The invention relates to an improved filament-reinforced tubular, and a method for providing such a tubular. A filament-reinforced tubular according to the invention comprises a tubular body (2), the tubular body comprising multiple fibre mats (10) encapsulated in a thermoset material (11), and is at least at one end provided with a male screw thread (3) comprising threading. According to the invention, the threading comprises a core member (12, 16). Furthermore, the threading comprises one or more fibre mats (13) that cover the core member. The one or more fibre mats are pulled between the windings of the core member by a positioning wire (14). The core member, the one or more fibre mats, and the positioning wire, are encapsulated by a, preferably thermoset, cover material (15), which cover material defines the shape of the screw thread.

A lock device for a coupling part of a piping or valve of a raw-material container or the like, capable of preventing looseness and erroneous operation of a coupling, and having favorable stability because the device is fixed as a force is applied to a direction of additionally fastening the coupling. The lock device is provided for achieving prevention of looseness of a coupling part (4) formed of a screwed member (20) and a screwing member (21) side, and includes a clamp member (42) for additional fastening attached to the screwed member side, a clamp member (41) for positioning and fixing attached to the screwing member side, and a screw member (43) for fastening the clamp members. The clamp members are fastened with the screw member (43), thereby being fixed to the coupling part while a force is applied to a direction of additionally fastening the screwing member side.

An improved anti-rotation device and connector assembly designed to prevent rotation of a first threaded portion of the connector assembly with respect to a second threaded portion of the connector assembly is provided. The anti-rotation device and connector assembly include features that guide and smooth the transition of the anti-rotation device into a position extending through the first and second threaded portions. The anti-rotation device may extend through a tab/groove interface between the first and second threaded portions, or the anti-rotation device may engage opposing interfacing edges of the first and second threaded portions along the length of the anti-rotation device. Once the anti-rotation device is installed through the first and second threaded portions, the anti-rotation device may prevent rotation of the threaded portions relative to each other.

An easy-to-install tap structure includes a tap body, a pipe joint and a connecting pipe for communicating the tap body with the pipe joint. The connecting pipe is arranged between the tap body and the pipe joint. When the tap structure is used for a wash basin, there is no need to connect a braided hose; in the process of replacing a tap, there is no need to replace the pipe joint and the connecting pipe, so that the pipe joint and the connecting pipe can be used many times; and when the tap is dismounted, the tap body can be directly rotated, and when the tap is mounted, the connecting pipe is directly adjusted to rotate until the water outlet of the tap is arranged in the correct direction.

Disclosed is an apparatus for connecting to a tube or a rod in a longitudinal axial direction of the tube or rod. The tube or rod is used in the assembly of a tube or rod string. The apparatus comprises an engagement member adapted to engage with an engagement 5 portion located at an end of the tube or rod. The apparatus also comprises an abutment member associated with the engagement member. The abutment member is adapted to abut an abutment portion of the tube or rod. The apparatus is adapted such that, when the engagement member is engaged with the engagement portion and the abutment member abuts the abutment portion, the abutment member can apply a locking force to the abutment 0 portion in the axial direction of the tube or rod, being a force that secures the engagement member to the engagement portion such that the tube or rod can be lifted and moved.
