A well screen is a filter device used as the suction portion of a well constructed in a loose or semi-consolidated aquifer. The screen allows water to enter the well from the saturated aquifer, prevents sediment from entering the well, and acts structurally as a support for the aquifer material. When considering well efficiency and the logarithmic cost to the well owner, the importance of having the right screen cannot be overemphasized.
The sieve is resistant to corrosion because it comes into contact with water. In addition, it has high strength and can keep the surrounding structure intact. The openings of the sieve can be small enough to block the large amount of formation around them. The flow of water through the screen will be uniform.
Well screens are recommended for all environmental drilling operations. It helps extend the life of the well and keeps the flow of water unrestricted. Sand and fine powder sand, these fine particles can be filtered out before there is water. Well screens help remove most of this fine material from well water.
Well screens are made from a variety of materials, ranging from rough-hewed hand designs to machine built high-efficiency and long-life models. The value of the screen depends on how much it contributes to the success of the well.
Standard:
- Large open Spaces
- Do not block the slot
- 3.corrosion resistance
- Sufficient column and collapse strength
Functions:
- Easy to develop
- Minimal scaling tendency
- Low head loss through the screen
- Control sand pumping of all types of aquifers
Slot size selection is a critical step to ensure maximum well performance. The screen is usually designed to block 50% of the stratum, and the entry speed for the screen should not exceed 1/10 or 0.1 ft per second. The velocity is calculated by dividing the well production in GPM by the screen open area in square inches.
The gap size of the screen is based on dimensional analysis of the formation sample. After analyzing the composition size of grain in the sample, grain size distribution curve
I can draw it. Several methods can be used to obtain the allocation of information about grain size. The most widely used method is to pass the material through a stacked set of brass or stainless steel sieves. During the screening process, each sieve removes a certain percentage of the whole sample; The best materials are collected in the chassis. Screening analysis not only provides the basis for determining slot sizes, but also other factors that influence screening well design.
Galvanized Steel Fiber, an alternate concrete reinforcing material are high tensile galvanized steel wires with hooked ends, glued together by the water-soluble adhesive for compactness and uniform dispersion in concrete, to increase the concrete properties by 3-4 times.
Compared with the normal cold drawn steel fiber,in addition to all the advantage of normal steel fiber(such as excellent tensile strength, bending and shearing strength, high tenacity, resistance against the cracking, impact and fatigue ), this fiber still has a better corrosion resistance when the steel fiber exposure to the air, as there is a zinc thickness on the surface of this fiber.
The concrete with GuangYa steel fiber can be widely used in industrial floor,transportation constructions(roads, bridges, tunnels, airport runways), the concrete prefabricated unit, etc…
Advantage to use the China steel fiber in concrete:
High impact resistance.
Remarkably increased flexural strength.
Improved structural ductility.
Exceptional control over cracking.
Increased durability by providing crack control.
Glued Steel Fiber, an alternate concrete reinforcing material are high tensile steel wires with hooked ends, glued together by the water-soluble adhesive for compactness and uniform dispersion in concrete, to increase the concrete properties by 3-4 times.
steel fiber reinforced concrete supplier improve the mechanical properties concrete and materials such as ductility,

Compared with the GuangYa loose steel fiber the operation and advantages of the glued steel fiber:
- Add the steel fiber directly into the belt, the whole row of steel fiber as a whole, evenly dispersed in the concrete corner
- The water-soluble glue begins to dissolve in a row of steel fibers in the premise of the dispersion, it is again dispersed in every corner of the mono filament fiber, showing the perspective in the concrete of the fiber mesh, which plays an integral strengthening.
- Compared with mono-filament fibers, China bonded steel fiberswill not be bundled to ensure that the fibers in concrete do not coalesce and distribute evenly.
Glued steel fibers are loose hook-end fibers that are bonded together in a row. The great difference between loose fiber and glued fiber is that the former is easy to clog and the latter is easy to disperse evenly.

