Method of pipeline installation
Thread Content
Are there any standards regarding whether pipelines should be installed overhead or buried underground (other than for water lines)? For the alkali solution pipelines in my installation, they are mostly buried underground, but crystallization often causes blockages that are difficult to resolve
It is best to install pipelines above ground to prevent leaks from contaminating the groundwater system
Now, it is advocated to be overhead for easier inspection and maintenance.
The early designs used ground wires, which made handling difficult. In our system, the pipelines for the alkaline solutions and alkaline residues run underground; if crystallization occurs, it is very hard to deal with it
