Pipes in concrete or plastic

Ecetas is both an infrastructure company and a pipe manufacturer. Being a contractor provides several benefits to EBS clients, such as providing extensive technical knowledge and supervisory services. Ecetas is experienced in the installation of sewage systems in unfavourable conditions. The company has wide knowledge, especially in sheet pile applications in low bearing capacity

soils where the groundwater level is relatively high.

pipes manufacturing, the company now offers to the Turkish and global markets polyethylene pipes (PE100, PE80, PE63, PE80 gas, steel wire reinforced thermoplastic PE100, corrugated, metal reinforced polyethylene) and GRP (glass fibre reinforced polyester) pipes and fittings, manufactured under the EBS (ECE Pipe Systems) brand. The manufacturing plant in Manisa consists of a 7,500m 2 covered area and 50,000m 2 open area, including the stock yard. Additional factory locations are under construction for undergoing new investments. New pipe manufacturing machinery in Manisa will broaden the EBS product portfolio, resulting in an increased capacity in plastic pipe manufacturing. Ecetas Insaat Sanayi ve Ticaret AS – Turkey ecetas@ecegrup.com.tr www.ecegrup.com.tr Excel has proven to withstand the heavy loads associated with directional drilling. In total 660m of butt-fused 500mm pipe in SDR17 and SDR 11 was supplied to complete the work. With the watercourse left undisturbed and less disruption to visitors, the work was completed within the planned timescales and all parties were satisfied with the outcome. Installed by open-cut in the ‘dry’ sections of the pipework, Excel reduced the installation time through its ability to be ‘snaked’ into the trenches, as flexible pipe strings welded from multiple 12m lengths. The directional drilling method also saved time. The new £2.3 million pipeline forms part of the wider £390mn five-year infrastructure programme by South East Water to secure future water supplies. Its completion will see an extra 2.5mn litres of water transferred from a nearby water treatment works into Maidenhead’s water supply network.

Beyatas (Beton Yapı Elemanları Sanayi ve Ticaret AS), a sister company of Ecetas, produces concrete and reinforced concrete pipes and fittings in a variety of diameters and ready mixed concrete in compliance with national and international codes, in its factories in Manisa and Adapazarı, Turkey.

Pipes from Ecetas

Derived from extensive pipe manufacturing expertise with its two concrete pipe manufacturing plants, Ecetas Construction Industry Incorporated has been servicing the infrastructure industry for more than 25 years. With new investments in state- of-the-art machinery in various types of plastic

Directional drilling for new water pipeline

The installation of a new water pipeline at the heart of Maidenhead Town Moor, England, called for zero environmental and social impact. The use of polyethylene pipes from GPS PE Pipe Systems enabled this aim to be achieved. Rich with wildlife, popular with visitors and close to the town centre, the site presented a challenge to the contractor Clancy Docwra. Not only did it have to minimise impact on the surrounding area, it also had to return the Moor to its recreational use as quickly as possible, in time for a major public event in August.

As the pipeline had to cross the Moor’s waterside in three areas, directional drilling was chosen as the optimal technique to prevent disturbance to its wetland habitat and species. Minimal disturbance is achieved by digging a pit at each end of the pipe section and boring horizontally underground with a removable drill head matched to soil conditions and a series of drill stems to push and rotate the head. The head of the tool is steered from one pit to the other using a mobile transmitter. Once the pilot bore is completed, a reamer is attached to the drill stem and pulled back, enlarging the bore to accommodate the pipe that is subsequently pulled into place. Pipes used in directional drilling must meet exceptional demands, as they may be pulled through underground tunnels over considerable distances. South East Water took advantage of Excel ® high performance polyethylene (HPPE) pipe manufactured by Cambridgeshire- based GPS PE Pipe Systems. With its resistance to rapid crack propagation, long term stress cracking and corrosion,
