Description

[0001] A NEW DESIGN TO INCREASE THE STRENGTH OF INDUSTRIAL PIPE ELBOWS AND EXTEND THEIR USAGE LIFE

[0002] Technical Area

[0003] This invention is about a pipe elbow design that aims to prevent wear and deformation caused by the fluid passing through the inner surfaces of industrial pipe elbows, which can be used in oil refineries or greenhouses, after the assembly phase.

[0004] Background

[0005] It is inevitable that many turning points will arise in the assembly and laying processes of welded and / or seamless industrial pipes, depending on the structure of the line.

[0006] In state-of-the-art applications, the most commonly used method is to support the brackets mounted on the turning points from below with struts fixed to the ground.

[0007] It is inevitable that these struts are fixed to the elbow by welding.

[0008] The visual of current applications is presented as Figure 1.

[0009] Technical problems to be solved

[0010] In the state-of-the-art applications, when the struts fixed to the ground are welded to the elbows, thinning inevitably occurs at the elbows.

[0011] These thinnings cause the fluid passing through the pipeline to deform the inner part of the convex surface of the elbow, which is thinned due to welding, and cause explosions and leaks over time. This is the first problem awaiting solution.

[0012] In some applications, increasing the wall thickness of the elbows has been tried to solve this problem. It is known that such designs not only increase the construction costs of elbows, but also cause other problems such as being excessively heavy and incompatible with standard flange diameters.

[0028] 4) Metal sheet

[0029] Detailed Description

[0030] The feature of the self-slat Elbow (2) that is the subject of the invention is that instead of increasing the wall thickness of the entire elbow, it has a design that enables it to carry the vertical weight of the line while strengthening only the section of the structure that is exposed to the horizontal impact force of the fluid passing through it.

[0031] To achieve this, unlike known production methods, instead of increasing the wall thickness of the elbow or producing it in standard sizes and connecting it to the Support leg (3) with an external Metal sheet (4), during the production phase the Elbow (2) is given an extra thickness only in the 90° rotation area that is exposed to load and pressure. The problem is solved by giving extra thickness in the form of a Metal sheet (4).

[0032] As explained in the above section, during the use of the external Metal sheet (4), the Elbows (2) produced in standard diameter and wall thickness become thinner in the area where they are exposed to the most pressure and load.

[0033] When the wall thickness of the entire Elbow (2) is increased, there is a problem in adapting to the diameter of the Flange ( 1 ). With the subject invention i.e. the Elbow (2); the Flange (1) complies with the diameter standards and at the same time, it can be used in industrial pipelines without any problems for long periods of time with its Metal sheet (4) contained in its monoblock body.

[0034] It is presented as a product that can be used over long periods of time, is lightweight, cost- effective and has high strength.

[0035] Industrial Applications

[0036] The dimensions of the Elbow (2) which is the subject of the invention are included in the drawing sheets, and these dimensions are within the scope of protection of the application in terms of safety and reliability in the use of the elbow. The design and production of the Elbow

[0037] (2) can also be done with 3-D printers, and the variables in the design (wall thickness, Metal sheet (4) area) can be easily adapted to the desired dimensions and values.

Claims

AMENDED CLAIMS received by the International Bureau on 26 August 2025 (26.08.2025)

1. [Amended] The invention is an Elbow (2) suitable for use in industrial pipelines including a Metal sheet (4) obtained by increasing the wall thickness in the range of 45°to 120° rotation section, which is exposed to the vertical load of the line and the horizontal impact force of the fluid passing through it.

2. [Unchanged] The feature of the Elbow (2) in Claim 1 is that it has a monobloc body with the Metal sheet (4) it contains.
