The original refining low sulfur crude oil enterprise generally faces improvement of equipment and upgrade materials, various accidents caused by corrosion is straight up, as in [1].
Corrosion caused by sulfur and naphthenic acid on refinery equipment Petroleum and natural gas are mined from underground, transported to the petroleum chemical plant of refining processing, and changed into various organic chemical raw materials and products.
From raw materials to products, a variety of devices and pipelines of exposure and processing are corrosive medium, many physical processes and chemical reactions need under stressful conditions can be carried out, or the need to increase the temperature, using a catalyst to accelerate the reaction speed.

Composite support structure of continuous arch internal support design and calculation and analysis of engineering example Hongxia Li1, a Yanqin Guo2, b Yongwei Wang3, c 123Huanghe Science and Technology College Institute of Technology, Henan Province, china a737801521@qq.com, b27669932@qq.com，c65839177@qq.com Keywords: composite support structure; continuous arch; internal support; calculations Abstract: Composite support structure of continuous arch internal support is a new type of maintenance structure of deep foundation.
The arch supporting structure and internal bracing combination, for the strip pit groove project, can not only solve the problems of foundation pit precipitation, but also can effectively reduce the arch supporting structure in the vertical bending moment in the process of excavation and supporting construction difficulty, so that the combined supporting system in horizontal earth pressure under the action of main produce axial pressure, give full play to the mechanical properties of materials[2].
Cement soil pile is arranged into an arched shape, altered gravity retaining wall or plate retaining structure form, in the horizontal earth pressure under the effect of hand can use soil around the arch action, reduce the effect on supporting structure of soil pressure; on the other hand, reasonable structure stress, arch wall material basically compression, fully play the strength of soil-cement.

Material of specimen was carbon steel with the ultimate strength 520 MPa.
This material has high thermal conductivity, it removes heat from the crop point.
We must not forget also the savings of the material costs.

Introduction: Aluminum is a corrosion resistance material which is widely used in aerospace applications doesn’t have appropriate wear resistance by itself.
The excellent field performance of zinc coatings results from its ability to form dense, adherent corrosion product films and a rate of corrosion considerably below that of ferrous materials [1] Titanium nitride (TiN) coated on aerospace Al7075-T6 in different conditions using PVD magnetron sputtering technique shows that the hardness of titanium nitride-coated specimens is increased significantly up to 720 HV, while the hardness of uncoated specimens was only 170 HV[2].
There is a strong dependency of the fatigue strength on the deposited material and the processing parameters [3].

Experimental Procedures Amorphous tantalum precursor was used as the starting material to promote the nitration reaction.
To synthesize the starting material, 110ml of hydrochloric acid and 24ml of methanol was mixed to create a 5mol% solution.
To synthesize nitrides with this precursor as the starting material, nitration treatment was conducted in an electric furnace containing an N2 and NH3 gas atmosphere (0.5 L/min) at 1000°C for 5 hours.

The S-FEM has been applied to diverse range of application such as heat affected zone material [2,3], corrosion cracking [4], crack closure effect [5] and composite material [6].
Improvement need to be made for simulation since Paris coefficient C, initial crack length and other material properties cannot be treated deterministically.
