Grooved and Shoulder Joints use u-shaped coupling that goes around the plain end of a pipe that either has a groove cut into it or a shoulder threaded onto it. The u-shaped coupling fits into the groove to join/restrain the pipe.
You can find more information on our web, so please take a look.
Inside the u-shaped coupling is a gasket that compresses between the coupling and the pipe to form the watertight seal. This type of joint is used in above-ground applications. Grooved/shoulder joints should never be used in underground applications.
Grooved joints are available in flex or rigid configurations depending on the need for deflection.
Ball and Socket Pipe has the greatest degree of deflection of any joint, for up to as much as 4.5 feet of offset for an 18-foot length of pipe. It ranges from twelve to fifteen degrees per joint. This joint describes itself.
Components of the River Crossing joint are machined to precise dimensions providing optimal deflection capabilities. Pipe class options are also available, providing installation options to either &#;float&#; or &#;sink&#; the pipe into place. Like the wing of an airplane, the structure and strength of this specialized joint serve to split any water or current it passes through harmlessly while it settles to the bottom of the waterway on its own.
This joint deflection may be horizontal or vertical. This deflection capability allows the pipe to be assembled on the bank or the back of a barge. The joints deflect as needed to adapt to the bottom of any waterway.
AMERICAN provides a complete line of standard as well as many special flanged fittings for various types of service, including water, sewage and air.
Most of the flanged fittings furnished by AMERICAN are manufactured in accordance with the requirements of this standard. Such fittings in this section are designated with the heading &#;ANSI/AWWA C110/A21.10.&#; The AWWA C110 fitting flanges have facing and drilling that match AWWA C115 threaded-on flanges (see Flanged Joint Pipe) and which also match ANSI B16.1 class 125 flanges.

AMERICAN provides some fittings that are not included in AWWA C110, including long-radius 90° bends, reducing bends, wyes and various other fittings commonly used in plant piping. These have AWWA C110 flanges and are denoted by the heading &#;AMERICAN Standard.&#; Pressure ratings shown are AMERICAN Standard and are based on AWWA C110 design principles.
AWWA C110 flanges are adequate for a water working pressure of 250 psi with the body of the fitting being suitable for 150 or 250 psi as indicated. In some cases, these fittings have been supplied for greater water working pressure applications, particularly when used with AMERICAN Toruseal gaskets.
54", 60" and 64" fittings are manufactured in accordance with AWWA C153. Flanges match AWWA C115 and ANSI B16.1 (class 125) flanges and are adequate for a water working pressure of 250 psi. (64" flanges match 66" flanges. See the table in Standard Dimensions). The bodies of these fittings are suitable for 150 psi or 250 psi as indicated. In some cases, these fittings have been supplied for greater water working pressure applications, particularly when used with AMERICAN Toruseal gaskets.
Except for a transition fabricated pipe from an ANSI B16.1 class 250 flange to a standard AWWA C110 flange, AMERICAN no longer furnishes fittings with flanges faced and drilled per ANSI B16.1 class 250.
As noted in AWWA C111, flange joints in the 24" and smaller sizes may be rated for up to 350 psi with the use of special gaskets such as AMERICAN&#;s Toruseal gasket.
Furthermore, AMERICAN is able to rate flange pipe and fittings higher than 350 psi on special applications.
Information on fittings class 250 F&D previously furnished by AMERICAN can be found in the Guide to Historical Data.
