Assembly instruc­tions
Flanges

Correct assembly of the correctly matched compo­nents is essential for the safe and reliable functioning of the flange connection.

  The following assembly instruc­tions are based on DVS speci­fi­ca­tions for the assembly of flange connec­tions. Determine the materials used for the compo­nents of the “flange connection” system
  the required screw tight­ening torques. The screw tight­ening torques are required for the forces and the resulting necessary surface pressure. In addition to the flanges, the compo­nents in this system are the gasket as well as the bolts, nuts and washers. The flange partners can be made of different materials (PE100 and cast iron or steel, for example). The special properties of all compo­nents involved are therefore taken into account when calcu­lating the screw tight­ening torques under ideal condi­tions. The values listed then only apply to this constel­lation. Ideal condi­tions include stress-free instal­lation of the listed compo­nents at room temper­ature and loading of the flange connection only by the assumed load case (usually internal pressure). Additional loads that affect the connection and thus the surface pressure of the gasket must also be taken into account. In particular, temper­ature differ­ences during instal­lation, assembly and operation, which have a partic­u­larly strong effect on plastic pipes, as well as slopes without fixed points, must be taken into account by the planner as special instal­lation and operating condi­tions. We will be happy to assist you with any uncer­tainties and special instal­lation condi­tions. Our assembly instruc­tions and the screw tight­ening torques deter­mined for the respective flange type can be used to create a perma­nently tight flange connection for our flange solutions.
