"Improving the ductility of welded connections in

This paper presents an effective and economical solution that significantly increases the bending ductility of welded connections in rectangular hollow sections (RHS). It can be applied to new as well as existing structures. It involves the use of extra layers of weld on the tension flange of the connected RHS. Laboratory test results are presented to demonstrate that the solution Case Studies on the Use of Thermal-Mechanical Finite The hollow-lip designs inherently offer more flexibility and can generally accommodate more differential radial thermal expansion between mating flanges. This paper highlights a case study of a high-pressure heat exchanger where the shell side-to-tube side girth flange joint is fitted with a weld

Development of advanced CRDM without canopy seal welds

May 01, 2002 · The CRDM latch housing is threaded to the head adapter flange and seal welded with the canopy lips, while the other end of it is threaded to the rod travel housing and seal welded with canopy lip. The former is called the bottom canopy seal weld and the latter is the middle canopy seal weld. Grayloc Product Catalog - WOODCO USAassembly, the seal ring lips deflect against the inner sealing surfaces of the hubs. This deflection elastically loads the lips of the seal ring against the inner sealing surface of the hub, forming a self-energized seal. Clamp Assembly Designed to provide nearly 360° clamping contact with the hubs. A relief notch in the center of the clamp Perimeter weld flanges - Kimball Physics, Inc.Oct 09, 1997 · A method for welding a hollow metal flange having a weld lip at one end thereof to a hollow all-metal vacuum manifold body, said hollow metal body having an interior vacuum side surface and a spherical exterior surface, and having at least two branch ports extending between the interior surface and the exterior surface, comprising locating said hollow flange in each said port with a

The jamb portion, 21, is a three-sided frame made up of hollow sheet metal including a strike lip, 22, a moulding finish, 23, and an overlapping portion, 24. This jamb portion is made up into a three-sided frame by welding or otherwise securing the side jambs and top jamb together at the upper corners. WELD RING GASKETS. - SealmaxWeld ring gaskets with additional auxiliary gasket are used when:The pressure test is done without welding only with the auxiliary gasket The ange connection is opened several times during start up Welding is only carried out if the auxiliary gasket does not achieve tightness The use of weld ring gaskets with hollow lips is recommended Weld Preps and Backing Bars Tekla User AssistanceFeb 05, 2021 · This Custom Component creates a circular backing bar for round hollow members. This detail can also be used in Pipe Weld Prep (Conx) or Pipe Weld Prep (Detail) shown above. This Custom Component creates 1 backing bar on the underside of a wide flange prep. This detail can also be used in Weld Prep Beam shown below.

Weld Ring Gaskets - Möller-Metalldichtungen GmbH (Englisch)

Weld ring gaskets (according to DIN 2695) always form a pair. These are individually welded onto the flange surface and welded together. This sealing technique achieves absolute gas tightness. There are two types of weld ring gaskets:With hollow lip:profiles WRG-WR and WRG-WRL; Without hollow lip:profiles WRG-FG and WRG-WL Welding between a thick solid rod to tubular hollow Sep 18, 2020 · RE:Welding between a thick solid rod to tubular hollow section 1503-44 (Petroleum) 18 Sep 20 16:52 Why not internally bore the end of the rod, such that it leaves a lip of the same width as the tube wall where they will be joined.Weld ring gaskets KLINGER EngineeringThe hollow lip optimises the state of tension in the gasket seam between the two halves of the weld ring. If a closed design and non-destructive testing are deemed to be of value, or if the assembly expense is to be significantly lower, we are happy to design our type A42 weld-ring
