Using a Universal Ball Dome Fitting on Your Chemical Storage Tank

Universal ball dome fittings, or UBD fittings, are a type of tank fitting that has a moveable ball inside to allow angular adjustments. UBD fittings can only be installed on the dome of the chemical storage tank, because they aren’t considered leak-tight. The dome fitting has a compression nut that locks down the ball after you install the flange or bulkhead, allowing connections at angles up to 24 degrees.  The self-aligning UBD fittings can be installed on the dome of a Poly Processing storage tank to give you more options for fitting placement. UBD fittings are an excellent choice for our double-wall SAFE-Tanks®, vertical tanks, or IMFO® Tanks.  Let’s take a look at the uses for these types of fittings and their advantages.

For Full Discharge, Don’t Rely on Cone Bottom Tanks

When it comes to a full discharge tank, cone-bottom tanks get the job done—except when they don’t. The fact is, cone-bottom tanks fall short on several fronts.  Cleaning cone-bottom polyethylene tanks can be challenging. They require additional vertical space and safety precautions. And the tanks themselves cost a pretty penny — especially when you have to include a stand and basket to support the cone-bottom tank. Prices can skyrocket in today's market with the costs of metal and special coatings. Lead times for welded steel products can be extremely long as well.

NSF/ANSI/CAN 61: Potable Water vs. Chemical Certification

Poly Processing is committed to ensuring that our polyethylene chemical storage systems are NSF/ANSI/CAN 61 certified. In our previous article on NSF, we looked at NSF/ANSI/CAN 61 and what it means to be certified. There can be some confusion about whether tanks or tank systems are certified to NSF/ANSI/CAN 61 and which certification is valid for which tank.

Bulk Tank Specifications That Save Project Time and Money

Municipal projects require detailed specifications for anything purchased as a capital expense. At Poly Processing Company, we’ve teamed up with national engineering firms and municipalities to develop industry leading pre-written engineering specifications for our three most popular polyethylene chemical tanks: the SAFE-Tank®, the vertical tank with IMFO® and the upright vertical storage tank.

5 Key Differences Between Compounded and Pigmented Tank Colors

Poly Processing customers choose to color their polyethylene chemical storage tanks for a number of reasons. Tanks may be colored for aesthetics, branding, chemical identification, or to reduce transmission of radiant heat through the plastic.

How Do You Know If Your Chemical Storage Tank Is Compatible?

When you’re storing hazardous fluids such as corrosive acids, bases, or aggressively oxidizing chemicals, you need to be confident that your chemical storage tank can meet your expectations for years. You can’t afford to invest in chemical tanks, only to discover a year later that your chemical storage tank isn’t compatible with the chemicals you’re using. That’s a loss of product, time, and money—and it could put your people, equipment, and environment at risk, as well.

NSF/ANSI/CAN 61: The Basics

Most products that come in contact with potable water are tested under NSF 61 with the pH 5, pH 8 and pH 10 exposure waters that are defined in the standard. These exposure waters were designed to simulate the wide variety of potable water chemistries encountered across North America. However, the exposure waters were not designed to predict leaching of materials caused by aggressive chemicals.

Sodium Hypochlorite Storage - Reviewing Best Practices

Sodium hypochlorite is a well-known and aggressive oxidizer that is used in many applications. Our end-use customers often use “hypo” in the water treatment business to eliminate bacteria and viruses from water supplies. Anyone looking to maintain a safe and secure storage tank system has three challenges to overcome: UV rays, off-gassing, and oxidation. Over the years, Poly Processing has established a set of industry leading best practices that represent an ideal sodium hypochlorite storage system for overcoming these challenges.
