Description
The requirement to locate a number of riser pipes within a caisson has always presented pipeline engineers with problems.
The increasing use of fully coated and thermally insulated riser pipes raises the question as to how to prevent or reduce the risk of damaging these coatings as the risers expand and contract during their operational life. Traditional fabricated steel centraliser clamps have proved difficult and expensive to insulate at the support points.
The use of another of our products, Polyslip™ (a high molecular weight polyethylene), when fitted as pads on the circumference of the centraliser, provides a low friction interface with the caisson during the bundle 'pull-in'.
Features
We have overcome these inherent problems by moulding a segmental polyurethane bundle centraliser clamp which offers insulation and is in itself corrosion resistant. The ability to match the grade of poyurethane according to the applications generally ensures a 'coating friendly' centraliser possessing excellent structural strength and rigidity.
