Dixon DBV-VB300 Grooved Bolted Clamp is a 3-inch ductile iron fitting designed for secure pipe connections. This hose fitting provides reliable performance in industrial applications, featuring a durable grooved design for easy installation and a tight seal.

Applications

Grooved clamps are often used on pipe connections on dry bulk tankers in place of welding offering the ability to adjust, change or replace pipe sections without the need for a permanent joint such as a weld.

Construction

• Aluminum body
• Steel bolts/nuts
• FKM-B seals

Features

• Precision forged to provide an exact fit and great appearance
• Use of lock nuts prevents clamps from loosening in high vibration applications
• Leak-tight connection
• Lightweight yet rugged. Unlike steel groove clamps that secure pipe ends with high clamp force against the tubing walls, the Dixon bolted clamp takes the full bolt force and locks in the groove of the tube preventing distortion of the tube diameter.

How It Works

The two pipes are butted to one another each pipe has a groove that runs the circumference of the pipe exterior. The grooved clamp has ridges that lock into the two pipe grooves and a gasket is compressed to the pipes to create a leak-tight seal.

Note

• Supplied clamp gasket must be installed prior to use. Ships separately.
• Replacement gaskets are available.

Safety Notes

• Torque the bolts until metal to metal contact occurs at the bolt pads (about 20 ft-lbs). Bolts must be tightened evenly to prevent gasket pinching and clamp breaking. DO NOT tighten one side then the other. Over-torquing will not improve sealing and may result in failure of the clamps. DO NOT torque bolts over 30 ft-lbs.
• Intended for tank truck applications only
