Hex head bushing if one-size reduction should not be used in services where they might be
subject to harmful loads and forces other than internal pressure.


罗纹请求(这对您很主要
1、以上均为锻钢高压实心堵头,额外压力可大410KG压力。
2、咱们惯例备货的罗纹有NPT(美制)60度锥管罗纹,PT(英制)55度锥管罗纹,此中RC/ZG/R,英制在国际很是经常使用,又称水管牙,美制很是少见,定货时请务必确认,二者不能通用。
3、咱们工场不接201、301等低质不锈钢资料的定单,最低为304材质起做。
4、若是您须要G罗纹,需定做,局部G外罗纹能够用PT(英制罗纹取代),外罗纹PT能够毗连G内罗纹,反过去就不能用。
5、管件多少尺寸制作根据ASME B16.11及GB/T14383,罗纹制作规范为BSPT(ISO7/1),NPT(ASME B1.20.1)
