Multiple Wire Wrap Screen Fabrication Method

摘要

A wire wrap screen manufacturing method for a given screen diameter involves simultaneous winding of parallel wires that begin in circumferentially offset locations on one end of a perforated base pipe that has circumferentially spaced support rods saves fabrication time. Each of the ends of the wires lie in a common plane to allow fitting an end cap for sealing or to just continuously weld at the ends of the wires to seal the assembly to the base pipe. The spot welds to the support rods occur as the wire is wound over such rods. Equal initial circumferential spacing of the start locations for the wires is preferred although asymmetrical spacing is preferred.
