Description
304 316 Stainless Steel Double Ended Threaded Pipe NPT BSPS High-Pressure Custom Length
I. Core Structure and Technical Parameters
1. Basic Design
  • Bidirectional Thread Structure: Both ends are processed with complete external threads (some models can be customized with internal threads), and the middle part is a smooth tubular main body, forming a full-bore design, suitable for fluid transmission or mechanical connection.
  • Thread Standards:
    • British Threads: BSPT (tapered pipe threads), BSPP (parallel threads), compliant with ISO 7/1 standards, with excellent sealing performance, suitable for high-pressure scenarios.
    • American Standard Threads: NPT (tapered pipe threads), compliant with ASME B1.20.1, compatible with North American pipeline systems.
    • Metric Threads: M6-M100, with pitches of 1-6mm, supporting customization of special thread forms (e.g., trapezoidal threads) for non-standard requirements.
2. Materials and Performance
  • Main Materials:
    • 304 Stainless Steel: Resistant to acid and alkali corrosion, with a salt spray test result of ≥1000 hours, suitable for food, pharmaceutical, and chemical equipment.
    • Carbon Steel (Q235B): Tensile strength ≥375MPa, with a galvanized (8-12μm) or nickel-plated (10-20μm) surface; neutral salt spray test shows no rust for 24 hours.
    • Copper Alloy (H62): Excellent thermal conductivity, suitable for refrigeration systems or weak current connections.
  • Pressure Resistance Rating:
    • Stainless steel material: Regular models can withstand pressure ≤16MPa; thickened models can reach 40MPa (e.g., DN25 stainless steel threaded pipes).
    • Carbon steel material: Standard models can withstand pressure ≤10MPa; high-pressure models (wall thickness ≥6mm) can reach 25MPa.
3. Size Specifications
  • Diameter Range: DN6 (1/8") to DN100 (4"), covering the full range from 1/8-inch to 4-inch pipes.
  • Length Range: Regular in-stock lengths are 30-300mm; customization is supported for a maximum length of 2000mm (e.g., DN15*1000mm stainless steel threaded pipes).
  • Precision Grade:
    • Ordinary grade: Thread pitch diameter tolerance ±0.05mm, suitable for general connections.
    • Precision grade: Grinding-level pitch diameter tolerance ±0.01mm, suitable for high-precision equipment (e.g., semiconductor production lines).
II. Core Advantages and Application Scenarios
1. Performance Advantages
  • Dual Sealing Design:
    • Tapered threads combined with anaerobic adhesives (e.g., MXBON thread sealant) form a "mechanical engagement + chemical sealing" dual guarantee, with a leakage rate ≤0.01mL/min.
    • Some models have built-in O-rings (fluororubber or silicone), with pressure resistance ≥25MPa, suitable for dynamic vibration environments.
  • Fatigue Resistance Characteristics:
    • Carbon steel materials undergo quenching and tempering (hardness HRC28-32), capable of withstanding more than 100,000 alternating loads (e.g., hydraulic systems).
    • Stainless steel materials undergo solution treatment, with tensile strength ≥520MPa, suitable for high-temperature (-200℃~+400℃) occasions.
2. Typical Applications
  • Fluid Transmission Systems:
    • Chemical pipelines: 304 stainless steel threaded pipes connect reaction kettles and valves, resistant to strong acids and alkalis.
    • Refrigeration equipment: Copper alloy threaded pipes connect compressors and condensers, ensuring no refrigerant leakage.
    • Fire protection systems: Carbon steel galvanized threaded pipes are combined with grooved joints to quickly build sprinkler networks.
  • Mechanical Fastening Fields:
    • Automobile manufacturing: Double-ended threaded pipes fix engine blocks and brackets, with a torque range of 80-350N·m.
    • Construction machinery: M30*300mm carbon steel threaded pipes connect tower crane standard sections, with a tensile load ≥800kN.
  • Special Scenario Adaptation:
    • Medical equipment: 316L stainless steel threaded pipes connect CT machine slip rings, with a surface roughness of Ra≤0.8μm.
    • Aerospace: Titanium alloy threaded pipes (TC4) are used in aircraft hydraulic pipelines, featuring lightweight and resistance to extreme temperatures.
