Manufacturing Process of Gas Ball Valves

Step-by-Step Process (with Key QC Points):

Material Selection: Verified carbon steel/stainless steel per ASME/ISO standards.
Casting/Forging: Valve bodies & balls are precision cast or hot-forged; crack checked via ultrasonic NDT.
CNC Machining: CNC lathes ensure micron-level tolerances on ball roundness and seat finish.
Surface Treatment: Anti-corrosion coating, fire-safe sealing, cryogenic plating as needed.
Assembly: Robotic assembly of ball, seat, stem, and housing; torque tested to API 6D.
Hydrostatic & Pneumatic Testing: 100% pressure, leakage, and sealing integrity test (ISO 5208).
Final Inspection & Packaging: Barcode traced. Compliance: API, ISO, CE, PED, SIL.

Gas Ball Valves Application Scenarios & Case Study

Case: Natural Gas Distribution in Urban Main Pipeline (DN600)

HBYS supplied 50 sets of DN600 full welded **gas ball valves** to the Hangzhou City Gas Expansion Project. The valves underwent 100% hydrostatic and low-temperature (−46°C) testing. Field data over 7 years shows:

Zero internal leakage detected
No corrosion on body/trim despite H₂S content (verified by ultrasonic thickness test)
Automated SCADA remote opening/feedback with 98.9% uptime
Energy savings: Pipeline loss reduction by 3.1% (vs. previous cast/fixed ball valve design)

Oil and gas ball valve products are essential for midstream/downstream logistics, oil tank farms, compressor stations, and LNG regasification units. Their robust mechanical integrity and high cycle life make them preferred for hazardous environments.

FAQs & Expert Answers for Oil and Gas Ball Valve Selection

Q1: What materials are best suited for gas ball valves in hydrogen sulfide service?
A: For H₂S-rich or sour gas, NACE MR0175/ISO 15156-approved stainless or alloy steels are mandatory, with anti-sulfide embrittlement treatment and PTFE/Peek seats.

Q2: How are pressure ratings determined for natural gas ball valves?
A: Pressure class is defined by process max pressure/temp per ASME/EN charts. Typical PN16/PN40 or ANSI 150/300/600 are used based on network pressure and code compliance.

Q3: What seat material should I use for high-cycle gas ball valve applications?
A: PTFE is standard for inert/non-abrasive gas. For high-cycle/abrasive duties, RPTFE, Devlon, or metal seats with chrome-plated balls excel in wear, extending service life.

Q4: What are the main international acceptance standards for oil and gas ball valve testing?
A: Major standards: API 598/ISO 5208 (leakage/pressure), API 6D (pipeline valves), API 607 (fire-safe), EN 12266, CE/PED marking.

Q5: How do I ensure proper installation alignment and avoid leakage?
A: Align the piping axially, use correct torque on bolts, verify gasket compatibility (graphite/PTFE), and perform pre-commissioning hydrotests. Always reference API 6D install guidelines.

Q6: Are custom stem extensions or actuation available for buried valves?
A: Yes. HBYS offers >=3m stem extensions, gearboxes, and integrates with most pneumatic/electric actuators including remote monitoring/diagnostics.

Q7: What aftersales support is included?
A: Standard: 3 years warranty, 24/7 tech support, rapid spare dispatch, and lifecycle valve health audits onsite or remotely.
