Lance Ports: Temperature Range -20°C to 400°C

Component Specifications

Definition

Lance ports are engineered access points integrated into the structure of reaction vessels, typically featuring reinforced flanges, sealing mechanisms, and standardized connections to accommodate various types of lances. These ports enable precise introduction of reactants, catalysts, or process media while maintaining vessel integrity under high pressure and temperature conditions.

Working Principle

Lance ports operate by providing a sealed, controlled pathway through the vessel wall. When a lance is inserted, mechanical seals or gaskets prevent leakage, while the port's design allows for lance positioning, retraction, and sometimes rotation. During operation, reactants flow through the lance into the vessel, with the port maintaining pressure containment and preventing contamination.

Materials

Stainless steel (316L, 304), Hastelloy, Inconel, or carbon steel with internal linings; Seals: PTFE, Viton, or graphite; Flanges: Forged steel with ASME/EN standards

Frequently Asked Questions

What is the primary function of a lance port in a reaction vessel?

The primary function is to provide a sealed entry point for lances to inject gases, liquids, or solid materials into the vessel while maintaining pressure and preventing leaks.

How do you select the right material for a lance port?

Material selection depends on the chemical compatibility with process media, temperature, pressure requirements, and corrosion resistance needs—common choices include stainless steel for general use or specialized alloys for aggressive chemicals.
