Expert FAQ: Technical and Operational Details
Q1. What is a “Trim” in choke valves, and why is it critical?
Trim refers to internal valve parts exposed to flow—seat, stem, and plug/disc. High-quality trims (e.g., tungsten carbide, ceramic) withstand abrasive, high-velocity particles, directly affecting service life and leakage class.
Q2. Which international standards do choke valves comply with?
Reputable products will carry API 6A/6D, ISO 10423, ANSI B16.34, CE PED, and often NACE MR0175 certification (for sour service).
Q3. What materials are used for 2 adjustable choke valves in harsh environments?
Super Duplex Stainless Steel (UNS S32750/S32760), Inconel 625/825, with HVOF or tungsten carbide-coated trims. These materials meet demands of high chloride, CO2/H2S, and erosive slurries.
Q4. What is the expected service life of premium choke valves?
Standard is 8–18 years, depending on process severity, media, and maintenance. Field proof: Globe valves in Middle East gas plants surpassed 13-year operation without major overhaul.
Q5. How is performance testing carried out?
API/ISO hydrostatic pressure testing (typically 1.5× working pressure), seat leakage per FCI 70-2, and cycle tests (typically 10,000+ cycles) are mandatory prior to shipment.
Q6. What are installation best practices for choke valves?
Install according to piping class (ANSI/ASME), align flow direction per arrow, ensure correct actuator torque, and verify flange ratings. Always validate with post-install seat leak test (ISO 5208).
Q7. What is meant by fugitive emission compliance?
Compliance to ISO 15848-1/2 ensures choke valves limit VOC (volatile organic compound) leaks—essential for environmental/safety approval.
