1004SS Back Blow Air Nozzle Clean Inside Small Diameters

Model: 1004SS

A metal fabricator made stainless steel tubes with a ½” (13mm) inner diameter.  Their process started by cutting the tubes into 8” (203mm) lengths.  The tubes would go through a wash system, then to a honing machine.   Once the inner diameter was honed to the specific diameter and concentricity, the tubes would be washed again for packaging.  The honing machine used oil to accurately grind the inner diameter.  Since oil and water does not mix, they had to dry the I.D. before honing.  They contacted EXAIR to see if we could find a solution.

Back Blow Air Nozzle Family

For cleaning the I.D. of parts, EXAIR manufactures three different sizes of Back Blow Air Nozzles that are designed to clean inside tubing, pipes, hoses, and channels.  They can range from internal diameters from ¼” (6.3mm) up to 16” (406mm).  The 360o rear airflow pattern can “wipe” the entire internal surface without contacting the surface to remove water, coolant, chips, and debris.  In reviewing the inner diameter above, I was able to recommend a model 1004SS Back Blow Air Nozzle.  This 316SS robust designed nozzle can fit inside and clean tubes with internal dimensions ranging from ¼” (6.3mm) to 1” (25mm); perfect for the ½” (13mm) diameter tube.

Model: 1604SS-12-CS

The customer indicated to me that there was a rush to start this project.  EXAIR stocks thousands of cataloged items for same day shipping.  He asked if EXAIR had any other components to help them to expedite their drying process.  Well, of course we do!  Since the tube was 8” (203mm) long, EXAIR has extension tubes that are used with our VariBlast Compact Back Blow Safety Air Gun.  We have them ranging from 6” (152mm) to 72” (1829mm) in incremental lengths.  For this customer, I recommended the 12” (305mm) extension to reach through the tube.  And, since it was a manual operation, I also recommended the model 9040 Foot Valve.

Model 9040 Foot Valve

Their operator could place the tube over the model 1004SS Back Blow Nozzle and with the Foot Valve, turn on the compressed air to dry the tubes.  With the powerful air stream, the entire internal surface was dry for the honing process to follow.

If you need to clean the inside of tubes, hoses, pipes, etc., EXAIR has the perfect nozzles for you, the Back Blow Air Nozzles.  EXAIR can attach these nozzles to our VariBlast Compact, Soft Grip and Heavy Duty Safety Air Guns for easy-to-use operations.  For this customer above, they were able to use components to get the operation running the next day.  If you need more information, you can share your application with an Application Engineer at EXAIR.  We will be happy to help.

Back Blow Air Nozzles Clean Out Pipe, Tubes and Holes

Round SS Tubes

A metal fabricator used a cutting machine to cut different sizes and shapes of stainless steel tubing.  The process was automated and the machine would cut two tubes at a time.  After the cutting operation, the machine would deposit the tubes into a nearby bin.  The operator would then stack the tubes in a wooden container as shown above.  Before the tubes could be transported to another department, the operator would have to clean the inside of each tube.  The current method was to attach a rag to the end of a rod and pushed it inside the tube to remove any coolant and chips that remained from the cutting operation.  Of course, the ability to clean thoroughly with a rag is reduced greatly after a short time of use.  The cleaning process was very time consuming, and when the rag was not changed in a timely manner it did not clean effectively.  The inside of the tubes would get marred from the excess chips that remained on the rag.  This would visually affect the surface finish of the stainless steel.  They emailed me the application detail as they were looking for a non-contact way to clean the inside of the tubes.

The first question from the customer was if we could customize our air nozzles to clean the different diameters and shapes that they were cutting.  EXAIR has made special air nozzles to accommodate unique applications, but I wanted to first make sure that EXAIR did not have a manufactured nozzle in stock to fit this application.  I requested the dimensional information, and the customer sent me the sizes and shapes of the tubes that were ran through their cutting machine.  (Reference Table 1 below).

EXAIR manufactures three different sizes of Back Blow Air Nozzles that are designed to clean inside tubing, pipes, hoses, and channels.  They can range from internal diameters from ¼” (6.3mm) to 16” (406mm).  The 360o rear airflow pattern can “wipe” the entire internal surface clean and can remove coolant, chips, and debris.  In reviewing the dimensions from Table 1 above, I was able to recommend just one Back Blow Air Nozzle for all the tubes; even the square and rectangular ones.  It was model 1006SS Back Blow Air Nozzle.  This 316SS robust designed nozzle can fit inside and clean tubes with internal dimensions ranging from 22mm to 102mm, and it was perfect for all of these tubes.

