High-strength low-alloy steel is selected for its excellent tensile strength (≥620MPa) and impact resistance, making it ideal for high-pressure oil pipelines and ensuring long-term reliability.
Utilizing precision forging technology, the metal grain structure is denser compared to cast products, increasing strength by over 20% and eliminating defects like porosity or inclusions.
Fully automated CNC machining ensures 2-inch UNC threads comply with ISO Grade 7 standards. Each batch undergoes CMM inspection, with tolerance controlled within ±0.01mm.
Phosphating Layer: Enhances adhesion and wear resistance.
Powder Coating: Provides uniform anti-corrosion protection, withstanding ≥500 hours of salt spray testing.
The high-strength low-alloy steel selected features an excellent tensile strength of ≥620MPa, specifically designed for high-pressure environments.
Precision forging creates a denser metal grain structure, which increases the component strength by over 20% and eliminates common casting defects like porosity.
The 2-inch UNC threads are machined to ISO Grade 7 standards, ensuring high-precision, leak-proof connections for oilfield applications.
Yes, the electrostatic powder coating withstands ≥500 hours of salt spray testing, making it highly suitable for corrosive offshore conditions.
Every union undergoes rigorous pressure testing to ensure it can withstand pressures of at least 3000 psi.
We utilize automated CNC machining and CMM inspections to keep thread tolerances strictly within ±0.01mm.
