Grooved Series Installation
PREPARATORY STEP FOR COUPLING INSTALLATION FOR AIRCOM GROOVED SERIES INSTALLATION
1 – Check Pipe Ends
The outside surface of the pipe, between the groove and the pipe end, must be smooth and free from indentations, projections (including weld seams), and roll marks to ensure a leak-tight seal.
2 – Check Gasket & Lubricate
Check the gasket to make sure it is suitable for the intended service. Apply a thin coat of AIRCOM lubricant to the gasket sealing lips and exterior.
3 – Position Gasket
Position the gasket over the pipe end. Make sure the gasket does not overhang
the pipe end.
4 – Join Pipe Ends
Align and bring the two pipe ends together. Slide the gasket into position and center it between the groove in each pipe end. Make sure no portion of the gasket extends into the
groove in either pipe end.
5 – Assemble Housing
Insert one bolt into the housings, and thread the nut loosely onto the bolt to allow for the “swing-over” feature, as shown above. The nut should be backed off no further than flush with the end of the bolt.
6 – Install Housing
Using the “swing-over” feature, install the housings over the gasket. Make sure the housings’ keys engage the grooves completely on both pipe ends.
6 – Install Remaining Nuts & Bolts
Install the remaining bolt, and thread the nut finger-tight onto the bolt. Make sure the oval neck of each bolt seats properly in the bolt hole.
6 – Tighten Bolts
Tighten all nuts evenly by alternating sides until metal to-metal contact occurs at the angle bolt pads. Make sure the housings’ keys engage the grooves completely on both pipe ends and that the offsets are equal at the bolt pads. Equal, positive offsets are necessary to ensure a rigid joint (refer to the example above). It is important to tighten all nuts evenly to prevent gasket pinching.
Visually inspect the bolt pads at each joint to ensure metal-to-metal contact is achieved.
Flange Adaptor Installation 168 & 220mm Aircom Grooved Series Installation
Flange Adapters require a smooth, hard surface at the mating flange face for proper sealing. Some applications, for which the Flange Adapter is otherwise well suited, do not provide an adequate mating surface. In such cases, a metal Flange Washer is recommended for insertion between the Flange Adapter and the mating flange to provide the necessary sealing surface.
- When mating a flange to a serrated flange – a flange gasket shall be used against the serrated flange. The Flange Washer should then be inserted between the Flange Adapter and the flange gasket.
- When mating a flange adapter to a wafer type valve – – the Flange Washer shall be placed between the valve and the Flange Adapter.
- When Mating a flange adapter to rubber faced flange valve – the Flange Washer must be placed between the Flange Adapter and the rubber-faced flange
- Mating to components when component has an insert – follow the same arrangement as if the Flange Adapter was being mated to a serrated flange.
- Adapters – the Flange Washer must be placed between the two Flange Adapters with the hinge points oriented 90° to each other. If one flange is not a AIRCOM Flange Adapter (i.e. Flanged valve), a flange gasket must be placed against the non-AIRCOM Flange. The Flange Washer must then be inserted between the flange gasket and the Flange gasket.
1 – Check Pipe Ends
The outside surface of the pipe, between the groove and the pipe end, must be smooth and free from indentations, projections (including weld seams), and roll marks to ensure a leak-tight seal.
2 – Check Gasket & Lubricate
Check the gasket to make sure it is suitable for the intended service. Apply a thin coat of AIRCOM lubricant to the gasket sealing lips and exterior.
3 – Position Gasket
Position the gasket over the pipe end. Make sure the gasket does not overhang
the pipe end.
4 – Install Flange Adapter
Open the hinged flange adapter fully, and install the flange over the gasket. Make sure the flange key section engages the pipe groove properly.
5 – Insert Mating Bolts
Insert a standard, full-shank diameter assembly bolt through each of the two mating hole in the flange adapter. This will maintain the position of the flange in the pipe groove.
5a – Make Sure Gasket is Seated
Make sure the gasket is seated properly in the flange adapter
Closure lugs are provided for ease of installation. If necessary, use an adjustable wrench to bring the flange holes intovalignment. This will ease insertion of the
6 – Join Flange Adapter and Mating Flange
Join the flange adapter with the mating flange by aligning the bolt holes.
6a – Thread standard Flange nuts Finger-tight onto the two mating bolts.
7 – Install Remaining Bolt and Nuts
Insert a standard, full-shank diameter assembly bolt through each remaining hole in the flange adapter/mating flange. Thread standard flange nuts finger-tight onto all bolts.
8 – Tighten Nuts and Bolts
Tighten the nuts evenly, as with a regular flange assembly. Continue tightening until the flange faces come into firm, metal-to-metal contact or the standard, flange-bolt torque requirement is achieved.
Quick Brach 168-220mm Grooved Series Installation
- Proper preparation of the hole is essential for sealing and performance. Make sure the correct hole saw size is being used. Refer to the Pipe Preparation Requirements” table.
- Holes MUST be drilled on the centerline of the pipe.
- Ensure that a 5/8 inch – 16-mm area around the hole is clean, smooth, and free from indentations and/or projections that could effect gasket sealing (refer to the sketch below). Remove any burrs and sharp or rough edges from the hole. Burrs and sharp edges might effect assembly, proper seating of the locating collar, flow from the outlet, or gasket sealing.
- The pipe around the entire circumference, within the “A” dimension shown in the sketch below, must be free from any dirt, scale, or projections that might prevent the housing from seating fully on the pipe. Refer to the Pipe Preparation Requirements” table.
DO NOT USE STYLE BOLTED BRANCH OULTELS ON PVC PLASTIC PIPE.
Assemble Housing
Insert a bolt into the two housings. Thread a nut loosely onto the end of the bolt.
Check Gasket & Lubricate
Inspect the sealing surface of the gasket to make sure no debris is present.
The Correct Gasket is Shipped Depending on Branch Drop
Install Housing
Rotate the lower housing so that it is positioned approximately 90° to the upper (outlet) housing, as shown above. Place the upper (outlet) housing onto the face of the pipe in line with the outlet hole cut into the pipe. Rotate the lower housing around the pipe.
Install Housing Continued
Make sure the locating collar engages the outlet hole properly. Check this engagement by rocking the upper (outlet) housing in the hole.
Install Remaining Bolts
Insert the remaining bolt. Thread a nut onto the bolt finger-tight. Make sure the oval neck of each bolt seats properly in the bolt hole.
Tighten Nuts
Make sure the locating collar is still positioned properly in the outlet hole. Tighten the nuts evenly by alternating sides until the upper (outlet) housing contacts the pipe completely.
