يهدف هذا البحث بدراسة تجريبية تحديد تلوث أنابيب البولي اتيلين بالغبار أثناء اللحام بالتقابل في ورشات تمديد الأنابيب و تأثيرها على كفاءة اللحام.
The objective of the study was to determine experimentally
the dust pollution of polyethylene pipe during head- to - head
welding in the workshops piping and its impact on the efficiency of
welding.

The aim of this research is to study the absorptive effect of high density (HDPE) polyethylene pipes for the hydrocarbon compounds on the characteristic (Force, Elongation) curves. To verify this, we immerse some parts of the pipe in different hydroc
This research seeks to localize the technology of plasma arc welding (PAW), the best
alternative against tungsten arc welding (TIG). So a quantitative comparison between these
two technologies has been made, according to the particular case that is
The corrosion of biogas pipes and equipments damage as generators, boilers and coprocessors is one of
the most real important problems in Damascus wastewater treatment plant (at Adra region). These

Clayey expansive soils are fine grained soil with a low strength. Its
swelling potential and shear strength are significantly affected by
the water content.
This research aims to study the effect of the initial water content
on both shear strength and the required displacement to reach the
maximum strength.
This research demonstrated a way to study the thermal properties
of raw and recycled High Density Polyethylene HDPE which is
used to make oil containers. Also, the research has dealt with the
effect of recycling on blow molding process used to manufacture
these containers.
