INTEGRALLY REINFORCED FORGED BRANCH OUTLET FITTINGS -
SOCKET WELDING, THREADED AND BUTTWELDING ENDS
1. SCOPE
1.1 This Standard Practice covers essential dimensions, finish, tolerances, testing, marking, material,and minimum strength requirements for 90 degree integrally reinforced forged branch outlet fittings of buttwelding, socket welding, and threaded types.
1.2 Fittings manufactured to this standard are designed to make a fully reinforced branch connection in accordance with applicable piping code requirements, when attached, at an opening in a run pipe by means of a full penetration weld.1.3 Fittings may be made to special dimensions,size, shape, tolerances, or of other wrought material by agreement between manufacturer and the purchaser.
2. SERVICE DESIGNATION
2.1 These fittings are designated by their size,type,and class, as shown in Table l.
2.2 Design temperature and other service conditions shall be limited as provided by t

整体钢筋锻造分公司出口配件-
插座焊接， 线程和对焊 完
1 。范围
1.1本标准做法包括基本层面，完成后，公差，试验，标记，材料，强度要求的最低90度整体出口处钢筋伪造配件对焊 ，插座焊接，螺纹类型。
1.2配件制造的这一标准的目的是让一个完全钢筋连接处按照适用管道代码的要求，在重视，在一个开放的运行管的方式全面渗透焊缝.
1.3配件，可向特殊层面，大小，形状，公差，或其他造成材料制造商之间达成的协议和购买。
2 。指定服务
2.1这些配件指定的大小，类型和等级，如表湖
2.2设计温度和其他服务条件应限于所规定的适用的管道代码或法规的材料，建造的拟合。在这些限度内允许的最大压力，业务基金拟合应是连续计算的无缝运行管等效材料（如比较的组成和力学性能在各自的材料的规格） 。壁厚使用这种计算应是比较B36.10M的规模和适用的时间表管减少了适用于制造公差和其他津贴（如线程津贴） 。
2.3腐蚀允差和任何变化允许应力由于温度或其他设计应适用于管道及配件一样的。管壁厚相当于每类恰当的评价的目的不仅是表升
3 。尺寸
3.1出口处大小考虑这一标准表显示若湖尺寸大小配件应限于出口规模的核动力源升/ 2和更大。
3.2运行' （头）管径仅限由管径范围列出每种配件类。
3.3制造商可以选择巩固运行大小某一行业规模由于经济原因，提供指定的巩固差距之间的距离和运行管半径拟合入口半径不超过“ l/16 ” （ 1.6毫米） 。
