How to choose a suitable Dalian flange for specific working conditions?
In the construction and maintenance of pipeline systems in the industrial field, choosing Dalian flanges that are suitable for specific working conditions is like selecting "customized armor" for the project, which directly affects the stability and safety of operation.
The characteristics of the medium are the primary consideration factor. In the chemical industry, pipelines transporting highly corrosive media such as acid and alkali can instantly corrode ordinary carbon steel flanges. At this point, stainless steel flanges are a wise choice, such as 316L stainless steel flanges, which are rich in molybdenum elements and can form a strong protective film in harsh corrosive environments, ensuring that pipeline connections are not penetrated by corrosion and allowing the chemical process to be continuous and stable. In the field of food processing, to prevent contamination, flanges that come into contact with materials must comply with hygiene standards. 304 stainless steel flanges stand out for their good corrosion resistance and ease of cleaning, ensuring product quality and safety.

The temperature conditions cannot be ignored. High temperature conditions, such as hot oil pipelines in refineries and steam pipelines in thermal power plants, often exceed several hundred degrees Celsius in temperature. Heat resistant alloy steel flanges have become the best choice, as they undergo special heat treatment processes to maintain high strength and stability at high temperatures, effectively preventing deformation, ensuring tight pipeline connections, and smooth medium transmission. In the low-temperature field, such as liquid nitrogen and liquid hydrogen transportation pipelines, low temperatures can easily cause material brittleness. Aluminum alloy or low-temperature steel flanges, with their excellent low-temperature toughness, can avoid the risk of brittle fracture and ensure the safe transportation of low-temperature fluids.
The pressure bearing requirements are equally critical. In high-pressure natural gas transportation and deep-sea oil and gas extraction pipeline systems, pressure tests the pressure bearing capacity of flanges. High strength forged flanges enhance the internal structural density through special forging processes, capable of withstanding extremely high pressures, ensuring that pipeline systems do not leak or burst, and safeguarding energy transmission.
In addition, for areas or equipment with seismic requirements, such as water and gas supply pipelines in earthquake active zones and offshore oil platforms, flanges with flexible connection design and shock-absorbing structures can buffer stress during vibration, stabilize pipeline connections, and ensure smooth operation of lifeline projects. Accurate analysis of working conditions and comprehensive consideration of various factors are necessary to select Dalian flanges that meet the requirements and lay a solid foundation for industrial pipeline systems.
