Flexible Metal Tubes

Carniaflex offers a hundred standard flexible metal tubes that can be transformed/combined resulting in several thousand solutions varying in materials, diameters, lengths, ends, finishes, etc.

Carniaflex can soliisfy both the aesthetic and functional requirements of the hoses you need. The production range puts at your disposal the raw material (iron, brass, aluminum) or painted black (or other RAL color) or nickel-plated chrome or covered with black/white heat shrinkable sheathing; other metals/finishes are made at the Customer’s request. To identify the model with the right characteristics for the required performance, we provide standard drawings, codes related to diameters and stiffness with sealing/rigidity charts and prescriptions for proper use and safety.

Carniaflex needs the outside/inside dimensions of the hose identified in the code sheet (CF…………). Alternatively, in order to receive a suggestion from Carniaflex, there is a need to know the weight that is to be supported, the mode of use (table, wall, ceiling), whether cables are to be passed inside, and the length that is to be used (related to the sealing/rigidity charts). Therefore, to complete the product, it is necessary to know (in addition to the length) whether it is to have standard end terminals (10×1 threaded male/female) or to the Client’s design. If a raw metal product (iron, brass, aluminum) is not sufficient, a request can be made for the desired finish. In case you have a photo / drawing of the desired hose you can attach it to the necessary information.

All products for customers are coded in a unique and unambiguous way that makes it impossible to lose or misplace information even years later. Each product is assigned a coding and a bill of materials and where required or in more complex cases a drawing. Specific requests for testing, sealing or other needs that the customer desires are also documented so that the information is always on line and available to sales and production. For the protection of the customer and confidentiality of information, product codings are always different from customer to customer so as to prevent traceability between different customers.

Maximum cooperation is ensured to allow the finished product to be produced to the customer. Once the Carniaflex product has been identified and before starting production, for the customer’s functional testing and verification it is always suggested to request a sample, which normally if contained in a few standard blanks is free of charge with transportation paid by the customer.

By an inner spring made of Harmonic Steel (or upon request Stainless) and an outer coating of annealed metal (Iron, Brass, Aluminum) in its triangular shape interposes between the coils of the spring and with its friction generates the rigidity/flexibility of the product.

Iron is more prone to oxidation however it has the same functional characteristics as brass such as tightness and resistance to bending cycles. Aluminum cannot have the chrome or nickel-plated finishes but is particularly suitable for hoses that do not have to undergo much bending during their life cycle, in addition to being the lightest material. Brass is used universally for its excellent stability characteristics and versatility in applications subject to considerable stress (microphones, table lamps, examination lamps, etc.).

Being several hundreds of different terminals, once the product is identified in principle and/or upon customer’s request, pdf drawings of the required components are provided

Certainly. They are listed as a pdf sheet here and include: minimum recommended bending radii, Dangers or Warnings, Use Maintenance and Storage.

In this case it uniquely identifies the size of carniaflex hose 14.8×8.2mm. CF serves solely to avoid writing “Carniaflex hose” . The number that follows is to give the immediacy of the nearest outer dimension in millimeters to which we refer by avoiding the use of decimals (e.g.the 14.8 becomes CF15) . Each outer dimension/diameter is born with its ideal dimensions and an apropriate stiffness that we define Basic with the letter B, after which we have options to increase the stiffness (version R= Reinforced) or make it softer or Soft in movement (hence the letter S). In the Flex TYPES table of “codes and characteristics” we place in the column indicated with the equal sign “=” the type B. While on the left we indicate with the minus sign “-” the type S the decrease in stiffness and with the plus sign “+” the type R. Other letters give dlter indications in the same way. If the customer does not find the solution in the products shown in the table, then others already made are presented or an “ad hoc” product is developed that will be documented and specified to the customer but not published.
