Import Detector Leak Kqf1500 Steam Turbine Parts — Buy in wholesale FOB from Supplier in China

The DETECTOR LEAK KQF1500 is a hydrogen leakage detection sensor designed for steam turbine enclosures in thermal and nuclear power plants. It operates using catalytic combustion technology to identify trace hydrogen concentrations below 1% volume, with a detection range of 0.1% to 4% H2 and a response time under 10 seconds. The unit is rated for continuous operation at temperatures up to 80°C and pressures up to 1.5 MPa, with an IP65-rated enclosure for dusty and humid environments. This sensor is part of a larger turbine safety system and is typically installed in the generator housing and hydrogen cooling loops.

The sensor housing is constructed from 316L stainless steel with a sealed ceramic sensing element, and the internal circuitry uses precision thermocouples and pressure-compensated gas flow sensors. The KQF1500 model is compatible with standard 4-20 mA output signals and supports Modbus RTU over RS-485 for integration into DCS systems. While the supplier does not list formal certifications, the design aligns with IEC 60079-0 and IEC 60079-11 standards for explosive atmospheres, which are typical for hydrogen monitoring equipment in power generation. The unit is not intrinsically safe by default but can be paired with barrier isolators for Zone 1 installations.

This component is purchased by utility operators in coal-fired, nuclear, and hybrid power plants across Asia and Eastern Europe for turbine safety compliance. Buyers typically order in batches of 2 to 12 units per plant, depending on turbine size and enclosure layout. Packaging includes anti-static foam and sealed moisture-barrier bags with desiccant. Lead times are generally 6 to 10 weeks ex-warehouse in Deyang, with FOB Qingdao or CIF Singapore available upon request. Buyers must confirm compatibility with their existing control panel wiring and alarm thresholds before procurement.

Deyang Dongfang Yoyik Engineering Co., Ltd. is based in Jingyang District, Deyang, Sichuan, and operates as a specialized supplier of turbine components and power plant instrumentation. The supplier’s profile indicates active engagement in the power equipment sector with a focus on spare parts for steam and hydro turbines. The company lists technical collaboration with international brands but provides no public details on certifications, workforce size, or annual turnover. Its trust tier is classified as harbor, indicating basic verification of legal registration and address.

The supplier does not claim ISO certification, in-house testing labs, or direct manufacturing of the KQF1500 sensor. It sources, assembles, or distributes turbine-related components, including sensors, switches, and control modules. The listing includes a broad catalog of parts, suggesting distribution or system integration capabilities rather than primary manufacturing. Buyers should request documentation for the origin of the sensor’s core components and confirm whether calibration certificates are provided per unit.
