PTA Powder
Main application:Repair and
strengthen workpiece surface, significantly
Welding method:PTA welding
Main equipment:PTA welding
machine
Flame core temperature: about 10000℃
Technological characteristics:PTA has high
temperature, concentrated energy, stable combustion, small heat affected zone,
fast welding speed, high production efficiency, easy to obtain low dilution
rate of surfacing layer, surfacing layer and workpiece matrix are metallurgical
bonding,, bonding strength is high.
PTA welding technology is one of surface
strengthening methods, which has high deposition rate, low dilution rate, and
could be applied with many kinds of powder. The manufacturing craft of PTA
powder is normally gas atomization, which reduces satellite of powder. We
supply 4 main categories of PTA powder: Nickel-based alloy powder, Iron-based
alloy powder, Cobalt-based alloy powder and Mixed Powder .
Nickel Based Alloy Powder possesses high
temperature resistance and wear resistance, it is the most popular alloy powder
applied by PTA welding both domestically and internationally. Coating hardness
is within the range of HRC 30-60. It could be applied to various industries
like agriculture, plastic, paper, marine and steel making where wear and
corrosion protection needed. Some examples are plunger, moulds, pump leaf and
screw.
Iron Based Alloy Powder is more widely used
and a more economic choice. With high abrasive resistance, it is more commonly
applied to mining tools, drilling tools and mixers of iron and steel making
industry, coal industry, shaft, oil and energy industry.
Cobalt Based Alloy Powder is recommended
for corrosion and oxidation resistance, with better hot hardness values than
equivalent Nickel based alloy powder. It is widely applied to steel making
industry, coal industry and mining industry.
Mixed powder mainly refers to NiCrBSi
mixing with other hard-phase powder such as cast tungsten carbide and other cemented
alloy powder, which allows the powder better hardness around HRC60 and
excellent abrasion resistance.
Mixed powder is more often used for mining
equipment for oil sands, lignite, oil drilling tools, excavator buckets,
extrusion screws for plastic processing, grain and oil processing, etc.

Monel 400 stainless steel v-wire water well screen

Construction for wedge wire screen pipe
Rods spaced evenly around the circumference support the screen and prevent the screen from deformation.
V-shaped wire produces self-cleaning action and non-clogging performance. The slot width on surface is increasing towards the internal side of the screen. This slot geometry is called keystone slot which has the ability of anti-plugging. Precise slot width should be designed to satisfy operation requirements. Usually, the slot width is two times the size of the formation sand.
End fittings can be customized to secure the screen body.

Materials for wedge wire screen pipe
Wedge wire screens are made of stainless steel wire, which is the most popular type because of outstanding chemical stability and corrosion resistance.
Wedge wire screens are usually fabricated by stainless steel 304 and 316L, low carbon steel, galvanized steel. However, optional temperature is another important element to be considered. So, wedge wire screens made of other materials are at stock, including Monel 400, Hastelloy (C4, C22, C276) and Inconel 600.
