Small Diameter Bright Annealed Tube / Pipe

Designed for critical and purity applications such as semiconductor manufacturing, Ding Ten's high purity tubing delivery of gases, chemicals and solvents, or use in ultra High vacuum piping for reducing out gas rate.



From advanced manufacturing processes, including special cold drawing and cold forged not just precision for sizes, but also enhance material substrutes density by cold forged process. The ID is cold drawing to a 15 Ra(0.4µm) finished, by Hydrogen bright annealed process removed tube lubrication and optimum anti-corrosion ability, stress free, good mechanical properties follow by precision cleaning process to removed any residual contaminants, simulated natural light inspection at both ends verifies cleaning before the tubes are nitrogen purged and capped.

半無縫管用於取代傳統有縫及無縫拋光管, 以精密溶接焊接管加以冷鍛(cold forged), 抽拉延伸, 光輝熱處理, 無塵室超純水清洗後的半無縫管其焊道金相組織, 機械強度特性和母材(coil)相同, 達到無縫管等級, 若鍛壓比夠其品質可超越一般無縫管.



傳統溶接管的焊道金相呈現鑄造樹枝狀晶, 藉由本公司BA 冷鍛管材專利製程專利加以冷鍛出優質鍛造管, 整支管子重從內到外, 從RA 到材質密度(金相組織)超越半導體廠和生技製藥產業需求.
