Part I: Product INTRODUCTION

1. Description: Honed tube is a kind of sleek bore steel tube used to manufacture hydraulic cylinder barrels that is the core portion of a piece of hydraulic cylinder. 

two. Commodity: SAE1045 Chilly drawn hydraulic cylinder tube

3. Measurement variety: 40mm*30mm-580mm*500mm

four. Available steel quality: 

five. Manufacture method: Cold rolled, hydraulic cold drawn, hot rolled+deep gap boring

6. Shipping issue: 

7. Bore treatment method: Honing, skiving&roller burnishing

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

9. End finish: Plain ends with sq. cuts, free of burrs for honed tubes. Minor bevelled finishes for skived&roller burnished tubes. 

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

11. CZPTized packing and marking can be offered upon request. 

12. H8 tolerance: 

thirteen. Big difference in between honed tube and skived&roller burnished tube: In hydraulic cylinder sector, there are 2 solutions for bore treatment method: Honing, and skiving&roller burnishing. Honing or skiving&roller burnishing leads to diverse inner floor image, but equally guarantee excellent roughness.

Part II: Often Requested Queries
1. MOQ: CZPTly Min Purchase Amount can be 2-three tons/measurement for tubes with OD underneath 250mm, and ten tons/dimensions for tubes with OD over 250mm. Occasionally, it relies upon on steel grade you want. If you want specific grade like E410, E470 or alloy steel tube, MOQ must be ten tons/measurement at the very least. 
two. Shipping Time: CZPTly, our supply time for honed tubes is about forty-60 days dependent on the dimensions and quantities. It will just take us fifteen-thirty days to get raw materials. For case in point, if you require 3 tons of small measurement honed tubes 50mm*40mm with roughness of Ra0.25um max, it will just take us at least thirty days to hone this measurement. 
3. Warranty&Promise: Guarantee&guarantee time period is 6 months given that we supply the tubes, and we are not accountable for quality issue caused by wrong unloading or storage right after shipment. We welcome customer’s inspection just before cargo. 
four. Payment Strategy: We accept payment method like T/T, L/C, or D/P, but it relies upon on our investigation about clients. We have a solution to evaluate the credit score of buyers from all more than the planet, and time and amount of D/P we can launch is decided by the analysis. 
five. Quality Manage: 90% of the tubes are manufactured from scorching rolled seamless pipes. So, good quality of uncooked content established high quality of completed tubes. We buy uncooked substance from secure suppliers who are leading metal mills, and we inspect the uncooked content as for each the specifications. In the course of our manufacturing method, there is inspection and quality control in each stage. 

Element III: Company INTRODUCTION
