What High-Velocity Flushing Achieves

Turbulent flow flushing creates the velocity and scrubbing action needed to mobilize and remove construction debris that low-flow rinsing leaves behind.

Protect Sensitive Equipment

Prevent pump impeller damage, valve seat scoring, and microchannel blockage. One debris particle can cause thousands in equipment repairs.

Remove Construction Debris

Eliminate weld slag, metal shavings, gasket fragments, PTFE tape, and fabrication residues that accumulate during construction.

Verified Cleanliness

Progressive filtration with documented filter inspections proves your system meets cleanliness specifications before startup.

Faster Commissioning

Complete debris removal in days, not weeks. Our mobile skids and experienced team keep your project on schedule.

Complete Documentation

Detailed turnover packages including flow records, filter inspection photos, conductivity logs, and compliance certificates.

Owner-Led Execution

Why CXP

The CXP Difference

Not all flushing services are equal. Here's what sets professional high-velocity flushing apart.

Basic Low-Flow Rinse
  • Insufficient velocity to mobilize heavy debris
  • Debris settles back after flushing stops
  • No verification of cleanliness levels
  • Generic approach ignores system geometry
  • Equipment damage discovered at startup
CXP High-Velocity Flushing
  • 5+ ft/s turbulent flow mobilizes all debris
  • Progressive filtration captures contaminants
  • Documented filter inspections prove results
  • Branch-by-branch methodology for complete coverage
  • Protected equipment, clean commissioning

Construction Debris Types

Click each debris type to learn about sources, characteristics, and removal requirements.

🔥 Weld Slag & Spatter

The most dangerous debris type. Hard, angular particles from welding operations can score valve seats, damage pump impellers, and block microchannels. Found near every weld joint in new construction.

⚙️ Metal Shavings & Swarf

Sharp, curled chips from cutting, drilling, and threading operations. Can wrap around pump impellers, lodge in valve seats, and cause seal failures. Often coated with cutting oils.

📦 Gasket Fragments & PTFE

Punch-out circles, fiber shreds, and tape fragments from flange assembly. Flexible materials can wrap around impellers and block small passages. PTFE tape is especially problematic.

🌡️ Heat Tint & Oxide Scale

Thin, flaky oxide layers from welding heat-affected zones. Brittle scale breaks loose during operation and contaminates the system. Indicates compromised passive layer requiring passivation.

FAQ

Frequently Asked Questions

Common questions about high-velocity flushing services.

What flow velocity is required for effective debris removal?

A minimum of 5 ft/s (1.5 m/s) is typically required to mobilize construction debris. Heavier particles like weld slag may require 7+ ft/s. We calculate specific requirements based on pipe diameter, debris type, and system geometry. Our flow rate calculator can help estimate requirements.

How do you verify the system is clean?

We use progressive filtration, typically starting at 100 micron and stepping down to final targets (often 5-25 micron depending on specification). Each filter is inspected and photographed. Flushing continues until filters pass clean for the specified duration. All filter inspection photos are included in turnover documentation.

What's the difference between flushing and passivation?

High-velocity flushing removes physical debris (weld slag, metal shavings, construction contamination). Passivation is a chemical process that restores the chromium oxide protective layer on stainless steel. Most new construction projects need both: flushing first to remove debris, then passivation to optimize corrosion resistance.

How long does high-velocity flushing take?

Duration depends on system size, complexity, and initial contamination level. A typical process loop might take 1-2 days. Larger systems with many branches may require a week or more. We work with your schedule to minimize commissioning delays. Contact us with your P&IDs for an accurate timeline estimate.

What industries require high-velocity flushing?

Any industry with sensitive equipment downstream of new piping benefits from HV flushing. This includes data centers (protecting CDUs and cold plates), pharmaceutical (WFI and process systems), EV battery manufacturing, and industrial facilities with precision pumps, valves, or heat exchangers.

Do you provide documentation for turnover packages?

Yes. Every project receives comprehensive documentation including: P&ID markups showing flush paths, flow rate records, filter inspection photos, conductivity/pH logs, time-stamped progress photos, and final cleanliness certificates. Our documentation meets requirements for ASTM A380 compliance and owner/CM turnover.
