General Technical Specifications for Self-Propelled Pipeline Inspection Robots

1 Scope

GB/T 46366-2025 is the Chinese national standard covering the robot that drives itself through a pipeline instead of being pushed by the product - the traction and the obstacle negotiation at bends and valves, the inspection sensors it carries, the power and endurance, and the recovery when it stops moving. It matters because unpiggable lines are exactly the ones nobody can inspect. First edition, already in force. Issued on 5 October 2025, it has been in force since 5 October 2025.

This document specifies the classification, model codes, technical requirements, and inspection procedures for self-propelled pipeline inspection robots (hereinafter referred to as "robots"). The rules, markings, instructions for use, packaging, transportation and storage, and the corresponding test methods are described. This document applies to robots used for internal inspection of long-distance pipelines, public pipelines, industrial pipelines, and municipal water supply and drainage pipelines.
