On a 18" flare line we have installed a 16" nozzle using a split Tee. The WT of the pipe is 3/8", WT of the Tee is 30 mm. This tee is welded to the run pipe with two circumferential welds.
Acc. to B31.3 a PWHT is necessary. Is it allowed to machine the Tee and the welds in order to reduce...
I am trying to determine wether a tangential nozzle (with external loadings) on a pressure vessel needs a reinforcing pad. Does ASME address this issue?
To the best of my knowledge, API 610 does not specify whether the loads obtained from operating or design conditions should be used when comparing nozzle loads to the allowables.
Is it up to the discretion of the client or are there fixed rules?
How would I go about building a CII-model of a cone/reducer that on one side is 28" and on the other 16"? WT = 6 mm.
Perpendicular to the centerline of this reducer is a nozzle of 28" diam.
Is modelling a pipe of average diameter (22") with a rigid element (represented by...
In many adverts in UK newspapers the term 'Chartered Engineer'is used. What is a chartered engineer?
The reason I am asking is because normally in Europe, according to law, there is 'free transportation of people and goods'. In reality the acceptance of foreign degrees/diplomas causes...

When a straight pipe is subjected to external presure, there is no way of telling which side will give first (Top, bottom, left or rigth, ...). But what about elbows? Being that they aren't 100% symmetrical, is one side more succeptible to buckling than the other?
What are the advantages and/or disadvantages in applying a 45 degree bevel at the end of the tail pipe of a safety valve? I am thinking about forces, noise,...
Unless I have misinterpreted your question, the answer to your question can be found in the Caesar II Application Guide - Chapter 3 - Restraints.
Vertical dummy legs on bends and horizontal dummy legs on bends.
There is no specific code or standard that specifies these values.
The determination of the friction coeff. is based on tests.
Normally we use this value (0,3), present it to the client and ask for his approval.
As for literature : a (Dutch) book "Staalconstructies" (Steel...
Sir,
in our engineering company (Europe based)following friction coefficients are used :
- steel to steel : 0.3
- PTFE to steel : 0.1
- lubricated PTFE to steel : 0.05
These values have been aproved by several government agencies that are in charge of approving design and calculations...
