Dalian flange: Multi material adaptation to meet the challenges of complex working conditions
In the vast pipeline network of industry, Dalian flange, as a key connecting component, bravely shoulders the heavy burden of dealing with complex working conditions with its multi material adaptability.
In the field of chemical engineering, highly corrosive acidic and alkaline solutions often flow through pipelines, and flanges made of ordinary materials will be corroded and riddled with holes within a few days. At this moment, stainless steel flanges step forward, rich in alloy elements such as chromium and nickel, which can form a dense passivation film on the surface, effectively blocking acid and alkali corrosion, ensuring the sealing and stability of pipeline connections, making the connections between various reaction vessels and conveying pipelines on chemical production lines as solid as rocks, and ensuring the safe transportation of high-risk chemicals.
Faced with the rigorous challenges of ocean engineering, the high salinity, strong corrosiveness, and variable water pressure of seawater pose extremely high requirements for pipeline systems. The flange is made of alloy steel material that is resistant to seawater corrosion. This material has undergone special heat treatment and has a tight internal structure. It can not only resist the erosion of salt, but also has excellent compressive performance. In the laying of subsea oil and gas pipelines, a large number of alloy steel flanges are tightly connected to each section of the pipeline, which is not afraid of deep-sea high pressure and corrosion, and provides a reliable channel for energy extraction and transportation.


The high temperature and high pressure environment is also where Dalian flange excels. In thermal power plants, the temperature inside the steam pipeline can reach hundreds of degrees Celsius and the pressure is very high. Carbon steel flanges have become the choice due to their excellent high-temperature strength and cost-effectiveness advantages. They can withstand the erosion and internal pressure of high-temperature steam, ensuring reliable pipeline connections between core equipment such as boilers and turbines in power generation systems, and ensuring stable power output.
From the low-temperature pipelines at polar scientific research stations to the hot oil pipelines in desert oil fields, Dalian Flange precisely adapts materials according to different working conditions, adapting to various changes and firmly locking the pipeline system, and continuously injecting stable power for industrial development to overcome numerous difficulties and obstacles
