Scale traps baskets

Scale traps baskets

Scale traps baskets are widely used in process fluid, often contains scale or other impurities which can plug the top surface of the media bed.  By using scale traps baskets, contaminants can be spread over a wider area thus increasing the life-time of media bed.  scale traps baskets have exceptional strength they can be cleaned by blasting or wire brushing.

A series of cylindrical wedge wire screens,scale traps baskets arrayed at the top of the upper catalyst bed either to collect metallic contaminates or scales from plugins the top surface of the upper catalyst bed or to increase the total surface area of the upper catalyst bed to extend the bed’s useful life.

The material of scale traps baskets is usually be SS304, SS316L, SS321 etc.

Rotary Vacuum Cane Mud Filter

Rotary Vacuum Cane Mud Filter
Rotary Vacuum Cane Mud Filters are used in various material and drum constructions. These most advanced filtration systems are mainly utilized in sugar industry. As per the construction material of the drum, each filter is provided with stainless steel screens. In order to maintain a complete vacuum seal, the drum is separated by divisional as well as caulking strips.

Rotary Vacuum Cane Mud Filters is divided into number of sections
Through a specially designed automatic rotary valve-aunique feature of filters, each section of the drum is provided with vacuum
To create a higher vacuum, this valve can be adjusted in the washing zone; this results in a drier cake discharge
The filter drum rotates in the slurry bath of the filter tank
To form a continuous cake on the screen surface, the filtrate is withdrawn through the screen. This ensures uniform thickness of the cake
To increase sugar level, the filter cake on the screen is washed with hot water through drip pipes. After this, the cake is discharged by a floating scraper
For flexibility in the operation, the filter is equipped with a variable speed drive
The filter can easily handle slurries of varying and fluctuating characteristics

Rotating Screen

Rotating Screen

Rotating Screens are  developed for removing of stripeded solids. Higher flow capacities can be used due to continuous and self-cleaning effect of the Rotating Screens. Rotating Screens is with low operational costs.

stainless steel wedge wire screens in the manufacturing process ensures non-clogging opening, accurate full length slots, and a high degree of open area.

The rotating screen drum is designed to meet the requirements of each application giving the optimum open area.

Rotating screen is supported on a fabricated mild steel coated frame
Alternatively, the support frame can be provided in a galvanized mild steel or stainless steel.
All parts in contact with sugar juice are designed using stainless steel
The rotating screen is offered in variety of sizes and apertures to cater to the need of different applications
As most screen sizes utilize taper roller bearings in the design, therefore, the drive power requirements are minimal
The positive drive, which uses roller chain, avoids slip which can occur with other friction drives.
External sprays bars of Rotating Screen help in preventing build-up of harmful bacteria and maintaining operating efficiency
To facilitate transportation and on-site installation, rotating screen is supplied fully assembled on the support frame

Typical separation duties include:

Cush cush straining
Cane wash water
Fly ash water
Pulp press water
Effluent treatment
Sludge screening

borehole drilling water well screens

 borehole drilling water well screens

borehole drilling water well screens is wire wrapped screen,wedge wire screens, well screens, wire wrapped well screens, v shaped water well screens,continuous slot screens.

wire wrapped screen are manufactured by a v or wedge shaped wire around an internal array of longitudinal support rods. The world advanced all-weld technology is used with each intersecting point of the wire fusion welded,which creates the robust construction and excellent mechanical performance.

The v or wedge shaped profile wire wraps around the support rods over the full length of the screen creating a continuous slot opening, hence the Stainless Steel Vee-Wire Screens allows water(oil) to enter your well freely in ample quantities, while at the same time keeps the majority of sand and gravel out of the well. The slots can be changed according to different strata.

1. The V-shape section plane of water well screens creates the continuous slot, which can avoid blockage and make sure of the unimpeded water. 

2.wire wrapped screen have wider open area, and it can reduce the speed of the water entering to avoid the sand entering the screen under the great pressure, so it can control sand better, which can increase the water yield and prolong service time of the well.

3. wire wrapped screen are all-welded, which makes water well screens more robust and longer life.

4. The longitudinal support rods and the continuous slot make the water well screens have more excellent pressure-resistant performance.

5. Specifications and end connections of water well screens can be fabricated according to customers's requirements.

Specification:

Slot Size (mm): 0.10, 0.15, 0.2,0.25, 0.30-3 or as per customers' requirement.

Material: carbon steel, stainless steel (304, 316L etc.)

Unit length up to 6m.

Diameter from 25mm to 2500mm

Open area up to 60%

wedge profile screens

wedge profile screens 

wedge profile screens is continuous slot wire wound screens,provide the water well industry with the most efficiently designed well screen.

We design produces a continuous opening, providing maximum open area whilst maintaining high structural strength, By using the specially shaped wedge wire, a ‘V’ shaped opening, narrower on the outside than the inside is formed. This ‘V’ opening design minimizes clogging and allows maximum development of water wells.This procedure makes the continuous slot wedge wire screen A SUPERIOR PRODUCT IN ALL WATER WELLS. 

We manufactures a comprehensive range of pipe size screen to suit all the standard API, AWW, BSP, O/D and I/D tube sizes from 51mm (2 inches) I/D to 300 mm. 36 inches O/D.

Materials

Well screens can be manufactured from any weldable alloy. The standard stock screens being from AISI type 304 stainless steel, but 304L, 316 and 316L stainless steels and low carbon galvanized steels are used as dictated by water quality.

Lengths

Well screens are available in continuous lengths up to and including 6 metres. 

Slot Openings

Apertures are available from 0.1mm (.004”) in thousandths of an inch up to 10mm (0.4”).

Pipe based well screens

Pipe based well screens

Pipe based well screens consist of base pipe, all-welded wedge wire screen and supporting rod. The base pipe is perforated or slotted API casing pipe, the base pipe can be stainless steel or carbon steel API 5CT casing. The all-welded wedge wire screens are welded together with base pipe by supporting rod.


Features of pipe based well screens


1. Higher filtering accuracy:all-welded wedge wire screens as screen jacket with vee opening design makes the filtering accuracy higher, which can control sand better.


2.Higher filtering accuracy:all-welded wedge wire screens as screen jacket with vee opening design makes the filtering accuracy higher, which can control sand better.


3.Excellent strength and resistance to deformation: The base pipe inside, the outside can be protected with the protection jacket added according to requirements, the integrated,strength of the perforated base pipe only decreases 2~3% compared with the standard casing/oil tubing, so the pipe based well screens have enough integrated strength to resist to the pressure caused by strata. Even if some part of the well screens deformed, the slot of this part will not be widened, which makes higher sand control reliability.


4.More choices: the material of screen jacket can be stainless steel or carbon steel, the material can be chosen as per customers'requirement.


5.The smaller slot will increase the oil and gas production.


6.The excellent technique makes the mass production with high efficiency and low cost available.
