L70 Sealing of Flanged Joints

Integrate the leak-tightness factor as of the design stage by using the appropriate procedures, knowing the properties of the seals and by applying the appropriate design analysis method.

OBJECTIVES

Upon completion of the training, the participants will be able to carry out the following:
• describe the behaviour of a flanged joint fitted with a seal;
• specify the leak-tightness solutions (flat seals for flanged joints) based on the conditions of use;
• define standard practice for factoring leak-tightness into the design of flanged joints

PRE-REQUISITES

None.

PEDAGOGICAL MEANS

Theory and laboratory demonstrations.

WHO SHOULD ATTEND

Engineers and technicians from Design departments, manufacturers and suppliers of seals, Quality departments, designers of pressurized equipment, project owners.

RECOMMENDED FURTHER TRAINING

L67 – Designing joints with sealing flanges in accordance with EN 1591
