ADVANTAGES OF OUR HONED TUBE

High-precision tolerance: honed pipe, inner diameter roughness 02-0.4um, straightness maximum 0.5/1000, strict tolerance DIN2391 H8. Maximum ellipticity. 1/2 inside diameter tolerance.

Tube, inner diameter roughness less than 0.2um, straightness maximum 0.2/1000, strict tolerance DIN2391 H8. Maximum ellipticity. 1/2 inside diameter tolerance.

2. High-quality raw materials: Our raw materials mainly come from some famous steel mills, such as TPCO, Baosteel, Shagang, which are the best and largest raw material manufacturers in China.

3. High pressure resistance: the selection of better seamless tube raw materials, after cold drawing, the columnar crystal is refined into a fibrous crystal, and the work hardening is significant, and the material is more uniform.

This allows our honing tubes to work stably under higher pressures, making our honing tubes more reliable for the manufacture of hydraulic cylinders.

4. High surface perfection: The maximum inner diameter roughness of our honed tubes is Ra0.4.

5. High welding performance: The selection of excellent weldability materials and strict heat treatment process make our honing pipe have better weldability, which is of great help to the manufacture of hydraulic cylinders.

6. Strict quality control: control the entire production process, 100% inspection of each product in each process.

The company has a full set of production process equipment, cold drawing machine, honing machine, planing roll polishing machine, straightening machine, polishing machine, heat treatment furnace, grinder and so on.

There are professional technicians to carry out regular maintenance on these machines to ensure the normal work of the machine.

We have a professional internal QC team and equipment, before the delivery of chemical composition test, mechanical properties test, size test, roughness test, chromium plating layer test and other necessary inspection.

7. Better after-sales service: Any quality problems after delivery, the products with problems will be returned. We have confidence in our products and never compromise on materials and quality.
