Why Our ASME B16.11 Half Couplings Stand Out?

1. Space-Saving Design

The single-end connection minimizes installation space, ideal for retrofitting existing systems without full disassembly.

2. Dual Connection Options

Choose between Socket Weld (for vibration resistance) or Threaded (for easy maintenance) based on your needs.

3. Extreme Pressure Resilience

Tested up to 9000LB, our couplings handle hydraulic shocks and pressure spikes in drilling and refining operations.

4. Material Versatility

Opt for carbon steel (A105) in general use, stainless steel (F304/316) for corrosion resistance, or high-yield steel (A694 F65) for sour gas environments.

5. Global Compliance

Backed by ASME, ISO 9001, PED, and NACE certifications to meet regional requirements in the EU, Middle East, and Asia-Pacific.

Applications

  • Oil & Gas: High-pressure pipelines, wellhead controls, and instrumentation.
  • Petrochemical: Corrosion-resistant connections in refining and chemical processing.
  • Power Generation: Steam lines and hydraulic systems in turbines.
  • Industrial: Compact gauge and valve installations.

FAQs

Q: Can you provide the products for sour gas applications?

A: Yes! Our NACE MR0175-compliant couplings resist hydrogen embrittlement in H₂S environments.

Q: Do you offer galvanized coatings?

A: Absolutely. Specify your surface treatment (black oxide, galvanized, etc.) during ordering.

Q: What’s included in your certification package?

A: We provide ASME compliance certificates, material test reports, and pressure test logs.

Q: How do you ensure thread accuracy?

A: Our CNC-machined threads undergo 3D scanning to meet ASME B1.20.1 standards.
