With latest technology used in the production process there is a continuous demand for effective filtration with minimum slot opening which conventional woven wire mesh screens failed to provide. Wedge wire screens are welded wire screens with very minimum slot opening which behaves like a pipe and withstand huge suction or discharge pressure where by effective filtration takes place due to very sturdy structure of the same.

Manufacturing Process
Wedge wire screens are made out of triangular wires welded to flat wires to form a panel or ring . Continuous length triangular wires are welded to flat wire panels with special precision die tools in order to achieve the desired opening. The flat wire panels are holded in a die tool where by the triangular wires are moved in a traverse like a typical lathe machine application where by the welding takes place and the movement of the traverse determines the slot opening of the mesh.

Several die tolls with diameter range from 15MM to 700MM are developed and maintained in order to make screens with different aperture openings. The screens with smaller slot openings are made initially in cylindrical form and then cut and opened and flattened in order to achieve the flat opening screens.
Usage & advantage
High pressure filtration applications and in typical filtration applications where strong screens are required wedge wire screens are used. The usage of the screens provides the end user with effective filtrations with slot opening control maintained at the range of 0.1MM you achieve a screen which is very firm due to the support structures.

Wedge wire screens are used as well screens in the rigging application and quality wire can design and supply screens typically strong enough to be used in this rigging applications.

Typical Sand screens ; rigging screens; sea water intake screens; high pressure intake screens ;catalyst bed for dumping the catalyst are manufactured and supplied by Quality Wire Products Co W.L.L.. Besides for any application where a strong filtration system is required wedge wire screens can be used and the same offers effective solutions for filtration.

Usage and applications
Knitted wire mesh is used as mist eliminator; insulation blanket mesh and also as filters & air bags for automotive industries.

In the refinery or oil and gas production process removal of mist or moisture from the gas becomes a critical process. Generally gas tends to absorb the moisture so effective removal of moisture plays a vital role in the refinery application.

The knitted wire mesh is a set of wire looped and interlaced by knitting on a circular knitting machine and then corrugated to form a zig zag pattern. Several of these layers of knitted wire mesh are installed together and further reinforced or welded with grids in specific patterns according to the customer requirements.

The mist eliminator installed inside the typical application having high surface area and due to the zig zag pattern obstructs the flow of gas resulting in creating an obstruction to the moisture content. Due to countinous obstruction to the moisture the moisture will form into a tiny droplet and due to gravity will fall down to the liquid.

Several types of mist eliminators are used in different applications based on the end use and quality wire offer Wide range of mist eliminators both in metallic and non metallic types suitable for different applications.

Our process engineers developed software for evaluating the performance of the mist eliminator based on industry standards and our products are well accepted .

Mist eliminator plays vital role in effective performance of the end use application and besides offering only the demister pads our engineers offer solution to the customer with relation to enhanced removal efficiency thus resulting in best performance of our pads.

Quality
Our wire mesh is made with precise mesh opening and with specific controls in our welding process we ensure the best quality welding. Each lots are identified with batch and lot numbers and These panels are checked for chemical composition of the raw material; mesh opening and wire diameter tolerances and welding and shearing strength before it is delivered to our customer. This helps us to deliver the wire mesh panels exactly as per customer requirements.
Coating
Welded wire mesh in steel is either hot dip galvanized or powder coated according to the requirements of the customers. Pre-galvanized wires are used to make the hot dip galvanized welded wire mesh and in some cases the mesh is made in mild steel and then hot dip galvanized according to the requirements of the customers.
Inventory/ Shipment
With wide range of welded wire mesh products manufactured and supplied in the above mesh specifications we maintain minimum stock level on our mesh products which allow us to pack and ship the goods immediately upon order confirmation. This immediate shipment concept works very well in many of the critical applications where by our customers are immensely benefit as this helps in reducing our customers down time.

With very narrow openings and with gratings which can withstand heavy payload Quality wire is specialized in supplying the same with extreme precision and best quality. Narrow opening gratings are very difficult to make as with close weldings there is extreme stress on the material there by the gratings tend to bend. With special controls and specialized after production process we achieve a obsolute flat panel even with such narrow openings. Stainless Steel and other high end alloys require precise control during process and we have specialized welding machines which produces the gratings with absolutely zero defects. Special cleaning process is used in making the grating panels there by we achieve the best surface finish on the gratings after welding. Our custom made gratings are very popular in the filtration process and used as Catalyst bed in the refinery and other oil & gas industries. Besides offering the gratings our engineers are capable of designing specific model gratings which can withstand high load and also design gratings for high pressure drop applications.
