The ESNA Nut Series of MacLean-Fogg Component Solution in the United States has once again been certified by the US Aerospace and Defense Defence Program (Nadcap), this time for the chemical processing of its Type 1 and Type 11 passivation, and also following 2014. Another certification after Nadcap for non-destructive testing was obtained in April.
ESNA is currently passivated with nitric acid and sodium dichromate. This ability ensures that the products ordered by the customer have passed the highest standard of passivation. This highlights the ESNA Series' ongoing efforts to demonstrate responsibility for quality sustainability by meeting customer requirements and industry specifications.
ESSA Quality Manager Teresa Melton said: "At ESNA, we continue to set higher standards with the goal of becoming the benchmark for other laboratories in the industry."
Weld-Neck flanges or welding-neck flanges can be differentiated from all other types of flange by their long tapered hub. The Welding neck flanges is normally referred to as the high hub flange. It is designed to transfer stresses to the pipe, thereby reducing high stress concentrations at the base of the flange. A weld neck flange (also known as a high-hub flange and tapered hub flange) is a type of flange. There are two designs. The regular type is used with pipes. The long type is unsuitable for pipes and is used in process plant. A weld neck flange consists of a circular fitting with a protruding rim around the circumference. Generally machined from a forging, these flanges are typically butt welded to a pipe. The rim has a series of drilled holes that permit the flange to be affixed to another flange with bolts.
