Product Description
British Thread Adapters Hollow Male Adapters BSP BSPT UNF Thread
Carbon Steel British Thread Hollow Male Adapters
Targeting cost-sensitive British-thread connection scenarios, this adapter integrates external thread fastening and hollow fluid passage functions. Manufactured from carbon steel (Q235/45#), it delivers high cost-effectiveness and superior strength for dry/low-corrosion environments, addressing economic connection needs for British-standard interfaces.
Material & Surface Protection
- Base Material:
- Q235: General-purpose grade, cost-effective for low-pressure (≤80bar) and dry scenarios
- 45# Steel: Quenched-tempered, with tensile strength ≥600MPa, suitable for high-pressure (≤200bar) and impact-prone scenarios
Surface Treatment Comparison
| Treatment | Appearance | Salt Spray Resistance | Applicable Scenarios | Limitations |
|---|---|---|---|---|
| Blue-white Zinc | Bright silver | 48-72 hours | Indoor dry environments | Prone to rust in humidity |
| Chromate Zinc | Rainbow hue | 72-120 hours | Mildly humid outdoors | Weaker than dacromet |
| Black Oxide | Matte black | 24 hours | Lubricated indoor environments | Rust-resistant only |
| Dacromet | Gray matte | ≥500 hours | Coastal/humid industrial areas | Higher cost, lower hardness |
Thread & Structural Design
- Thread Standards:
- Pipe Threads:
- BSPP (parallel, 55° thread angle): For low-pressure water/gas (requires gaskets)
- BSPT (tapered, 55° thread angle): Self-sealing for medium-pressure hydraulics
- Fastening Thread: UNF (fine thread, 60° thread angle): For precision gas circuits (requires face seals)
- Pipe Threads:
- Hollow Design: Through-hole diameter matches thread specifications precisely. Roller-burnished inner walls eliminate burrs, ensuring smooth fluid flow (pressure drop ≤8%)
Application Scenarios & Industry Fit
| Industry | Typical Applications | Core Advantages | Media Restrictions |
|---|---|---|---|
| Construction Machinery | Hydraulic pipeline adapters for excavators, oil circuit joints for loaders | 45# steel resists impact; chromate zinc reduces cost | Mineral oil (neutral) |
| Agricultural Machinery | Air brake systems for tractors, water pipeline connections in irrigation equipment | Q235 offers cost-effectiveness; blue-white zinc suits short-term outdoor use | Freshwater, air |
| General Industry | Cooling water pipes for machine tools, interfaces for general pneumatic equipment | Black oxide suits lubricated environments; ultra-low cost | Emulsions (mildly alkaline) |
| Low-Pressure Fluids | Temporary water pipelines in construction, air circuits for small compressors | BSPT taper enables self-sealing (no gaskets needed for quick installation) | Clean water, non-corrosive gas |
Selection Parameters (Examples)
| Model Code | Thread Type | Carbon Steel Grade | Surface Treatment | Through-Hole Dia. (mm) | Rated Pressure (bar) | Suitable Media |
|---|---|---|---|---|---|---|
| HS-C1/2-BSPP | BSPP 1/2" | Q235 | Blue-white Zinc | 8.5 | 80 | Freshwater, air |
| HS-C3/8-BSPT | BSPT 3/8" | 45# | Dacromet | 6.2 | 180 | Hydraulic oil (dry) |
| HS-C1/4-28UNF | UNF 1/4" | Q235 | Black Oxide | 3.0 | 60 | Mineral oil (lubricated) |
Competitive Advantages
- Cost Leadership: 30-50% cheaper than stainless steel equivalents for mass industrial procurement
- Strength Customization: Quenched 45# steel replaces some alloy steel joints, reducing cost while maintaining strength
- Protection Flexibility: Choose surface treatments to balance cost and service life
This carbon steel British-thread hollow male adapter focuses on "low cost + strong adaptability". Through tailored surface protection, it expands application boundaries, becoming the preferred British-standard connection solution for budget-sensitive fields in dry/low-corrosion environments, ensuring economical and reliable fluid transfer.
