Bolt tightening torque procedure implies to stay away from the hole of the liquid from the joint. Jolt fixing arrangement or torque grouping is characterized in torque fixing technique. Most organization has their Flange jolt torque fixing system that utilized amid development and task of the plant. To accomplish the advantages of the pre-stacking, the clasping power in the screw must be higher than the joint partition stack.

• The torque esteem is subject to the contact between the strings of stud screw and nut head, this erosion can be influenced by the use of an ointment or any plating e.g. Cadmium or Zinc connected to the stud strings. The shooting standard will characterize whether the torque esteem is for a dry or greased up stud string. In the event that a screw is torque as opposed to the nut, the torque esteem ought to be expanded to adjust for the extra erosion fastener should just be torque on the off chance that they are fitted in leeway openings.

• Outwardly inspect the spine arrangement to guarantee that a satisfactory fit has been acquired. While adjusting ribs, ensure that there are no leftover worries in the joint. The utilization of warmth rectification for the arrangement of spines is entirely disallowed. Outwardly analyze nuts and screws before establishment to guarantee they are free from imperfections, for example, consumption, harm strings and so forth. Nut-screws with harmed strings ought not to be utilized. Check the length of the stud or dash to evade short darting and over the top strings.
• 
  
• Outwardly look at studs and nuts in the wake of cleaning to guarantee free from burrs. Studs and nuts will be cleaned utilizing a wire brush to evacuate any soil on the strings. Grease will be connected on strings and nuts to rib contact surfaces. Oil will not be utilized in the gasket and the gasket seating region. Bolt tightening sequence has to be abruptly followed.
• 
  
• The fastener and nut material evaluations ought to be accurately recognized before they are utilized. Fasteners and nuts must be reused on the off chance that it is realized that they have not been over-burden or surpassed their yield point. When collecting the nut on the screw, the nut recognizable proof stamping must dependably point outwards.
• 
  
• Try not to utilize fixing compound, oil or other glue or glue on gasket or spine faces. While gasket inclusion, it will not be constrained into the gasket situate between the mating rib faces. When the gasket is situated the mating spines are united cautiously without shaking the gasket off the seat, introduce all studs and run-up all nuts hand tight.
• 
  
• Outwardly inspect gaskets, before establishment, to guarantee they are free from deformities. Shading coding will be kept up according to the rate and sort of gasket given by the produce. Clean gasket seating face utilizing a wire brush. Ensure the material is as indicated, search for any conceivable imperfections or harm in the gasket, for example, overlap or wrinkles.
