Casing is usually installed in rigs to prevent the breakdown of the oil well and the wall. It can also prevent foreign
matters from entering to extraction process e.g., water or soil. 125 Q125-1
Tubing transports the oil and gas from well to the on ground floor.
Since ILJIN Steel has produced and supplied high value products for industry sectors in extreme temperatures and
pressures, we are building our reputations as a seamless pipe manufacturer in the industry.

Line Pipes require high yield strength, corrosion resistance and low temperature strength. ILJIN Steel offers X70 and X80 and their
corrosion resistance is ensured by conducting Hydrogen Induced Cracking (HIC) test and Sulfide Stress Corrosion Cracking (SSCC)
test. Additionally, ILJIN’s line pipes possess excellent low temperature strength which is proven by Crack Tip Opening Displacement
(CTOD) test.

Automotive-MR Damper Automotive-Upset Drive Shaft

Product Overview Product Overview

The MR damper is a computer-controlled suspension system that provides the best driving performance under any circumstances. MR A drive shaft is a mechanical component for transmitting torque and rotation, usually used to connect other components of a drive train that
dampers contain MR (Magneto Rheological) liquids, which vary in viscosity when exposed to magnetic fields, resulting in varying damping cannot be connected directly because of distance or the need to allow for relative movement between them. As torque carriers, drive shafts
and magnitude of force. Height sensors detect bumps, portholes or obstacles and adjust magnetic energy within milliseconds to provide are subject to torsion and shear stress, equivalent to the difference between the input torque and the load. They must therefore be strong
optimum damping for both comfort and control. enough to bear the stress, whilst avoiding too much additional weight as that would in turn increase their inertia. To allow for variations in
the alignment and distance between the driving and driven components, drive shafts frequently incorporate one or more universal joints,
jaw couplings, or rag joints, and sometimes a splined joint or prismatic joint.
