摘要： A fastening member for joining together adjacent duct sections includes a head and a shank extending from the head, the shank having an unthreaded space adjacent to the head and a threaded portion extending from the unthreaded space, the threaded portion threadedly engaging a hole of an inserted corner plate positioned in flange of a first duct section. When the fastening member is fully inserted, the inserted corner plate positioned in the flange of the first duct section is retained within the unthreaded space.

摘要： The disclosure presents systems and methods for hot swapping pumps at a wellsite while minimizing the impact to the pumping operations. As one pump is swapped out, such as for maintenance, the remaining pumps in the set of pumps at the wellsite can continue pumping operations. In some aspects, the swapping of pumps can be performed by a user using a protection barrier to isolate the pump location where the pumps will be swapped. In some aspects, one or more of the steps to swap pumps can be performed through automation thereby minimizing danger to a user. In some aspects, the pump being located at the pump system can be primed and pressure tested prior to be located to improve the time to enable the pump for pumping operations.

摘要： This invention builds up on technical features and on the industry experience with the use of Merlin™ family connectors. In addition to friction, structural means utilized to transfer high torsional loads include dog-clutch teeth and may also include: interlocked thread systems, shear pins, keys and splines, all used in isolation or in arbitrary combinations. Static and fatigue bending load capacities of the connectors remain high, while the axial load capacities may or may not be high, depending on the design requirements. Connectors according to this invention can be built as new, carefully optimized designs. In some cases upgrading existing Merlin™ family connector designs to increase their torque transfer capacities may be also feasible.

摘要： A connector assembly (608) for a length of corrugated tubing (601) having an inner corrugated element (602) and an outer flexible sheath layer (603). The connector assembly (608) comprises a fitting (609) including a fluid-flow passage and an abutment surface (612) for the corrugated tubing (601) to seat thereon; axial loading means operably connectable to the fitting (609), the axial loading means including a connector (613) and a collet (610), the collet (610) having a radially inward protruding clamping element (611) for insertion into a trough (606) of the inner corrugated element (602), and a sheath-contact portion (625) for engaging the outer sheath layer (603), so that, when the connector (613) moves the collet (610) into engagement with the fitting (609), the collet (610) causes the corrugated element (602) to move onto the abutment surface (612) whilst maintaining engagement with the outer sheath layer (603). The sheath-contact portion (625) is axially positionable between the inner corrugated element (602) and the outer sheath layer (603) of the corrugated tubing (601), in use.

摘要： A sealing profile for embedding into a moulding of curable material, in particular a concrete or plastic moulding, and to a sealing arrangement comprising such a sealing profile. The object of the present invention is to provide a sealing profile for embedding into a moulding of curable material that can be anchored into the moulding in particular such that displacements of the seal in its seat occur to a significantly lesser extent, if at all, when installing or assembling the mouldings. The object is achieved by a sealing profile (1) with a profile region (2) having a profile region surface (4) which is directed towards the moulding (3) after embedding the sealing profile (1), wherein the profile region (2) has, at least in one subregion (6), a non-woven, felted or random fibre layer (5) which is fixedly connected to the sealing profile (1) and which extend beyond the profile region surface (4).
