Moulding device and method of generating a cast of an inner surface of a tubular member

A moulding device (90;

• 92;
• 95;
• 98;
• 100;
• 110) suitable for use in a tubular member (17),
• comprising:
• a first closing part (7, 8) with a first opening (7a);
• and
• said first closing part (7;
• 8) is arranged to be placed at least partly inside said tubular member (17) and to seal against the inside of the tubular member (17) in its position at least partly inside said tubular member (17) such as to delimit a chamber (10):
• wherein
• said first closing part (7, 8) defines a cavity (9) comprising said first opening (7a) and a second opening (7b), where said first and second openings (7a, 7b) are placed on opposite sides of the first closing part (7, 8);
• wherein the first closing part (7, 8) comprises a cup part (7) having said first opening, (7a) and a lid part (8) having said second opening (7b), where said lid part (8) is arranged to be connected to the cup part (7), so that the cup part (7) and the lid part (8) together form said cavity (9);
• and
• wherein said cavity (9) is in communication with said chamber (10) via the opening (7b) in the lid part (8) such that a cast is formed by introducing moulding material into the chamber (10) including the cavity (9).
