Abstract:
1. A method for making a screen on a pipe, comprising: locating a first wire about a plurality of rods longitudinally disposed on an outer surface of a pipe; engaging each rod of the plurality of rods with a corresponding contact member, wherein each contact member is moveable away from a longitudinal axis of the pipe, and wherein each contact member is connected to a mounting ring outwardly disposed from the pipe; welding the first wire to the plurality of rods; moving the contact members radially outward in a linear direction away from the plurality of rods to form a gap therebetween; and moving the mounting ring longitudinally along the pipe such that the contact members traverse an obstruction extending from the outer surface of the pipe, wherein an outer diameter of the obstruction is greater than an outer diameter of the first wire wrapped about the plurality of rods.
