Had a great time exhibiting at the 2014 PNWS-AWWA Conference in Eugene, Oregon this past week. Was yet again another fantastic conference. More than happy to help support such an active section and to have the chance to meet so many users of our products.

The Importance of Injection Quills

The photos below highlight one of the most important reasons to use an injection quill.  A water treatment plant design did not include injection quills for dosing caustic.  Instead, the chemical was directly fed into the taps on the saddles.  It was only a matter of time until the caustic corroded out the main resulting in a rupture.  A properly specified injection quill avoids this issue by delivering the chemical to center of the main, away from the interior sidewall.  

People unfamiliar with injection quills can feel a bit overwhelmed by the questions we ask when working to identify the right quill for their application.  But taking the time up front can help to eliminate costly repairs down the road.

A little over a year left until the the new lead regulations go into effect nationwide.  Being in California we've been offering No-Lead options since it was implemented here in 2010.  The article doesn't mention it but Louisiana was set to go 'no-lead' on January 1, 2013.

4 Basic Parts of a Retractable Injection Assembly – Part 2 of 2

Last week we discussed the first two parts of a retractable injection quill: the Main Connection Valve and the Compression Gland.  This week we’ll take a look at the other two parts: the Solution Tube (Quill) and the Restraint System.

Solution Tube

The solution tube is the part of the injection assembly that actually conveys the chemical into the water main.  The discharge end passes through the main connection assembly down into the process main where the chemical is injected into the process flow.  Since this is the ‘business end’ of the assembly there are quite a few things that come into play.  Each is a long discussion on it’s own, so for now we’ll just list the out some major ones to give you an idea:

- Material Compatibility
- Chemical feed rate
- Insertion length required
- Process main velocity
- Temperature
- Features (tip configurations, check valves, etc.)

Restraint System

The restraint system may not be the first thing you consider when looking at a quill – but it should be.  Injection quills operate under pressure from the main.  If there is not an adequate restraint you risk the quill ‘blowing out’ which could result in a release of process fluid, chemical spill, or more importantly, injury to anyone in the vicinity.  
There are many types of restraint systems available on the market.  At SAF-T-FLO we utilize three types depending on the product - 100psi, 150psi, and 250psi rated versions.  The 100psi and 150psi versions utilize two chains, the restraint chain and the limit chain.  The restraint chain connects to what we term the restraint hook and locks the quill in its operating position.  The limit chain serves as a secondary restraint and limits the quill from extending past the compression gland while at the same time allowing it to clear the ball valve so that the main connection valve can be closed.
The 250psi version uses our Dual Bolt restraint to lock the quill into the operating position.  It consists of two plates – one on the main connection valve and one on the quill that are bolted together with connecting bolts when the quill is in operation.  For insertion and removal there are two limit chains that serve the same purpose as described above for the 100psi and 150psi versions.

Summary

Retractable injection quills are a critical part of many chemical dosing applications.  They are involved in the application of potentially hazardous chemicals to a pressurized main and deserve to be respected and understood so that operators can ensure the long and safe service life of their treatment plan.
