Vertical pipe section for condensate drainage in steam systems

Component Specifications

Definition
A vertical pipe segment specifically designed for drip legs or condensate traps in industrial steam systems, engineered to facilitate gravitational flow of condensate away from steam lines while maintaining system pressure integrity and preventing water hammer.
Working Principle
Operates on gravitational separation principles where condensate droplets, being denser than steam, fall vertically downward through this section into the trap body. The vertical orientation minimizes turbulence, allows proper drainage velocity (typically 0.3-1 m/s), and creates a liquid seal that prevents steam bypass while enabling continuous condensate removal.
Materials
Carbon steel ASTM A106 Grade B (standard), stainless steel 304/316 for corrosive environments, with schedule 40 or 80 pipe thickness. Internal surfaces may have electropolished finish (Ra ≤ 0.8 μm) for high-purity applications.
Technical Parameters
  • Length 300-1200 mm
  • Surface Finish N5-N7 per ISO 1302
  • Connection Type Flanged (ASME B16.5) or threaded (NPT/BSP)
  • Pressure Rating PN16-PN40
  • Nominal Diameter DN25-DN150
  • Temperature Range -20°C to 250°C
Standards
ISO 1127, DIN 2448, ASME B36.10M

Frequently Asked Questions

Why must the pipe section be strictly vertical?

Vertical orientation ensures proper gravitational flow of condensate, prevents steam locking, maintains drainage velocity within optimal ranges, and eliminates pockets where condensate could accumulate and cause water hammer.

What happens if this section is installed at an angle?

Angled installation reduces drainage efficiency, may cause incomplete condensate removal, increases risk of steam carryover, and can lead to premature trap failure and water hammer incidents.

How is length determined for specific applications?

Length is calculated based on steam pressure, condensate load, pipe diameter, and required drainage velocity—typically 10-12 times pipe diameter minimum to ensure proper liquid seal formation.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