Soft Grip Safety Air Gun w/ Back Blow Air Nozzle

The customer indicated to me that the tubes were all cut to identical lengths at 550 mm (21.7”).  Being that this was a manual operation, I suggested the Back Blow Air Nozzle with our Soft Grip Safety Air Gun.  This ergonomically designed Safety Air Gun is designed for hours of use without fatigue.  In combination with the nozzle, we are able to add extensions and chip shields.  With extensions, EXAIR has a range of lengths from 6” (152mm) to 72” (1,829mm).  With the designated length above, I recommended the model 1206SS-24-CS which has the Soft Grip Safety Air Gun, the model 1006SS Back Blow Air Nozzle, a 24” (610mm) extension, and a chip shield.

The configuration allowed for the operator to reach through the tube to clean with only a one-time pass.  The CS designation is for a chip shield which will protect the operator from any excess debris and coolant.  With the model 1206SS-24-CS, the operator could now pick up a tube, use the Soft-Grip Back Blow Safety Air Gun to remove the debris and coolant from within the round tubes, square tubes and rectangle tubes.  Also, they did not have to worry about changing the rags when it got dirty.  What an amazing purchase for this company, as they increased the speed of the cleaning operation by 70% without affecting the inside finish of the stainless-steel tubes.

If you need to clean the inside of tubes, hoses, pipes, etc., EXAIR has the perfect nozzle for you, the Back Blow Air Nozzles.  EXAIR can attach these nozzles on our VariBlast Compact, Soft Grip and Heavy Duty Safety Air Guns for easy-to-use manual operations.  For this customer above, they were glad that they contacted EXAIR about their application.  If you require more details, you can share your application with an Application Engineer at EXAIR.  We will be happy to help.

Back Blow Nozzles Clean Inside Metal Tubes

A manufacturing plant EXAIR worked with made cast aluminum tubes for the automotive industry.  After the parts were cast, a machining operation would clean the ends.  This left coolant and metal shavings inside the tube.  Before going to assembly, they had to clean the part.  They created a two-tube fixture (reference picture above) to fit the 25mm tubes in place.

Two home-made nozzles were used to fit inside the tubes to blow compressed air.  The nozzles were attached to the ends of two 17mm pipes which supplied the compressed air.  A cylinder was used to push the nozzles from the top of the aluminum tube to the bottom then back up again.  The liquid emulsion and debris would be pushed downward into a collection drum.  When they started operating their system, the inside of the tubes still had contamination inside.  They wanted to improve their process, so they looked for an expert in nozzle designs, EXAIR.

Back Blow Air Nozzle Family

EXAIR designed and manufactures a nozzle for just this type of operation, the Back Blow Air Nozzles.  We offer three different sizes to fit inside a wide variety of diameters from ¼” (6.3mm) to 16” (406mm).  They are designed to clean tubing, pipes, hoses, and channels.  The 360o rear airflow pattern can “wipe” the entire internal surface from coolant, chips, and debris.  For the application above, I recommended the model 1006SS Back Blow Air Nozzle.  This 316SS robust design would fit inside the tubes above.  The range for this Back Blow Air Nozzle is from 7/8” (22mm) to 4” (102mm) diameters.  The customer did have to modify the function of the equipment by placing the cylinder and the rods under the aluminum tubes.  The reverse airflow would still push the contamination into the collection drum that was placed underneath the tubes.

After installing the model 1006SS onto the rods, the cleaning operation became more efficient.  Not only was the entire internal diameter getting clean, they were able to turn off the compressed air until they reached the top of the tube.  With the model 1006SS, they only needed one pass to clean.  This cut the air consumption in half, saving them much money by using less compressed air.  In addition, they were able to speed up their operation by 20%.  Cleaner tubes, less time, cost savings; they were happy that they contacted EXAIR for our expertise.

Reverse Air Flow

If you need to clean the inside of tubes, hoses, pipes, etc., EXAIR has the perfect nozzle for you, the Back Blow Air Nozzles.  EXAIR can also offer these nozzles on our VariBlast, Soft Grip and Heavy Duty Air Guns for manual operations.  They come with Chip Shields and extensions that can reach as far as 72” (1829mm).  Or like the customer above, automate the system to get a great non-contact cleaning.
