ADVANTAGES OF OUR HONED TUBE
1. High precision tolerances: Honed Tube, ID roughness 02-0.4 um, straightness max 0.5/1000, strict tolerance DIN2391 H8. Ovality max. 1/2 ID tolerance.
Skived & Roller Burnished Tube, ID roughness under 0.2 um, straightness max 0.2/1000, strict tolerance DIN2391 H8. Ovality max. 1/2 ID tolerance.
2. High quality raw material: Our raw material mainly from some famous steel mills, such as TPCO, BAO STEEL, SHA STEEL, which are best and largest raw material manufacturer in China.
3. High pressure resistance: Choose better raw material seamless tube, after cold drawn the columnar crystals fined to fibrous crystals, which resulted in remarkable work hardening and more uniform material.
That make our honed tubing could working stable in higher pressure, our honed tube more reliable for hydraulic cylinder manufacturing.
4. High surface perfection: ID Roughness of our honed pipe is Max Ra0.4.
5. High welding performance: Better weldablility material choose, Strict heat treatment process make our honed tubing with better weldability, It's much helpful for make hydraulic cylinder.
6. Strict Quality control: Full production flow under control and 100% inspection for each product in each processing.
>Whole production process equipment owned, cold drawing machine, honing machine, skiving & roller burnishing machine, straightening machine, polishing machine, heat treatment furnace, grinding machine, etc.
There are professional technicians do regular scheduled maintenance on these machines to guarantee them work well.
>We have professional internal QC team and equipment, Chemical Composition Test, Mechanical Property Test, Dimension Inspect, Roughness Test, Chrome Layer Test and other necessary inspection will be do before delivery.
6. Better after sales service: Any quality problem come after delivery, issue items will be resupply or refund. We have confidence in our products and never compromise in material or quality.
