1. Basic Structure and Function
Composition: Consists of a straight pipe section and flanges at both ends (circular disc joints with bolt holes) welded or integrally cast.
Core Functions:
Enables rapid connection and disassembly of pipelines and equipment (such as valves, pumps, and storage tanks);
Ensures the sealing of high-pressure fluids (crude oil, natural gas, etc.) during transportation, preventing leaks;
Buffers stress caused by thermal expansion and contraction or vibration of pipelines.
2. Core Application Scenarios in the Petroleum Industry
Oil Pipelines: Serves as sections of main pipelines, adapting to long-distance transportation needs;
Refining and Chemical Units: Used for the transmission of high-temperature and high-pressure media in reactors, heat exchangers, etc.;
Maintenance Scenarios: Flange design facilitates rapid replacement of faulty pipe sections, reducing downtime.
