Import Bolt Electric Heating Rod Zj-20-T2 — Buy in wholesale FOB from Supplier in China

The Bolt electric heating rod ZJ-20-T2 is a specialised immersion heater designed for power plant auxiliary equipment, specifically for maintaining bolt temperature in turbine and generator assemblies to prevent thermal seizure during start-up and shutdown cycles. Manufactured by Deyang Dongfang Yoyik Engineering Co., Ltd. in Deyang, Sichuan Province, this rod operates as part of a broader catalogue of electromechanical spares for hydroelectric and coal-fired generator sets. The ZJ-20-T2 designation indicates a 20 mm diameter unit with T2 thermal classification, though buyers should confirm exact wattage, voltage rating, and sheath material with the supplier directly.

Constructed typically with a stainless steel sheath and magnesium oxide insulation surrounding a nickel-chromium resistance element, this heating rod must withstand cyclic thermal stress and potential vibration in rotating machinery environments. The bolt heating application requires uniform heat distribution along the immersed length to expand bolts evenly without localised overheating. Standard industry practice for such equipment includes sheath temperatures up to 400 degrees Celsius and protection ratings of at least IP55 for oil-exposed installations, though the supplier's exact certification status and material certificates should be requested before order confirmation.

Power plant maintenance teams, original equipment service providers, and turbine overhaul contractors represent the primary buyers for this component. The ZJ-20-T2 serves in both planned outages and emergency replacement scenarios where bolt removal is time-critical. Sourcing from Deyang Dongfang Yoyik Engineering positions buyers within a supply chain focused on Chinese domestic power generation infrastructure, with the supplier's ISO9002 certification history noted in their materials. Buyers should verify current certification validity, applicable voltage standards (220V/380V AC or DC variants), and whether the unit includes integral thermocouple feedback for temperature monitoring.

Deyang Dongfang Yoyik Engineering Co., Ltd. operates from Huashan Plaza in Jingyang District, Deyang, Sichuan Province, China, with postal code 618000. The company maintains a position within China's electromechanical equipment sector, specifically targeting power plant spare parts and auxiliary systems. Its trust tier is classified as harbor, with a response rate recorded at 0.00 percent and zero average response hours, indicating no verified engagement data is available through the platform. Buyers should initiate direct contact to assess current responsiveness and active trading status.

The supplier's product range spans hydroelectric and coal-fired generator set accessories, electrical and electronic product processing, and sensor technologies including magnetic pickups, LVDT displacement sensors, pressure switches, and eddy current sensors. The company references ISO9002 quality system certification in its materials, though buyers must independently verify current certification scope, validity dates, and accreditation body. No verified client list, annual revenue, employee count, or factory audit information is provided in the source data, and any such claims should be treated as unconfirmed until documentation is received directly from the supplier.
