HARPSCREEN’S WELDED WEDGE WIRE SCREENS
Harpscreen are pioneers in the development of wedge wire screens. In recent years a demand has grown for wedge wire assembled by welding. We have met this demand with the very latest in TIG welding technology.
Using specially developed machinery and advanced automatic welding, our welded type screens offer a wide range of apertures with clear and unobstructed open area.
This latest development uses 6.35 mm diameter cross rods or up to 25 x 6 mm flat bars welded directly to the profile wires. Cross rod pitch can also be varied to suit the application.
Reinforcements can be added if needed. This provides the strongest and also most cost effective welded wedge wire screens on the market. Usual materials are stainless steels in AISI grades 304 and 316, however metals are also available.
As well as the usual flat or curved screens, welded wedge wire is made into tubes and also cylinders, with radial or straight slots. The screen surface can be either on the inside or the outside of the cylinder, to give flow in-to-out, or out-to-in. Usually made in stainless steel grade AISI 304, however other grades are also available.
Welded wedge wire is used in a wide variety of general industry applications – please call for more details.
