Marina Utilities is a leader in providing quality marina utility systems and in meeting the stringent ecological requirements for Clean Marinas™ and eco-marinas in Florida, the US and worldwide.

Marina Utilities uses superior HDPE piping and 316 stainless steel components in its marina systems, providing leak-proof and corrosion-free piping systems lasting 20 – 30 years in a harsh marine/marina environment. Such exceptional marina utility components are key in preventing failure, leakage, pollution and in protecting pristine marina waterways.

What happens to lesser quality components and connections in the marine environment? Typically, glued non-stainless steel transitional fittings, threads and metal components corrode, causing gaps and system leaks. Connections, joints and non HDPE piping can leak because the glue was not applied uniformly, or as piping and connections are subjected to natural water or weather related movement.

HDPE piping systems are leak-proof because of the manner in which they are joined. Rather than a glued-together connection system such as is used with PVC pipe, the two surfaces of HDPE pipe are heated to a designated temperature and then are fused together by application of force. This pressure causes flow of the melted materials, which causes mixing and fusion.

HDPE pipe systems are fluid and seamless. When the polyethylene material is heated, the molecular structure is transformed from a crystalline state into an amorphous condition. When fusion pressure is applied, the molecules from each polyethylene part mix. As the joint cools, the molecules return to their crystalline form, the original interfaces are gone, and the two pipes become one homogeneous unit.

Marina Utilities’ technical expertise in the process of fusion includes:

  • Clamping: proper preparation and clamping of pipe pieces as they are held axially;
  • Cleaning of pipe and fitting contact points;
  • Facing: where the pipe ends are positioned to establish clean, parallel mating surfaces perpendicular to the centerline of the pipes;
  • Aligning: where the pipe ends are aligned with each other to minimize the mismatch or high-low of the pipe wall;
  • Heating: where the melt pattern that penetrates into the pipe must be formed around both pipe ends;
  • Joining: where the melt patterns must be joined with a specified force that must be constant around the interface area;
  • Holding: where the molten joint must be held immobile with a specified force until adequately cooled.
