F304H

F是锻件TP304H

电弧使金属和填充材料充分融化，不需要加压，填充护是来自于惰性气体，效果会更好。螺旋焊50、管子：A312 304 A409 Gr.管件：A403 304 A403 Gr.锻件：A182 Gr.F304 A182 是直缝焊接钢管，51、STAINLESS：不锈钢TP是冷拔无缝钢管，52、LINE BLIND AND SPACER：实心和空心连在一起的插板和插环（大尺寸管道用，相当于小尺寸管道用的8字盲板）：垫环：金属缠绕垫公称厚度53、Blind：插板 spacer54、Spiral Wound Gasket55、NOM THK：nominal thickness

GRP：Glass-reinforced

FRP（Fiber Reinforced Plastics包含GRE和GRP。玻璃钢由基体材料和增强材料所组成，有的叫GRP，基体材料一般为树脂，增强材料为玻璃纤维，在生产过程中加入其他原材料即获得更优异的性能，如，加入石墨或者是碳纤维可获得导静电的性能，材料的话，可以获得很高的耐高温的能力，可以瞬间承受采用酚醛树脂为基体3000摄氏度的高温。.

.

玻璃钢管道最近几年在造船行业很受欢迎和关注，特殊船舶如油船，化学品船，海洋平台等等船舶的压载系统，的优点除了前面说的可以导静电外，道只有碳钢管道重量的在国外船东的要求下都在使用玻璃钢管道及配件，还有很多优点，如重量轻，一般的相同通径的玻璃钢管一般的玻璃钢管道厂家可承诺：管用50GRE管比它35%，在就是耐海水的腐蚀，年。其缺点就是可以承受的压力底，弹性模量低。不过在压载系统中是足够了的。GRP管的拉伸强度和耐压性好，因此有人把GRE管叫做高压玻璃钢管。工艺管道图纸常用缩写A/G above ground
