Large flanges have significant advantages in industrial piping systems and equipment connections, especially under high pressure, large diameter or complex working conditions. The following are its main advantages:
1. High strength and pressure bearing capacity
High pressure resistance: thick design and high-quality materials (such as carbon steel, stainless steel, alloy steel), suitable for high-pressure piping systems (such as petroleum, chemical, and power industries).
Anti-deformation: The structure is stable and can withstand pipeline vibration, thermal expansion and contraction or external loads, reducing the risk of leakage.
2. Excellent sealing performance
Multiple sealing surface options: flat surface (FF), convex surface (RF), ring joint surface (RTJ), etc., to match different media requirements (such as high temperature, corrosive fluids).
Reliable sealing materials: can be matched with metal gaskets, graphite spiral wound gaskets, etc. to ensure sealing under harsh working conditions.
3. Convenient installation and maintenance
Modular connection: simplifies the assembly of large-diameter pipes, especially suitable for confined spaces or high-altitude operations.
Easy to disassemble: easy to inspect, clean or replace parts, reduce downtime and reduce maintenance costs.
4. Adapt to complex working conditions
Resistant to extreme environments: through special materials (such as 316L stainless steel) or coating treatment, corrosion resistance, high temperature resistance (such as boiler system) or low temperature resistance (LNG pipeline).
Large diameter support: suitable for water treatment, ships and other scenes that require large flow transmission (DN1000 and above).
5. Standardization and compatibility
General standards: in line with international/national standards such as ASME, DIN, GB, etc., to ensure interchangeability with other flanges, valves, and pumps.
Flexible configuration: can be matched with flange types such as butt welding, flat welding, loose sleeve, etc. to meet different installation requirements.
6. Economy and life
Long-term durability: reduce frequent replacement and reduce overall costs.
Low leakage risk: high-quality flanges can avoid environmental or safety accident losses caused by media leakage.
Typical application scenarios
Energy industry: oil and gas pipelines, nuclear power equipment.
Chemical/pharmaceuticals: corrosive media pipelines.
Heavy machinery: inlet and outlet connections of large equipment (such as compressors and reactors).
Summary
Large flanges solve the connection problems of large-caliber, high-pressure systems through high-strength structure, excellent sealing and standardized design, while taking into account installation efficiency and long-term reliability. They are indispensable key components in industrial infrastructure. When selecting, it is necessary to comprehensively consider pressure level, material, sealing requirements and environmental factors.

How to store stainless steel tees
Stainless steel tees are high-performance, corrosion-resistant pipe fittings. While there are significant differences between tees and elbows, tees are widely used in pipeline construction. Despite their excellent corrosion resistance, care must be taken during storage to prevent quality issues.
