Component I: Solution INTRODUCTION
one. Description: Honed tube is a kind of sleek bore steel tube employed to manufacture hydraulic cylinder barrels that is the core portion of a piece of hydraulic cylinder. 

two. Commodity: CK45 Honed cylinder tube

3. Dimensions range: 40mm*30mm-580mm*500mm

four. Accessible steel quality: 

5. Manufacture strategy: Cold rolled, hydraulic chilly drawn, scorching rolled+deep gap uninteresting

six. Shipping problem: 

seven. Bore treatment method: 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. 

nine. End end: Basic finishes with square cuts, free of charge of burrs for honed tubes. Tiny bevelled finishes for skived&roller burnished tubes. 

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

11. CZPTized packing and marking can be offered on ask for. 

12. H8 tolerance: 

13. Big difference amongst honed tube and skived&roller burnished tube: In hydraulic cylinder market, there are 2 solutions for bore treatment method: Honing, and skiving&roller burnishing. Honing or skiving&roller burnishing prospects to diverse interior floor impression, but the two make certain excellent roughness.

Component II: Regularly Asked Queries
one. MOQ: CZPTly Min Buy Quantity can be two-3 tons/size for tubes with OD below 250mm, and ten tons/dimension for tubes with OD earlier mentioned 250mm. Occasionally, it relies upon on metal quality you need. If you want specific grade like E410, E470 or alloy metal tube, MOQ must be 10 tons/measurement at the very least. 
two. Shipping Time: CZPTly, our shipping time for honed tubes is around forty-sixty days dependent on the sizes and quantities. It will get us fifteen-30 times to get raw content. For example, if you need 3 tons of small dimensions honed tubes 50mm*40mm with roughness of Ra0.25um max, it will get us at minimum 30 times to hone this dimensions. 
3. Guarantee&Guarantee: Warranty&assure period is 6 months because we provide the tubes, and we are not responsible for quality difficulty induced by mistaken unloading or storage right after shipment. We welcome customer’s inspection ahead of cargo. 
four. Payment Method: We acknowledge payment method like T/T, L/C, or D/P, but it depends on our investigation about buyers. We have a solution to evaluate the credit score of consumers from all more than the entire world, and time and amount of D/P we can launch is decided by the evaluation. 
five. Top quality Handle: 90% of the tubes are produced from scorching rolled seamless pipes. So, top quality of uncooked materials decided high quality of concluded tubes. We acquire uncooked content from steady suppliers who are leading metal mills, and we examine the uncooked content as for every the specifications. In the course of our production process, there is inspection and top quality manage in every single stage.
