Electrofusion Joining Procedures for Flex Restraints
(for use with Ratchet Strap Clamp )
(1) Identify the desired location for the Flex Restraints
(2) Pipe must be clean. Remove all sources of
contamination. A minimum 70% concentration of
Isopropyl Alcohol and a lint free rag should be used
to clean the surface area to be fused.
(3) For the purpose of insuring a good scrape of the
fusion area, use an appropriate marker to randomly
mark over the outlined fusion area. This will provide
a visual gage while scraping.
(4) A thin layer of the pipe surface area must be
removed in the area that is to be fused in order to
assure a quality fusion joint. (Do not use emory
cloth - see “Proper Pipe Preparation” page 3) Scrape
the fusion area until all of the marks have been
removed.
NOTE:
Make sure the fusion area remains clean and free of moisture
during the installation of the saddle. If contamination of the
area occurs after scraping, Isopropyl alcohol should be used
to removed contamination. Re-scrape if necessary
(5) The Flex Restraint must be secured to the
scraped area of the pipe surface. This can be ac-
complished in a variety of ways (i.e. wormgear
clamps, c-clamps or nylon ratchet straps), ratchet
straps are the recommended application tool due to
the ease of use.
