性，但韧性较低，工作时有可能产生崩刃或断裂，而且价格较贵。建议采用低温淬火、快速加温淬火等工艺措施来改善其韧性。对于工件批量较大的厚板冲裁模，可以用W18Cr4V、W6Mo5Cr4V2钢做凸模，Cr12MoV钢做凹模。W18Cr4V钢的推荐热处理工艺：122~125℃淬火；~57℃回火3次。
