Tubes China specializes in supplying
honed tubes.
Product range:
Size: ∮20mm -500mm ID
Wall thickness: 2-50mm
Material: GRB, 27SiMn, ST52, SAE1026
Standard: GB/T8713-88, GB/T3639-2000, DIN2391,
EN10305
Honed tubes can be produced according to the demands
of costumers that the degree of precision can reach
H8/H9. Burnishing and honing service can be provided
depending on the roughness requirement of inner
diameter.
In addition, our company and Wuxi Beilai Steel Group
have established a joint venture. Therefore, we can
provide honed tubes not only with a large scale, but
also in a very short lead time.
