USIFLEX® Pipe is a simple, rugged, bottle-tight flexible restrained joint without the use of bolts. USIFLEX Boltless Flexible Joint Pipe is ideally suited for underwater installations where the high cost of equipment and manpower emphasizes the importance of ease and speed of assembly. USIFLEX Pipe may also be used for other types of installations where an appreciable amount of joint deflection and a positive lock against joint separation is required.

USIFLEX Pipe has a design working pressure of 350 psi for sizes 4"–12" and 250 psi for sizes 14"–48". The maximum joint deflection for all USIFLEX Pipe is 15°. For design and installation purposes a 12° limitation is recommended to allow for additional deflection after installation. For higher working pressures consult your U.S. Pipe Representative.

The gasket and the retainer ring lock are the only loose accessories. No bolts, nuts or wrenches are required to make up the joint. Fewer accessories to handle and account for means a substantial savings in time and labor.

The design of the gasket and gasket seat is such that, rather than being dependent on an exterior force from a gland, the gasket is self-sealing.

Only a moderate longitudinal thrust is required to insert the ball into the socket.

Clearances between the machined retainer ring and the bell permit easy entry and rotation of the retainer ring in the bell.

Because of the unique design, when the joint is subjected to end pull, the rugged retainer ring withstands the radial forces and prevents transmittal of these forces to the bell casting.

The inside contour at the end of the ball is shaped so that when the joint is deflected, the ball does not project into the waterway to obstruct the flow.

advantages

42" USIflex pipe fully deflected to 15º at 500 psi test pressure (2 times rated pressure).

The flexibility of the joint permits bottle-tight operation at deflections up to 15º.

USIFLEX Pipe are shipped with a shop-applied protective coating on the machined surface of the ball. Before assembly, remove the coating with acetone or methyl ethyl ketone.

Insert the USIFLEX Gasket into its seat in the socket.

Lubricate the ball and exposed surface of the inserted gasket with TYTON JOINT® Lubricant. In warm, dry weather conditions, the lubricant can dry out, especially when applied to warm or hot pipe, it will be necessary to add a small amount of water to hydrate the lubricant. Only TYTON JOINT Lubricant should be used. This will permit easy assembly and deflection of the joint. The lubricant furnished is a non-toxic material. If assembly is to be made underwater, special lubricant can be furnished. Lubricant other than that furnished with the pipe should not be used.

CAUtIoN: The use of spray-on lubricant is not recommended. experience has determined that spray-on lubricant may not have sufficient lubricity to allow joint assembly without gasket displacement.

With the entering pipe suspended by a crane or other means, place the lubricated ball in the receiving bell and force the ball into the socket, thereby compressing the gasket to effect a bottle-tight seal. While keeping the ball forced into the bell bring up the retainer ring, line up the lugs with the recesses in the bell, move the retainer ring inward and turn it until the retainer ring lugs interlock with the internal flange segments in the bell. If the retainer ring cannot be rotated, make sure the ball is firmly pushed into the socket; ample clearance is provided by a slight amount of joint slack or pull out to enable easy assembly.

Insert one retainer ring lock into a space between two segments to hold the retainer ring in the locked position, then caulk the retainer ring lock to keep it in place. Only a few hammer blows on a wide caulking iron are sufficient. only one retainer lock is required per joint to prevent the ring from rotating.

Figure 1.Insert the gasket into its seat in the socket. Forming gasket loop helps initial stage of seating. Release the gasket and press it into the gasket seat where it is securely held.

Figure 2.Apply lubricant to the ball and exposed surface of seated gasket in socket. Lubricant other than that furnished with the pipe should not be used. After lubrication, ball is ready to be pushed into socket.

Figure 3.Ball has been socketed. Retainer ring lugs have been lined up with recesses in bell and retainer ring is ready to be moved into the bell and rotated.

Figure 4.After insertion and rotation of retainer ring in bell, the lugs on retainer ring are in back of and in register with internal flange segments in bell. Retainer ring lock is shown partially inserted into recess between the bell and retainer ring.

Figure 5.Retainer ring lock completely inserted into recess is being caulked in place by hammer blows on a wide caulking iron. Pull back on pipe to engage the ball into the retainer ring.

