Thermal insulation material for subsea equipment

摘要: The invention is an insulation material comprising a novolac cured polysulfide polymer resin. used as thermal insulator for subsea gas and oil production equipment, such pipes wellhead equipment. In order to decrease the maximum exothermic temperature generated by resin during curing, hollow glass beads are added amine content of hardener in standard was adjusted further temperature. A fumed silica thixotropic also increase viscosity mixture. These modifications allow be cast thick sections without cracking, leaking, or excessive expansion curing.
