Our products have fully welded ball valve ,ball valve, check valve, butterfly valve, plate valve and so on , the fittings of valve for example plate for gate valve, ball body for ball valve are also our products .
The Special Surface Complex Technology is used in our products for sealing surface.It can functioned much better at the character of wear resistance, corrosion resistance, heat-resistance, anti-oxidant and anti-permeability etc.The Special Surface Complex Technology can meet the technical requirement, of which the spraying, electroplating and welding methods cannot meet.
Brief introduction as follows:
The advantages of the special technology is that the treatment can produce a function thin layer of which the special ability can put up much more better the material itself.Different directions and technical schemes can be provided according to the requirement and process of the client.The thickness of the layer are currently 0.5mm and even less, but it can functioned much better at the character of wear resistance, corrosion resistance, heat-resistance, anti-oxidant and anti-permeability etc.
The surface complex technology is a special metallurgy technology, which cannot be affected by the shape, structure and point of the work piece, and the material of complex layer cannot be diluted.The complex technology can make the ground material and the special layer integrated tegother, which can also upgrade the characters of rigidity, corrosion-resistant, high temperature-resistant and the oxidation-resistant.The connection between the ground material and the special layer is the metallurgy connection, which can meet the technical requirement, of which the spraying, electroplating and welding methods cannot meet.
The special technology can function as consolidation, respire, pre-protect of the special parts, which can also prolong the service life and renew the value for using.The special technology can largely economize the resource without any pollution.
Application of the technology
The technology can widely applied to the steel & Iron industry, metallurgy, machinery, power, petroleum, building material, food & edible oil supplies and foodstuff etc.
Technical features of the special alloy coat layer
Thickness of the coat layer:According to the work condition of the pieces.
Rigidity of the coat layer:- HRC71
Temperature range of the layer ??1300 centigrade
