2013 12 Kernberger SBN Bolting of HP equipment Part 1-4 (complete)

When we in 1986 started with the manufacturing of High Pressure (HP) Urea equipment we had to build the equipment in accordance with the Licensor’s or enduser’s specifications. One of the items that were strictly specified was the design of the man way covers.

Over the years we gained not only a lot of experience with the gaskets for man way covers but also with bolting down these gaskets. In these technical papers we share our experience of some forty years with you.

The most common used gasket design in HP Urea Equipment is the flat type gaskets. For a long and reliable service of these gaskets, it is essential that not only the gasket and bolting are engineered correctly but also that the maintenance of this bolting is performed correctly. Throughout the years problems with this bolting is reported, leading to a delay in start up and consequential to that, loss of production. From the number of failures reported one can conclude that bolting is a critical issue.
