Oil & Gas

As the worldwide demand for energy, as well as synthetic oil products continued to expand, the demand for crude oil is also increasing. Crude oil contains many pollutants, exploration equipment are in need of crude oil in the rough and pollution of the environment is very long, and it is impossible to carry out regular maintenance and replacement. Acidic crude oil, for example, at high temperature and pressure that they often contain hydrogen sulfide, sulfur dioxide and sodium chloride salt.

 

The countermeasure is to use more corrosion resistant alloy (usually nickel - chromium - molybdenum alloy) to make the related equipment. As the price of these materials are quite expensive, we usually surface to reduce costs. For example, you can use a large iron-based material strength characteristics to produce structural parts, and then a nickel-chromium-molybdenum alloy cladding layer made to improve corrosion resistance. Such consumables can be used for customer choice in the field have NiCrMo-3 (Inconel 625), NiCrMo-4 (INCO-WELD C-276), NiCrMo-10 (Inconel 622).
