Tubes - Import export

Double tube heat exchangers (also known tube-in-tube) are designed whereby one tube is concentrically positioned within a larger tube. The double tube composition allows for unrestricted flow of product, making it the ideal heat exchanger for viscous products. The product flows through the inner tube and the service fluid flows through the surrounding shell.

Two and three-way valves are used for transfer of liquids or gases in order to release the flow, to block it or to change its direction.

Aluminiumwerk Unna AG is specialised in the production of Aluminium tubes. The Aluminium tubes are extruded on site using two possible methods. These are either Seamless extrusion or Porthole extrusion. It is quite simple to distinguish between the two extrusion methods. In seamless extrusion, a mandrel is positioned and fixed inside the extrusion die, creating the inner contour of the tube. In porthole extrusion, the mandrel is fixed and is supported by a number of integral bridges affixed to the outer portion of the extrusion die.

Cylindrical T hose connector to connect hoses.

Rain protection set 12256 consisting of an extension made of PVC and a black protective cap made of soft PVC for the floor sockets 7501A, 7601A, 7602A, 7604A and 7701AW. The rain protection set offers ideal protection against rain with plugged-in connections. Use: Proper installation and proper use is required. The seals must be cleaned of dirt regularly and the products must be checked to ensure they are in perfect condition.

Top tube 12253 made of PVC for the floor sockets 7601A, 7602A, 7604A, 7701E, 7701M. For use in wet conditions when plugged in.

CheMobil made of PMP/TPX can be used for many substances due to its good chemical resistance. Not suitable for strong acids, alkalis and solvents. CheMobil can be steam sterilised. Flow indicators give precise visual indication of the flow velocity of liquids or gases being transported through hose connections. The flow indicator with impeller functions in both directions and in any position. The impeller starts to rotate at a flow rate about 150 ml/min (liquids).

Easy-Click closure - stop-it can be opened and closed in any position - without tiresome screwing on and off. High quality material - stop-it made from the heat resistant and chemical resistant plastic PVDF. The clamp is galvanised steel. The hose clip can be used wherever the flow in hoses with liquids or gases needs to be regulated or stopped. Stepless flow regulation: With the hose clip stop-it's knurled screw, a stepless, delicate flow regulation or complete stop of the flow are possible, even for existing hose connections. The hose is compressed over a wide area against the sturdy steel hook in order to prevent it from being damaged.

Retaining valve with embossed directional arrow or printed in black. With conical nozzles. Various uses.

The materials steel and aluminium ensure that the tubing clamp stop-it metal is extremly heat resistant and sturdy. The tubing clamp is available in four different sizes, for hose diameters up to max. 30 mm. The tubing clamp can be used wherever the flow in hoses with liquids or gases needs to be regulated or stopped. Stepless flow regulation: With the tubing clamp stop-it's knurled screw, a stepless, delicate flow regulation or complete stop of the flow are possible, even for existing hose connections. The hose is compressed over a wide area against the sturdy steel hook in order to prevent it from being damaged.
