13. Distinction amongst honed tube and skived&roller burnished tube: In hydraulic cylinder industry, there are 2 solutions for bore treatment: Honing, and skiving&roller burnishing. Honing or skiving&roller burnishing prospects to different interior floor picture, but the two guarantee good roughness.

Element II: Usually Requested Inquiries
1. MOQ: 
CZPTly Min Purchase Amount can be 2-three tons/dimension for tubes with OD under 250mm, and 10 tons/size for tubes with OD earlier mentioned 250mm. At times, it relies upon on steel quality you require. If you require unique quality like E410, E470 or alloy metal tube, MOQ need to be 10 tons/dimension at least. 
two. Supply Time: CZPTly, our shipping and delivery time for honed tubes is about forty-sixty times dependent on the dimensions and quantities. It will take us 15-30 days to get raw material. For instance, if you need 3 tons of tiny size honed tubes 50mm*40mm with roughness of Ra0.25um max, it will just take us at least thirty times to hone this dimension. 
three. Guarantee&Promise: Guarantee&ensure interval is 6 months considering that we provide the tubes, and we are not dependable for good quality difficulty triggered by wrong unloading or storage right after cargo. We welcome customer’s inspection prior to cargo. 
4. Payment Method: We settle for payment approach like T/T, L/C, or D/P, but it relies upon on our investigation about buyers. We have a solution to appraise the credit history of customers from all in excess of the entire world, and time and sum of D/P we can launch is decided by the analysis. 
five. Quality Management: ninety% of the tubes are produced from very hot rolled seamless pipes. So, top quality of uncooked substance identified top quality of concluded tubes. We obtain uncooked substance from steady suppliers who are leading steel mills, and we inspect the uncooked substance as per the specs. In the course of our creation process, there is inspection and top quality control in each stage. 

Component III: Company INTRODUCTION
We are a manufacturer of cold drawn, cold rolled, and hydraulic cold drawn steel tubes with OD upto 356mm since 2002. Covering an spot of about 32000M2, we have 12 regular workshops with 2 hydraulic chilly drawing benches, 4 chain chilly drawing benches, and 2 ERW mills. Our services handles all the creation procedures from pickling, cold drawing, warmth managing, observed slicing, straightening, inspection, packing to further machining &turning, chilly drawing die fabrication, and products repairation&routine maintenance.
