An insulated subassembly for connecting pipelines, containing two insulating half shells made from an insulating plastics, in each case a housing half shell surrounding an insulating half shell, wherein the housing half shell surrounds the outer peripheral surface of the insulating half shell, and at least one hinge connecting the housing half shells, wherein the insulated subassembly contains at least one coupling, preferably quick couplings, positively surrounded by the insulating half shells, and integral closure elements are arranged on the housing half shells.

Insulated subassembly

A fitting for connecting a secondary plastic pipeline of a double pipe system containing two half-shells composed of plastic, wherein in each case each of the half-shells has an integrated heating wire, wherein the heating wire is arranged in each case in the regions of the connecting pieces and the heating wire has several meandering windings, wherein the heating wire is arranged in each case in a groove provided for this in the half-shell and the connecting elements which connect the two half-shells, characterized in that the fitting has distance elements arranged on the inner circumference of the half-shells for concentric arrangement of the fitting with respect to a primary pipeline.

Weldable half-shell

A length compensator for pipelines, preferably plastic pipelines, containing two connecting components, preferably made from plastic, a compensating element made from an elastic material, preferably a thermoplastic elastomer (TPE), and a supporting pipe, wherein the compensating element is arranged between the two connecting components and the compensating element ends are connected to the connecting components, wherein the outer lateral surface of the compensating element is suitably encompassed by the inner lateral surface of the supporting pipe around its entire circumference, wherein the supporting pipe has a circular cross-sectional area and the compensating element expands and contracts exclusively in the axial direction.

Length compensator

A method and device for stripping the insulation from and peeling pre-insulated pipe ends by means of a peeling and cutting tool.

Method and device for stripping the insulation from pre-insulated pipe conduits

A paring and cutting tool, and a therewith associated method, for the stripping and paring of pre-insulated pipe ends, in particular of the outside diameter of the medium-conveying pipe comprising a clamping unit for the reception of the pipe end, a guide unit for the feed movement of the stripping and paring unit, wherein the guide unit extends through the clamping unit, a cutting unit for separating the outer pipe and the insulating layer, a carrier and a stripping and paring unit, wherein the stripping and paring unit has a paring element, preferably a paring blade, and a stripping element, preferably a stripping contour, for the simultaneous stripping and paring of the pipe end, in particular of the medium-conveying pipe end.

Paring and cutting tool

The invention relates to a method for producing a tubular hollow body () with at least three pipe openings, partly or completely consisting of plastics material. It is provided that a lost core pipe (), which has a connection opening () on each of its ends and has at least one docking opening () along its length, is produced, that the core pipe () is introduced into a cavity of a mold, with two non-lost core pieces () being arranged with one of their ends () respectively against the connection openings () in a sealing manner and a non-lost core part () being arranged with one end against the docking opening () in a sealing manner, in that plastics material () is then introduced into the mold cavity to encapsulate the core pipe (), the core pieces () and the core part () and that, once the plastics material () has cured, the core pieces () and the core part () are withdrawn from the hollow body () created. The invention also relates to a corresponding hollow body ().

Method for producing a tubular hollow body, and tubular hollow body

A bayonet fastening which can be used to connect two pipeline components, in particular connection elements. The pipeline components which are to be connected respectively comprise a cylindrical receiving part () and the second pipeline component comprises an insertion part () which can be introduced into the receiving part. A clamping ring () is arranged on the outer diameter of the insertion part and the receiving part can be pushed onto said clamping ring. The bayonet fastening can be locked by rotating the receiving part and the insertion part in relation to one another.

Bayonet fastening

The invention relates to a method for producing a tubular hollow body () with at least three pipe openings, partly or completely consisting of plastics material. It is provided that a lost core pipe (), which has a connection opening () on each of its ends and has at least one docking opening () along its length, is produced, that the core pipe () is introduced into a cavity of a mould, with two non-lost core pieces () being arranged with one of their ends () respectively against the connection openings () in a sealing manner and a non-lost core part () being arranged with one end against the docking opening () in a sealing manner, in that plastics material () is then introduced into the mould cavity to encapsulate the core pipe (), the core pieces () and the core part () and that, once the plastics material () has cured, the core pieces () and the core part () are withdrawn from the hollow body () created. The invention also relates to a corresponding hollow body ().
