Material: ST52, E355, STKM13C, C20, CK45, 4140, 42CrMo, Stainless Steel 304, 316, 

Delivery Condition: BK, BK+S, GBK, NBK

ID Size : 20mm – 1500mm

Length: max 16m

Type: Seamless, Hot Rolled, Cold Rolled, Cold Drawn

Straightness: ≤ 0.5/1000

Roughness: 0.2-0.4 um

Standard: DIN2391, EN10305.

ID Tolerance: H7,H8,H9

Protection: Anti-rust oil on inside and outside surface, plastic caps in both ends.



1. High precision tolerance: honing tube, inner diameter roughness of 02- 0.4um, maximum straightness of 0.5/1000, strict tolerance DIN2391H8. The ellipticity is the largest. 1/2 ID tolerance.

Roller polished tube, inner diameter roughness below 0.2um, straightness up to 0.2/1000, strict tolerance DIN2391 H8. The ellipticity is the largest. 1/2 ID tolerance.

2. High quality raw materials: Our raw materials mainly come from some famous steel plants, 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 will be refined into columnar crystal fiber crystal, work hardening effect is remarkable, the material is more uniform.

So that our honing tubes can work stably under higher pressure, making our honing tubes more reliable for the manufacturing of hydraulic cylinders.

4. High surface perfection: the highest inner diameter roughness of our honing tube is Ra0.4.

5. High welding performance: the selection of better weldability materials, strict heat treatment process, so that the honed tubing has better weldability, is of great help to the manufacturing of hydraulic cylinders.

6. Strict quality control: fully control the production process, and conduct 100% inspection on each product in each processing process.

Production process is fully equipped, cold drawing machine, honing machine, rolling polishing machine, straightening machine, polishing machine, heat treatment furnace, grinding machine, etc.

These machines are regularly maintained by professional technicians to ensure that they work well.

We have a professional internal QC team and equipment to carry out chemical composition test, mechanical property test, size test, roughness test, chrome plating layer test and other necessary tests before delivery.

6. Better after-sales service: if there is any quality problem after shipment, the shipped items will be re-supplied or refunded. We are confident in our products and never compromise on materials and quality.
