Tank Blanketing: A Look Into Nitrogen Blankets

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.

Using Baffles for Tank Mixing Applications

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.

Explained: Sulfuric Acid Storage Policy

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

The Security Benefits of Bellows Transition Fitting

We have all heard the adage, “if a job is worth doing, it’s worth doing right”. Poly Processing believes this to be true 110% of the time when it comes to containment. Every single piece of a tank system needs to be completely secure to protect your workspace, your employees, the environment and the chemical being stored.

An Inside Look At On-Site Tank Inspection & Testing

When storing any type of chemical, it is important to conduct routine inspections to make sure the tanks, fittings, venting, and accessories are in good working condition. It is possible to perform some of the tank inspection on your own, but periodically, the system should be checked by a Field Service Representative.

Judging the Performance of a Polyethylene Tank

There are many things to know and consider that will help you extend the life of your tank to its fullest potential. It is important to know that from the production of the tank, through installation, it is expertly manufactured with all of the right gaskets and fittings. After tank installation, it is important to have it inspected regularly to look for problems that could cause tank failure.

The Role of Chemical Temperatures in XLPE Chemical Storage

When considering chemical tank design, it is vital to consider the chemical you’re storing first. That tells the manufacturer what material to use, what types of fittings and accessories are needed, and whether or not the tank needs an antioxidant layer or other special considerations. It is equally important to have an upfront understanding of what processing temperatures are needed for the chemical, because that, too, helps the manufacturer design the best tank for your chemical storage application.

Environmental Stress Cracking in Rotomolded Polyethylene Tanks

Environmental stress cracking is the term used to describe the microscopic cracks that occur to polyethylene as a result of storing chemicals. Over time, the smaller cracks combine to form large cracks, which can result in leaks or even tank failure. The polyethylene’s resistance to these cracks is what is known as environmental stress crack resistance (ESCR).

Flexible Connections: The Do’s and Don’ts

The placement of appropriate flexible connectors will not only help ensure a tank’s longevity, but can also protect the tank from hinge points that can cause dangerous leaks.

Let’s take a closer look at flexible connections, specifically how they should and should not be used and installed.
