Super Air Wipe Blows Off Pipe

A manufacturer of Electric Resistance Welded (ERW) pipes contact us recently. They were trying to make improvements to an existing pipe mill where pipes of diameters 3-1/2” up to 8-5/8” diameter are being processed. They had previously used our Super Air Wipe product on a smaller line that produced pipe in the 2-3/8” to 3-1/2” outside diameter range with great success. So, they wanted to know what we had that could blow off the outside diameter of their large product.

It so happens that EXAIR produces the Super Air Wipe product up to 11 inch inside diameter. With such a size, the Super Air Wipe has capability to blow off and cool pipes up to about 10 inch diameter. This capability was well within the need for our customer.

Previously, the customer had been using a series of open pipes that terminated into a ring around their product to blow off coolant used during the final phases of production. This solution was extremely loud and used a large volume of air which ran continuously while the mill was in operation. Also, the finish produced was not quite as consistent as the customer wanted. The inconsistent velocity between the home made “nozzles” caused lines to form on the pipe’s outer surface finish that were not appealing.

The Super Air Wipe was able to harness the compressed air into a more manageable flow with even velocity all the way round the outside of the pipe. The sound level dropped considerably, the flow rate dropped down to a much more reasonable level for the customer and the visual quality of their final product had no lines as before.

The pipes produced at this particular facility were used in the oil and gas industry. However, any application where pipes, hoses, tubes and any other round forms need to be blown off or cooled with air create good opportunity to take advantage of the features that an EXAIR Super Air Wipe bring to the application.
