1. It produced with high temperature-resistant HTV, all parameters can be met in high temperature pressure.
2. Produced with high acid-resistant material and with introducing nano-metric abrasion-resistant material, corrosion free in acid medium（H2S、SO2） which elongates its lifetime.
3. Capable to make metallic processing such as turning, milling, planing, grinding, b[ring and screwing, no layer, scrap, crack may occur and with satisfactory roughness on finished surface.
4. No dimension change in diameter at temperature rise from room temperature to 240℃ with maintaining for 1 h, and longitudinal linear variation of 0.01-0.015/m, electric insulation≥500MΩ.
5. Rods ofФ40、Ф50、Ф60、Ф70、Ф80、Ф90、Ф100、Ф110、Ф127、Ф130 in diameter are available, with length dimension as required by customers.
