A support table with an upwardly extending tubular neck engages the lower surface of the upper connector of the string to support the string while resting on a floor-level support. The neck is small enough for an elevator to close around the neck and still engage the outer portion of the lower surface of the connector....
A pipe joint which includes a bell and spigot and a split locking ring positioned within the joint between the outer face of the spigot and the inner face of the bell. The locking ring is expanded within the bell so that the spigot may be inserted into the locking ring and the bell and the locking ring is then contract...
A wire for gas metal arc welding containing 0.01 to 0.06 wt % of C, 0.10 to 0.60 wt % of Si, 0.9 to 3.1 wt % of Mn, 0.7 to 2.0 wt % of Cr, 0.005 to 0.06% of Ti, not greater than 0.08 wt % of Al and if necessary, 0.05 to 0.30 wt % of Cu, and the balance of Fe and unavoidable impurities. This wire improves the selective ...
An adaptor for extending a pipe through a barrier and securing the pipe therein which comprises a pipe segment having a leading end for insertion through the barrier and a trailing end to remain at the insertion side of the barrier upon insertion of the adaptor, each end being adapted to receive a pipe fitting. The lea...
In order to provide a heat pipe for transporting heat from an evaporation area to a condensation area, comprising a housing with housing walls, a capillary structure arranged in the housing and thermally coupled to the respective, corresponding housing wall in the evaporation area as well as in the condensation area, a...
The invention relates to a method for bonding an aluminum rib to a steel pipe, a surface coating material of the steel pipe being used as the bonding material, so that supplying a separate soldering material, for example, may be dispensed with. The invention additionally relates to a heat exchanger which comprises a un...
The present invention relates to a heat sink. The heat sink includes a casting, a block, heat pipes, and fins. The block is placed in a cavity of the casting. The heat pipes are composed of a straight heat pipe and two second degree curve heat pipes. The heat pipes are coupled to the casting. The fins are also coupled ...
Formation of metal pipes resulting from formation of metal silicide contacts are reduced or avoided. To reduce formation of metal pipes, an epitaxial layer is formed over the diffusion region on which the metal silicide contact is formed. The epitaxial layer reduces defects which enhances diffusion of metal atoms or mo...
A gasket and mandrel assembly, including a gasket having an annular main body portion with an anchor flange and a pipe sealing portion. The gasket is foldable between a folded position in which the pipe sealing portion is disposed substantially within the main body portion and an unfolded position in which the pipe sea...
The present invention relates to a polypropylene composition comprising a multimodal propylene random copolymer with at least one comonomer selected from alpha-olefins with 2 or 4 to 8 carbon atoms, wherein the polypropylene composition has a melt flow rate MFR 2 (2.16 kg, 230° C.) of 0.05 to 1.0 g/10 min, determined...
An exemplary flat heat pipe with an evaporator section and a condenser section includes a casing, and a first wick structure and a second wick structure in the casing. The casing defines a first vapor channel within the evaporator section. The first wick structure contacts an inner surface of the casing at the condense...
According to a laser welding method, an inert gas injection process and welding process are performed. In the inert gas injection process, inert gas is injected into an inside of a first metal pipe; and air inside the first pipe is discharged into the outside. In the welding process, a second metal pipe is irradiated w...
A pipe latch circuit comprises a reset signal generating unit which receives a read-write flag signal and a read period signal and generates a reset signal, wherein the reset signal is enabled upon entry into a write operation or after all data are outputted to an outside upon read operation, an input/output control si...
