Natural Gas Vent Stack High-altitudeAnti-corrosion: Wisson P4 Flexible Robot Showcases Exclusive "Air CurtainIsolation Technology"

No manual climbing, no scaffolding required—a single operator can now complete precise aerial painting using adrone. Recently, the anti-corrosion company under Jiangtou Gas Service and theOil & Gas Technology Research Institute applied Wisson Technology's AP30-P4Aerial Flexible Atomization Spraying System to the anti-corrosion treatment ofnatural gas vent stacks. This successfully achieved the leap from "manualhigh-altitude work" to "intelligent drone operation," solvinglong-standing challenges in safety and efficiency, and earning high recognitionfrom the client.

As critical infrastructure in natural gastransmission systems, vent stacks are constantly exposed to the elements,making regular anti-corrosion maintenance essential. Traditional manual methodsnot only require extensive scaffolding but also entail fall risks, creating atrade-off between efficiency and safety. To overcome this, the anti-corrosioncompany focused on the structural characteristics, process requirements, andoutdoor environment of vent stacks. Based on Wisson's AP30-P4 system, and aftermultiple rounds of solution optimization, equipment debugging, and simulationtests, they ultimately developed a specialized solution for vent stack paintingand anti-corrosion.

Leveraging Pliabot® flexible roboticstechnology, Wisson's AP30-P4 system demonstrated multiple significantadvantages in this application:

**Significantly Enhanced Safety:** First,fully unmanned high-altitude operations mean personnel work only on the ground,fundamentally eliminating fall risks and ensuring more reliable safety control.Second, based on the Pliabot® flexible embodied intelligence architecture—combining flexible joints with tactile AI—theAP30-P4 achieves dynamic adaptive balance during operation. Its flexiblestructure can actively dissipate energy from unexpected collisions, enablingunmanned, ultra-close, non-damaging operations and comprehensively ensuring thesafety of both the structure and the equipment.

**Comprehensive Upgrade in ProcessQuality:** Addressing the challenge of paint focusing on the vent stack'sslender, compact body, the AP30-P4 innovatively employs "Air CurtainIsolation" atomization technology. By actively guiding and constrainingthe paint flow path and配合 intelligent control forprecise regulation, it highly concentrates the paint on the target area,minimizing overspray and preventing sagging. This technological breakthroughdelivers dual improvements in quality and efficiency: the coating is uniformand dense with significantly enhanced adhesion, effectively extending equipmentservice life.

**Major Breakthrough inCost-Effectiveness:** On one hand, through the coordinated application ofintelligent path-planning algorithms and the autonomous flight spraying system,the operation time per single stack was reduced by over 20%, substantially boostingefficiency. On the other hand, it eliminated the labor and time costsassociated with scaffolding erection/dismantling and other high-altitude workphases, reduced auxiliary manpower needs, and drove an overall project costoptimization of approximately 25%.
