API Standard Flexible Graphite Sealing Material

Products Description
 

API - Compliant Flexible Graphite Sealing Solutions

Product Overview

API - Specific Performance Features

1. Extreme Pressure & Temperature Resistance
   • Complies with API 6A (wellhead equipment) requirements, withstanding pressures up to 10,000 PSI and temperatures ranging from cryogenic (-200°C) to 3,000°C.
   • Demonstrates <5% creep relaxation under sustained load at 150°C/API RP 521 recommended conditions.
2. Chemical Compatibility
   • Meets NACE MR0175/ISO 15156 for sour gas environments, resisting sulfide stress cracking in H₂S - containing media.
   • Tested to API 607 fire resistance standards, maintaining integrity during hydrocarbon fires (ASTM E162 radiant panel test).
3. Mechanical Reliability
   • Compressive strength of 60 MPa ensures structural stability in API 6D pipeline valves.
   • Self - lubricating properties reduce torque requirements in API 602 compact gate valves.

Applications in API - Regulated Industries

1. Oil & Gas Sealing
   • Used in API 6A wellhead gaskets, providing reliable seals in high - pressure/high - temperature (HPHT) drilling operations.
   • Composite versions with stainless steel inserts meet API 17D for subsea equipment.
2. Refinery & Petrochemical
   • API 600 gate valve seals resist aggressive chemicals (e.g., sulfuric acid, hydrocarbons).
   • Flame - resistant gaskets comply with API 521 泄压 device standards.
3. Power Generation
   • API 610 centrifugal pump seals maintain leak - free performance in boiler feedwater systems.
   • Graphite - metal hybrid designs meet API 617 axial compressor requirements.
