Component Specifications

Definition
The Main Body Tube is the primary cylindrical structural component of an injection lance, designed to withstand high-pressure fluid flow and provide a stable conduit for precise material injection in industrial processes. It serves as the central housing that connects various lance components while maintaining structural integrity under operational stresses.
Working Principle
Functions as a pressure vessel and flow conduit, maintaining laminar flow characteristics while withstanding internal pressure from injected materials and external mechanical stresses during operation. The tube's geometry and material properties ensure minimal pressure drop and consistent flow distribution.
Materials
Typically manufactured from stainless steel (AISI 316L, 304), carbon steel (ASTM A106 Grade B), or specialized alloys (Inconel, Hastelloy) depending on corrosion resistance and temperature requirements. Wall thickness ranges from 3-12mm based on pressure ratings.
Technical Parameters
  • Length 500-3000mm
  • Diameter 25-150mm
  • Surface Finish Ra 0.8-3.2μm
  • Pressure Rating 10-100 bar
  • Temperature Range -20°C to 400°C
  • Straightness Tolerance 0.5mm/m
Standards
ISO 1127, DIN 2448, ASME B36.10M

Frequently Asked Questions

What are the key considerations when selecting a Main Body Tube?

Material compatibility with injected substances, pressure rating requirements, temperature range, corrosion resistance needs, and connection compatibility with other lance components.

How does wall thickness affect Main Body Tube performance?

Thicker walls increase pressure capacity and structural rigidity but add weight and cost. Thinner walls reduce weight but may require pressure derating and careful handling.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
