Rocket precision tubes serve as the critical “vascular system” for propellant delivery, pressurization control and thermal management inside launch vehicles. Even micro-scale contaminants such as welding slag, metal chips, oxide scale and residual oil trapped inside tube walls may cause valve jamming or nozzle blockage, posing fatal risks to rocket engine and servo-valve safety. Traditional chemical pickling and liquid flushing struggle to meet aerospace ultra-high cleanliness requirements for complex bent tubes and multi-joint assemblies.

The APS AM‑2 pneumatic tube cleaning gun provides a reliable dry physical cleaning solution for aerospace precision pipeline pre-commissioning. As core tube cleaning equipment, the AM‑2 launcher uses compressed air to propel custom foam projectiles, also known as foam pigs, through the full length of tubes. The oversized high-density foam projectile creates tight interference contact with the inner wall, scrubbing and carrying away stubborn contaminants while smoothly passing through elbows, tees and fittings.

Compared with wet cleaning processes, the AM‑2 system leaves no residual liquid inside aerospace tubes and avoids secondary contamination. It supports rapid cleaning for stainless steel precision tubes, hydraulic tubes and fuel pipelines with flexible size adaptors. Built-in pressure safety mechanisms ensure stable and controllable operation in aerospace clean workshops.

Aerospace manufacturing demands traceable, repeatable cleanliness verification. The AM‑2 tube cleaning system helps aerospace manufacturers achieve consistent inner-wall cleanliness, reduce reject rates and satisfy strict acceptance standards for rocket propulsion and hydraulic systems. Widely validated in aerospace, marine and rail sectors, this pneumatic projectile cleaning technology has become a preferred process for precision pipeline pre-commissioning cleaning.

APS delivers complete pneumatic tube cleaning packages including the AM‑2 launcher, matched foam projectiles, adaptors and recovery devices to support one-stop pipeline cleanliness assurance for high-end manufacturing.
