One section pipe, only 32m and dia=32in, is applied for conveying water from one pond to another pond with the atmospheric conditions . Can it be rolled and welded from ASTM A36?
In my opinion, A36 can be selected as shell of tank, so it also can be shaped and welded as the 32in pipe. Is my...
Recently, I take part in a water pump station project and select the foot valve for this project, which is applied at inlet of centrifugal pump, in order to prevent foreign material in water from entering the pump. And the foot valve is not often adopted at Petroleum Project, usually used in...
As I know, in the ASME B36.10 the pipe is classified to SCH.No, for sch10,20,40 etc; in API 5L, the pipe is identified as ODxw'th. In ASME B36.10, it is stated that" Pipe of size of wall thickness other than those standards, XS, XXS and sch number were adopted from API 5L. It is not considered...
It is well know that for the buried pipeline the anchor shall be applied before the the pipeline out of underground. In the manual calculation for it, the "End movement of buried pipeline" is a critical parameter. This calculation is performed according to "Anchors for Cross-Country Pipelines...
ndeguy, thank you so much for your quickly and valuable point. I am a designer for a buried crude oil transmittion pipeline. And puzzled to select how much percentage shall be applied to inspect the welding point. Because in my opinion the 100% RT is more expensive than 10% RT, and require more...
Recently, I take part in a project and come across a problem on the NDT inspection. Usually, the 10% random RT for the buried pipeline is enough, but in this project, the 100% RT is required and it is mandatory. Who can enlight me to persuade them to convince that 10% RT is enouth.
Your...
Thanks. I think so. It is due to the physical properties of the materials. I heard the PE loose tubes are more used in the US market and the PBT loose tubes are more used in our country. The pp loose tubes are more suitable the low temperature. PE is softer, higher shrink rate, and more flexible...
I know the PBT(polybutylene terephthalate), PP(Polypropylene) (polyethylene) and PE (polyethylene) that be used the material of fiber loose tube. I want to know the difference of them, and which one is the best.
Ths.
Regarding the allowable stress of API5L Gr.B and SA-234 WPB, you are right, but i don't think to check them with ASME B31.3 but with ASME B31.4. In addition, SA-694 is listed in the Appendix A of ASME B31.4.
In the other hand, the allowable stress difference of SA-694 and API5L Gr.B is so...
Firstly, i correct a mistake, the pipeline is API5L Gr.B. Thank Metengr for your so quickly response. This barred tee is used in curde oil transportation pipeline. If somewhere is not clear, please tell me, i am very glad to provide the detail information, because i have been thinking for a long...
Thank your enlightening me in advance. I am taking part in a project on the detailed design stage. With regard to the material for Barred Tee, in the owner's specification the material is A694 F65, but in my opinion the A234 Gr.WPB is sufficient to the condition due to the pipeline is A106 Gr.B...
