As a final review, consult the table below for a comprehensive summary of the materials of construction for the EXAIR Stainless Steel and Aluminum Super Air Wipes and the Standard Air Wipe.
If you have questions about the Air Wipes, or would like to talk about any of the EXAIR Intelligent Compressed Air® Products, feel free to contact EXAIR and myself or any of our Application Engineers can help you determine the best solution.
A large manufacturing company called looking for a better solution to control the thickness of a curing agent being applied to the outside of tubing used in the automotive industry. The tubing is formed in an extruder and travels through a liquid cooling chamber and then air dried. After the tubing is dried, it is sent to a spray chamber where the curing agent is applied to the exterior. On the exit side of the spray chamber, the customer had installed several flexible air lines placed around the perimeter of the tubing to blow air across the surface to help control the coating thickness. This worked somewhat but they were seeing an increase in the amount of rejected material as the air pattern was sporadic and uneven, which caused streaking and dry spots in certain areas of the tubing. They reviewed our web site and familiarized themselves with our Air Wipes but were unsure of the best design and size to fit their need so they reached out for assistance.
After further discussing the process, their tube O.D. sizes range from 3/8″ – 1/2″, making our 1″ Air Wipe the ideal solution. As far as the design, the Standard or Super Air Wipe, I recommended they use our Model # 2451 Super Air Wipe kit due to the aluminum construction and stainless steel wired braided hoses being able to withstand the potential temperature in the area of 200°F. The kit includes a filter separator to remove any water or contaminants in the supply and a pressure regulator which would allow them to control the flow and force of the exiting air, to help “dial” it in to fit the demand of the application.
EXAIR Air Wipes features a split design, which can easily be clamped around the material, to provide a 360° uniform airflow, perfect for treating the surface of round shapes, like extruded tubing. If you have an application where you are needing to dry, cool or clean the outside of a pipe, hose or cable, contact an application engineer for help making the best product selection.
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.
