Electrofusion Joining Procedures for Sidewall/Saddle Fittings
(for use with under-clamp on 1-1/4” - 6” fitting bases)
1.) Identify the location of the fitting to be installed on the pipe and mark the
area with a non-greasy marker.
2.) Check the pipe surface for any embedded debris that may cause damage
to scraping tools making sure that the outer pipe surface is clean and free of
any dirt or mud that could recontaminate the scraped pipe surfaces.
3.) Scrape the area to be fused with an approved scraping tool. Make sure
that the appropriate amount of material is removed approx. .007” to .0010”.
Do not use abrasives, grinding wheels, or other devices that do not cleanly
remove the contaminated material.
NOTE: The purpose of scraping is to remove material from the pipe surface.
Simply roughing up the fusion area will not allow an acceptable bond to take
place. (see “Proper Pipe Preparation” page 3 )
4.) Avoid touching the scraped pipe surface or the inside of the fitting as
body oils and other contaminates can affect fusion joint performance. If the
surfaces become contaminated, clean thoroughly with a clean, lint free towel
and a minimum 70% concentration of isopropyl alcohol and allow to dry before
assembling. Do not use alcohol with any additives other than water.
CAUTION:
AVOID ALL POSSIBLE RECONTAMINATION OF THE PREPARED SURFACE.
