A method protects a field joint of a pipeline, where chamfered edges of thermally-insulating parent coatings on conjoined pipe lengths are in mutual opposition about a longitudinally-extending gap. The method includes manufacturing an hourglass-shaped inner layer around the pipe lengths, which layer may be moulded. The inner layer extends longitudinally along the gap between the chamfered edges and at least partially overlies the chamfered edges. A thermally-insulating solid insert is assembled from two or more parts to lie in the gap surrounding the inner layer, and pressure is applied radially inwardly from the insert to the inner layer. An outer layer of molten material is manufactured around the insert to form a watertight barrier and to form one or more melted interfaces with the inner layer. Corresponding field joint arrangements are also disclosed.

An insulating insert is positioned around a field joint of a pipeline to insulate the field joint. The insert comprises a longitudinal series of annular or part-annular filler segments of insulating material, curved about a longitudinal axis, that are each joined to one or more adjacent segments of the series by at least one link. The links may be webs, rods or articulated links. The links are flexible relative to the segments to facilitate bending of the insert along its length by enabling relative angular displacement between adjacent segments of the series.

An article of personal protective equipment, such as a protective glove, headgear, footwear, suit, or other protective device, wearable by a wearer for protecting the wearer against noxious agents, such as an article of chemical, biological, radiological and nuclear (CBRN) personal protective equipment. The article of personal protective equipment may comprise a plurality of regions that cover different parts of the wearer's body and have different properties, such as different levels of protection against noxious agents, breath ability, heat loss capability, dexterity, tactility, stretchability, and/or another function.

A method and an apparatus for producing a reinforcement mesh. Here, a reinforcement fiber strand is firstly saturated with a resin (H) and cured to form a cured, fiber-reinforced strand material. The strand material present as an endless material is then cut lengthwise into bars, which are then used as longitudinal bars or transverse bars for forming the reinforcement mesh. A connecting material is used at each intersection point between a longitudinal bar and a transverse bar and is dispensed in liquid form at the intersection point or is liquefied and then cured at the intersection point. A fixed connection is thus created between the longitudinal bars and the transverse bars at the intersection points. Between the intersection points, the longitudinal bars and the transverse bars have portions that are free of connecting material.

In a manufacturing method of an assembly, the assembly including a metal part and a pipe, the pipe including a material containing a resin, an adhesive is first adhered to an outer circumferential surface of the pipe and a metal part covering at least a portion of an outer circumferential surface of the pipe. Here, an area to which the adhesive is adhered on the outer circumferential surface of the pipe is defined as an adhesion area. Next, by a heat source provided inside the pipe, a target area is heated without interposing the metal part. The target area is located radially interior to the adhesion area and located on an inner circumferential surface of the pipe.

A method for quickly applying and spreading adhesive between substrates without leaving air bubbles. The method includes holding two substrates apart from each other with adhesive sides facing, a second substrate being positioned above a first substrate. The second substrate is suspended in a manner so as to cause a portion to warp towards the first substrate. After a liquid filler is applied between the two substrates, rollers are lowered onto the second substrate and moved so as to disperse the liquid filler between the first and second substrates. In accordance with the rolling of the rollers, end portions of the second substrate are lowered towards the first substrate.

An orthopaedic implant includes a main body having a surface with at least one bonding feature, at least one porous material having a plurality of pores, and a bonding material placed in the plurality of pores of the at least one porous material and the at least one bonding feature to form a bond between the at least one porous material and the main body.

A system of jointing reinforced thermosetting resin (RTR) pipe, including: a first RTR pipe with a spigot portion, the spigot portion having a first joining surface; a second RTR pipe with a socket portion shaped to receive the spigot portion, the socket portion having a second joining surface; and a cavity between the first joining surface and the second joining surface, the cavity formed when the spigot portion is push-fit into the socket portion; and an injectable/curable material located in the cavity. Additionally, a method of jointing RTR pipe, including the steps of: push-fitting a spigot portion of a first pipe into a socket portion of a second pipe, forming a cavity between the spigot portion and the socket portion; injecting a joining compound into the cavity; and curing the joining compound.

A system and method for welding thermoplastic components by positioning and moving a heated plate between the components to melt their respective faying surfaces, and as the plate moves, pressing the components together so that the melted faying surfaces bond together as they cool and re-solidify, thereby creating a composite structure. The plate has a heated portion which is positioned between and heated to melt a portion of the first and second faying surfaces. A manipulator mechanism moves the plate along an interface from between the portion to between a series of subsequent portions of the first and second faying surfaces, thereby welding the thermoplastic components along the entire interface to create the composite structure. The heated portion may contact the faying surfaces and melt them through conduction, or may be suspended between them and melt them through radiation and convection.

An insulating insert is positioned around a field joint of a pipeline to insulate the field joint. The insert includes a longitudinal series of annular or part-annular filler segments of insulating material, curved about a longitudinal axis, that are each joined to one or more adjacent segments of the series by at least one link. The links may be webs, rods or articulated links. The links are flexible relative to the segments to facilitate bending of the insert along its length by enabling relative angular displacement between adjacent segments of the series.
