The steel pipes used at numerous chemical plants transport millions of gallons of liquids every single day. Sometimes, what is delivered is searingly hot. Other times, abrasive chemicals are sent through. Or, they can be both.
If not properly lined, these pipes can corrode quickly. It may simply result in poor sanitary conditions. Conversely, the chemicals can contaminate another mixture. When that happens, money is lost due to repairs and downtime.
The Way to Mitigate Corrosion
There is a way to mitigate corrosion and maintain continuous production: rubber lined pipe. Coating the interior with this material allows liquids of varying temperatures and corrosive states to flow without potential damage or exposure to other chemicals.
How are the Pipes Lined?
The lined pipes purchased at companies like Moon Fabricating aren’t made that way. There’s a process of installation and quality assurance before it gets placed on the truck toward a plant.
First, the pipe to be lined is examined to ensure it is fit for its purpose. Those made of steel or stainless steel seem to work the best to handle the flow of chemicals. Next, the interior is scrubbed with a wire brush or sandblasted to remove any rust or scaling.
When the pipe is clean, sheets of rubber are placed inside. They are bonded to the interior through the process of high-pressure steam vulcanization. This cures the rubber to ensure it properly molds to the pipe material.
The last and most important step is quality assurance. Once cooled, the rubber lining is examined for any defects like pin holes. It is then hydro tested to ensure liquids flow through without any leakage or damage. If given the green light, the pipes are prepared for shipping.
Determine What Your Pipe Supplier Does
Unsure if your pipe supplier does this to install rubber lining? Ask them for a description of their process. If you’re nearby, request a time to stop by and see the process for yourself.
