Carbon Steel British Thread Hollow Male Adapter BSP BSPT UNF Thread

Carbon Steel British Thread Hollow Male Adapters BSP BSPT UNF Threads

I. Product Positioning & Core Value

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 (e.g., pipeline systems, hydraulic circuits in machinery), addressing economic connection needs for British-standard interfaces.

II. Detailed Specifications

1. Material & Surface Protection

• Base Material:
  • Q235: General-purpose grade, cost-effective for low-pressure (≤80bar) and dry scenarios (e.g., agricultural machinery pipelines).
  • 45# Steel: Quenched-tempered, with tensile strength ≥600MPa, suitable for high-pressure (≤200bar) and impact-prone scenarios (e.g., hydraulic joints in construction machinery).
• Surface Treatments (core protection, determining service life):

2. Thread & Structural Design

• Thread Standards:
  • Pipe Threads:
    • BSPP (parallel, 55° thread angle, e.g., 1/2"-14 BSPP): For low-pressure water/gas (requires gaskets).
    • BSPT (tapered, 55° thread angle, e.g., 3/8"-19 BSPT): Self-sealing for medium-pressure hydraulics.
  • Fastening Thread: UNF (fine thread, 60° thread angle, e.g., 1/4"-28 UNF): For precision gas circuits (requires face seals).
• Hollow Design: The through-hole diameter matches thread specifications precisely (e.g., 1/2" thread → φ8.5mm through-hole). Roller-burnished inner walls eliminate burrs, ensuring smooth fluid flow (pressure drop ≤8%, vs. 15% for cut surfaces).

V. 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 (blue-white zinc for cost, dacromet for durability) 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 (e.g., construction/agricultural machinery) in dry/low-corrosion environments, ensuring economical and reliable fluid transfer.
