Quantity
The Threaded Pipe Flange is manufactured in accordance with the ASME B16.5 standard, made from SS304 stainless steel, and produced through forging to ensure high strength and durability. The flange specifications cover sizes from 1/2 to 24 inches, with a pressure rating of 150LB and a raised face (RF) sealing surface. It is suitable for various applications, including water systems, oil, and gas pipelines. The threaded connection method allows for easy installation, making it particularly ideal for space-constrained areas or situations requiring frequent disassembly.
The high strength and durability of the Threaded Pipe Flange are primarily attributed to its forging process. Forging is a manufacturing technique that involves applying pressure to a metal billet to induce plastic deformation, significantly enhancing the material's mechanical properties and structural integrity.
1. Overview of the Forging Process
The forging process is divided into two types: open-die forging and closed-die forging. The Threaded Pipe Flange typically employs closed-die forging, where heated stainless steel billets are placed into molds and shaped using presses or hammers. This process allows precise control over the flange's shape and dimensions while improving the material's internal structure.

2. Enhancement of Material Properties Through Forging
Increased Material Density: During forging, the metal billet undergoes plastic deformation under high pressure, compressing internal pores and defects to form a dense structure. This density significantly improves the Threaded Pipe Flange's compressive strength and impact resistance.

Refined Grain Structure: Forging refines the metal's grain structure, enhancing the material's strength and toughness. According to materials science theory, finer grains result in better mechanical properties.
Improved Mechanical Properties: The forged Threaded Pipe Flange exhibits higher tensile strength, yield strength, and fatigue strength. For example, SS304 after forging can achieve a tensile strength of ≥515 MPa and a yield strength of ≥205 MPa, far exceeding products made by casting or sheet processing.
3. Performance Under High-Pressure and High-Temperature Conditions
High-Pressure Conditions: The Threaded Pipe Flange is commonly used in pipeline systems with pressure ratings of 150LB, 300LB, and 600LB. The forging process ensures that the flange can withstand working pressures up to 42 MPa (600LB rating) without deformation or leakage.

High-Temperature Conditions: Stainless steel inherently offers excellent high-temperature resistance, and the forging process further enhances the Threaded Pipe Flange's thermal stability and creep resistance. SS304 flanges can operate stably within a temperature range of -20°C to 400°C, while SS316 flanges can be used in an even wider range (-20°C to 600°C).
4. Advantages of the Forging Process
High Strength: Forged flanges are 20%-30% stronger than cast flanges, enabling them to withstand higher pressures and loads.
High Strength: Forged flanges are 20%-30% stronger than cast flanges, enabling them to withstand higher pressures and loads.
Long Service Life: Forged flanges exhibit excellent fatigue resistance and corrosion resistance, with a service life exceeding 20 years.
Safety and Reliability: The forging process reduces internal defects, ensuring the Threaded Pipe Flange operates safely under harsh conditions such as high pressure, high temperature, and corrosive media.
The high strength and durability of the Threaded Pipe Flange manufactured through forging have been thoroughly validated. Whether in high-pressure, high-temperature, or corrosive media environments, forged flanges demonstrate exceptional performance and reliability, making them the preferred choice for industrial pipeline systems.
