Product Uses & Advantage
Uses:
High-Pressure Wellhead Equipment – Connects and regulates flow between Christmas tree components in oil/gas production systems, withstanding 15,000+ psi working pressures.
Catalytic Reactor Feed Systems – Precisely controls reactant flow rates in FCC and hydrocracking units while resisting catalyst erosion.
Acid Gas Injection Lines – Provides durable connections for CO2 and H2S transport pipelines in carbon capture systems.
Advantages:
Multi-Layer Corrosion Protection – Combines alloy resistance with internal ceramic coatings for extended service in sour service environments.
Thermal Deformation Resistance – Special grain structure design maintains dimensional stability between -46°C to 650°C operating ranges.
Integral Flow Control – Precision-cast orifice plates eliminate secondary machining requirements for accurate flow restriction.
Product Application
The limit tube connector parts is a kind of petrochemical machinery. Here are some specific application scenarios of limit tube connector parts:
Deepwater Subsea Manifolds – Connects production jumpers with built-in erosion monitoring features for remote offshore fields.
Ethylene Cracker Transfer Lines – Handles 800°C+ pyrolysis gas streams with integrated thermal expansion compensation.
Sulfur Recovery Unit Piping – Special alloy versions resist wet sulfuric acid corrosion in Claus process tail gas systems.
