Discovered damage in your pit or chest linings? Regular inspections are key to planning work for mill outages. Once you’ve made an assessment, you have an idea of what you’ll need to plan for on the schedule and for your budget. Most people still wait to perform the repairs and assume the damage will have progressed by the outage.
Why not make the temporary repairs during the inspection? It could slow or prevent any additional damage that might continue to progress until your planned project date.
Take a look at some options that will keep the surprises at a minimum when you open up that chest or pit down the road.

With the wide range of chemicals and compounds used in Chemical Production these days, there’s no way to use one product. You need to consider a few things before you decide what you’ll use.
Some coatings are designed for acid service while others are specifically for caustic. There are even choices for single common chemicals like sulfuric acid. This can be tough when a single containment is common to multiple processes.
This is critical. You’ll have to make your system resistant to this if you expect it to last.
You need to make sure the coating can take it or
Re-coating a secondary containment area seems to be pretty easy. I mean, it’s just paint right? Well, it may brush or roll on like paint, but chemical resistant coatings are much more. Before you jump into self-performing a coating like this, you need to consider that you might need a contractor. Here’s some things to think about.
If this going to be a simple re-application of primer and topcoat you should consider doing it yourself. Of course, there will be some prep required. But it should be easily done with the tools you have with some direction.
If the system is new and will require reinforcement at joints and transitions, you might want to get a professional to look at it.
You could probably self-perform if a grout type system is to be used if you have
You’ve chosen the right coating or lining for your project considering all of the factors. Things like operating temperature, chemicals, concentrations, expected level of protection and so on. Once this system is in place, you or your customer will have just the protection needed to protect critical plant infrastructure.
Now it’s on to make sure the system you’ve chosen will stay in place. It needs to bond to the concrete and stay there. You’ll need to prepare the concrete to present the best possible surface for the coating or lining. Sounds easy. But, the surface you have to adhere to is often not smooth or uniform. Given the fact that you need a protective system at all, it’s probably not in the best of shape. The concrete may be deteriorating, damaged and contaminated and have to be repaired to
Proper dust collection systems for mixing operations are important not only for the health and safety of your crew, but also the health of your business. If you fail to meet the OSHA standards, you could receive a serious and extremely costly violation.
Workers who are exposed to respirable crystalline silica dust are at increased risk of developing serious silica-related diseases. OSHA’s standard requires employers to take steps to protect workers from exposure to respirable crystalline silica.
