Component Specifications

Definition
Connection nozzles are specialized fittings designed to create leak-proof, high-pressure connections between heating jackets/coils and process piping systems. These components feature threaded, flanged, or welded interfaces that ensure proper alignment and secure attachment while maintaining thermal efficiency and structural integrity under varying temperature and pressure conditions.
Working Principle
Connection nozzles operate by providing a sealed interface between heating elements and fluid transfer systems. They maintain pressure integrity through precision machining and proper gasket/seal selection, while their material composition and design minimize thermal expansion mismatches and prevent fluid leakage during thermal cycling.
Materials
Stainless steel (304/316L), carbon steel, alloy steel, brass, or specialized alloys depending on application requirements; typically rated for temperatures up to 400°C and pressures up to 100 bar.
Technical Parameters
  • Size Range DN15 to DN150 (1/2" to 6")
  • Surface Finish Ra ≤ 3.2 μm
  • Connection Type Threaded (NPT, BSP), Flanged (ANSI, DIN), Welded
  • Pressure Rating Up to 100 bar
  • Temperature Range -40°C to 400°C
  • Corrosion Resistance Minimum PREN 25 for stainless variants
Standards
ISO 4144, DIN 11851, ASME B16.5, ISO 7005

Frequently Asked Questions

What are the main types of connection nozzles for heating jackets?

The three primary types are threaded connections (NPT/BSP for smaller systems), flanged connections (ANSI/DIN for high-pressure applications), and welded connections (for permanent installations requiring maximum integrity).

How do I select the right material for connection nozzles?

Material selection depends on process fluid compatibility, temperature requirements, and corrosion resistance needs. Stainless steel 316L is standard for chemical applications, while carbon steel suits non-corrosive environments, and specialized alloys handle extreme conditions.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
