FAQ
Q: What is the maximum length graphite rod you can supply?
A: Standard extruded graphite rods are available up to 3000mm length. Isostatic graphite rods are typically available up to 2000mm. For longer lengths, we can provide joined sections or recommend alternative configurations.
Q: Can you machine threads and holes on graphite rods?
A: Yes, we offer full machining services including external and internal threads, drilled holes, grooves, and end fittings. Please provide your drawings, and we will produce finished graphite rods ready for your furnace assembly.
Q: What grade of graphite do you recommend for heating elements?
A: For heating element applications, we recommend grades with low and consistent electrical resistivity for uniform heating. Our technical team can help you select the optimal grade based on your furnace voltage, current, and operating temperature requirements.
