Long length solid wall HDPE Pipes

Small to large diameter pipes delivered in long lengths from Pipelife Norway

 

Pipelife draws on more than 25 years of experience in the design, production, marine delivery and installation of long length large diameter HDPE pipe systems. Our solid wall pipe systems are made of PE 100 high density polyethylene and are produced to international and national standards and norms in Stathelle, Norway.

The pipe diameters we deliver range from very small to 2500 mm. The pipes are, moreover, seamlessly extruded to lengths of about 600 meters. Lengths up to 2.5 kilometers and more can be achieved with smaller diameters.

Our products' sturdy material, extra long lengths and broad range of diameters make our pipe systems a perfect match for onshore, near- and offshore solutions serving mainly but not exclusively:

  • power plants
  • desalination
  • water and wastewater applications
  • transmission line protection (e.g. offshore windfarms)

Like all our products, they are produced to strict international and national standards and norms. For more information on standards and norms please take a look at our technical brochure.

Your benefits with long length HDPE Pipes

  • Little to no welding work
  • Minimized risk of joint failures 
  • Lower transportation costs
  • Substantial time and cost savings for the contractor (e.g. no land based site and storage area necessary)
  • Lower risk for damages during handling, transport and storage

Delivery of LLLD HDPE pipes

Kilometers of HDPE pipes have been economically delivered by tug boat to over 140 different marine sites around the world. They are towed from the Pipelife plant in Stathelle, Norway, directly to the (marine) installation site where they are ballasted, submerged and installed.

Economic, simple and direct: No transshipment, no onshore storage needed.  

Delivered to almost every corner of the world: Pipelife has a long track record of HDPE pipe deliveries to lots countries around the world including Uruguay, Ghana and even Malaysia. 

Wide range of installation and jointing methods

After the delivery by towing the pipes across the sea, the installation can be conducted, using several methods, depending on the preconditions:

Offshore Installation

  • S-Bend installation (ballasting, trenching/backfilling - practiced since the 1950s)
  • Directional drilling (pulling pipe direction land)

Onshore installation

  • Above the ground
  • Open trench
  • Pipe bursting

Jointing Methods

Pipelife delivers a complete system from fixed point to fixed point, onshore and offshore, including fittings and jointing. Pipelife uses electrofusion saddles or conventional fittings made from PE 100. To fit every project, our HDPE pipes can be jointed using several methods:

  • Electrofusion welding
  • Butt fusion welding
  • Extrusion welding
  • Saddle welding

Our whole production is certified to EN12201 and has to withstand hydrostatic pressure tests and elongation break tests. You can find more informations about quality testing in our technical brochure.

HDPE Pipes: Case Studies and Videos

Three 350-m-long, large diameter HDPE Pipes travel the Atlantic to be sunk in the Caribbean

Three 350-meter-long, solid wall, so-called LLLD (long length large diameter) Pipes travelled all the way from Norway over the Atlantic Ocean to Punta Catalina power station in the Dominican Republic, where they serve as cooling water lines.

New World Record with a 3.3 km HDPE Pipe Delivery to Malaysia

Pipelife has set a world record after towing over 3.3 kilometers of pipe from Stathelle, Norway, to Malaysia. The long length large diameter (LLLD) HDPE pipe delivery to a major power project was towed for unrivalled 27,720 kilometers.
