This research carries how to do steel pipelines defects repair process by a simple and
easy way. At first the region that surrounds the defect is cleaned then the epoxy material is
put over the defect after mixing the resin with the hardener well.
Epoxy layer dimensions
depend on the defect dimensions that exists in the pipe. After that, the specimen is released
for a period of time to obtain the setting process. Several types of epoxy were used for
preparing series of specimens, which were tested on the pressure set up to estimate the
efficiency of this way in the repair, and knowing the pressure values that epoxy layer can
carry. A pipe of three holes their radius are equal, was treated by using ALTECO QUICK
EPOXY STEEL and the pressure gauge recorded many values that reached 18 bar. The
curve, that represents the relationship between the pressure which the epoxy layer carried
and its surface area, was drawn. It is found that the most effect factor in the repair process
is the specimen preparing and the thickness of the epoxy layer.
This paper provides a major challenge, Because of many
bad conditions that effect oil pipelines properties, this paper
discuss the ability of manufacturing and applying the 3D
woven spacer composite fabric for insulating oil pipelines.
This paper
talks over the thermal, chemical, and mechanical
properties of the final product from the 3D Spacer Fabric and
the polymer resin matrix.
And finally, this paper gives an idea how and with any kind of
weaving machines these fabrics can be made.
