请问是否有专家大虾了解ASTM D3299和 RTP-1的具体区别是吧,为什么RTP-1会引起巨大的费用影响。我们的厂家给了一个解释,还请懂行的指点一下。
o ASME RTP-1 demands to have a laminate where the axial and radial mechanical characteristics are similar. To do that, on the composition of laminate, one part can be done by filament winding machine but it is necessary to do another part by hand lay-up layers.
o The lengths of junction knuckles and nozzles reinforcements are longer on ASME RTP-1
o Additionally the ASME RTP-1 require that a Professional Engineer certificate must be issued
