Haixing Wedge Wire Company

We are a manufacturer of continuous slot wedgewire well screen in china. The wedgewire products are manufactured by rolling a v-shape wire around an internal framework of longitudinal bars. The external v-shape wire can have either a sharp end, in what is known as vee-wire sharp, or it can have a round end in what is known as a vee-wire wear. Depending on the type of wire used and the slot opening, the open area of a wedgewire screen can vary between 10% and 70% of the total area (see graph). The average opening area of a water well screen varies from 35% to 45% compared with 5% to 15% on average of a other screens (e.g. Perforated or bridge screen). In the case of support grids, the filtering area can be up to a 70% of total area, depending on the material used and the slot.the continuos slot water screen has several advantages compared to other screens such as bridge slot screen or perforated screen. A larger opening (filtering) area of a wedgewire screen leads to superior performance of a water well compared against the installation of other types of screens. Moreover a wedgewire filter for water well are self-cleaning (go-no go), thus, prevents losses due to friction as well as losses associated with pumping sand. Also, a continuous slot wedgewire water well screen eliminate the problems associated with fine sands, thus, increasing the life of the pumping equipment. nb 1.5", 2", 3", 4", 6", 8", 10", 12", 14", 16" slot (mm) 0.15, 0.25, 0.50, 0.75, 1.00, 1.50, 2.00, 3.00 lengths 6 mts. & 3 mts. grades different grades suitable for tube well depths up to 300 ft., 600 ft., 900 ft. And 1500 ft. material low carbon galvanized steel ( lcg ) and stainless steel ( ss-304 ) end connection plain beveled ends for butt welding or threaded. please tell us your demand and then we design , manufacture for you.

Our water well screens are manufactured with v-shaped profile wire which is spirally wound around a cage of longitudinal support rods. Each intersecting point of these wire is fusion welded. The pitch of winding gives different spacing between two adjacent turns of wire.this spacing gives passage for water to enter.the entire process is completed on fully computerized machines.we offer water well screen as the following: 1) slot size (mm): 0.10, 0.15, 0.2, 0.25, 0.30-6mm 2) open area: up to 37% 3) material: low carbon steel, low carbon galvanized steel (lcg) steel treated with plastic spraying, stainless steel (304) 4) lengths up to 6 meters 5) diameter: 1.5", 2", 3", 4", 6", 8", 10", 12", 14", 16", 18" 6) end connection: plain beveled ends for butt welding or threaded.

Wedge wire is an effective method of filtering because of the non-clogging capabilities due to the wedge shape of wire.wedge wire is produced in a range of sizes, such as head width and profile depth with the latter having various side angles to suit a wide range of applications.the wedge wire is continually wound around a set of support rods which are either shaped or round.the wire rod configuration can be designed to suit your particular needs.we have heavy wedge wire profiles in either 304 or 316 grade stainless steel for applications involving coal or iron ore processing or much lighter profiles which give more open area for filtering fine solids from liquids.whatever your situation calls for , we can provide you with a wedge wire screen designed to your own specifications manufactured from the grade 304 stianless or grade 316 stainless steel or others ect. welded wedge wire screens provide a unique combination of the most important features required for maximum screening efficiency.the product is custom designed to suit the specific requirements of the customer and to enable a relatively low cost and high performance solution for the screening application. The high open area of the wedge wire screen provides excellent capacity. Wedge wire screen offers continuous slot openings that widen inwardly so that particles tend to pass through the screen.

Our johnson screens are known for great strength, long service life and a very high level of adaptability for high-efficiency fluid-solid separation.Our welded wire screens use a sur-face wire which is v-shaped in profile, creating slots which enlarge inwardly. This means particles make only two-point contact in the slots and will not become lodged. Other screen types using round perforations or square openings plug easily leading to decreased efficiency and eventual screen failure.The benefits of our screens are:Higher capacity, Reduced cost, since they have excep-tionally long wear life, Effective flow area is maximized resulting in lower pressure drop, Reduced maintenance requirements, Greater resistance to corrosive con-ditions and high temperatures and pressures, Greater resistance to stresses of installation and cleaning, Minimum risk of loss of media like catalyst or resin , Easier accommodation of special site conditions.We look forward to talking with you about the special strength, abrasion, corrosion resistance and other unique requirements of your application. We can design and build the perfect screen to meet those needs.

We are a manufacturer of wire wrapped well screen in china.our wire wrapped well screen designed for effective downhole sand control with minimum pressure drop. It provides maximum inlet area and has more open area per foot of screen length (at any gauge opening and diameter) than any other all welded screen design. The wire-wrapped screen high collapse and tensile strength coupled with a competitive cost structure make it a superior alternative to slotted casing. It is versatile and adapts to many types of applications. The wire wrapped screens is custom built using different combinations of support rods and v-shaped profile wire to meet specific well conditions.please tell us your demand and then we design , manufacture for you.

We are a manufacturer of well point screen in china.the well point screen for dewatering is an incorporate.these incorporate a self jetting head with a non-return ball valve, a stainless steel slotted filter screen, a g.i inner drain pipe and a top coupling which threads to standard 1 ½" (40 mm) riser pipe. The serations on the jet head render penetration, even through hard grounds, easy. Specially designed slots of stainless steel screen, allows maximum water flow with minimum pressure drop and prevents passage of even fine material. The screen eliminates clogging due to corrosion or deterioration due to chemical action.

We are a manufacturer of pipe base stainless steel screen in china.the base pipe, casing or tubing, is selected to api specifications by size, grade and weight for each of your required applications.our slip-on type of pipe base screen is manufactured from two components: the base pipe and the slip-on screen.the base pipe will be perforated with a series of holes drilled to a pre-determined quantity and pattern, to carefully balance flow-capacity at each end for both down-hole handling.the holes are then debarred and the joint cleaned, inspected and treated to give the base pipe a long shelf life.our slip-on screens are manufactured to very exact diameter, length gauge and strength tolerances. This is done by selecting the required profile wire and support rod, which determine the flow-capacity and strength of the slip-on screen. For each gauge opening in the screen we select a slightly greater than that of the perforated base pipe. This will give the pipe base screen optimum flow-capacity at minimum pressure drop across the screen.please tell us your demand and then we design.
