MineWrap™ Insulation for Mining
Over the last several years Firwin Corp. has been developing a special line of insulation products aimed at meeting the stringent safety requirements for underground mining.MineWrap™ addresses the major areas of concern of underground mining:
- Danger of Hydraulic oil spills igniting on hot engine surfaces.
- Operator burns in confined mine tunnels.
- Oil seepage into insulation covers posing potential fire hazard.
- Hard wear conditions of underground mining.
ThermoWrap
ThermoWrap insulation blankets, also known as insulation covers or jackets, are found on valves of every shape and stripe - gate valves, flow valves, butterfly valves, etc. - as well as flanges, instrumentation panels, actuators, and of course process piping.
ThermoWrap blankets are generally used in lower temperature applications (typically well below 500°F) than their diesel and gas engine counterparts, where temperatures run 600°F and upwards.
This results in ThermoWrap blankets having a somewhat different 'look'-- Both the inner and outer covers for ThermoWrap blankets are typically made from silicone / PTFE reinforced fiberglass (as opposed to engine blankets, where the inner surface is typically stainless steel mesh).
- Polyester Velcro fastening and draw strings are common sights on ThermoWrap blankets; engine blankets are often too hot for drawstrings or Velcro (even the higher temperature options like Nomex).
T Wrap
T-Wrap™ is designed to provide the flexibility of tape with the added benefits of removable insulation blankets. The product features a silicone coated fiberglass outer cover, similar to Firwin’s standard removable insulation blankets. Underneath is either 1/4" or 1/2" fiberglass insulation. Hook and Loop strips line either side of the T-Wrap™ for easy fastening and removal. The product can be applied ‘straight on’ over the pipe, or wrapped around the pipe in a spiral fashion.Firwin’s T-Wrap™ is particularly suited for insulating:
- Electrically traced lines
- Glycol lines
- Instrumentation lines
- Small valves
- Small piping and tubing
The product is available in 20 ft. lengths and can easily be cut to shorter lengths using scissors. Available sizes range from 4” wide (0.25" O.D.) to 17" wide (4.00" O.D.).
Service Temperature: -67°F/-55°C to 200°F/95°C (** Temperature rating is to protect the hook and loop fastening system. If the hook and loop is kept away from the hot surface, a service temperature of 250°F/120°C can be acheived. Higher temperatures are avaible, please contact Firwin for more details).
