The 21mm Durable Camera Head Skids stand as a cornerstone in industrial-grade pipe inspection, merging robust engineering with high-precision imaging capabilities. Crafted to thrive in the most demanding environments—from gritty municipal sewers to chemical-laden industrial pipelines—these skids ensure unobstructed, smooth movement through pipe interiors while capturing detailed visuals that leave no defect unnoticed. As a vital component in modern inspection systems, they seamlessly integrate with existing setups to pinpoint critical issues such as structural cracks, stubborn blockages, and hidden corrosion, minimizing the need for invasive exploratory work.

Heavy-Duty Construction: The dual-material build—stainless steel shell for impact resistance and reinforced ABS skids for flexibility—creates a durable solution that withstands repeated collisions with debris and resists degradation from harsh chemicals, ensuring consistent performance over extended service life.
IP68 Waterproof Design: Engineered to operate flawlessly in fully submerged conditions, this camera head handles high-pressure water jets and prolonged exposure to moisture, making it indispensable for flood-prone or waterlogged pipe networks.
Adjustable Lighting: Equipped with 12 high-intensity white LEDs featuring stepless dimming control, it adapts to varying light conditions—from pitch-black sewer lines to dimly lit industrial ducts—ensuring clear visibility of even the smallest defects.
Self-Leveling Function: A built-in gyroscopic stabilizer maintains a horizontal viewing angle regardless of pipe twists or turns, eliminating the need for constant manual adjustment and reducing operator fatigue during long inspections.
Municipal Sewer Systems: Plays a key role in proactive maintenance, detecting early signs of root intrusion, joint leaks, and pipe collapse risks in underground networks, helping municipalities avoid costly emergency repairs.
Industrial Facilities: Essential for monitoring chemical transfer pipes, wastewater treatment lines, and cooling systems, where corrosion or blockages could lead to production downtime or environmental hazards.
Construction Sites: Validates the integrity of newly installed pipes during post-construction checks, ensuring compliance with building codes and preventing future operational issues in residential, commercial, and infrastructure projects.
Q: Can this camera head navigate tight bends?
A: Yes, its compact 21mm diameter and flexible skid design allow it to maneuver through 90° bends in pipes as narrow as 45mm, especially when paired with the 5.3mm fiberglass push rod for enhanced agility.
Q: How is the camera powered?
A: It connects to the inspection system’s main power supply via a rugged, waterproof cable that extends up to 50 meters, ensuring uninterrupted operation even in deep pipe networks.
Q: What is the expected lifespan of the skids?
A: With proper maintenance, the stainless steel and reinforced ABS components typically deliver a service life of 3–5 years under regular industrial use.
