Reality Construction Site



Wrong preperation



Missing inspection of thedelivered Pipe Material



Dangerous Pipe Storage



Wrong Pipe Storage (ovality)



Wrong Pipe Storage (damages)



Wrong handling of HDPE Pipes



Wrong laying of HDPE Pipes



Terrible bedding of HDPE Pipes



Bad alignment of HDPE Pipes



Current SituationMiddle East

Reasons:

Existing Standards needs to be more specific

Strict enforcement of Standards throughsupervision needs to be improved

Contractors are not specialized/certified

Welders are not trained/certified

Article, AUG 20, 2011 AME Info – The ultimate middle east business resourceGCC states must address water shortage issues as populations soar

Water has always been a valuable commodity in the desert. But today, with Gulf nations boasting robust population growth and ever-soaring demand for utilities, governments must act immediately to ensure that water shortages don't become a regular occurrence across the region. …Per capita water consumption in the GCC is already the highest in the world, with Abu Dhabi leading the charge with the average resident consuming 550 litres each day. … does not include water used for agriculture and landscaping….

It has been estimated that leaking pipes account for up to 50% of the water loss in some parts of the region - an alarming statistic when you consider that a great deal of the Gulf's infrastructure is just a few decades old.…"An important element is to significantly reduce the amount of water lost from the distribution network…

…estimated that leaking pipes account for up to 50 % of the

water loss in some parts of the region… an alarming statistic …the Gulf's infrastructure is just a

few decades old.

Training Centre|UAE



BASIC Training

Certified HDPE Pipe Welder GW330 (5 days)

ADVANCED TrainingCertified HDPE Pipe Welding Supervisor GW331 (5 days)

EXTENDED ExaminationGW330 / GW331 (Re-fresher courses 1 day)

Systematic Training Program



The new Training Centre in Dubai is a fully equipped facility that offers theoretical courses covering various topics related to plastics, as well as a state of the art welding work shop, providing you with practical training and hands-on experience in welding and testing techniques for pipes and plastic products.



The training program is specially designed for engineers and consultants involved in the design, specifications and supervision of plastic pipeline projects, site supervisors responsible for monitoring onsite welding activities and welding technicians performing onsite welding and installation of HDPE pipe networks.
