T-Bolt Closures

Tube Turns® exclusive T-Bolt Closure is designed expressly for low- to medium-pressure applications. It is lighter, less expensive and much more convenient than blind flanges and job-fabricated closure devices.

Economical price and low initial cost are especially attractive features of the Tube Turns® T-Bolt Closure. T-Bolt Closures are available in horizontal (opens like a car door) and vertical (opens like a car hood) configurations.

A complete unit normally costs less than the component parts for a blind or slip-on flange combination. There need be no additional expenses for hinges, hoists, davits, etc., as the closure can be fully assembled when shipped. 

Furthermore, installation-labor charges are held to a minimum; a single butt weld joins the closure to the vessel, vessel nozzle, or pipe.

Compact design, light weight, and simplicity of construction and operation are keynotes of the Tube Turns® T-Bolt Hinged Closure. 

The closure consists of a thick elliptical head hinged to a matching hub, a self-energizing O-ring and a suitable number of T-bolts to effect and maintain a tight seal.

For most services, the standard materials - carbon steel and a "Buna-N" O-ring-are satisfactory. Other metals and elastomers are furnished on special request. 

The T-Bolt Hinged Closure is opened quickly and easily. The operator merely loosens the T-Bolts until they clear the holding lugs and allow the head to be swung open on its hinge. 

Complete, unrestricted access is provided; too, since the standard head stop permits a full 180° opening. Other convenient options include breakover handles and camlock wrenches that allow the T-Bolt closure to be opened and sealed without tools.
