A tool for fixing a protective textile sleeve about an elongate member contained therein and method of use thereof is provided. The tool includes a clamp assembly having opposed clamp members attached to one another for pivotal movement relative to one another between an open state and a closed state. The clamp members have clamping surfaces, wherein at least one of the clamping surfaces has at least one outlet. A fluid source is arranged in fluid communication with the at least one outlet, and a heat source is configured to heat fluid from the fluid source to create steam. The steam is dispensed outwardly from the at least one outlet to cause an adhesive on the sleeve to become activated to bond with an adjacent abutting surface.

The invention relates to a method for producing a tank from thermoplastic material, comprising the following method steps: extruding or providing a hose-like parison composed of plasticized thermoplastic material, and dividing and spreading the parison into two areal extrudate webs, or extruding or providing two parisons in web form, laying-in and molding the parisons in recesses of a multi-part blow-molding tool using differential pressure, wherein the recesses of the blow-molding tool delimit a mold cavity, punching out, or cutting out in a circular shape, at least one opening in at least one shell-like intermediate product, wherein the opening is produced by way of a punching or cutting tool which penetrates through a wall of one of the shell-like intermediate products, wherein in a second separate method step, a first attachment element of a line connection or of a line arrangement is welded, at the mold cavity side, to the wall of the shell-like intermediate product, in such a way that an encircling weld collar of the first attachment element sealingly surrounds the opening, joining the shell-like intermediate products to form a tank, and removing the tank from the blow-molding tool, and connecting a second attachment element, which is complementary to the first attachment element in the context of a plug-type connection, to the first attachment element, wherein the plug-type connection is produced within the contour of the tank as defined by the tank wall.

A container and handle system includes a container including a flange and a top load strength in a range of less than 25 lbf. A handle includes at least one radially oriented tab movable to define a first diameter being greater than a diameter of the flange and configured to facilitate translation over the flange. The at least one tab is biased to a second diameter that is less than the flange diameter such that the at least one tab engages the flange to fix the handle with the container. Packaging products, containers, handles, tooling, applicators and methods are disclosed.

Provided are methods for heat curing of various materials, such as heat curable materials or more specifically potting compounds, which are disposed within cavities with limited access to these materials. Also provided are curing for executing such methods. In some embodiments, a heat curable material disposed within a cavity may be heated by a heating rod protruding into the cavity or through the cavity. The heating rod is thermally coupled to the heat curable material and is used to transfer heat to the heat curable material. For example, the heating rod may include a resistive heating element. The heating element may be positioned in such a way that the heat curable material is selectively heated within the cavity without significant heating of surrounding components. In some embodiments, the heating rod may be also used to compress the part containing the cavity or a stack including this part.

A method of welding a gasket to a spigot portion of a pipe section is described. The method includes supporting the gasket in a recess on the spigot portion of the pipe section. The gasket includes a seating portion and a sealing portion. The sealing portion includes a first shoulder portion and a second shoulder portion. A first bonding portion extends from the first shoulder portion and a second bonding portion extends from the second shoulder portion. The first bonding portion and the second bonding portion are provided to bond the gasket to the spigot portion. The method further includes heating a portion of the gasket and an adjacent surface of the spigot portion and applying a force onto the portion of the gasket following the application of heat to fuse the gasket onto the spigot portion.

A welding assembly having a support part, of a material that is absorbent to a laser radiation, and an attachment part, with at least one collar piece that is transparent to the laser radiation. The support part and the at least one collar piece have a first joining area and a second joining area, which together form a joining region. The surface contours of the joining areas deviate from one another, and so, when the welding assembly is being joined together, the collar pieces are deformed while they come to bear closely against the support part. The attachment part is formed in such a way that it can be taken up by a receiving mandrel and positioned with respect to the support part and pressed against it by means of the receiving mandrel.

A process for producing a thermoplastic composite pipe, where the process includes: a) providing a tubular liner having a wall containing a thermoplastic polymer A in the region of the outer surface; b) providing a tape containing reinforcing fibres in a matrix containing a thermoplastic polymer B, where polymer A and polymer B are different; c) applying a film or a composite which is produced in d) and is composed of a film and a tape provided in step b) to the tubular liner, with melting of the outer surface of the liner and of the contact surface of the film either beforehand, simultaneously or thereafter, d) applying the tape provided in b) to the outer surface of the film, with melting of the outer surface of the film applied and of the contact surface of the tape either beforehand, simultaneously or thereafter,
where the surface of the film which is brought into contact with the liner contains a moulding compound containing polymer A to an extent of at least 30% by weight, and the opposite surface of the film contains a moulding compound containing polymer B to an extent of at least 30% by weight.

A process for producing a thermoplastic composite pipe is provided. The thermoplastic composite pipe thus produced contains a liner, two or more composite layers composed of tape laminas, and a single- or multilayer intermediate lamina arranged between different composite layers. Composite formation between identical polymers in the process achieves improved adhesion. The thermoplastic composite pipe is especially suitable for offshore applications in oil or gas production.
