System for stringing a first elongate element into a second elongate element

摘要

A method for stringing a first elongate element through a second elongate element is provided by placing the first elongate element in a channel and injecting compressed gas into the channel to propel the first elongate element therethrough. The channel has a first open end, and the second elongate element is sealed around the first open end. Compressed gas is injected into the channel towards the second elongate element, propelling the first elongate element through the second elongate element. Also disclosed is a system for performing such a method, including a source of compressed gas and a housing having a channel with a first end and a second open end. The first end is in fluid communication with the source of compressed gas. The channel has a tapered portion adjacent the open end of the channel, and the channel defines a straight longitudinal axis between the first end and the second open end.

1. A system for stringing a first elongate element through a hollow tubular member, the system comprising:
a source of compressed gas; a housing having a channel extending therethrough, the channel having a first end in fluid communication with the source of compressed gas and a second open end; the channel having a tapered portion adjacent the open end of the channel in which the cross-sectional area of the channel tapers toward the open end; a first moveable clamp member and a second moveable clamp member, the first and second moveable clamp members configured to hold an end of the hollow tubular member adjacent the second open end of the channel; wherein the channel defines a straight longitudinal axis between the first end and the second open end.
