Sell 304 stainless steel tube(manufacturer)

Description

The welded **4�stainless steel tube�is made up of supporting rods and wire screening strips. V wire Johnson well screen, unlike every other type of screens. Johnson well screen uses a unique design consisting of a series of steel support rods around which a continuous length of wire is wrapped. Each intersection of wire and rod is automatically welded making a very strong cage-like cylinder with one continuous slot spiraling along Johnson well screen�s full length.

What does these advantages mean to You?

1.�������Protection For Your Pump

The slots of Johnson well screens are very narrow and precisely sized to keep out even fine sand grains which could otherwise destroy your pump through abrasion.

Lower Pumping Costs

Even with narrow slots, the total open area for the water to enter is far higher than any other kind of screen design. More water with lower pumping costs.

2.�������Longer Well Life

The slots widen inward so sand grains don't wedge and plug. The Johnson well screen is stainless steel for maximum corrosion resistance. The high open area of a Johnson well screen lets the water enter slowly to avoid the problems which arise when water is pumped at high velocity.

3.�������A More Efficient Well

Part of well construction involves a process called "well development" in which finer sand grains are pumped into the well and removed. By the end of the process, only the larger sand and gravel particles are left next to the well screen. the water then passes freely around these coarse particles and enters the well.

Remember that every drop of water from your well must first pass through the well screen. A Johnson well screen is stronger, more plug-resistant, longer lasting, and more efficient than any other screen design available anywhere. That means more water for you, for a longer time, at less cost.
