Transair® Stainless Steel Pipe Installation Instructions 3"(76mm) & 4"(101mm)

Sound engineering practice for the optimization of an air pipe system

■ When installing a Transair® system, work should be performed in accordance with good engineering practice.
■ Bends and bypasses represent sources of pressure drop.
■ Keep in-line pipe diameter reductions to a minimum.
■ The diameter of the pipe will influence pressure drop and the operation of point-of-use equipment.
■ Select the diameter according to the required flow rate and acceptable pressure drop at the point of use.
■ Never encase the network in a hard solid mass, in order to facilitate maintenance or servicing.
■ To insulate Transair® industrial water systems thermally, we recommend insulating the Transair® stainless steel pipes.
■ Position drops and feeds to take-off points as close as possible to the point of use.

1. Cutting the pipe:
place the pipe in the pipe cutter position the blade onto the pipe - rotate the pipe cutter around the pipe while gently tightening the wheel.

2. Carefully chamfer and deburr the end of the pipe with a file.

3. Creating the lugs with the Portable Crimping Tool Kit:
Open the retaining pin at the front of the machine by pressing the jaw release button.

Place the jaws in the housing.
Lock in position by closing the retaining pin

4. Manually open the jaws of the clamp and insert the aluminum pipe into the clamp as far as it will go

Release the jaws. Press the trigger and crimp the tube until a ‘snap’ sound is heard

Re-open the two jaws to remove the pipe and rotate the pipe slightly

Renew the operation until the required minimum number of lugs for each diameter is achieved

Min. number of lugs:
Ø 3" (76mm) (6 lugs)
Ø 4" (101mm) (7 lugs)
Do not overlap the lugs!

1. Slip the cartridge over the end of the first pipe fully up to the shoulder

2. Bring the second pipe to the cartridge and slide fully up to the shoulder

3. Position the clamp over the cartridge / pipe assembly

4. Hand tighten the pre-fitted screws with 6mm Allen key

5. Pull the pipes fully back towards the outside of the clamp

6. Tighten the clamp screws as follows:
■ mini tightening torque: 7.37 lbs ft
■ maxi tightening torque: make the 2 clamps touch together 17.5 lb-ft

For effective clamp sealing, screw tightening should be performed on alternate sides of the clamp as shown.
