Fully Welded Ball Valves: Core Advantages
Offshore oil and gas platforms operate in one of the harshest industrial environments—constant salt spray (35,000 ppm chloride concentration), extreme pressure (up to 42 MPa), temperature fluctuations (-20°C to 150°C), and limited operational space. Valves, as critical flow control components, face unique maintenance challenges: traditional side-entry or bottom-entry ball valves require full pipeline disassembly for […]
Ball valves are ubiquitous in industrial fluid handling—from oil and gas pipelines to chemical processing—due to their fast 90° actuation, tight sealing, and durability. However, selecting between full port (FP) and reduced port (RP) designs is critical: it directly impacts flow efficiency, energy consumption, and long-term operational costs. Full port valves feature a ball bore […]
Introduction Seawater intake systems are vital for power generation (cooling), desalination (raw water), and offshore oil/gas (injection water). However, seawater’s contaminants—suspended solids (20–100 mg/L), marine organisms (barnacles, algae), and sediment—damage downstream equipment (pumps, RO membranes). Basket strainers with 316L stainless steel mesh solve this: they capture debris while resisting seawater’s 35,000 ppm chloride corrosion. This […]
In high-risk sectors like oil and gas, petrochemicals, and refining, fire safety and valve reliability are non-negotiable. API 6FA— the standard for fire-testing quarter-turn valves—sets strict criteria for valves to maintain integrity during and after fires. Fire-safe plug valves with emergency sealant injection stand out: they combine plug valves’ compact, quick-operation design […]
Different Methods of Wastewater Treatment Introduction Wastewater treatment is a critical process for environmental protection and public health, and as an Industrial Valve expert at TIANYU, I recognize the pivotal role that valves play in these systems. With increasing regulatory pressures and technological advancements, selecting the right valves for each treatment stage is not just […]
