We’ve worked hard at Poly Processing to provide a comprehensive website that addresses many of your questions about harsh chemical storage. We also provide resources like walkthroughs, downloads and even tools to help you build your chemical storage system or to request a quote.
Chemical storage tanks can be equipped with a number of different fittings and accessories to improve the safety, efficiency, or ease of filling and emptying the tank.
In some chemical storage tank applications, it is necessary to install a ladder to allow for inspection, to check gauges, and to service level sensors or mixers. But what ladder options are available, and which ones are best for the chemical you’re storing?
Many industrial chemical applications involve mixing to create a different product, for wastewater treatment purposes, or to dilute the chemical. Polyethylene tanks are well-equipped to handle that type of process, as long as the chemicals being mixed can be safely combined.
One common type of valve that is appropriate for many chemical storage solutions is the ball valve. Here's how your chemical storage system can benefit from a ball valve.
When you think about a chemical storage tank system, you have to consider the factors that impact the tank’s service life. Not only do you have to make sure that the tank material and fitting materials are compatible to the chemical you are storing, it is also important to consider the functionality of the tank.
Whether you’re an engineer writing a spec for a chemical storage system, or an end user who is looking for the best way to store corrosive chemicals, there are multiple factors that go into creating a safe storage system. Cost might be the first consideration, but there is more to cost than the initial price of the tank, its fittings and accessories, delivery, and installation.
High-density polyethylene chemical storage tanks can be made of linear polyethylene, and they can be made of cross-linked polyethylene. They are both made with resins that are heated to create a cured plastic, yet the differences in their development create very different polyethylenes of structural strength.
If you’re storing an oxidizing chemical like sulfuric acid or sodium hypochlorite in a polyethylene tank, an antioxidant barrier will more than double the life of that tank.
Just as proper tank maintenance and frequent inspections help ensure that a tank lives out its projected useful life, it is equally important to install the tank properly. Here are some common questions we get regarding the installation process.
Tank blanketing is also referred to as tank padding, and it describes the process of applying an inert gas to the vapor space (or unused space) that exists above the chemical inside a storage tank. Tank blanketing is mainly used to add a layer of gas (usually nitrogen) to keep air or moisture from a chemical inside the tank.
Obviously, in a chemical storage and mixing scenario, moving the tank around like you might do with a cake mixer to get all the chemical that can’t be reached is not an option. That’s where baffles come in.
