I think that the problem with this has to do with expansion and contraction that accompany temprature changes in a material. I agree that the material is thin but one have to understand that the rivet is a type of joint whereby two separate parts are held together by a clamp-like component or...
The following may be the reason:
(1)Most pipe specs, ASME B16 in particular, give a manufacturing tolerance of +/- 12.5%
(2) It coud also be that you did not identify the schedule of the pipe correctly.
(3) Most impotantly, the calibration of the tool used in carrying out the measurement might...
We just completed the IP of an 8" x 3km gas flowline that was installed in 1987. This line has an external bullet ponit defect measuring 16mm long x 11mm wide x 5mm deep at 3 O'clock position with the bultt in place and is a schedule 100 pipe with Nominal wall thickness of 15.1mm. The final IP...
We just concluded the intelligent pigging of an 8"x3km gas flowline that was installed in 1987 but the final IP report from the contractor revealed no defect. This line is a schedule 100 pipe with Nominal wall thickness of about 15.1mm and has a bullet pierce of 16mm length x 11mm width x 5mm...
Hi cooleagues,
I had a proposal to use the alloys in our company but do not have a full grasp of their corrosion properties, chemical composition and application. I will obliged if you could educate me on the above and sent web links where I can get more idea.
Thanks

I am incharge of asset intergrity in my place of work and is saddled with the role of determining facilities retirement. I would be obliged if some one can give me guide on the critera to used in taking decision on the above matter. The piping in question are crude oil and gas production piping...
A corrosive environment said to be sour if H2S(hydrogen sulphide) is present in that environment. If there is none,the environment is not sour.
In other to determine the corrosivity of the flüid in a vessel a knowledge the % composition of the vessel's content is required.The following...
Think these contributions are enough for you as mine will be a repetition of the things already said. So combine these fragments of Knowledge and it will make the good volume of knowledge you require. If you are not satisfied write back so that I can give you more infomation.
I am presently faced with a new challenge of taking charge of the risk based inspection of the surface facilities in my company's crude oil flowstations. Please I will be obliged if someone can give me guidelines on the above subject matter or give link on where to find information on the above...
During the process of start-up of one of our flowstations,while pumping down the high liquid level from a vertical crude oil surge vessel with two pumps, the vessel suddenly imploded. All pumps were immediately stopped, facility closed in and wells secured. Pleases what colud be the...
