Place of Origin:
V-wire welding Screen developed by Johnson Screen to solve the problem of solid-liquid separation has been widely used in oil, gas, water well sand control, refining, food filtration, nuclear power and other fields worldwide, especially in the nuclear power industry and petrochemical hydrogenation reforming unit. Because of the excellent performance of the product, so that it is useful in many fields, Johnson mesh is welded by the surface wire around a circular arrangement of a group of longitudinal support wire welding. The welding process is divided into: argon arc spot welding and intermediate frequency resistance welding.
The surface wire is connected with the support wire by welding, and the strict continuous integrity makes the Johnson net have the excellent performance of small weight and can withstand high pressure, and the gap error can reach ±5 microns. The production of Johnson net can choose different materials according to the needs of different working environments. The width of the surface wire is generally: 0.45mm, 0.76mm, 1mm, 1.2mm, 1.2mm, 3mm and other specifications, its material mainly includes: stainless steel SUS304, 316L, 321, Monel copper-nickel alloy, duplex steel, 904L, nickel-based alloy, titanium alloy and other special metal materials.
The gap opening data of Johnson's net is formed by spacing continuous wire welding to form the ideal gap size. The individual slot space of Johnson net can be different in the production process. In fact, a single section of Johnson's net can also be made to create gaps of different precision when working environment conditions require changes. This is conducive to the use of the process to reach the limit of the application.
The slit size is accurate and the filtering precision is high.It has the advantages of strong structure, high ventilation efficiency, good heat dissipation, high temperature resistance, corrosion resistance, good mechanical properties, long service life, safe and reliable.
It has high strength, stiffness and bearing capacity, and can be used as a rigid screening filter for various shapes.This product is made of advanced fusion welding technology. The screen has the highest screening efficiency, the strongest anti-tensile capacity, the minimum maintenance requirement, and the longest service life.
We can also frame the arc-shape screen with polyurethane to strengthen its structure and make it have longer service time

|SIZES OF THE WIRE AND ROD|
Special specification can be made according to your need.
Not easy to jam
the special V shaped wire, make the hole of screen outside face is smaller than inside, so the hole is not easy to jam.
The CNC machine tools strictly control the gap between the wire, so that the gap is even.
Strong corrosion resistance
Stainless steel have the high corrosion resistance
Easy to backwash, clean without dead Angle.
Filter from inside to outside , and the outside slot is bigger than inside slot, so it is easy to bakc flush.
Built-in scraper, brush, suction first class cleaning device.
