A girth weld coating machine has an application head rotatable about a pipeline. A reservoir of coating material is carried on the application head and progressively dispenses coating material on to the girth weld. The coating material is applied to the pipe surface by a roller to spread and distribute the coating over the surface.

Provided is a flexible tube production apparatus capable of shortening the length of a resin layer in which the mixing ratio between two kinds of resins changes. The flexible tube production apparatus includes: two extruders extruding resins different from each other; two valves provided corresponding to the two extruders, respectively; a kneading mechanism kneading the resins supplied from the two extruders via the two valves; a die extruding the resins kneaded by the kneading mechanism; and a control device controlling the two valves to switch from a first state where one extruder and the kneading mechanism communicate with each other and communication between the other extruder and the kneading mechanism is cut off, to a second state where the other extruder and the kneading mechanism communicate with each other and communication between the one extruder and the kneading mechanism is cut off, when the flexible tube is extruded.

A method for producing hoselines having at least the following working steps: a) providing a hoseline or pipeline blank (1, 2, 3) of at least one elastomeric and/or thermoplastic base material in a production device, while reinforcing elements may be embedded in the base material; and b) introducing an RFID structure (4, 4A, 4B, 4C) into the outer layer (3) of the hoseline or pipeline blank (1) in the axial direction parallel to the longitudinal axis of the hoseline or pipeline blank (1) and synchronously with the feed rate of the production device, the RFID structure having at least one carrier (4A) and the RFID structure (4, 4A, 4B, 4C) having RFID chips (4B) securely arranged on the carrier (4A) at predetermined spaced intervals.

A method for manufacturing a lightweight cowl crossbar includes: producing an inner pipe, laminating a plurality of composite material layers wound around the inner pipe, and extruding an outer pipe on the winding layer, in which the plurality of composite material layers adjacent to each other are wound in different directions.

A limb for a breathing circuit manufactured from very thin walled polymer materials has an elongate axial reinforcing spine lying freely inside the conduit and fixed to each end connector. The spine is laterally compliant but axially stiff. The spine provides resistance to tensile and compressive loads on the conduit, including that induced by prevailing internal pressures.

It is disclosed a method for the production of a sealing module (1) for a pipe or a cable, the sealing module having a hollow body (10) and a plurality of inner layers (11a-11h) superimposed one to the other provided within said body (10), the layers (11a-11h) being removable one from the other to define the size of the cross-section of a housing (14) extending between two opposite surfaces (S1, S2) of the sealing module to house cables or pipes of different sizes, wherein said plurality of layers (11a-11h) are made of a thermoplastic material, or both said body (10) and said plurality of layers (11a-11h) are made of a thermoplastic material. It is also disclosed an apparatus for the production of a sealing module, and a sealing module made of thermoplastic material.
