According to the cylinder pressure and inside diameter size, different steel tube Would be choosed.
ID ≤300mm, choose cold rolled precision seamless tube
300mm≤ID ≤500mm, choose hot rolled seamless tube
500mm≤ID ≤1000mm, choose forged tube
Steel grade : SAE1020, SAE1045, 27SiMn , S355JR, S355J2G3, St52-3, SUS304, SUS316L etc .
Inside boring and honing , roughness R0.2-R0.3
Inside chromating : if necessary ,tube inside chromating could be applied
2.Piston rod
steel grade : SAE1045, 42CrMo4, SUS410 ,SUS420, SUS304, SUS316L
Totem company ensure that every piece piston rod would be surface hardened before chromating, surface hardness is HRC55~60 , Chromating film thickness is 0.03~0.04mm if there is no other specific requirements.
3.Seal ring and O ring
According to the customers' requirements and working condition, Totem company would choose suitable
seal ring kit, seal ring brand include: Parker, Merkel, NOK, Guangzhou Rubber institute, Taiwan brand etc. Totem company would supply suitable seal solution for their customer so that hydraulic cylinder has more lifetime, easy maintenance and simple repairing.
4.Tube and flange welding
The welding on cylinder tube and flange would be Ultrasonic tested every time, the welding seam would be
cleaned before machining. Totem company ensure that every welding seam has no any leak during lifetime.
5.Assembly and pressure test
Before hydraulic cylinder is assemblied, every spare parts would be measured and cleaned. After hydraulic cylinder is assemblied, pressure test would be carried out one By one, Totem company ensure that testingpressure is higher 30%-50% than working pressure, and pressure holding time 30~60 minutes is necessary. Every piece hydraulic cylinder must be tested completely without any leak
