7. Bore remedy: Honing, skiving&roller burnishing

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

9. End end: Plain finishes with square cuts, totally free of burrs for honed tubes. Small bevelled ends for skived&roller burnished tubes. 

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

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

twelve. H8 tolerance:

120< d ≤180 +/+.063 four hundred< d ≤500 +/+.097

13. Big difference among honed tube and skived&roller burnished tube: In hydraulic cylinder business, there are 2 solutions for bore treatment: Honing, and skiving&roller burnishing. Honing or skiving&roller burnishing prospects to different internal surface area impression, but each guarantee excellent roughness. 

Inner Area Situation OF HONED TUBES:


Element II: Usually Questioned Questions
1. MOQ: 
CZPTly Min Order Amount can be 2-three tons/dimensions for tubes with OD below 250mm, and ten tons/measurement for tubes with OD above 250mm. Often, it is dependent on metal quality you need to have. If you want particular grade like E410, E470 or alloy steel tube, MOQ need to be ten tons/measurement at least. 
2. Delivery Time: CZPTly, our delivery time for honed tubes is all around forty-sixty days relying on the dimensions and quantities. It will just take us 15-30 times to get raw content. For illustration, if you need 3 tons of tiny size honed tubes 50mm*40mm with roughness of Ra0.25um max, it will get us at the very least 30 days to hone this dimension. 
3. Warranty&Guarantee: Warranty&assure time period is 6 months since we provide the tubes, and we are not responsible for good quality issue induced by wrong unloading or storage after cargo. We welcome customer’s inspection just before shipment. 
four. Payment Method: We acknowledge payment approach like T/T, L/C, or D/P, but it relies upon on our investigation about consumers. We have a solution to consider the credit of buyers from all over the entire world, and time and sum of D/P we can release is identified by the analysis. 
five. Quality Management: ninety% of the tubes are made from hot rolled seamless pipes. So, good quality of raw substance decided high quality of concluded tubes. We obtain uncooked material from steady suppliers who are leading metal mills, and we examine the uncooked substance as for each the technical specs. In the course of our production treatment, there is inspection and top quality manage in each and every stage. 

We are a manufacturer of chilly drawn, chilly rolled, and hydraulic chilly drawn steel tubes with OD upto 356mm given that 2002. Masking an location of about 32000M2, we have twelve normal workshops with 2 hydraulic chilly drawing benches, 4 chain chilly drawing benches, and 2 ERW mills. Our services addresses all the production techniques from pickling, chilly drawing, heat dealing with, saw slicing, straightening, inspection, packing to further machining &turning, chilly drawing die fabrication, and products repairation&maintenance.
