This series of nickel alloy seamless pipes and capillary tubes is engineered for demanding environments requiring extreme corrosion resistance, stable performance under high temperatures, and long-term material reliability. Manufactured with advanced cold-drawing and cold-rolling processes, these tubes offer exceptional structural integrity and surface precision, making them suitable for chemical processing, offshore engineering, energy systems, aerospace applications, semiconductor equipment, and precision medical devices.
Nickel-based alloy seamless tubes and precision capillary pipes are designed for industries where materials must withstand aggressive chemicals, high thermal loads, and demanding mechanical conditions. Using premium nickel alloy billets, the tubes are processed through high-precision cold rolling and cold drawing, resulting in exceptional dimensional stability and excellent inner surface cleanliness.
These materials—including Inconel, Hastelloy, Monel, and pure nickel—are widely recognized for their superior corrosion resistance in acid, chloride, and seawater media. All tubing undergoes strict inspections under an ISO 9001 quality management system and complies with ASTM, ASME, and international marine classification standards.
The product line supports custom wall thickness, non-standard sizes, ultra-thin capillaries, and specialty grades for specific project needs.
