Corrosion Resistance Inconel Pipe 690 Nickel Alloy Seamless Tube For Oil And Gas Industry

Introduction:

Inconel 690 pipe is a commonly used high temperature alloy pipe in the oil and gas industry. Constructed of nickel, chromium, iron and other alloying elements, Inconel 690 pipe has excellent corrosion resistance and high temperature stability.

The chemical composition of Inconel 690 tubes includes nickel (58-63%), chromium (27-31%), iron (7-11%), molybdenum (0.5% max), manganese (0.5% max), titanium (0.5% max) ) and copper (max. 0.5%). The pipe has a density of 8.19 g/cm³ and a thermal expansion coefficient of 13.3 μm/m·°C (20-1000°C). Its tensile strength can reach a minimum of 690 MPa, and its yield strength can reach a minimum of 310 MPa.

In the oil and gas industry, Inconel 690 pipe is widely used in pipes, heat exchangers and other equipment in high temperature and corrosive environments. Due to the presence of high temperatures and corrosive media during oil and gas extraction, processing and transportation, Inconel 690 pipe can provide excellent corrosion resistance and high temperature performance to ensure reliable operation of pipelines.

Inconel 690 pipe has excellent corrosion resistance and can resist the erosion of corrosive substances such as hydrogen sulfide, acidic media and chlorine-containing compounds. At the same time, it can maintain good mechanical properties and stability in high temperature environments, ensuring long-term operational reliability in the oil and gas industry.
