Portion I: Product INTRODUCTION
one. Description: Honed tube is a kind of smooth bore steel tube utilized to manufacture hydraulic cylinder barrels that is the main portion of a piece of hydraulic cylinder. 

2. Commodity: SAE1571 Chilly drawn hydraulic cylinder tube

3. Dimension selection: 40mm*30mm-580mm*500mm

4. Accessible metal grade: 

five. Manufacture strategy: Chilly rolled, hydraulic chilly drawn, hot rolled+deep hole boring

6. Supply situation: 

seven. Bore remedy: Honing, skiving&roller burnishing

8. Bore roughness control: Ra0.25um max or Ra0, 35um max for honed tubes, Ra0.25um max for skived&roller burnished tubes. 

9. Conclude finish: Simple ends with square cuts, totally free of burrs for honed tubes. Small bevelled finishes for skived&roller burnished tubes. 

10. CZPT export packing: In bundles tied with metal strips. Int&ext oil coating. Stop plastic caps. Exterior packing by PVC luggage and knit bags. 

11. CZPTized packing and marking can be provided upon ask for. 

twelve. H8 tolerance: 

thirteen. Variation among honed tube and skived&roller burnished tube: In hydraulic cylinder market, there are 2 solutions for bore remedy: Honing, and skiving&roller burnishing. Honing or skiving&roller burnishing sales opportunities to diverse internal area image, but the two ensure good roughness.

Part II: Often Asked Questions
one. MOQ: CZPTly Min Get Amount can be two-three tons/measurement for tubes with OD under 250mm, and ten tons/size for tubes with OD previously mentioned 250mm. Occasionally, it relies upon on metal quality you need. If you require special grade like E410, E470 or alloy metal tube, MOQ should be ten tons/size at minimum. 
two. Shipping Time: CZPTly, our shipping and delivery time for honed tubes is all around 40-60 days based on the sizes and quantities. It will get us 15-30 times to get raw material. For example, if you require 3 tons of little dimensions honed tubes 50mm*40mm with roughness of Ra0.25um max, it will take us at minimum 30 times to hone this measurement. 
3. Guarantee&Promise: Guarantee&promise interval is 6 months considering that we produce the tubes, and we are not accountable for top quality dilemma caused by incorrect unloading or storage soon after shipment. We welcome customer’s inspection just before shipment. 
four. Payment Technique: We take payment technique like T/T, L/C, or D/P, but it relies upon on our investigation about consumers. We have a solution to appraise the credit history of buyers from all more than the planet, and time and sum of D/P we can launch is established by the evaluation. 
five. Quality Management: ninety% of the tubes are made from scorching rolled seamless pipes. So, good quality of raw materials identified quality of completed tubes. We acquire raw material from stable suppliers who are leading steel mills, and we inspect the uncooked substance as for every the specifications. During our generation treatment, there is inspection and good quality manage in each and every phase.
