FIELD: machine building.SUBSTANCE: group of inventions relates to connecting units. A connecting unit to form a connection in the secondary built-in system between the first section of a secondary pipe and the second section of a secondary pipe and to place a primary connection in the system. The unit consists of the first connecting element and the second connecting element. The said elements comprise a longitudinal axis between the first end and the second end, the first end of each connecting element includes the first tubular section with the first inner diameter intended to form a sliding fit with the said first section of the secondary pipe, and the first sealing unit for sealing at the usage with the first section of the secondary pipe, the second end diameter is greater than the first inner diameter. The end surface is set in the plane in essence reclining in relation to or shifted from the longitudinal axis of the connecting element, and the second end additionally comprises a matching zone. A version of the connecting unit is described.EFFECT: invention improves the connection reliability.33 cl, 54 dwg |
