Product Description:

Stainless steel 304 or 316;  Used for stainless steel PUMP application; Made from 304 or 316; Finishing with full machining; Customized designs are welcome; Manufacturing by inestment or lose wax casting; Pressure testing available 

 Investment casting is also known as the lost wax process. This process is one of the oldest manufacturing processes invented by the Egyptians in about 5,000 years ago. Intricate shapes can be made with high accuracy. In addition, metals that are hard to machine or fabricate are good candidates for this process. It can be used to make parts that cannot be produced by normal manufacturing techniques, such as turbine blades that have complex shapes, or airplane parts that have to withstand high temperature

 The types of materials that can cast are aluminum alloys, bronzes, tool steels, stainless steel, satellite, haste alloys, and precious metals. Parts made with investment castings often do not require any further.  

Optional Process: Mould tooling, Die Casting, Deburring, Drilling Holes, Tapping,CNC,Machining,Polishing,Surface Finishing, Assembly, Quality Inspection, Packing.

Surface Finish Option: Powder Coating, Painting, Electroplating, Anodizing, Electrophoresis, Sandblasting, Brushing, Vibratory Grinding.

Advantage: High Accuracy, Smooth Surface, High Production Efficiency.

Q:What are the high temperature resistant insulation materials at 400?
According to the general rules of equipment and piping insulation, heat insulation material is a material with a thermal conductivity of less than 0.14W/ (m*K) when the average temperature is equal to or less than 623K (350 degrees Celsius). Heat insulation material is usually light, porous, porous, small thermal conductivity characteristics. Generally used to prevent heat loss of equipment and pipes, or frozen (also known as general cold) and low temperature (also known as cryogenic) use, so in our country, insulation materials, also known as insulation or cold preservation materials. At the same time, because of the porous and fibrous structure of thermal insulation material, it has good sound absorption function, so it is also widely used in the construction industry.
Q:What are the production methods of calcium silicate board material?
At present most of the static process, the raw materials and auxiliary materials according to a certain proportion, adding an appropriate amount of water, while stirring heated to a certain temperature of the gel, and then after molding, autoclave curing, drying is calcium silicate insulation material products. In static method, diatomite is used as siliceous material, calcium material is more lime. The process is simple, low cost, but when the production needs of large capacity and high pressure kettle, the reaction is not complete, the main form of Tobey mullite type calcium silicate board, the use of low temperature (<650 degrees Celsius), it is difficult to produce light and ultra light high strength products.
Q:What's the difference between white cement and ordinary cement?
White portland cement as the raw meal with the proper components till the partial melting of the calcium silicate as the main ingredient, the iron content in clinker less addition of gypsum, white water ground made of rigid cementitious material. When grinding cement, allow limestone not to exceed 5% of the cement weight. White cement is mostly ornamental, and its manufacturing process is much better than ordinary cement. The gap is mainly used to hook white tiles, is generally not used in the wall, the reason is not high strength. It is available in the building materials market or decoration materials shop.
Q:Eterpan and yinte in what is the difference?
Eterpan:Eterpan, is a kind of fiber reinforced silicate plate (fiber cement board), the main raw material is cement, plant fiber and minerals, the flow of high temperature steam pressure and slurry method, mainly used as building materials.Eterpan is a kind of high strength, durability and other advantages of fiber silicate sheet, with various thickness and density, 100% does not contain asbestos and other harmful substances. For non combustible A1 grade products.The utility model has the advantages of fire prevention, moisture proof, waterproof, sound insulation effect, environmental protection, quick installation, long service life, etc.. Often used for wall panels, bathroom partitions, outdoor roofing, roofing, exterior insulation panels, interior decoration, ceilings, etc.; alsoInstead of gypsum board, used as base material in decoration.
Q:What's the use of white portland cement?
White portland cement as the raw meal with the proper components till the partial melting of the calcium silicate as the main ingredient, the iron content in clinker less addition of gypsum, white water ground made of rigid cementitious material. When grinding cement, allow limestone not to exceed 5% of the cement weight. White cement is mostly ornamental, and its manufacturing process is much better than ordinary cement. The gap is mainly used to hook white tiles, is generally not used in the wall, the reason is not high strength. It is available in the building materials market or decoration materials shop.
Q:What is the maximum temperature at which the glass is cured?
Glass is softened at a temperature of 600 degrees. When making glass, but ordinary alcohol lamp is enough to soften it. Glass is not crystal. The softening point of lead glass is 500 degrees. The main component of ordinary glass is CaO: Na2O: 6SiO2, which can be softened by fire. In addition to the ordinary glass, glass wire, alcohol burner 1000 degree glass has no definite melting point and freezing point, in softening products can be made into any shape, so there is no fixed melting point, clarification, fluoride special glass based raw materials, slightly higher than 1200 DEG C melting, but the softening point, as well as borate, limestone, mixed melt in glass kiln.
Q:What are the raw materials of cement products? What's the function?
Water is necessary for the production of cement products, the role of water is to cement hydration. Generally, the water cement ratio of concrete is 0.40~0.65. If the water is too large, it will leave a hole in the concrete, which will affect the strength, density and durability of the concrete and even cause water leakage.
Q:What's the use of low carbon steel insulated nail hooks for power plants?
Low carbon steel nail insulation (aka: insulation pins) material: low carbon steel wire for power plants or stainless steel wire products: insulation nail. Hook nail is a power plant by mechanical processing of special insulation nail models: nail diameter: 3 mm with 3.5mm with 4 mm with 5 mm with 6 mm etc.
Q:Which is better, asbestos free calcium silicate and aluminium silicate refractory fiber?
The two are thermal insulation materials. Calcium silicate board strength, cheap, but the use of temperature is not high, the highest 1000 degrees.
Q:Eterpan with calcium silicate is sold on the market are the same thing? Non asbestos calcium silicate board is Eterpan it
Eterpan is calcium silicate board there is a famous brand. Non asbestos calcium silicate board has many kinds, Aitken is just one.
