Abstract
An assembly for forming a mechanical interface for fastening tubular components includes a tubular pipe having at least one end with an external surface provided with groove structure. A tubular attachment is provided with a first engagement structure configured to be aligned with the groove structure on the tubular pipe. The tubular attachment is axially force fit on the outer end of the tubular pipe, and radially fastened thereto in response to at least one tool applied to the external surface of the tubular attachment. Also disclosed is a method for forming the mechanical interface between the tubular pipe and the tubular attachment.
Claims20
An assembly defining a mechanical interface for fastening tubular components, the assembly comprising:
- an elongated tubular pipe having at least one end with an external surface provided with groove structure;
- and
- a tubular attachment provided with first engagement structure configured to be aligned with the groove structure on the tubular pipe,
- wherein the tubular attachment is axially force fit on the outer end of the tubular pipe, and radially fastened thereto in response to at least one tool applied to the external surface of the tubular attachment.
A method for forming a mechanical interface between an outer end of a tubular pipe and a tubular attachment, the method comprising the steps of:
- a) providing an external surface at the outer end of the tubular pipe with groove structure;
- b) providing the tubular attachment with first engagement structure configured to be aligned with the groove structure on the tubular pipe;
- c) axially pressing the tubular attachment onto the outer end of the tubular pipe over the groove structure;
- and
- d) radially fastening the tubular attachment to the outer end of the tubular pipe by using a tool for applying at least one of radial force and welding to the tubular attachment outside and out of contact with the external surface of the tubular pipe.
