thirteen. Big difference among 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 distinct interior floor picture, but each make certain very good roughness.

Element II: Often Asked Queries
1. MOQ: 
CZPTly Min Get Amount can be two-3 tons/dimension for tubes with OD beneath 250mm, and ten tons/measurement for tubes with OD earlier mentioned 250mm. Sometimes, it is dependent on metal grade you want. If you require special grade like E410, E470 or alloy steel tube, MOQ need to be 10 tons/dimensions at minimum. 
two. Shipping Time: CZPTly, our shipping time for honed tubes is all around forty-60 times based on the sizes and portions. It will just take us fifteen-thirty days to get uncooked materials. For example, if you require 3 tons of little size honed tubes 50mm*40mm with roughness of Ra0.25um max, it will consider us at least 30 days to hone this measurement. 
3. Warranty&Ensure: Guarantee&promise period of time is 6 months since we supply the tubes, and we are not dependable for good quality difficulty induced by wrong unloading or storage soon after cargo. We welcome customer’s inspection prior to shipment. 
four. Payment Strategy: We acknowledge payment technique like T/T, L/C, or D/P, but it depends on our investigation about buyers. We have a solution to consider the credit of clients from all in excess of the globe, and time and volume of D/P we can release is decided by the evaluation. 
5. High quality Manage: 90% of the tubes are made from very hot rolled seamless pipes. So, good quality of uncooked material established top quality of finished tubes. We buy uncooked material from secure suppliers who are foremost steel mills, and we examine the raw material as per the technical specs. In the course of our generation treatment, there is inspection and good quality management in each and every stage.