Razor wire, also known as razor wire, is a new type of protective product developed with strong protection and isolation capabilities.
Stainless steel barbed wire is different according to the different application areas containing nickel. The effect of using 304 stainless steel in a dry indoor environment is quite good. However, if you want to maintain its appearance outdoors in the countryside and cities, you need to wash it frequently. In heavily polluted industrial areas and coastal areas, the surface will be very dirty and even rusty. However, to obtain the aesthetic effect in the outdoor environment, nickel-containing stainless steel is required. Therefore, 304 stainless steel is widely used in curtain walls, side walls, roofs and other construction purposes. However, 316 stainless steel is best used in severely corrosive industries or marine atmospheres.
Razor nets have been widely used in military powerhouses, prisons, government agencies, banks, and living quarters, private houses, villas, doors and windows, highways, railway guardrails, and borders to protect security in various countries around the world.

Copper Mould Tube & Plate
We specially in supplying Copper Mould Tube, Crystallizing equipment of continuous casters, Mould cooling jacket, Repair of Metallurgical Copper Mould Tube, etc.
Equipments & Spare parts for Continuous Casting Machine.
- Copper mould tube( square, rectangle and round )
- Crystallizing equipment of continuous casters
- Mould cooling jacket.
- repair of copper tube moulds
The copper alloys chosen for the moulds must maintain their physical properties at the operating temperatures of the continuous casting process.
The temperature gradation from the inner wall of the mould to the outside face of the mould can cause serious distortion problems, and Metallurgical Copper Mould Tube is imperative that the correct alloy is chosen for the various operating conditions.
Square Copper mould tube STANDARD MATERIALS
Phosphorus de-oxidised copper
This alloy has been proven to be excellent for the manufacture of moulds in the continuous casting of billets. The main composition of this alloy are Cu +Ag 99.90min, P0.0015 / 0.040.
Copper -Silver alloy
The addition of a small amount of silver, whilst not increasing the melting point of copper, does increase the recrystallisation temperature by almost 100℃, and also helps to give better thermal conductivity at the operating temperatures.
This alloy is normally used in moulds for the continuous casting of blooms and slabs .In this case, the moulds are much thicker than in the billet moulds, and the moulds temperature can be higher. The main composition of this alloy are Cu+Ag99.90 min. Ag 0.08 / 0.12 O 0.004 / 0.012.
The continuous casting of molten steel into billets, blooms and slab products, has been highly refined over the years into an extremely sophisticated system. The continuous casting process is expected to produce metallurgically sound products at the lower possible cost, and this is being achieved in many steelworks throughout the world.
Copper moulds have played an important role in the development of the continuous casting process. Their funcition is to receive the molten steel and to allow rapid heat transfer from the steel to the cooling water to enable quick solidification.
The mould must exhibit excellent thermal conductivity, be resistant for thermal erosion ,and be resistant to distortion from thermal stress. So far only copper and a few copper alloys meet the above conditions, both economically and technically.
Mould cooling jacket supplier SOLIDIFICATION
The rate of solidification in the continuous casting process dictates the speed of production. The molten steel, which is in contact with the inner faces of the copper mould, starts to sllidify as rapidly as the heat is extracted, forming a shell. The shell increases in thickness as more heat is extracted, and eventually total solidfication is achieved. the process is similar to the solidification of ingots in ingot moulds. In continuous casting, the whole process is speeded up, with the aim to produce and homogeneous shell growth. Consequently, the mould is an important part of the continuous casting process, and the manufactured quality of the mould plays and important role in their length of life.
INNER SURFACE COATINGS
Over the years, Metallurgists and Engineers have been working together to develop better continuous casting moulds. The steel companies require a more economical mould which will give a longer service life. Surface coating of the inner walls of the mould has given the best results to date. Coatings available are Chromium and Nickel plating. Also, a combination of the two give good results on slab casting.
