Description / Abstract:
This practice covers requirements and test methods for
installation of a semi-structural polyethylene (PE) and
encapsulated cement mortar formed-in-place lining system (FIPLS)
intended for the rehabilitation of water pipelines from 4 in. to 12
in. This renewal process involves installing a folded PE liner with
multiple hooks on the outside face into an existing water pipeline
then pumping cement mortar into the annular space and progressively
reforming the liner against the original pipe wall by means of
forcing a reforming device through the pipeline.
The values stated in inch-pound units are to be regarded as
standard. The values given in parentheses are mathematical
conversions to SI units that are provided for information only and
are not considered standard.
This standard does not purport to address all of the safety
concerns, if any, associated with its use. It is the responsibility
of the user of this standard to establish appropriate safety and
health practices and determine the applicability of regulatory
limitations prior to use. Particular attention is drawn to those
safety regulations and requirements involving entering into and
working in confined spaces.
This practice is to be used with the material specified in 4.2.1
of F2718 the Standard Specification for Polyethylene (PE) and
Cement Materials for an Encapsulated Cement Mortar Formed in Place
Lining System (FIPLS) for the Rehabilitation of Water
Pipelines.
