Positive Mustang Endorsement Jim Lawrence (Principle Engineer Control Systems & Instrumentation) at Mustang Engineering in America has given a clear endorsement for Tungum Tubing for a new project in Canada. His recommendation is that Tungum Tubing is included in the Philosophy document, stating: “Consideration should be given to the use of Tungum tubing in locations where tubing replacement is difficult and long term use without maintenance is required.”
