Connector Flange: Temperature Range -20°C to 400°C

Component Specifications

Definition

The Connector Flange is a critical interface component in injection lance systems, designed to provide a leak-proof, high-pressure connection between the lance body and external piping or equipment. It features standardized bolt patterns, sealing surfaces, and alignment features to ensure proper installation and operational integrity under demanding industrial conditions.

Working Principle

The flange operates by creating a mechanical seal through compression between mating surfaces, typically using gaskets or O-rings, secured by bolts or clamps. It distributes mechanical stress evenly across the connection point while maintaining alignment and preventing fluid leakage under operational pressures and temperatures.

Materials

Typically manufactured from stainless steel (AISI 304/316), carbon steel, or alloy steels; may include surface treatments like plating, coating, or passivation for corrosion resistance.

Frequently Asked Questions

What is the primary function of a Connector Flange in an injection lance?

It provides a secure, leak-proof connection between the injection lance and external piping systems, ensuring safe fluid transfer under high pressure and temperature conditions.

How do I select the right flange material for corrosive environments?

Choose stainless steel (AISI 316) for general corrosion resistance, or specify alloys with coatings/platings for harsh chemical exposures, based on fluid compatibility and operational requirements.
