Our company is pleased to introduce Thread Flange-a key pipeline connector-to help you make more informed decisions in engineering selection.
I. Materials and Standards: Controllable Quality and Compliance Reliability
Material Selection: Various materials are available, including carbon steel, stainless steel (304, 316), and alloy steel. Customization can be done according to medium corrosiveness, temperature, and other working conditions to ensure compatibility between the material and the system.
Implementation Standards: Production strictly adheres to mainstream standards such as GB/T 9114 (national standard) and ASME B16.5 (American standard). Dimensional accuracy and pressure-bearing performance meet specification requirements, ensuring interchangeability with domestic and foreign pipeline systems.
II. Core Product Features: A Balance of Convenience and Safety
Thread flanges are non-welded flanges connected by screwing the internal pipe threads with the external threads of the pipeline. Their core advantages include:
Installation Flexibility: No on-site welding is required, making them especially suitable for flammable, explosive, or fire-prohibited areas or pipeline systems using hard-to-weld materials like alloy steel. This significantly reduces construction safety risks and technical thresholds.
Detachability: During later maintenance, the flange can be directly unscrewed without damaging the pipeline itself, facilitating equipment replacement, cleaning, or pipeline modification. It is particularly suitable for scenarios requiring frequent maintenance.
Sealing Reliability: When matched with appropriate gaskets, the sealing surface is compressed by the thread pre-tightening force to ensure good sealing under normal working conditions. Common sealing surface types include flat, raised, and male-female faces, meeting different sealing needs.
III. Applicable Scenarios: Accurate Matching with Working Conditions
Based on its structural characteristics, thread flanges are more suitable for the following scenarios:
Pressure and Temperature Range: Recommended for low-to-medium pressure, normal-temperature pipeline systems with a design pressure ≤ 4.0MPa and temperature ranging from -45℃ to 200℃, such as water supply and drainage, heating, ventilation, air conditioning, and low-pressure process pipelines.
Pipe Diameter Selection: They perform exceptionally well in pipelines with a diameter ≤ DN100, ensuring connection strength while controlling costs.
Industry Adaptation: Widely used in municipal water supply and drainage, fire protection systems, pharmaceutical clean pipelines, food processing equipment connections, and non-high-temperature, non-high-pressure sections of petrochemical industries.
IV. Selection Recommendations: For More Accurate Adaptation
If your project has welding restrictions or frequent maintenance needs, or if the medium is normal-temperature and low-pressure fluid, threaded flanges are an efficient and economical choice.
For high-temperature (＞200℃), high-pressure (＞4.0MPa), or strong vibration working conditions, it is recommended to use our welded flanges or other more suitable products to ensure long-term stable operation of the system.
