MARINITE SLIDE PLATES Marinite is a higher density insulation formed from Calcium Silicate, which is light weight, has a low bulk density, a low thermal conductivity, a high temperature and chemical resistance. We generally provide Marinite as a rectangular slide plate assembly consisting of a Marinite insulator block sandwiched between a stainless steel top and bottom plate.

GENERAL DIMENSIONS & SPECIFICATIONS MARINITE SLIDE PLATE DIAGRAM REQUEST A QUOTE Piping Technology & Productsmarinite slide bearing plates (/products/slide-bearing-plates/marinite-slide-plates/)are rectangular slide-plate assemblies consisting of a marinite insulator block sandwiched between stainless steel top and bottom plates. These marinite slide bearing plates are held together by side plates along the length, and end plates along the width of the assembly.

Marinte Plates Construction The side and end plates have 1/4 diameter through holes and are stitch welded to the top and bottom plates.

The bottom plate is polished to a mirror nish for sliding along the surface of polytetrauoroethylene (PTFE) with minimal coecient of friction. The assembly is generally welded to shoes.

Coecient of Friction:

0.08 @ minimum pressure 0.06 @ maximum pressure Marinte Plates Application The marinite insulator assembly allows the use of polytetrauoroethylene (PTFE) as the sliding surface for lines with high operating temperatures and high dynamic loading. It protects the polytetrauoroethylene (PTFE) by acting as a barrier to heat transfer. It has so far been used for power plants high energy systems (SHP, SIP). It could potentially be used wherever there are movements at top, bottom or laterally at the point support.

So the benets of having a marinite insulator include:

Facilitates use of polytetrauoroethylene (PTFE) on high-temperature lines.

Marinite being a high load bearing insulation material is ideal for the dynamic conditions.

Marinite Plates: PT&Ps Capabilities Piping Technology & Products is a supplier ofmarinite slide bearing plates (/products/slide-bearing-plates/marinite-slide-plates/), which through proven testing allows for the use of polytetrauoroethylene (PTFE) as the sliding surface for lines, even under extremely high operating temperatures. Piping Technology

& Products has supplied these plates for a number of companies in the oil, gas and power industry.

Marinite can be used as the insulating material in hot piping supports. The most widely known grade for Marinite is grade P. Marinite-P is most often used as structural insulation because of its high dimensional stability. Marinite-P is incombustible, provides high insulation values, and high compressive strengths and is thus appropriate in high-load and high-temperature applications. The material minimizes decay, rust, and corrosion and it resists damage during installation and provides durable service. The material acts as a suitable insulator in reproong and heat processing equipment applications up to 1200°F (649°C).
