Global Supply, Borderless Service, Superior Strength & Toughness A182 stainless 304 ASME B16.5 Alloy Steel Flanges Blind NPS 3 1/2 " Class 150

1. Product Description

Jin Gang Flanges do not refer to flanges made of gold or a special metal called "Jin Gang," but rather represent high-performance pipe connectors crafted from high-quality steel and treated with special processes to make them as strong and durable as diamond. Manufactured from premium carbon or alloy steel through forging, heat treatment, and precision machining, they are used to connect pipes, valves, pumps, and other equipment to form a sealed and reliable piping system. They are indispensable key components in industrial fluid transportation.

2. Key Product Parameters

3. Product Applications

Jin Gang Flanges are widely used in low-pressure, normal-pressure, and medium-high-pressure piping systems across various industrial sectors, offering exceptional versatility:

• Water Conservancy & Drainage: Water treatment plants, sewage treatment plants, municipal pipe networks.

• Construction & HVAC: Building central air conditioning, fire protection pipelines, ventilation systems.

• Low-Pressure Industrial Piping: Compressed air, circulating water, low-pressure steam systems.

• General Machinery: Interface connections for pumps, valves, compressors, storage tanks.

4. Product Advantages

• High Strength & Rigidity: High-quality steel and forging processes ensure strong pressure-bearing capacity and resistance to deformation.

• Excellent Economy: Offers significant cost advantages compared to stainless steel and alloy steel flanges while meeting operational requirements.

• Good Machinability & Weldability: Uniform material properties facilitate on-site cutting, welding, and installation.

• Diverse Surface Treatments: Anti-rust oil, painting, galvanizing, and other surface treatments are available to meet various environmental needs.

​

5. Product Functions

• Reliable Connection: Securely connects pipe sections to other pipe sections or equipment, forming continuous pressure pipelines.

• Easy Maintenance: The flanged connection structure allows for convenient disassembly and installation of pipeline sections, simplifying daily upkeep and repairs.

• Change Pipeline Direction/Size: Enables changes in pipeline direction or diameter when used with flanged elbows, flanged reducers, and other pipe fittings.

• System Sealing: Provides effective sealing at connection points by compressing gaskets, preventing fluid leakage.
