Maritime/Ship Pipe Rehabilitation
Restore maritime sewer, potable and cooling pipes.
Maritime vessels experience the same internal pipe corrosion as physical structures on land. Ships have sewer plumbing systems, cooling plumbing systems, potable water lines and fire suppression systems. These pipes are typically made of aluminum, steel or cupronickel. Our various patented technologies have been used by the US Navy to rehabilitate their ships and has also been used extensively on privately owned yachts.
Ship Sewer Pipe Lining By CIPP
Cast Iron Ship Sewer Pipes Restored With 100 Year Pipe Lining
Sewer pipes in ships are usually rehabilitated using Cured In Place Pipe (CIPP) lining. First the ship sewer pipes are cleaned thoroughly using a high pressure water jetter, or if the pipes are too badly corroded, then they are cleaned using mechanical brushing techniques. Next a pipe video inspection is made to determine the exact length of pipe that is to be re-lined, and an exact length of tubular pipe lining “sock” (liner) is cut to the right size.
The pipe liner is then saturated by an epoxy resin, which either cures ambiently within hours, or is cured using hot water or steam. The new pipe within the old pipe which is typically 3mm-6mm thick only reduces internal diameter by 5%. This pipe lining material is designed to be a stand alone pipe in the event that there are missing sections of ship sewer pipe.
Ship Potable Water, Fire Suppression and Cooling System Epoxy Pipe Lining
Corroded Ship Potable Water, Fire Suppression or Cooling System Pipes Are First Cleaned
In general, these three water systems are all rehabilitated by applying an epoxy coating. First the pipes are dried with hot air and then cleaned using high air pressure and high air flow to blow sand or silica particles through the corroded or scaled pipes. This “sand blasting” leaves a clean pipe which is ready to be epoxy coated.
Patented Inert Food Grade Epoxy Uniformly Coats The Inside Of The Ship's Pipes
Next a special patented NSF 61 approved food grade epoxy is blown through the pipes and cured using heat. Then the pipes are pressure tested and put back into service.
