A simple solution is to install a heavy duty conical spring between nut and structure. the conical spring is to be totally flattened. the conical spring will completely prevent loosening of nut under vibration, impact and thermal expansion. unlike spring washers conical springs exert uniform load and the load capacity is 5-10 times of spring washers.
4 moc: spring steel for temp up to 150 Degree C, chrome vanadium steel for temp. up to 250 Degree C. each spring is coated for marine grade corrosion resistance. these conical springs can be reused any number of times, thus they are a one-time investment


Notes :
  • We recommend you use a minimum of 8.8 grade (high tensile) fasteners to use conical springs.
  • Apply a small amount of grease to nut/bolt before tightening.
  • In many applications, chrome vanadium conical springs can eliminate hot bolting in flanges, heat exchangers & valve bonnets, etc.

If you install a heavy duty conical spring between the nut and bolt below the structure it ensures the nut is under constant tension thus preventing it from loosening. in many countries, these springs are therefore called tension spring. the conical spring is to be fully flattened. the conical spring Will adjust itself against thermal expansion but ensures that bolt/nut assembly does not get loosened. no need for frequent tightening. the conical spring is made from high-grade spring steel, heat treated and coated with special corrosion resistant powder coating (96 hours salt spray test). you can retighten it any number of times (in case the equipment is sent for maintenance or overhaul.) the conical spring thus has a life of several years.

These are small handy, portable tools which are used to create a gap between flanges to remove gaskets. etc. using tommie's / rod etc. to create a gap in flanges can cause severe damage to flange faces: also there is sometimes a risk of sparks.

All you need to do is to remove all flange, bolts/studs, and locate support studs of spreaders in these two holes. apply torque to both levers at both ends. the tip acts as a wedge and lifts the flange face. you can keep the flanges open till such time you need to take out old gasket & put the new one. then retract the spindle. after this, the original bolts of the flange can be replaced. these tools are suitable for small/medium size flanges having maximum bolt size of 1" higher sizes require hydraulic tools.

All elements are made from alloy steel & hardened. This gives long LIFE to the tool. Since these are mechanical devices, no external power source is required.

Conventionally industry has been using spring washers to tighten nut/bolts. these spring washers do not exert a uniform load because of their geometry ref. fig. 5. conical springs exert a uniform load along the periphery. moreover, the load exerted by conical springs is several times higher than springs washers. it is for these reasons springs washers are slowly getting phased out in advanced countries.

Notes :
  • We recommend you use a minimum of 8.8 grade (high tensile) fasteners to use conical springs.
  • Apply a small amount of grease to nut/bolt before tightening.
  • Max temperature of conical spring is 150°c for alloy spring steel, 250°c for chrome vanadium spring steel
  • In many applications, chrome vanadium conical springs can eliminate hot bolting in flanges, heat exchangers & valve bonnets, etc.
