Application of Thermal Spray Technology in Chemical Petroleum Industry

       In the chemical industry, corrosion is particularly serious, it not only causes a lot of material and equipment losses, but also the shutdown of enterprises due to corrosion. The losses caused by safety accidents and environmental pollution are even more incalculable. Preventing "running, running, dripping and leaking" is one of the main tasks of equipment management in chemical enterprises. The thermal spraying technology, which integrates a variety of process methods and aims at surface strengthening, can spray all solid engineering materials, and has good chemical stability. It has been widely used in the chemical industry. Chemical media often contain sulfur and oxygen, such as fuel, alcohol, acetic acid, toluene, glycerin, syrup storage tanks, original shaft sleeve mechanical seals and impellers, all of which can be solved by thermal spraying. For general weak corrosive media, it can be solved by metal thermal spraying of aluminum, zinc, and stainless steel, and for strong acid and alkali, it can be solved by plastic flame spraying epoxy, PTFE, etc. The effect is very significant.



Typical applications of thermal spraying in the chemical industry are as follows:



1. Replace high-grade stainless steel such as stainless steel and titanium alloy with low-grade material and heating spray coating.



2. It can be used as anti-corrosion coating for chemical reaction tanks, storage tanks, stirring devices and pipelines.



3. It can be used as a good repair layer for glass-lined equipment broken and damaged.



Thermal spraying is also widely used in the petroleum industry. Thermal spraying has been successfully used in the repair and protection of equipment such as oil exploration and extraction. Thermal spray coatings have been successfully used for long-term anticorrosion of petroleum steel pipes and offshore platforms. The arc spraying technology introduced by the engineering installation company of an underground operation company has better solved the problem of metal anti-corrosion and filled the gap of metal anti-corrosion in the oil field. The engineering and installation company has applied this technology to wire, plate, profile and metal equipment, and the anti-corrosion ability of the sprayed product has been increased by more than 2 times.
