Birch Vale, UK -- Dow Hyperlast says it has developed equipment to blend glass syntactic polyurethane (GSPU) coating and insulation systems for deep-water pipelines on site in remote locations.
A new Etnaflow Portable Mixing Plant from Dow Hyperlast, part of Dow Polyurethane Systems, allows for safe and efficient mixing of materials, the company claims. Meanwhile, advanced process control "ensures formulation accuracy and the quality and consistency of the finished product." Dow Hyperlast said.
"The Etnaflow mixing system was inspired and developed as a direct result of our requirement to supply Wasco Coatings in Malaysia, with Flow Assurance Insulation coating materials for the Gumusut-Kakap project," said Alex Lane, global business leader for Dow Hyperlast's Pipe and Tank Division, in the company's 4 May announcement.
According to the company, Etnaflow requires fewer human and capital resources to operate, and eliminates the "enormous storage and disposal requirements of conventional GSPU mixing systems."
Its closed-loop design also minimises the potential for chemical exposure or injury to workers from moving machinery, the company added.
For the Gumusut-Kakap project in the South China Sea, the materials needed to perform well at ocean depths of up to 1200 m, "in very remote areas," said Lane. The work needed a reliable, portable GSPU mixing system, and Dow's experts came up with the Etnaflow. This consists of raw materials holding and dosing units, plus a blending operation where the polyurethane and the glass micro spheres are mixed.
Dow Hyperlast said it can ship the unit to a customer's site, provide set up, training, remote monitoring, and ongoing technical support, with installation and training completed in as little as two weeks.
Wasco Coatings started working with Dow Hyperlast over a year ago; "we probably wouldn't be coating it today if it weren't for that relationship," said Kevin Revere, general manager of Wasco Coatings. "We were able to go in with our engineers, design the equipment around our specifications and around our needs, and find ways to streamline the job and maximise profitability."
