Definition of stainless steel(Adopted form Wikipedia)
In metallurgy, stainless steel, also known as inox steel or inox from French "inoxydable",
is defined as a steelalloy with a minimum of 10.5% to 11% chromium content by mass.
Stainless steel does not readily corrode, rust or stain with water as ordinary steel does,
but despite the name it is not fully stain-proof, most notably under low oxygen, high salinity,
or poor circulation environments. It is also called corrosion-resistant steel or CRES
when the alloy type and grade are not detailed, particularly in the aviation industry.
There are different grades and surface finishes of stainless steel to suit the environment
the alloy must endure. Stainless steel is used where both the properties of steel
and resistance to corrosion are required.
Surface Finish :
Surface finish | Characteristics and application |
No.2B | The surface brightness and flatness of no2B is better than no2D. then through a special surface treatment to improve its mechanical properties, No2B could nearly satisfy comprehensive uses. |
No.3 | Polished with abrasive belt of git#100-#200, have better brightness with discontinuous coarse stria, used as inner and external ornaments for building, electrical appliances and kitchen utensils etc. |
No.4 | Polished with abrasive belt of grit #150-#180,have better brightness with discontinuous coarse stria, but thinner than No3, are used as bathtub buildings inner and external ornaments electrical appliances kitchen utensils and food processing equipment etc. |
HL | Polished with abrasive belt of grit #150-#320 on the NO.4 finish and has continuous streaks, mainly used as buildings ornaments elevators, door of building, frontal plate etc. |

- Q:How do you calculate the flow rate in stainless steel pipes?
- In order to determine the flow rate in stainless steel pipes, one can utilize the principles of fluid dynamics along with the properties of the fluid being conveyed through the pipe. There are several factors which must be taken into account: 1. The first step is to ascertain the diameter of the pipe. This parameter significantly impacts the flow rate as a larger diameter allows for a greater volume of fluid to pass through. 2. The second step involves determining the viscosity of the fluid. Viscosity refers to the fluid's resistance to flow. Fluids with high viscosity flow at a slower rate, whereas those with low viscosity flow more rapidly. 3. The next consideration is the calculation of the pressure drop across the pipe. This factor plays a crucial role in establishing the flow rate, and it can be computed by measuring the pressure at different points along the pipe. 4. The Reynolds number is then employed. This dimensionless value combines the fluid's velocity, density, viscosity, and pipe diameter. It aids in determining whether the flow is laminar (smooth) or turbulent (chaotic). Different equations exist to calculate the Reynolds number based on the flow regime. 5. The final step involves the application of the appropriate flow equation. Depending on the flow regime, various equations can be utilized to calculate the flow rate. For laminar flow, the Hagen-Poiseuille equation is applicable, while the Darcy-Weisbach equation or the Manning equation can be employed for turbulent flow. By considering these factors and employing the appropriate equations, the flow rate in stainless steel pipes can be determined. It is important to note that these calculations provide an estimate and may not yield exact results due to factors such as pipe roughness, fittings, and other obstructions within the pipe. Therefore, it is advisable to consult a fluid dynamics expert or employ specialized software for accurate calculations.
- Q:What are the different types of stainless steel pipe tees?

Socket Weld Connections: In this type of connection, the pipe is inserted into a socket and then welded around the joint. Socket weld connections are mainly used for smaller pipe sizes and high-pressure applications. 3. Butt Weld Connections: Butt weld connections involve welding the ends of two pipes together. They are commonly used for larger pipe sizes and high-pressure applications. 4. Flanged Connections: Flanged connections involve attaching two pipes together with a flange on each end. The flanges are then bolted together to create a secure joint. Flanged connections are commonly used for larger pipe sizes and applications requiring easy disassembly. 5. Compression Connections: Compression connections involve using a compression fitting to connect two pipes. This type of connection is particularly useful for applications that require frequent disassembly and reassembly. 6. Grooved Connections: Grooved connections involve using grooved fittings to connect two pipes. The grooves on the fittings are matched with grooves on the pipes, and then a gasket is inserted to create a seal. Grooved connections are commonly used in fire protection systems and industrial piping. Each type of stainless steel pipe connection has its own advantages and disadvantages, and the choice depends on the specific requirements of the application. It is important to consider factors such as pressure, temperature, pipe size, and ease of installation when selecting the appropriate connection type.
