Spectacle blind are used for easy change-over when physical isolation of pipe is needed.
But I always have a question in mind, how can we remove the old gasket as well as adding a new gasket within the limited working space?
Many thanks!
In order to absorb the thermal expansion of an above ground steel pipe, it is decided to install an expansion joint for the pipe. However, when it comes to the specification of the expansion joint, I don't know how to start. Is there any standard/reference which I could refer to?
Many thanks!
Hi all,
Recently, I hear about a process called "flow induced crystallization (FIC)".
After some preliminary study, it seems to me that FIC refers to the crystallization of polymer at temperature above its melting point due to the present of shear stress. And this kind of crystallization...
Hi all,
It is common for us to connect HDPE pipes by means of butt fusion. However, I found that there are different standards on fusion parameters.
For example,
DVS 2207-1
WIS 4-32-16
GIS PL2/3
ISO 21307
UNI...
Each of the above standards refer to their specific set of fusion parameters...