24" force main being installed across the Passaic River at Garfield, New Jersey.

Submarine installations, the type of service for which USIFLEX Pipe is usually used, are so varied that a specific installation procedure cannot be recommended. Some methods that have been used successfully by installers of flexible joint submarine lines are:

• Assemble two or more sections above water, lower with the aid of a strongback or multiple slings from a derrick barge and have a diver make up connecting joints under water.

• Lay the pipe with a chute or cradle attached to a derrick barge or similar type of floating equipment.

ramp launching and flotation method Assemble the joints on shore, attach empty drums to aid buoyancy, pull into the water by attached cable and lower to the bottom by progressively releasing the drums or allowing them to fill with water. Barrels should be retrieved after installation is complete.

Each joint of USIFLEX Boltless Flexible Joint Pipe provides variable deflection up to 15° and the joint may be deflected to this position without harm to the pipe or joint components. A 12° installation limitation is recommended to provide additional deflection capability to accommodate earth settlement or movement. Care should be taken, however, to ensure that no joint is ever forced beyond the 15º maximum design deflection.

When USIFLEX pipe is installed in areas of water traffic, shallow depths or waterways prone to flood caring debris, the pipe should be laid in a trench or backfill placed over the pipe to reduce the chance of damage to the pipe. All the pipe joints should be supported underneath each bell. A thorough bottom survey in the design stage of a project will reveal if backfill or support is required under the pipe to stay within the deflection limits of the joint.

installation (cont.)

suspension from temporary supports This method of installation in Lynbrook, NY involved gradually submerging the 16" pipeline from a pile and timber runway. Lowering of the pipe proceeded by successively easing off on the supporting rope slings (of which there was one at each joint) until the pipe lay in the excavation which had been prepared for it.

table 1. nominal lengths in Feet The weight of submerged pipe may be calculated with the aid of the information in Tables 1-3. Preliminary calculations may be made using the nominal weights and lengths shown in the tables. Take into consideration that the actual weights will vary within the scope of manufacturing tolerances. If the pipe are on hand, more accurate weight determination may be made using the actual measurements and marked pipe weights.

Method of calculation:1. Measure the length of the barrel from the bell skirt to the ball or select the

nominal barrel length from Table 1.

2. Multiply the length of the barrel in feet by the displacement volume per foot of barrel from Table 2 or 3 to obtain the barrel displacement volume.

3. Add the barrel displacement to the assembled joint displacement from the appropriate table to obtain the total pipe displacement volume.

4. Multiply the total pipe displacement in cubic feet by the density of the medium in which the pipe is to be installed (approximately 62.4#/cu. ft. for fresh water, 64.0#/cu. ft. for salt water, etc.) to obtain the weight of the displaced medium.

5. Subtract the weight of the displaced medium from the marked pipe weight, or from the nominal pipe weight in the tables, plus the accessory weight to obtain the weight of the submerged pipe. (A negative value indicates that the pipe will float.)

4"–48" Pipe calculation of Weight When submerged

lengths in this table are based on the maximum nominal laying lengths of 18.5' or 21' for 4" – 24", 19' for sizes 30" – 36", 22' for 42 – 48".

* Nominal weights are based on nominal lengths and thicknesses and are subject to manufacturing tolerances. Weight includes pipe, retainer ring, and cement lining.

The maximum nominal laying lengths are 18.5' for 4" – 12", 21' or 18.3' for 14" – 24", 19.5' for 30" – 36", 22' for 42" and 22.25' for 48". Actual laying lengths may vary from published to slightly over nominal. A maximum of 10% of the total number of pipe each size of an order may be fur-nished with laying lengths to 2 ft. shorter.

If more exact lengths are required, pipe may be furnished cut to length at an additional charge. Cut lengths shall not exceed the nominal laying length and will be subject to a tolerance of plus or minus 1/2".

The maximum working pressure rating is U.S. Pipe’s suggested rating based on a conservative factor of safety to allow for laying and service conditions encountered in marine installations. The design engineer must decide whether barrel thicknesses shown are adequate to meet installation and service conditions for a particular project.

Maximum allowable deflection of joint is 15°.
