Bidirectional Thread Structure: Both ends feature complete external threads (internal threads available on custom models) with a smooth tubular main body, forming a full-bore design ideal for fluid transmission or mechanical connections
Thread Standards:
British Threads: BSPT (tapered pipe threads), BSPP (parallel threads) compliant with ISO 7/1 standards, offering excellent sealing performance for high-pressure applications
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 including trapezoidal threads for non-standard requirements
Materials and Performance
Main Materials:
304 Stainless Steel: Resistant to acid and alkali corrosion with salt spray test results ≥1000 hours, suitable for food, pharmaceutical, and chemical equipment
Carbon Steel (Q235B): Tensile strength ≥375MPa with galvanized (8-12μm) or nickel-plated (10-20μm) surface treatment; neutral salt spray test shows no rust for 24 hours
Copper Alloy (H62): Excellent thermal conductivity, ideal for refrigeration systems or weak current connections
Diameter Range: DN6 (1/8") to DN100 (4"), covering full range from 1/8-inch to 4-inch pipes
Length Range: Regular in-stock lengths 30-300mm; custom lengths up to 2000mm supported (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)
Core Advantages and Application Scenarios
Performance Advantages
Dual Sealing Design:
Tapered threads combined with anaerobic adhesives (e.g., MXBON thread sealant) provide "mechanical engagement + chemical sealing" dual guarantee with leakage rate ≤0.01mL/min
Some models feature 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 over 100,000 alternating loads (e.g., hydraulic systems)
Stainless steel materials undergo solution treatment with tensile strength ≥520MPa, suitable for high-temperature applications (-200℃ to +400℃)
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 combined with grooved joints for quick sprinkler network assembly
Mechanical Fastening Fields:
Automobile manufacturing: Double-ended threaded pipes fix engine blocks and brackets with torque range of 80-350N*m
Construction machinery: M30*300mm carbon steel threaded pipes connect tower crane standard sections with tensile load ≥800kN
Special Scenario Adaptation:
Medical equipment: 316L stainless steel threaded pipes connect CT machine slip rings with surface roughness Ra≤0.8μm
Aerospace: Titanium alloy threaded pipes (TC4) used in aircraft hydraulic pipelines, featuring lightweight construction and extreme temperature resistance
