Aerospace Equipment

Aerospace tube is a form of seamless steel pipe higher strength and thick retaining wall. It is widely applied in aerospace equipment. There are unique grades of pipes. 10#, 20#, 35# and 45# types are general ink cartridges. 27SiMn, 12Cr1MoV, 10CrMo910, 15CrMo, 35CrMo grades of pipes are alloy steel pipes. 16Mn aerospace tube, different from general steel pipe and alloy steel tube, known as low alloy seamless steel pipe.

  • EOI aerospace tubes are featured with small volume, light weight and small power dissipation. It can perform in poor conditions featuring high efficiency, high reliability and long service lifestyles.
  • We configure advanced thermal treatment equipment with small temperature difference inside the furnace to ensure stable heating temperature. Certainly provide rotating air conditioning for this seamless steel pipe certain that water quenching of steel pipe cools uniformly. Two Siemens electronic control six roll straightening machines ensure the straightness of aerospace tubes after heat treatment.


  • May characterized by high strength, uniform and stable structure and satisfaction. This seamless steel pipe uses pure steel (P ≤ 0.020%, S ≤ 0.010%).
  • JST aerospace tube features high wall thickness precision and small tolerance range. The unevenness of precisely the same section is mean or less than 9.5%.
  • The control precision of warmth treatment furnace is actually equal to or less than 5℃.
  • This seamless steel pipe has low residual press. After heat treatment and warm tempering, we adopt hot straightening. Extinguish straightening is actually controlled end up being equal to or close to 450℃.
