The pipe based screen is produced by wrapping a high precision wedge wire screen around an API compliant base pipe. The built-in pipe provides extra support to the outer wrap screen layer, which makes the pipe based screen suitable for severe environments such as high pressure, high temperatures or deviated wells.
This process is carried out to divert water away from the soil where the building foundation will be placed, keeping the area dry and solid. Hengyuan's water well screens are widely used on drainage pipes in construction sites to filter out sand from the water, and improve the water removal efficiency.
Screen slot design is a crucial aspect in the efficiency of production wells. Precise slot control starts with precise slot forming. Because of that, Hengyuan wedge wire screen is constructed by helically winding a continuous triangular shaped wire around a series of vertical support rods, ensuring the final screen slot will meets our strict quality standards.
Heat pumps are properly known as geothermal air conditioners. They transfer heat into or out of the ground to cool or heat your home by using a water well as a heat sink. The water well screen is a key component of geothermal wells, keeping sand out of the water pumping system.

The prepacked screen has two wrap layers of wedge wire, with resin coated sands, ceramic, or resin pellets sandwiched between the layers. This dual screen design is effectively used for sand control as it will reduce the sand content found in the liquid that is passing through the screen.
The pipe based screen is one of the most popular products in various oil projects, as they combine hydraulic efficiency of a vee wire screen with the strength of a pipe. The outer screen layer allows oil to flow in, while still keeping sand and other abrasives out, reducing the chances for abrasion caused by sand and saving maintenance costs.
Oil related businesses in China have a long history of different oil projects. As a prominent casing pipe supplier, Hengyuan is capable of handling different oil project needs for borehole casings. We purchase quality casing pipes at the lowest possible price, and ship them to you as fast as possible.
Supported by a rebar on the outside, the cylindrical extruder screen is specifically designed for polymer and fiber filtration in extruder barrels. Excellent rigidity and strength are key for the cylinder screen to be used in vane cylinders, where rotary vanes generate a great shearing force.
Hengyuan has the expertise needed to customize screen cylinders for specific makes and models of self-cleaning filters. The operation of self-cleaning filters is based on a simple concept: when pressure in the screen filter is below the permitted level, the cylinder screen allows fluid to pass while filtering out impurities.
In wastewater treatment tanks, wastewater is treated with ion exchange resins and thus, turned back into useable water. Resins are expensive and should not be discharged with the treated water. Due to that, resin traps are manufactured and put into use.
The wedge wire filter cartridge is made of vee-wire wrapped in a circular manner around stainless steel support rods. The smooth profile wire surface is where the filtration actually takes place. Continuous slots widen inwardly, giving the filter cartridge its non-clogging ability.
A support grid is a flat screen typically used to support and retain expensive filter media in a treatment vessel, or along a solid/liquid separation system or process.
Welded for strength and longevity, the support grid is rigid enough to resist buckling or collapsing due to hydrocracking or desulphurization.
Hengyuan manufactures wedge wire screens used in percolation filters. A high open area and rigid welding construction give the vee-wire screen the ability to withstand vibration and pull. Little to no maintenance is needed, saving costs and contributes to the long service life of the percolation filter.
Screen baskets are commonly used on both inlet and outlets of treatment vessels for flow distribution, collection and material retention. Request a quote today with your screen basket requirements, and one of our engineers will contact you in response.

The desliming screen is one of the most commonly used filtration components in wastewater treatment and other solid/liquid separation systems. Typically made from wedge wire and support rods, the flat panel wire screen provides a simple and effective way to remove slime from valuable process fluid.
These cylindrical screens are welded in one continuous length at each wedge wire and support juncture. The high structural integrity allows slots to be placed closer together for an increased screening efficiency. Advanced welding technology also results in a smooth weld surface with no sharp edges, corners or burrs.
Hengyuan's large-diameter cylindrical screen is specifically designed for heavy duty, solid/liquid separation tasks. Made by welding wedge wire in a circumferential helix pattern onto a series of support rods, the cylindrical screen provides high strength and evenly distributed slots.
Candle filters have been around for decades and are generally used for liquid purification. At the core of any candle filter, is the filter cartridge, which serves as a barrier to separate harmful contaminates from clean water. Often, a thin layer of diatomaceous earth will be applied to the surface cartridge, and act as the filtration medium.

Made by welding vee-wire in a circular manner to the support rods, each sieve bend is ideal for rigorous sizing applications. For heavy duty water removal and classification tasks, we use thicker wedge wire and support rods to produce a rigid sieve bend screen.
Different production stages call for different screen plates, which is why we use diverse wire profiles to make the plates, including vee-wire and o-shaped wire. Depending on the size range to be sorted, we can customize the screen plate to fit your production requirements.
We have the needed expertise to produce different sieve bend screens according to the size, arc degree, and slot openings customers require. A high open area allows for more water to seep through the slot openings, while still retaining the cassava fibers on the surface.

Filter screens are essential to aquaculture systems, as they serve to remove the majority of particles in the initial cleaning steps. Hengyuan supplies a variety of sieve bends, all of which are capable of filtering out particles of 0.05 microns and larger to ensure the highest screening efficiency, all while preventing clogging.

Each of these wedge wire filter screens is welded for strength and screening efficiency, and are available with uniformly distributed slots. Options for the screen materials include stainless steel in grades 321, 304, 304L, 316, 316L, or galvanized carbon steel.
