Our T-Bolt Closure is designed expressly for nominal pressure applications. It is less expensive and much more satisfactory than blind flanges and job fabricated closure devices. Economically priced and low initial cost are especially attractive features of the T-Bolt Closure. There are no additional expenses for hinges, hoists, davits, etc., as the closure is fully assembled when shipped. Furthermore, installation-labor charges are held to a minimum; a single butt weld joins the closure to the vessel nozzle.
