Introduction to 3-4 HBPV LH Left-Hand Thread Ring Gauges

The 3-4 HBPV LH thread ring gauge is a specialized tool designed for inspecting high-pressure valve (BPV) threads in the petroleum and gas industry. These gauges are critical for ensuring the integrity of threaded connections in environments requiring robust sealing and durability. Below, we delve into the features, standards, applications, and common specifications of HBPV thread gauges, along with the capabilities of Sowant Precision Gage in supplying high-quality gauges.

Key Features of HBPV Thread Gauges

1. Thread Design:

   • HBPV (High Back Pressure Valve) threads are left-hand (LH) and typically feature 4 threads per inch (TPI) for larger diameters, ensuring tight sealing in high-pressure systems.

   • The gauges are divided into "Go" and "No-Go" ends to verify maximum and minimum thread limits, ensuring compliance with dimensional tolerances.

2. Material and Durability:

   • Constructed from high-grade materials like O1 tool steel, HBPV gauges resist wear and corrosion, making them suitable for harsh industrial environments.

3. API Compliance:

   • HBPV threads adhere to API 6A standards, which govern specifications for wellhead and valve equipment in the petroleum industry.

Standards and Applications

• API 6A Compliance:
  HBPV thread gauges are standardized under API 6A for inspecting threads on valves, tubing, and casing components. These threads are essential for maintaining pressure integrity in oilfield equipment, such as blowout preventers and Christmas trees.

• Primary Applications:

  • Inspection of H-type back-pressure valves and tubing hangers.

  • Quality control in manufacturing and maintenance of petroleum drilling equipment.

Common Specifications and Models

HBPV thread gauges are available in a range of sizes, with left-hand threading being predominant. Notable specifications include:

1. 2"-4 HBPV LH: A standard size for mid-range tubing connections.

2. 2 1/2"-4 HBPV LH: Widely used in high-pressure valve assemblies.

3. 3"-4 HBPV LH: Suitable for larger-diameter piping systems.

4. 4"-4 HBPV LH: Designed for heavy-duty applications in oilfield machinery.

Additional variants extend from 1-1/4” to 6-5/16”, accommodating diverse industrial needs.
