Bolted flat covers

In accordance with hsted standards, blind flanges may be used at their pressure-temperature ratings. The minimum thickness of nonstandard bhnd flanges shall be the same as for a bolted flat cover, in accordance with the rules of the ASME Boiler and Pressure Vessel Code, Sec. T11. [Pg.985]

When d >. 5D design the bolted flat cover as an ordinary weld neck flange. [Pg.510]

Unstayed flat heads and covers can be designed by very specific rules and formulas given in this subsection. The stresses caused by pressure on these members are bending stresses, and the formulas include an allowance for additional edge moments induced when the head, cover, or blind flange is attached By bolts. Rules are provided for quick-opening closures because of the risk of incomplete attachment or opening while the vessel is pressurized. Rules for braced and stayed surfaces are also provided. [Pg.1024]

Flat heads or covers are used widely as closures to pressure vessels. They are either integrally formed with the shell, or may be attached by bolts. Figure 6.5 shows some typical designs of covers. [Pg.83]

A torispherical tlLshcd closure or a spherical dishetl flat plate may be combined with a bolting ring to produce a dished cover, as shown in Fig. 13.7. [Pg.260]

Determine the llnckness t f a flat cov er plate such as the one shown in detail (f a Fig. 13,8 which might la used as a ut)slitiite for tlie dished cover described in problem 4, using the same dimensions and specifiGdtidns for gasket, bolts, and materials. [Pg.267]

One of the more common types of closures for pressure vessels is the unstayed flat head or cover. This may be either integrally formed with the shell or welded to the shell, as shown in Fig. 10.1 or it may be attached by bolts or some quick-opening device as shown in Fig. 10.2. It may be circular, obround, square, rectangular, or some other shape. Those circular flat heads that are... [Pg.146]

In the ASME Code, VIII-1, and Section I, the minimum required thickness of circular, unstayed flat heads and covers without bolting are calculated by the following ... [Pg.149]
