Ionix Static Suppression Cartridges for the 
natural gas distribution lines

OVERVIEW OF OPERATION
Ionix Static Eliminators are designed to prevent static buildup and to eliminate accumulated static charges on the inside walls of PE gas distribution piping systems. Ionix will dissipate and prevent the buildup of static inside all pipe downstream of installation of the Ionix. Ionix is equally effective on both metal pipe as well as PE pipe and the presence of metal in the gas distribution system has no effect on Ionix performance.

OVERVIEW OF DESIGN CONSIDERATIONS
Treatment area
First you must decide the distribution area you wish to eliminate static. Once this is decided you must then isolate the district regulators feeding that area and install Ionix at those regulators. Ionix is ONLY effective when ALL the gas entering the distribution area you’ve chosen to treat passes through an Ionix unit. If untreated gas invades the treatment area, the effects of Ionix will be diminished or eliminated.

There is no practical limit to how far Ionix will treat your system. As long as pressure and flow limitations are observed and all regulators feeding the area have Ionix installed, Ionix will dissipate and prevent the buildup of static within the installation area.

Installation location
We recommend installing Ionix above ground at the outlet side of the regulator. The reason for this is that to install Ionix you must have a bypass available to install the Ionix in the gas stream. Since Ionix must be changed, a location above ground with a bypass already in place makes installation and maintenance easy. You can install Ionix below ground provided a bypass is available and the Ionix is changed each year.

INSTALLATION
The filter housing holds the Ionix unit inside it in the gas flow. 

To install this method the filter housing which comes with flanges is bolted directly to the outlet side of the district regulator. The outlet side of the housing would be flange bolted to the line continuing to distribution. The Ionix cartridge is installed in the housing through the top loading bolted top.

MAINTENANCE
Once the Ionix is installed, there is no maintenance other than replacing the Ionix. Remove the Ionix cartridge inside the filter housing and replace it with a new Ionix cartridge. Exhausted Ionix cartridges can be returned for a core credit provided they are in re-useable condition.

MONITORING
For the first 2 weeks of operation a monitoring program should be organized to verify proper installation and elimination of static in your system. The protocol below explains how to establish a monitoring system. Ionix will work with you to establish a system.

Any standard electrostatic voltmeter can be used to take your measurements. Since each voltmeter is different, you must follow the manufacturers instructions for using the meter.

As far downstream as possible, identify as monitoring points several locations on the system where the meter riser exits the ground to the customer’s meter. Choosing a site at the farthest point downstream and eliminating static at that point would verify static is dissipated throughout the system. Mark a point on the riser where you intend to make your readings so you read the same point each time.

Static readings need to be taken at these proposed monitoring points BEFORE the Ionix is installed into the PE distribution system. This is necessary in order to indicate the presence of static inside the pipe walls at the riser at the monitoring point you have selected. 

After taking static measurements at your selected monitoring points and verifying the presence of static at the monitoring points, install Ionix into the distribution system. After allowing a few days for Ionix to treat the entire system downstream, consistent static voltmeter readings of zero should be expected at your monitoring points.

The monitoring points should be checked twice a week for 2 weeks after installation of Ionix into the system. After 2 weeks, you can reduce or eliminate monitoring as you desire. However, Ionix recommends checking static monitoring points once a month until the 1 year replacement date. 

The procedure for measuring static is as follows. Prior to taking a static reading, use the wet rag method to dissipate the static on the OUTSIDE of the monitor point riser. This will insure that the reading you are taking are the static charges on the INSIDE wall of the riser. After drying the riser, take the static reading. Be sure to take the reading at the same point each time.
