HDPE Pipe for Offshore Pipeline

Piping made from polyethylene is a cost effective solution for a broad range of piping problems in municipal, industrial, marine, mining, landfill, duct and agricultural applications. It has been tested and proven effective for above ground, sur face, buried, sliplined, floating, and sub-sur face marine applications. 

High-density polyethylene pipe (HDPE) can carry potable water, wastewater, slurries, chemicals, hazardeous wastes, and compressed gases. In fact, polyethylene pipe has a long and distinguished history of service to the gas, oil, mining and other industries. It has the lowest repair frequency per mile of pipe per year compared with all other pressure pipe materials used for urban gas distribution. 

Polyethylene is strong, extremely tough and very durable. Whether you’re looking for long service, trouble-free installation, fle xibility, resistance to chemicals or a myriad of other features, high-density polyethylene pipe will meet all your requirements.

Consider the following features of HDPE pipe:

• Flexible HDPE pipeline is very suitable for soils with poor bearing capacity. 
• Favorable HDPE rheology properties (strainability and stress relaxation property) are very welcome in marine conditions and poor soil settings. 
• Unlike metal and composite material pipes, homogeneity of the pipe wall structure enables long-life in marine applications, with no corrosion and/or material deterioration problems. 
• Minor pipe damages (scratches) that can be expected to occur in installation phase are normally of no importance for the operational quality of the product. 
• HDPE has excellent abrasion resistance properties. 
• Hydraulically, long HDPE pipe strings represent the smoothest possible solution, both in terms of the pipe wall roughness and pipeline bore hydraulic properties. 
• Simplicity of HDPE pipe bedding design and trench backfill solution. 
• Proven high resistance of HDPE against seismic impacts.
