Product Features:

Instrument tube is the core supporting pipe material for industrial automation control systems, specially designed for instrument sampling, signal transmission, pneumatic/hydraulic power transmission, and instrument equipment protection. It is the "industrial blood vessel" that connects detection instruments, actuators, and control systems. Its core characteristics are small diameter, high precision, high cleanliness, corrosion resistance, and strong dimensional stability, which can perfectly adapt to the fine connection and high-precision measurement needs of instrument equipment.

Instrument tube is a small-diameter seamless (or precision welded) pipe made by precision cold rolling/cold drawing process, mainly used for DCS/PLC automation control systems in industries such as petrochemicals, power, metallurgy, pharmaceuticals, semiconductors, etc. It is responsible forMedia sampling, pneumatic power transmission, instrument signal transmission, equipment protectionThe four core functions are the key basic components for achieving precise measurement and automatic control of industrial processes.

Core advantages (different from ordinary industrial pipes)

Core application scenarios

Instrument sampling pipeline: The medium sampling and connection of pressure gauges, pressure transmitters, level gauges, flow meters and other detection instruments are the most core application scenarios;

Pneumatic/hydraulic power pipelines: power medium transmission for pneumatic valves, pneumatic actuators, and hydraulic instruments;

Instrument signal protection tube: Cable protection sleeve for instruments such as thermocouples, thermistors, pressure sensors, etc., to isolate environmental interference;

Special condition instrument matching: specialized instrument pipelines for LNG low-temperature storage tanks, high-temperature and high-pressure boilers, and highly corrosive chemical equipment.
