product details
Function Introduction Stub-end is a pipe fitting that forms the edge of the pipe mouth into a vertical edge along a specific curve through stamping or welding. It is mainly used for connecting pipes with flanges, valves, or other pipe fittings to enhance sealing and structural strength. Its design replaces complex drawing processes, optimizes material plastic flow, avoids cracking or wrinkling, reduces processing steps, and saves materials. It is especially suitable for high-pressure, corrosion-resistant, or precision fluid delivery systems.
Production Process 1. Material Selection: Stainless steel (304, 316L, duplex steel 2205), carbon steel, alloy steel, etc., customized based on working conditions.
2. Forming Process:
- Cold Forming: For small-diameter products (DN15-DN600), seamless flanging via stamping or spinning.
- Argon Arc Welding: For large-diameter products (DN600+), ensuring edge flatness and strength.
3. Quality Inspection: Spectral analysis, pressure testing, and non-destructive testing (X-ray flaw detection) to ensure compliance with standards.
Application Fields - Petrochemical: Sealing connections for oil refining units, pipelines, and reaction vessels.
- Electricity & Nuclear Power: High-temperature, high-pressure steam pipelines and nuclear cooling systems.
- Ship & Machinery: Corrosion-resistant designs for seawater media and heavy machinery.
- Food & Medicine: Stainless steel for sterile fluid delivery, meeting hygiene standards.
Specification Range - Size: DN15-DN1200 (1/2"-24"), supports custom ultra-large diameters.
- Pressure Level: Wall thickness SCH5S-SCH160, suitable for low to high-pressure conditions.
