Why Choose Our Fasteners Exported to USA?

Fasteners are critical for ensuring leak-proof flanged connections, pressure containment, and safe operations in US refineries, petrochemical, chemical, and power plants. Before finalizing fasteners for export to USA, our technical team recommends evaluating four key factors:

  1. Material Grade — A193 B7 with A194 2H for standard high-temperature service. B7M/2HM for sour service (NACE MR0175). B8M Class 2 for corrosive and chloride service. B16 and A453 Gr 660 for higher-temperature service. L7M for low-temperature service. Exotic alloys for aggressive chemicals.
  2. Service Environment — Sour service requires B7M/2HM bolting with hardness limited to 22 HRC. Corrosive service requires B8M Class 2 or exotic alloys. High-temperature service requires B16 or A453 Gr 660. Low-temperature service requires L7M.
  3. Bolt Load & Joint Integrity — Bolting must be selected to provide sufficient bolt load for the gasket to seal properly. Hydrogen service requires specific bolting grades and hardness limits. Bolt stress calculations should be performed per ASME PCC-1.
  4. Thread & Dimensions — Threads must conform to ASME B1.1, Class 2A fit for studs and Class 2B for nuts. UNC for 1" and smaller, UN8 for 1-1/8" and larger. Bolting length should be selected to ensure proper engagement and gasket compression.

If you are unsure which fasteners best suit your US application, our technical team is available to review your piping specifications, process data, and project requirements — and recommend the most suitable bolting solution for the US market.
