Utility piping: Why over-engineering is inefficient
Grooved mechanical piping can offer improved constructability, speedy expansion, retrofit and turnaround, and also reduce safety risks. It is a quality pipe-joining method.
Refineries built in the 1950s to 1970s used all welded piping for both process and utility services. The specifications used during that time are often applied to retrofits, expansions and turnaround projects. But this reliance on the traditional specifications does have a downside. Scheduling, safety and constructability are three major factors in turnarounds. They are also the impacting factors that affect welding activities. However, alternatives, such as grooved mechanical piping, have been slow to gain acceptance due to the perception that the joining method wont work and a reluctance to use a gasketed joint.
