Understanding Chemical Injection Tanks
Chemical injection tanks are a specialized product set designed to provide secure chemical storage and precise dispensing capabilities. These systems typically include three main components: a horizontal leg tank, an elevated tank stand, and a covered spill containment basin. Together, these ensure the stability and safe handling of liquids for chemical injection systems. The tanks are intended to be used with pumps and regulators to introduce chemicals in measured amounts to achieve specific process goals and optimization.
Built from high density virgin polyethylene resin (HDPE) and rotational mold manufacturing, these tanks are seamless, resilient, and reliable. HDPE material’s natural resistance to impacts, chemical and environmental corrosion as well as temperature extremes, combined with UV inhibitors, makes these tanks suitable for year round indoor and outdoor use. Additionally, the tanks are made from FDA approved materials and can safely store potable water if needed.
A typical chemical injection system works by drawing chemicals from the tank, measured by a pump, and injecting them into pipelines, equipment, or other systems through the use of pipes or hoses and various fittings. For example, in oil and gas applications, chemical injection tanks introduce corrosion inhibitors to extend the lifespan of pipelines. Similarly, water treatment facilities rely on these tanks to dispense disinfectants like chlorine for consistent water quality. Their ability to provide precise operation minimizes chemical waste, supports regulatory compliance, and improves overall stability.
Parts of a Chemical Injection Tank
The Tank
At the core is the horizontal leg tank, rotationally molded from high density virgin polyethylene resin. This seamless design provides strength and eliminates common vulnerabilities from weak joints. The tanks are a transparent white color with gallon indicators for easy monitoring of liquid levels. As leg tanks, they have molded-in legs that provide free-standing stability.
The Stand
Chemical injection tank kits, like those offered by the National Tank Outlet, come with a tank stand. This sturdy tank stand supports the horizontal leg tank and elevates it above the ground to allow gravity-driven fluid flow and improve visibility. Additional steel support bands can be purchased to firmly secure and mount the tank to the stand if tipping or movement is a concern.
Injection Pump
The pump serves as the engine of a chemical injection system, controlling the flow and pressure of the chemicals. Pumps allow precise dosing that can be tailored to an operation’s needs. Injection pumps can often be adjusted to deliver exact volumes, allowing direct management and control of fluid flow and delivery.
Note, our chemical injection tanks do not come standard with an injection pump. For a wide selection of liquid pumps, we recommend the company Sprayer’s Supplies and their extensive catalog.
Containment Basin
The covered containment basin is a critical feature that safeguards against spills and environmental contamination. Designed to accommodate the tank’s size, the spill basin prevents debris and wildlife from being able to access any chemicals that may have leaked from connections.
Accessories
Tubing, pipes, valves, fittings, and monitoring devices complete the system by directing chemicals from the tank to the injection site. Optional fittings, such as the 316SS bolted fitting with MNPT nipple and XLPE gasket, and others are available to complete connections to the tank.
Monitoring systems such as level sensors can track chemical usage, levels, and flow rates to ensure accurate dosing, prevent waste, and alert when refilling is needed.
