Creep is a phenomenon that occurs in the materials used for the manufacture of flat gaskets and which is not given enough importance.
To understand what the creep of a flat gasket means, let's suppose that you have installed a gasket like the one in the image above, with the recommended tightening torque, which in this case is 100 N-m on each bolt.
Two days later and before starting up the installation, following the plant safety protocol, you proceed to verify the tightness of the gaskets. To your surprise, the bolts of the flange where you installed the...
On October 4, a technical conference was held at the Lliçá de Vall facilities, focused on products for difficult applications, especially developed for the chemical and petrochemical industry sectors, as well as the pharmaceutical and food industry, renewable energies and cogeneration. The various conferences were led by Andre Hunter of Inpro/Seal and Friedrich Gueldenberg of Revoseal. In these areas, quality, performance and durability must be beyond any doubt, as they are decisive for productivity and uptime....
The factors that influence the service life of an O-ring can be classified as part-specific (housing design and material selection) and external, such as installation, handling and working conditions, among others.
Even if the housing design is correct and the right material is chosen, the service life of the O-ring may be shorter than expected and deteriorate. As a result, if fragments of the O-ring appear in process and are also easily recognizable by a machine vision system, then the chances of the O-ring being damaged are very low....
For the distribution of process fluids, whether in intermediate or finished products, seals such as camlock type seals for quick couplings are essential.
The lines for transferring these fluids to transport tanks are connected to the tanks by means of “quick” couplings that allow the hoses to be connected and disconnected manually and efficiently. The “quick release” couplings have a sealing gasket that prevents liquid spillage during loading and unloading of the tanks.
Sealing gasket solutions:
