Reverse Vee Wire Wrapped Screen Johnson Type 150 - 1000μm Slot

Rverse Vee Wire Wrapped Johnson Type Screen Filter Pipe Back Wash

Description:

Reverse coil screen,  Filter pipe is also known as "filter pipe" "screen pipe". The most famous is the Johnson Tube. But there are many kinds of filter tubes.
From the material has stainless steel, low carbon steel galvanized, plated other metal and so on.
The water pipe is usually considered to be well pipe. The water supply industry in our country usually adopts cast iron pipes or steel pipes wrapped with wire perforation and sieve pipe. Such water pipes are easy to be corroded and blocked by chemistry, electrochemistry and action in groundwater, which reduces the intake water efficiency and reduces the life of the well. Especially when the local water is corrosive, severe damage will make a large number of gravel into the well, causing silting well and burning the pump, backrolling the screen material, so that the well is scrapped. In order to solve this problem, reverse coil screen use, domestic and foreign research stainless steel filter, glass fiber reinforced plastic filter, asbestos or cement pipe wire filter, paste hone filter and so on, but because of the high cost of raw materials, complex processing technology, low water capacity, and bulky structure and other factors make its application scope is limited, reverse coil screen manufacturers, and not widely popularized.
Screen specifications often depend on different, not business, different standards. At present, the specifications of screen mesh have not been unified in China. Due to the complexity of particle shape, there are usually several representation methods, such as screening size, settling size, equivalent volume size and equivalent surface size. So the size of the screen can be set according to the size of its own particle material.

The characteristics of:

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 in the world 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 the commonly used welding technology in China, 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.
