Poly Processing

High-density cross-linked polyethylene (HDXLPE) tanks offer the structural integrity and chemical compatibility needed to support demanding agitation requirements over the tank's long service life.

Understanding your mixing options is critical to designing a storage system that performs safely and reliably from day one.

You need to know how much chemical is in your storage tank so you can order more product at the right time to continue business without missing a beat. Not only that, but certain chemicals have to be stored at specific levels to maintain their properties.

The Poly Processing Reverse Float Level Gauge makes it easy to monitor the levels in your chemical storage tanks.

Double-wall piping is a secondary containment piping system — in simple terms, a pipe within a pipe.

Many facilities design for “full containment” as a system concept. That means the tank, fittings, piping, and termination points all keep the chemical within a controlled boundary, even during a leak.

When purchasing a chemical storage tank, it can feel overwhelming to navigate the landscape of industry standards and regulatory requirements. From material testing protocols to federal safety mandates, the compliance considerations are numerous — and the stakes can be high.

This article brings together an overview of the most important compliance frameworks you need to understand: ASTM D-1998, NSF/ANSI/CAN-61, FDA, OSHA, and IBC seismic and wind restraint standards.

A hydro test verifies the structural integrity of the tank by filling it with water and checking for leaks. The test is one of the most reliable steps to perform before you begin using a Poly Processing polyethylene storage tank.

Four situations should prompt a hydro test before using your chemical storage tank.

Chemical separation inside a storage tank isn’t just an operational inconvenience; it’s a genuine threat to product quality, process efficiency, and system longevity.

Properly designed mixing and agitation systems are essential to a complete chemical storage solution, whether you’re in water treatment, municipal infrastructure, industrial manufacturing, or food and beverage processing industries.

The root cause of most tank accessibility failures is a simple sequencing error: the building is designed and built first, and the tank is ordered afterward. Chemical storage is often viewed as a secondary utility function, so it gets planned last.

When access is planned, installation proceeds smoothly and safely. When it isn’t, the consequences ripple outward in time and money.

Why Building Layout Planning Is Critical Before Your Tank Arrives Plan your facility before your tank arrives. Proper layout design prevents costly access issues, damage, and safety risks throughout the tank lifecycle.

Before you put a Poly Processing chemical storage tank into service, it’s important to conduct a hydro test so that you can commission the tank with confidence.

A hydro test verifies the structural integrity of the tank by filling it with water and checking for leaks. The test is one of the most reliable steps to perform before you begin using a Poly Processing polyethylene storage tank.

This article provides basic information about when to test, how to do it, which seals to use, and what to watch for while the tank is full.
