DE202006018381U1 - Pipe clamp with reduced heat transfer is bent from flat profile and has a reduced contact surface on the side facing the pipe compared to conventional pipe clamps - Google Patents

Abstract

The pipe clamp conforms to or is similar to DIN 3567, is bent from flat profile and has a reduced contact surface on the side facing the pipe compared to conventional pipe clamps. The pipe clamp has one or more cut-outs (2) with a depth (1) of at least 0.1 mm up to 15 mm, generally 0.5 mm.

Description

clamps are produced in many different dimensions to meet the different requirements. Are standardized they e.g. in DIN 3567. Feature of this and other pipe clamp specifications is the use of flat profiles caused by hot or cold deformation be brought into the appropriate form. Put these clamps It feels like a flat band around the tube and therefore has a large contact surface.

With such clamps pipes are held and pipe supports (or the function of Rohrhalterung gleichzusetzenden parts) attached. Through this contact wanders, regardless of the isolation of the Pipe, heat from the pipe to the environment. It creates a permanent heat loss at this point.

insulating inserts to avoid the described heat loss, from substances such as e.g. Rubber or asbestos substitutes have limitations in strength and / or in temperature.

In some cases Clamps are made of only 1 mm to 2.5 mm thick stainless steel sheet used, which in cross section no flat but a trapezoidal profile to have. The contact surface Although reduced, but the strength is significantly reduced. Therefore, the use is limited to small and light pipes.

Of the The invention is based on the problem of, e.g. DIN 3567, pipe clamp, to change so that at the same or almost the same strength, the heat dissipation is markedly reduced becomes. The invention described in the patent is a pipe clamp with reduced contact surface to the pipe. The reduction of the contact area, e.g. to 1/3 of the usual Area, is defined by one or more recesses of shallow depth, e.g. 0.5 mm, reached. This recess (s) will be in the range of Attaching the clamp to pipe supports (or the function made of pipe support equal parts) made.

In the drawing 1 Pos. 2 , a recess is shown as an example. In the drawing 2 Pos. 2 , two recesses are shown as an example. The depth of the recess is in the drawings 1 and 2 with pos. 1 characterized.

With appropriate design, eg adapted to the material thickness recess, leakage of the recess before the beginning of the "clamp ear" in the drawings 1 and 2 with pos. 3 characterized, the pipe clamp is only slightly weakened, but the heat transfer significantly reduced. This slight weakening may possibly be within the general tolerances of these parts and thus irrelevant.

With the invention is achieved that at each pipe diameter, without or with only a small reduction of the absorbable forces of the Compound of e.g. Pipe clamp to DIN 3567 to the pipe, a reduction the heat losses is reached.

Claims (4)

Pipe clamp with reduced heat transfer is characterized in that the pipe clamp, for example and / or similar to DIN 3567, is bent from a flat profile and, compared to the usual area, reduced contact surface on the pipe side facing. Clamp according to protection claim 1 is characterized in that one or more recess (s), a depth of at least 0.1 mm to a maximum of 15 mm, usually 0.5 mm depth / have. In the drawing 1 Pos. 2 a recess is shown as an example. In the drawing 2 Pos. 2 Two recesses are shown as an example. The depth of the recess is in the drawings 1 and 2 with pos. 1 characterized. Pipe clamp according to one of the preceding claims characterized in that the recess (s) in the region of Clamp is / are in which the attachment (s) to the pipe support, or the function of Rohrhalterung gleichzusetzenden parts occurs. Pipe clamp according to one of the preceding claims for protection is characterized in that the recess (s) before the beginning of the bow to the "clamp ear", in the drawings 1 and 2 with pos. 3 characterized, phased out and / or end.
