SUPERLIT e-bulletin 2014 - Release #: 1
World’s largest GRP Pipe (DN 4000) installed in the sea is produced by Superlit
All GRP pipes and GRP fittings used in Iskenderun – Atlas Thermal Power Plant Project are supplied by Superlit Pipe Industries Inc. Piping for the project consists of three main sections.
- Pressure Pipeline
- Return Pipeline – Onshore
- Return pipeline – Offshore
1- Pressure
Pressure Pipeline consists of DN3200 GRP pipes as 2 lines. Pressure class of the pipe is PN10, Stiffness class is SN 5000.Cooling water is taken from the sea with channel, is transferred to the GRP pipes with centrifugal pumps(4 pieces) that is in the pump station.
Pressure Pipeline starts with the bifurcation pipe. There are fittings (5-6 meter and consists of 3 parts) between pump and bifurcation pipe, are required made from GRP.This part is not clear,yet. Furthermore, in the system, air compressors are designed to reduce excessive pressure and vacuum caused by water hammers. GRP tee pieces designed for connection to air compressors.
DN 3200 pipes of Pressure Pipeline finish in both of lines with a bifurcation part that has a pair of DN2400 outlets(Tee with a pair of outlet.) It is connected to the building with DN 2400 F Pieces.(4 pieces). There are Tee pieces with DN350 outlet and DN600 outlet before F pieces to take water by main constractor(China).
2- Dönüş Hattı Kara Kısmı
After the cycle, water is getting hotter. Heated water is transferred to the sea with GRP pipes. Return Pipeline-Onshore consists of two sections as type of pipe. First of all, return water enters from condenser inlet to the siphon wells with the pipes that classes are DN 2400,PN 4, SN 5000. This part is lower as quantity . (The sum of 4 lines is around 90 meters.) There are DN2400 F pieces in the building outlet ; there are GRP pipes with puddle in the siphon inlet,too. Furthermore,there are tee pieces with DN 350 and DN 600 outlets like DN 2400 Pressure Pipelines to take water by main constractor.
There are two siphon wells. Two pipes with DN 2400 enters to the each siphon well and comes out with one pipe DN 3400. Pressure class and stiffness class of DN 3400 pipe is PN 4 and SN 5000. Parallel two DN 3400 pipes follow a line which is around 870 meter (1740 mt totally) At the end DN 3400 pipes connected to the deep sea water discharge basin and after this level offshore piping starts.
3- Dönüş Hattı Deniz Kısmı
The outlet diameter is DN 4000 from the deep sea water discharge basin. The length of the DN 4000 line is 750 meters into the sea with pipes that classes are PN 4 and SN 5000. 6 outlets (DN 2200) is taken from the end of the DN 4000 line and 7 diffuser pipes come out from each DN 2200 pipe. Dimensional class of the diffuser pipe is DN 800. (There are 42 pieces of DN 800 outlet.)
4- Installation under water is very easy with SUPERLIT MARINE LUG …
In first time, SUPERLIT MARINE LUG (developed and took patent by SUPERLĐT engineers) was used in that project , It provided easiness and momentum to the installation under the sea.
- Superlit Marine LUG – GRP Pipe Installation under the sea
Superlit GRP pipes and fittings are used in one of the biggest infrastructure projects of Russian history.
Superlit has the honor of completing the biggest infrastructure project for potable water in history of Russia – Kalmyck Potable Water Pipeline. There was completed the main pipelines with DN 600 and DN 700 which goal is to provide quality and clean potable water to the region of Kalmyck Republic and South Region of Russia. Improving of the level of life with coverage of thousands kilometers square. The project was completed with on time delivery of products with internationally approved quality standards. Superlit will continue to be a partner and main supplier in water sector in Russia and especially in regions with serious water problems as South Russia.Superlit is continuing to be
