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.
