Huadong Industrial Co,Ltd

We are offering 8 inch continuous slot well screen.continuous-slot well screenapplicationthe continuous-slot screen, widely used throughout the world for water, oil, and gas wells, is the dominant screen type used in the water well industry. Production methods1.winding cold-rolled wire, approximately triangular in cross section, around a circular array of the longitudinal rods. 2.the wire is attached to the rods by welding, producing rigid one-piece units having high strength characteristics at minimum weights.3.slot opening are manufactured by spacing successive turns of the outer wire to produce the desired slot size. All slots should be clean and free of burns and cuttings.4.process: for carbon steel screen, we can paint black lacquer or silver lacquer, or galvanized, stainless steel screen will be polished.5.package: inner bubble bag and outer woven bag. Wooden box can be employed if needed.

We are offering galvanized rod based well screen. rod based well screens are the work-horse of the well screen industry and have been used for over 60 years for sand control. Wire wrap screens can be used in both gravel pack and stand alone screen applications. features: consistent weld integrity at every point of welding. tight slot control for consistent flow rates. stringent quality control measures ensure a quality product. weld rings or threaded fittings as per customer requirements. multiple wire profile options to suit applications and specification.

V-wire 1mm slot screens are manufactured using our unique computerized machinery, developed in-house, and in which a continuous length of profile wire of a triangular section is fusion welded onto support rods.This 'v' shaped profile wire is wound around the support rods over the full length of the screen thus creating a continuous slot opening.Metal well screens offer many advantages including:a continuous slot opening which significantly increases the available open area, thus providing greater access to the water bearing zone (the aquifer) a "v" shaped profile wire which avoids clogging and ensures an uninterrupted flow. A uniform and efficient well development due to the continuous slot opening. Technical details slot (mm)standards : 0, 25 0, 50 0, 75 1, 00 1, 50 2, 00 3, 00.Customized slots materials of construction:aisi 304 & 316 grade stainless steel, low carbon steel, galvanized steel.Screen lengths (meters)standard lengths : 2, 90 m & 3 m or 5, 80 m & 6 m (for others, please contact us). Note: the technical specification of well screen can be changed according to customers specific requirements.

We are offering pipe based well screens.pipe based well screenspipe based screen combines stainless steel or carbon steel casing with continuous slot well screen for additional strength in deep well applications. The pipe strength allows smaller wrap wires to be used, allowing for greater open area.Features:higher collapse resistance.Higher load strength.Easily controlled open area for regulated flow rates.Threaded fittings in any specifications required.Base pipes can be manufactured using stainless steel grades or api 5ct carbon steel casing.1. Pipe base well screen 2. Material: 201 304 304l 316 316l q235 3. Another name: pipe base screen 4. Screen jacket: johnson type screen 5. Base pipe: perforated pipe 6. Connection type: stc, ltc, btc threaded couplings7. Bubble bag, wooden pieces wrapped the johnson screens screen jacket base pipe multilayer well screen pipes are used for oil and water exploiting. characteristics: pipe base screen consists of two screens or multilayer screens perforated pipe inside , with perforations wrapped by the outside johnson type screenthe screen jacket and base pipe are welded together with a length of coupling. the base pipe can be made of seamless pipe or welded pipe, and more often, casing pipes. id of johnson type screen equals od of the perforated pipe.

We are offering stainless steel johnson water well screen.the welded stainless steel johnson water well screen 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 screens full length.What does these advantages mean to you? 1.protection for your pumpthe 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 costseven 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 lifethe 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 wellpart 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.
