The vacuum space is sealed at the lower end of the can by a threaded, flanged stud which mates with the internal threads of the retaining member for the stack of stainless steel washers. The flange on the stud is soft soldered to the end of the retainer and a polytetrafluoroethylene disk located between the upper end of this stud and the lower end of the stud which supports the stack of washers absorbs some of the shock produced when a specimen fractures in the cryostat. 

Relaxation is an important example of a creep phenomenon encountered in practice. Bolts, studs, flanges, and springs of all kinds are subject to relaxation when used at high temperatures. These members are loaded to a stress that must be maintained for proper functioning. If relaxation occurs, the stress decreases. Thus bolts can become loose so that bolted joints develop leaks after operation at elevated temperatures.

Nobody knows why this had been done. Probably one nut was tighter than the other, and in attempting to tighten this nut, the whole stud was screwed through the second nut. Whatever the reason, it produced a dangerous situation because the pressure on different parts of the flange was not the same. 

Type of hold-down arrangement flanged (slip on, W eld neck, screwed, stud) union, screwed, or special. 

Minimize heat losses from the reactor plenum and the transfer line. Heat loss will cause condensation of heavy components of the reaction products. Insulate as much of the system as possible when insulating flanges, verify that the studs are adequate for the higher temperature. 

For all flange joints, the bolts or stud bolts used shall extend either completely through the nuts or one thread short of the full nut. 

Note For pumps with flange and pressure ratings in excess of the minimum values in 2.2.2, the gland stud size and circle may increase. Larger studs shall be furnished only if required to meet the stress requirements of Section VIII or Section II of the ASME Code, or to sufficiently compress spiral wound gaskets in accordance with manufacturer s specifications. 

Flanged openings shall be provided with metal closures at least 5 mm (0.19 in.) thick, with elastomer gaskets and at least four full diameter bolts. For studded openings, all nuts needed for the intended service shall be used to secure closures. 

FJanscbgescfioss (Ger)(FIange Projectile), also called "Squeeze-bore , or "Littlejohn was a subcaliber projectile provided with a a flange and three hollow studs as shown on Figure and described in the TM 9—1985—3, p 360... 

The principal advantage of die "flange projectile in comparison to die other subcaliber projectiles was that it had no parts to be discarded, because the hollow stud and die flange were easily depressed when die projectile passed from die rifled section of die gun to the smaller caliber smooth bore extension... 

Once the disc insert is lapped or replaced, carefully dean the nozzle surface If defects are found, it is recommended that the nozzle be removed from the body. This can be cumbersome in some valve designs and is not recommended if not absolutely necessary. To remove the nozzle, turn the valve body over, taking care not to damage the bonnet studs. Turn the nozzle counterclockwise by using the wrench flats (if any) on the nozzle flange or a round nozzle wrench designed to clamp onto the nozzle flange... 

All SCL produets ean substitute for sawn timber produets in many applieations. LVL is used extensively for seaffold planks and in the flanges of prefabrieated I-joists, whieh takes advantage of its relatively high design properties. Both LVL and PSL beams are used as headers and major load-earrying elements in eonstruetion. LSL and OSL produets are used for band/header joists in floor eonstruetion and as substitutes for studs and rafters in wall and roof eonstruetion. SCL produets are used in non-struetural applieations, e.g. the manufaeture of windows and doors. 

Ribs and gussets (reinforcements), studs (usually round), mounting supports (any shape), hubs (usually round), ejector pin extensions, flanges, threads, and undercuts. 

Transverse continuity may be provided by using an in situ concrete connection containing looped reinforcement cast into the slabs (Fig. 8.3) an alternative arrangement using folded steel plates may also be used (Fig. 8.4). The primary shear connection is provided by shear studs welded alternately to the soffit plate and the longitudinal beam flange. It is important that the precast/i situ construction joint occurs well away from the beam flange to avoid excessive rotations and subsequent slab distress under traffic loads. 

The closure head is available for inspection whenever it is removed, and its removal makes available the vessel closure flange, the flange-to-shell weld, closure stud holes and ligaments, and the closure studs and nuts. Each control element drive mechanism is removable as a unit through a closure at the top of its housing. Since many of the reactor vessel closure head examinations are done from the underside of the head, the head laydown area provides access for a man to work under this component using manual techniques.

The calculations for a studding outlet will vary from standard flange calculations because these flanges are not hubbed or hubless. However many of the loads and moments calculated in a standard flange still apply. The bolt load calculations and gasket calculations are identical.
