St52 Hydraulic Steel Tubes Introduction
Honed Tubes are presicion tubes with smooth inside, they also could be skived and burnished pipe. Tubes or pipes inside tolerance could be H10, H9 or H8. Outside tolerance, wall thickness tolerance are produced according to seamless cold drawn tubes for precision application standard GB/T3639-2009,EN10305 or DIN2391 standard. Material SAE1020, 20#, ST45, CK45, ST52, E355 tubes and so on for you to choose.

After-sales service:
1. Where to buy our products for one year warranty and life long maintenance.
2. 24-hour telephone service.
3. A large stock of components and parts, easily-worn parts.
Production process
Raw material – annealing for material of 45#, 27SiMn, 25Mn – Acid cleaning – parkerizing & Saponifying – cold drawn – leveling – saw off bad section – stress relieving – leveling –honing or skiving – inspection – oiled plated - packing
Quality control
1. We only buy raw material from famous tube factory, and Checking raw material quality before production.
2. We check the tube ID tolerance, OD tolerance and surface after cold drawn one by one.
3. We inspect the honed tube inside tolerance and surface again one by one after honing or skiving.
Our company has established its strategic development goal of 'creating the first brand of St52 E355 Cold Drawn Seamless Carbon Steel Tube Ready to Hone for Hydraulic Cylinder Barrel'.
