The good quality Johnson screen filter screen tube is manufactured by a v or wedge shaped wire around an internal array of longitudinal support rods.Each intersection point of these wires is fusion welded. The v or wedge shaped profile wire wraps around the support rods over the full length of the screen creating a continuous slot opening,hence the screen allows water (oil) to enter your well freely in ample quantities,while at the same time keeps the majority of sand and gravel out of the well. And the good quality Johnson screen filter screen tube is popularly used in making of water well screen. Stainless steel gravel pack screen pipe is made up of supporting rods and wire screening strips. The supporting rod can be round wire, triangular wire or trapezoid wire. The screening filter is made of triangular wire (V-shaped wire).
The good quality Johnson screen filter screen tube are widely used in oil, gas, water well sand control and applications in chemical and environmental protection industries. It is the most widely used filter screen used in filter materials such as various oils, water resources recycling and resin collection.
The Johnson screen filter screen tube adopts the most advanced full-wound welding production process in the world, and special stainless steel trapezoidal (wedge) wire windings are welded on a set of longitudinal support rods arranged in a circle to ensure its strength and the service life.
Thanks to the full-program welding, not only the strict continuous integrity of the product is ensured, but also the ideal gap size. Compared with the welding process commonly used in China, the all-welded wedge-shaped wire-wound wire screen, water filter pipe , water cap, water distributor, resin trap and sieve plate have smooth pipe surface and no production edge , no burr, uniform gap and no leakage of grease.
