Expert FAQ — Tube Graphite (Terminology & Usage Guide)

Q1: What is "isostatic graphite" and why is it superior for tube graphite? Isostatic graphite is made by cold isostatic pressing, yielding extremely uniform fine grain size (<15μm), low porosity, and exceptional isotropy—crucial for structural strength and longevity in tubes subjected to high thermal stress.

Q2: How are inner diameters and wall thickness controlled during production? By high-precision CNC machining, achieving ID tolerances as tight as ±0.03mm, and wall thickness consistency crucial for fluid dynamics and pressure containment.

Q3: What are the main international standards for carbon graphite tube? Core standards: ASTM C559/C560 (density, mechanical test), ASTM C561 (electrographite properties), ISO 9001 (QA management), and FDA for food-contact/safety.

Q4: Can tube graphite be used directly for corrosive acids or gases? Yes, provided the type is high-purity (C≥99.9%) and application-specific (e.g., sealed or resin-impregnated for extreme acids); carbon graphite tubes excel for acid, alkali, and chlorinated gas lines where steel fails.

Q5: How does service life of graphite tubes compare to metal or ceramic? In aggressive settings, graphite tubes offer 2–5x longer lifespan than SS304/316, and 1.7–2.2x compared to alumina ceramics, due to their chemical inertness, thermal shock tolerance, and self-lubrication.

Q6: What’s the maximum length available for a single graphite tube? For factory direct orders, up to 3500mm (11.5 ft) in length can be achieved, with OD up to 550mm, depending on the forming and heat treatment equipment.

Q7: Are there specific installation requirements or supports for long tubes? Yes. Long or thin-wall tubes require PTFE or elastomer pads at support points, proper sleeve or bushing, and expansion chamber for thermal cycling per ANSI/ASME PTC-36 recommendations.
