- Our special features of alloy tube -

1. From thin to ultra-thick pipes, a variety of steel alloy tubes can be created. 
2. Core drawing of ultra-thick pipes can be made according to thickness (t)/outer diameter(D) X 100=36%. 
3. Processing cost is superior to cutting a round pipe and then using a gun drill to machine the inner surface in order to make multiple types of finishes. 

We provide you the ultrasonic defect tests in the deep.

- The range of available alloy steel standards -

1. Steel alloy pipes for use in plumbing (STPA12~STPA25) 
2. Steel alloy pipes for use in boilers and heat transfer devices (STBA12~STBA25) 
3. Nickel-Steel alloy pipe for low-temperature use (STPL380, STPL450, STBL380, STBL450) 
4. Steel pipe for various testing drilling purposes (boring rod, etc.) 
5. Various automotive parts, mission turbine shaft (SCR440H), piston pin (SCM415), etc.
