PE Offshore Piping Systems

Jain PE piping systems have been increasingly used for various marine applications such as in seawater desalination plant’s intake & outfall pipelines, effluent disposal outfalls pipelines. Immunity to galvanic corrosion is a major reason for selecting a PE piping system. The combination of air and water; particularly seawater can be very corrosive to conventional metal pipes. Whereas PE pipes are best suited for seawater intake and outfall pipelines because of its flexibility, stronger joints and inertness to seawater.

Apart from the above, other beneficial features like light weigh, floatation properties, integral joints stronger than the pipe, flexibility of the pipe, convenient short cold bending radius, adequate Ring Stiffness, strain-ability due to PE’s high strain capacity, adjustment capacity to various external forces generated by wave and current action of the sea, ocean, river or lake water bodies under which the pipes are to be installed and also the high strain capacity which allows the PE pipes to safely shift or bend to accommodate itself to altered bedding which is the result of under-scouring that may sometime occur due to strong wave and current action under water.

The integral joints with high tensile strength have also made it possible to use the pipes for installation under water bodies by using Horizontal Directional Drilling (HDD) method.

Jain PE pipes of larger diameters ranging from 800mm to 2000mm outer diameter have been used in India for the applications mentioned below. So far 220 km of JAIN PE pipes of above size range have been used all over India for marine installations since the year 2000, and working successfully without any complaints from the end user Industry.

When PE effluent outfall lines which start from user Industry towards the sea, the route from the Industry to the LandFall Point (LFP) is installed on land either above ground or underground.
