Standard Joint

Primary application: This bell and spigot joint is normally used for embedded cylinder pipe in 54-inch through 144-inch diameters. This joint configuration consists of a steel bell ring and a steel spigot ring which compress a rubber O-ring gasket when assembled. This joint is used in circumstances where other special features such as restraint are not required.

Deep Joint
Primary application: This bell and spigot joint is normally used for lined cylinder pipe 16 inches through 48 inches in diameter and embedded cylinder pipe 36 inches through 48 inches in diameter.

This joint is constructed in the same fashion as the standard joint described previously except the joint depths are greater to provide additional deflection capability. Joint depth for 48-inch and smaller pipe is 4-1/2 inches.

Under certain circumstances, this joint can be supplied on embedded cylinder pipe 54 inches through 96 inches in diameter. Check with a Price Brothers representative for availability. Pipe 54 inches through 96 inches with deep joints will have a joint depth 1 inch deeper than the standard joint.

Snap Ring^® Joint

Primary application: This patented joint design provides restraint for pipe diameters 16 inches through 60 inches.

Since 1973, Price Brothers has offered the Snap Ring joint for applications requiring a restrained joint. The outstanding feature of this joint is that it is easier to assemble than any other restrained joint.

The joint is completely self-contained and ready to install. Unlike other joint designs, which must be maneuvered into place and held while bolts are aligned and tightened, the Snap Ring calls for tightening just one 3/8-inch bolt. The Snap Ring enables one man to make the joint in just a few minutes using a simple speed wrench. At the same time, the Snap Ring joint also permits some deflection during installation for slight directional changes or corrections.

Following installation, the voids around the Snap Ring are filled with a portland cement grout. Under load, the grout will compress to allow for some settlement. In addition, the grout helps distribute the thrust load uniformly around the joint perimeter. The result is a superior restrained joint that saves installation time in the field.

Because the thrust-resisting components of this joint are surrounded by grout, they are protected from corrosive elements in the soil.

Harnessed Clamp Joint
Primary application: This joint provides restraint for diameters 66 inches and larger.

In addition to the Snap Ring® type restrained joint, Price Brothers also offers the clamp-type harnessed joint. This joint is restrained by a two-part harness clamp. The bottom half of the harness clamp is positioned under the joint prior to placing the next pipe length. After the pipe is installed, the top half of the clamp is positioned over the joint and secured to the bottom half by tightening bolts on each side. Grout is then poured into a grout band over the joint before the line is pressurized. The grout distributes any thrust loads around the joint as well as providing corrosion protection for the joint.

Harnessed Clamp

Testable Joint

Primary application: Allows testing of joints individually at time of installation.

When large diameter pipe is required, such as in power, industrial, water, and wastewater treatment plants, the Price Brothers testable joint is one of the most effective tools for testing each joint seal at the time of installation.

This particular joint eliminates the need to conduct a test on the completed line, therefore eliminating the need for bulkheads and the difficult and time consuming task of filling a large diameter line with water. Testable joints are available for pipe with diameters of 54 inches and larger.
