WELDING SERVICES

We offer on-site welding services of all polyethylene pipeline systems up to 2500 mm diameter. For over a decade, we have been the leading company in this field and carried out large numbers of projects in Egypt.

With the cooperation of October for Plastic pipes we are continuously involved with our customers supplying them with after sales technical assistance and support.

Connection by this welding method can be applied to diameter of between 50 mm and 1600 mm; and in relation to the diameter, to wall thicknesses from 5 mm to 100 mm.

The ends of the two pipes to be welded are secured by the clamps of the welding machine. The end of the loose pipe or the pipe to be added to the pipeline should be placed in the movable hydraulic part of the machine.

Secure the longitudinal movement of the free pipe by using adjustable rollers.

Prior to welding process, welding surfaces must be scraped (using the planer) by fixing it between the two ends to be welded; any oxidation removed and the welding surfaces must come into complete contact.

Once the welding surface has been scraped, it must be protected from dirt and the pipe ends need to be cleaned. If there is any re-soiling, the scraping process must be repeated.

Fix the heating element, (temperature 200°C – 220°C), between the two pipe ends, keep the same hydraulic pressure for the duration of the heating up time, and then remove the heating element within a time frame equal to the release time.

PRESSURE RATING

HDPE (PE100) has a MRS of 10 MPa. The hydrostatic Design stress for the material is determined by applying a safety factor of 1.25. The design life for the water industry requires a minimum life of 50 years, therefore the design stress for PE 100 is ( 8 MPa ). Polyethylene pipe pressure ratings are generally referred to in bar; 1 bar is approximately equivalent to 10.2 meter head.
