To evaluate the steel, researchers have extensively explored factors affecting its mechanical properties during extended service.
However, the increase in these factors would negatively influence the mechanical properties of the pipeline steel.
The formation of carbides depends on factors such as chemical composition, working time and temperature, and manufacturing conditions [7-11].
These results suggest that the load strongly affects the mechanical properties of steel P22 at high temperatures.
Fig. 5 showed no differences in carbide size and distribution with increasing load, suggesting that carbides did not affect the mechanical properties of steel P22.

The properties of grease vary which depend on environmental conditions.
In this paper the modeling of grease dispensing process using artificial intelligence method, fuzzy logic to optimize the flow of grease by considering the factors affecting the flow of grease and usage of automated system for grease dispensing process.
Flow of grease is affected by 2 factors slip at the boundary and fracture of sample.
Grease with different composition and its effect on friction properties of grease in its flow is conducted using experimental set up.
This variation in properties affects the output quantity of grease discharged.

However, water contact angle was not affected with it.
Chitosan possesses good mechanical properties, thus its film is tough, long-lasting, flexible and difficult to tear.
The Effect of Coating Layer Density It is a fact that the final barrier properties of coated paper is affected by chitosan concentration, beeswax composition and drying temperature.
An indirect factor, coating layer density which was calculated based on the coating weight and thickness, was used to combine these three direct factors together.

Profile geometry and current configuration are alternated in experiment and thought as the major factors influencing deposit surface roughening.
The results show that the surface of the deposits obtained by pulse electroforming has better performance in deposit thickness distribution and properties of the deposits.
The chart illustrates that deposition distribution depends, to a great extent, on the geometric and dimensional factors.
Properties.

There are many factors that affect the safety and reliability of large winding hoist's cylinder shell structure,and most of them are of more or less randomness,But,in the reliability analysis of tube shell structure, For factors on the tube shell vary from degrees of structural failure.
Therefore, It is of great significance to study the size of the various factors that affect the reliability of the tube shell structure.
Limited by factors such as material property, structure and size, load, the cylinder shell of large-scale twining type lifting machine has been one of the most important factors influencing the hoist operation safe of the mine all the time.
Suppose there are n factors influencing the structure failure, then the matrix 3×n composed by these n sensitive vector is called the sensitivity matrix affecting this structure failure.
