Main features of Pennchem® CT

Tubes with excellent bend radius that enables flexible piping

Processing of corrugated part

Corrugated parts can be contracted up to around 50% or elongated to around 140%. The bend radius is small (about 1/4 of its inside diameter) with almost no change in inside diameter when bent. The piping flexibility is more excellent than the convoluted tubing.

Fluids inside are easily visible

Transparency is high and fluids inside are easily visible.

Material : Fluoropolymer PFA
Working temperature : 150℃

Temparature and depressurazation for burst

• 上のグラフはペンケム®CTおよびペンケム®TXの破裂圧力と温度との関係を示したものです。
  例）ペンケム®CT1/2"の100℃の破裂圧力は？
  　　0.96MPa×0.58=0.56MPa
• 安全圧力は通常使用温度における破裂圧力の1/3～1/5で設計されます。
• ペンケム®CTおよびペンケム®TXの使用を検討される場合は衝撃の有無、流体の危険性、継手の形式等の使用条件を考慮して設計してください。
• ペンケム®CTおよびペンケム®TXをご利用の際は使用性、安全性等を事前に試験等でご確認の上ご使用ください。

1. Intertwine the tube and it does not make damage
2. Calculating formula is D=Rx2.
3. At the room-temp
4. Don't bend tubes more than bending limit.
