Abstract

Herein a tubular element (2) is disclosed. The tubular element comprises a first tubular portion (4) comprising a first metal or alloy and a second tubular portion (6) comprising a second metal or alloy. At least a portion of an interface (9) between the first and second tubular portions (4, 6) extends within a fixed diameter range along a longitudinal direction (L) of the tubular element. The second tubular portion (6) comprises a first end portion (8) arranged around the first tubular portion (4). The second tubular portion (6) comprises a sealing surface (10) extending circumferentially around the second tubular portion (6) at the first end portion (8).

Description

technical field [0001] The present disclosure relates to a tubular element. The present disclosure also relates to tubular assemblies. The present disclosure also relates to an assembly comprising a wall member and a tubular element. Background technique [0002] Tubular elements are used in countless different applications. Joining two metal pipes made of different materials can be difficult. Also, arranging the tube to extend through the wall may cause specific problems for the tube. [0003] GB1258141 discloses a method for joining two pipes of different alloys which are difficult to join by welding. According to the method, a connecting pipe is produced having a first end of a first alloy and a second end of a second alloy, wherein the first alloy is compatible with the alloy of one of the two pipes, the The second alloy is compatible with the alloy of the other of the two tubes. Between the end portions there is an intermediate portion in which the first alloy for...
