Abstract

A connecting system is provided for detachably connecting a first pipe end to a second pipe end. The first pipe end has a sealing cone facing toward the second pipe end and a shoulder section. The connecting system includes a first clamping disk surrounding the first pipe end and a second clamping disk surrounding and connected to the second pipe end. The connecting system further includes a multiplicity of screws, detachably connecting the first clamping disk to the second clamping disk. The first clamping disk includes an outer circular disk ring and an inner circular disk ring which is detachably connected to the outer circular disk ring. The inner circular disk ring has multiple separate circular disk ring parts, and an outer diameter of the inner circular disk ring is greater than an outside diameter of the shoulder section provided on the first pipe end.

Claims

1. A connecting system comprising:

a first pipe end and a second pipe end, both of which are provided for creating a detachable connection, wherein the first pipe end comprises a sealing cone which faces the second pipe end and said first pipe end is inserted with the sealing cone in a concentric manner into the second pipe end and comprises on its outside surface a circumferential shoulder portion, wherein the largest outside diameter of the sealing cone is greater than the outside diameter of the remaining first pipe end such that the shoulder portion is produced,

a first clamping disk which surrounds the first pipe end and is arranged on the side of the shoulder portion remote from the sealing cone,

a second clamping disk which surrounds the second pipe end and is connected to the same, and

a plurality of screws which connect the first clamping disk to the second clamping disk so as to be detachable,

wherein the first clamping disk which surrounds the first pipe end includes an inner circular disk ring and an outer circular disk ring wherein the inner circular disk ring is detachably connected to the outer circular disk ring in a concentric manner such that the inner circular disk ring is flush with the outer circular disk ring, wherein the inner circular disk ring includes several separate part circular disk rings, wherein the several separate part circular disk rings include two separate semi-circular disk rings, and wherein an outside diameter of the inner circular disk ring is greater than an outside diameter of the shoulder portion which is provided on the first pipe end.

2. The connecting system as claimed in claim 1,

wherein the screws are distributed uniformly along the circumference of the pipe ends.

3. The connecting system as claimed in claim 1,

wherein the screws include wedge lock washers.

4. The connecting system as claimed in claim 1,

wherein the heads of the screws are arranged on the first circular disk and extend above the inner circular disk ring.

5. The connecting system as claimed in claim 1,

wherein a contact surface between the inner circular disk ring and the outer circular disk ring comprises a conical form.

6. The connecting system as claimed in claim 1,

wherein a contact surface between the inner circular disk ring and the outer circular disk ring comprises a ring-shaped support surface.

7. The connecting system as claimed in claim 1,

wherein a contact surface between the inner circular disk ring and the outer circular disk ring comprises a thread.

8. The connecting system as claimed in claim 1, wherein an outside surface of the second pipe end includes an outside thread and wherein an inside opening of the second clamping disk includes a thread configured to be screwed onto the outside thread of the second pipe.

9. The connecting system as claimed in claim 1, wherein the sealing cone comprises a circumferential groove to insert a sealing material.

10. A connecting system comprising:

a first pipe end and a second pipe end, both of which are provided for creating a detachable connection, wherein the first pipe end comprises a sealing cone which faces the second pipe end and said first pipe end is inserted with the sealing cone in a concentric manner into the second pipe end and comprises on its outside surface a circumferential shoulder portion, wherein the largest outside diameter of the sealing cone is greater than the outside diameter of the remaining first pipe end such that the shoulder portion is produced,

a first clamping disk which surrounds the first pipe end and is arranged on the side of the shoulder portion remote from the sealing cone,

a second clamping disk which surrounds the second pipe end and is connected to the same, and

a plurality of expansion screws which connect the first clamping disk to the second clamping disk so as to be detachable,

wherein the first clamping disk which surrounds the first pipe end includes an inner circular disk ring and an outer circular disk ring wherein the inner circular disk ring is detachably connected to the outer circular disk ring, wherein the inner circular disk ring includes several separate part circular disk rings, wherein the several separate part circular disk rings include two separate semi-circular disk rings, and wherein an outside diameter of the inner circular disk ring is greater than an outside diameter of the shoulder portion which is provided on the first pipe end.

11. A connecting system comprising:

a first pipe end and a second pipe end, both of which are provided for creating a detachable connection, wherein the first pipe end comprises a sealing cone which faces the second pipe end and said first pipe end is inserted with the sealing cone in a concentric manner into the second pipe end and comprises on its outside surface a circumferential shoulder portion, wherein the largest outside diameter of the sealing cone is greater than the outside diameter of the remaining first pipe end such that the shoulder portion is produced,

a first clamping disk which surrounds the first pipe end and is arranged on the side of the shoulder portion remote from the sealing cone,

a second clamping disk which surrounds the second pipe end and is connected to the same, and

a plurality of screws which connect the first clamping disk to the second clamping disk so as to be detachable, wherein the screws comprise an inner drive such that the screws are configured to be tightened or loosened with a screwdriver,

wherein the first clamping disk which surrounds the first pipe end includes an inner circular disk ring and an outer circular disk ring wherein the inner circular disk ring is detachably connected to the outer circular disk ring such that the inner circular disk ring is flush with the outer circular disk ring, wherein the inner circular disk ring includes several separate part circular disk rings, wherein the several separate part circular disk rings include two separate semi-circular disk rings, and wherein an outside diameter of the inner circular disk ring is greater than an outside diameter of the shoulder portion which is provided on the first pipe end.
