In numerous occasions, conduit pipes or pipelines will require to be cleaned and disposed of unwanted materials, and even inspected. These activities are mainly aimed at ensuring their dispensation of service remains effective and exemplary, as intended. To facilitate these upkeep practices, pigging comes in. It is a process which basically involves equipment referred to as pigs, which greatly help in maintenances of piping systems. Loading a pig into pipeline must nonetheless not disrupt normal operations and flow of medium.
It involves inserting this pig device into a section of the conduit pipes called launching station or simply launcher, cutting down to normal diameter. Consequently, the launcher is closed and then the product that is being conveyed by the conduits, say oil or water, considering it is driven by pressure, pushes it down the conduits pipes till it reaches its intended destination or trap, called receiving station or colloquially pig catcher.
For umpteenth years, pigging has usually been used in oil industries and other large plants to clean conduits especially those with large circumferences. Currently, there has been an upsurge in usage of smaller circumference pigging systems, across various batch plants and oil firms. This has been deemed as a move to revamp efficiency and also reduce overhead costs.
Pigging comes in handy throughout the various steps involved in the transfer procedure, for example during the filling, refilling, blending, emptying not to mention, storage of mediums. Analyses have constantly shown that pigging has become popular across major water, oil, gas and other pipelining companies and plants transferring products such as chemicals, toiletries, paints, etc.
Using pigging has also proved to be very essential because it reduces instances of cross-contamination. It is additionally used during the process of emptying the products from the pipes. Normally, pigging should be done at the very end of the transferring process, though certain circumstances may compel it to be carried out amidst the process.
Pigging has myriad advantages. Firstly, it plays critical role in mitigating environmental effects posed by flushing these lines with certain cleansing agents like solvents. These cleansing agents were then subjected to outflowing treatments. Today, pigging provides very specific interfaces and therefore these problems are no longer encountered.
In addition, grisly incidents may also occur if the closure doors are still opened, when there is a high concentration of hazardous toxins such as H2S still inside the particular vessel. Another one is whereby vent valves still remain opened when the particular vessel is still being pressurized with the product or medium in it.
Vent and main valves should be fully closed when the pipes are being pressurized or filled with the mediums. These are just a few precautionary strategies to mention, though there are a myriad of others. They should all be critically put into consideration, so that situations that pose a danger to life are reduced or completely stopped. Valve interlocks should also be installed, to avoid occurrence of menacing incidents.
