Stainless steel 316l passive water intake screens

Stainless steel 316l passive water intake screens

Stainless steel 316L Passive water intake screens can withdraw water uninterruptedly from lakes, rivers and oceans at a low, uniform velocity.

Sino can design the intake screens according to customers’ requirements.

Various stainless steel alloys can be used to construct intake screens for fresh and sea water applications.

The intake screens cost less to install and operate and require less maintenance.

The advance of the Stainless steel 316L Passive water intake screens (wedge wire screen, v-shape well screens)

The v-shaped wire can be made in different height and width to address various strength application, meanwhile, the spacing of individual slots can be varied during fabrication if geologic conditions require these variations in a screen’s construction.

Structural Principle:

Stainless steel 316L Passive water intake screens is a key equipment widely used in seawater treatment, which can effectively filter seawater and protect subsequent processing equipment from particles and organisms.
* In seawater desalination plants, passive intake screens are used to filter impurities and particles in seawater, to ensure a
smooth subsequent desalination process.
* In marine engineering construction, passive intake screens are widely used in seawater cooling systems and seawater extraction systems. The stable structural design protects engineering facilities from damage and ensures the stable operation of the systems for a long time.
* In the field of marine ecological conservation, passive intake screens are used to reduce the capture and impact on marine organisms. Its micro-hole design minimizes interference with marine organisms, and protects the integrity and stability of marine ecosystems.

Advantages And Features:
1.lower cost
2.Reliable water supply
3.Reducing maintenance costs
4.Environmental protection
5.Bio-anti-fouling screen material
6.Protect the fish and other sea creature
7.Very low slot velocity(usually less than 0.5 f/s / 0.135 m/s) and uniform flow
What is wedge-wire and how it's made
Wedge wire screens are manufactured by resistance welding V-shaped wire on support rods. Our wedge wire screen begins with the highest quality raw wire then is made into screen that is cut, shaped, fabricated and cleaned. Wedge wire can be ordered as raw screen material or fabricated to a finished product to suit your application requirements. The pin point control over the specifications of the slot is what allows Screen to provide its customers with highly accurate flow distribution and effective media, debris and sediment filtration. Support Rods running perpendicular to the wrap wire strengthen and maintain the proper design configuration of the screen allowing it to handle intense pressure demands.
Our Wedge Wire Screen is designed to control various processing conditions including volumetric flow rate, minimum dimensional media retention, minimum open area and fluid pressure capabilities. Screen is able to professionally work a large variety of stainless steels and alloys into both standard or customized screen applications and accessory products.
 
Our screen can be welded to nipples, couplings, pipe, or flanges.The fabricated and welded construction makes for durable quality vessel internals and media retention products. Wire mesh and perforated pipe may be less expensive initially, but wedge wire screens offer easier installation and long-term operating and cost benefits.
Screens are available in slot sizes ranging from 0.001 in. (25μm) up to (1/2"). The most common material of construction is 300 series stainless steel, however many exotic alloys are available upon request such as SS321, SS304,SS316L,TA2,Duplex SS, Alloy 20, Copper Nickel, Hastelloy C-276, Alloy B-3, Monel 400. Screen diameters range from 0.750 in. to 38" in size straight from our machines. Screen can be fabricated in upwards to 52" O.D in two or more sections depending on the requirements. Screens also are made in various different configurations, including cylindrical, flat, specialty shapes or curved.

Many different variations of wire and rod sizes/profiles can be selected to develop the exact screen of your choice.Any process or vessel requirements can be accommodated, such as vertical or horizontal vessels.
