Polyethylene Tank Heating Systems and Insulation - Frequently Asked Questions

Maintaining the proper temperature of a chemical is often critical to safe storage. For example, sodium hydroxide at a 50% concentration will start to crystallize at or below temperatures of 60 degrees F. With polyethylene tanks, heating pads and insulation can maintain the specific temperature of the chemical you’re storing—even when your chemical tank is exposed to low air temperatures.

Explained: Sulfuric Acid Storage Requirements

Sulfuric acid is one of the most widely used chemicals in the United States. More sulfuric acid is produced every year than any other chemical. It has a multitude of industry-specific uses, such as the production of other chemicals, dyes and pigments, water treatment and fertilizers.

This heavy, corrosive chemical requires a specifically designed storage system. That’s why Poly Processing follows engineered guidelines that ensure safety and enhanced tank life.

How to Keep Your Chemicals Cool When the Heat Is On

With some chemicals, it’s critical to keep them cool because they will lose their concentration when they heat up. Sodium Hypochlorite is a prime example of that. As it heats up, it starts to lose its strength, and it begins to release gas and free radicals. Its strength can diminish dramatically with heat and UV.

So it’s important to keep the chemical as cool as possible from the moment it arrives at your facility. Other chemicals are similar—if they become too warm, they won’t perform as well as you need them to.

What Do You Need for an Effective Clean-in-Place System?

Clean-in-place (CIP) systems are becoming more and more popular in the food manufacturing industry. The system design makes cleaning the interior surfaces of a storage tank and the lines going out of it more effective and efficient without having to enter the tank. They also allow for a thorough cleaning with less exposure to harmful chemicals or contamination of food and beverage mixtures.

Many hazardous situations are safer because of CIP systems, but they require certain considerations to be effective. Let’s look at how to make your clean-in-place system most effective.

A Clear and Simple Guide to Annual Storage Tank Inspections

No matter what chemicals you’re storing, it’s important to conduct routine annual storage tank inspections. These inspections are vital to keep the chemical tanks, fittings, venting and accessories in good working condition—and to avoid costly surprise failures. Even if the polyethylene tank is relatively new, a routine and careful visual inspection is recommended.
