SS 316 Slot 40 Johnson Type Wedge Wire Backwash Filter Tube for filter cartridge is composed of V-shaped profile wires and longitudinal support rods, forming a tube body with fixed value grooves. The custom grooves are CNC machined to ensure uniform gaps, with each intersection fusion welded for solid structure and excellent mechanical properties.

The opening of the tank is V-shaped with small internal opening and large external opening. This design prevents impurities from passing through from inside to outside while allowing backwashing from outside to inside, avoiding clogging and extending service life.

Reverse V Slot Wedge Wire Drum Screen is widely used in oil, gas and water wells for sand prevention and its application in chemical industry, environmental protection and other industries.

It is the most widely used filter screen in all kinds of oil, water resources recycling and resin collection. The world's most advanced full wound welding process is adopted by the Johnson Vee-shaped wire winding screen.

The special stainless steel trapezoid (wedge-shaped) wire winding is welded on a group of longitudinal support rods arranged in a round round arrangement, thus ensuring its strength and service life.

Due to the adoption of full program welding, not only the strict integrity of the product is ensured, but also the ideal gap size is formed. Compared with commonly used welding technology, the full welded wedged wire winding screen tube, filter pipe, water cap, water distributor, resin trap and sieve plate have the characteristics of smooth tube surface, no production edge angle, no burr, uniform gap and no grease leakage.
