A connection piece for pipe connections, which connection piece comprises a tubular envelope having a first end and a second end, which connection piece comprises a channel between the first end and the second end, the channel being delimited by an inner surface of the envelope of the connection piece, which connection piece comprises a first connection area extending to a distance from the first end and a second connection area extending from the second end to a distance, which connection piece has been configured to be bent in a first plane, such as vertical plane, by an angle alpha (α) which is 0-20 degrees, and/or in a second plane, such as horizontal plane, by an angle beta (β) which is 0-20 degrees. The invention also relates to a conveying pipe arrangement and to a method.

The conveying pipe arrangement according to claim 21, wherein, at a connection between the first conveying pipe section and/or the second conveying pipe section and the connection piece, a connection sleeve part has been arranged to be used, which connection sleeve part has been arranged to enclose a connection area of the first conveying pipe section and/or the second conveying pipe section and the connection piece disposed within the connection sleeve part.
A method for forming a conveying pipe arrangement of a pneumatic material conveying system, which conveying pipe arrangement comprises at least one first conveying pipe section and one second conveying pipe section, a connection sleeve, and optionally a connection piece between the first conveying pipe section and the second conveying pipe section, in which method the first conveying pipe section is connected to the second pipe section directly or via the connection piece by inserting the ends of the pipe parts to be connected to each other into the connection sleeve and by forming a thermoplastic connection with the pipe part and the connection sleeve, and/or optionally with the connection piece and the connection sleeve.
The method according to claim 26, wherein in the conveying pipe arrangement, the direction of the channel of the conveying pipe section is changed by bending the connection piece arranged between the first conveying pipe section and the second conveying pipe section in a first plane, such as vertical plane, by an angle alpha (α) and/or in a second plane, such as horizontal plane, by an angle beta (β).
The method according to claim 27, wherein the angle alpha (α) is 0-20 degrees.
