Micro ID Thick Wall Seamless Tube

• Overview

  Micro ID thick wall seamless tube is a small caliber non-standard tube. It is generally made by finishing rolling, fine drawing or other special processes, with distinctive features of high bearing capacity and high strength, suitable for gas transmision, oil transmission or other special purposes which usually have high internal pressure and high strength.

• Application

  1. Hydraulic power systems, such as high pressure oil lines for heavy trucks

  2. Pneumatic power system

  3. High pressure fuel injection tubing for diesel engine and fuel injection pump tests

  4. High pressure pipes for automobiles

  5. The strength of pipes is very demanding in automobile manufacturing. Micro ID thick wall seamless tubes are often used in automobile exhaust system, intake system, brake tubing, joints, conveying cooling system, ignition system, fuel injection system, air conditioning system, sensor probe, pressure pipeline, high pressure oil rail pipeline, etc. Its working pressure can reach up to 300Mpa, and it can improve engine fuel efficiency.

  6. Automobile and motorcycle accessories

  7. Precision machinery

  8. Other fields which have high requirements on precision, finish, cleanliness, pressure resistance and mechanical properties of tubes.
