Why CHEMIKLER is better under the sea

Why CHEMIKLER is better under the sea

Engineers of a coastal power plant in Asia wanted to use seawater as a cooling agent.

Their design called for a 600M long pipe that would be laid out at 10M below water. The right pipe needed to have a high crushing load, as it would be kept laying at the sea bottom with sand bags. It should also be able to stand up to 5 PPM of chlorine mixed with sea water.This is necessary to kill any living marine organisms so as to limit the scaling and clogging of pipes and other equipment (particularly heat exchangers) that would otherwise be caused by the growth of algae and shellfish.

To find the right pipe, they called Trelleborg. Initially, they specified a 125 mm diameter hose, but Trelleborg experts explained that 100mm would be better for resisting the weight of the sandbags. They also advised them to consider the CHEMIKLER EPDM, a hose that proved to stand up to the harshness of chlorine transfer. It was also manufactured in 40m lengths, with specially crimped-on flanged fittings designed to prevent any infiltration.

They found CHEMIKLER hose was also easier to install than fiber-reinforced pipes. The CHEMIKLER hoses could be connected above water, reducing the amount of expensive diving time required. The total cost savings made the all-in cost of the CHEMIKLER hose much lower than the initially cheaper plastic pipe.
