12. Distinction between honed tube and skived&roller burnished tube: In hydraulic cylinder business, there are 2 solutions for bore therapy: Honing, and skiving&roller burnishing. Honing or skiving&roller burnishing qualified prospects to diverse inside surface area picture, but each make sure very good roughness. 



Part II: Regularly Requested Queries
1. MOQ: 
CZPTly Min Buy Quantity can be 2-3 tons/dimension for tubes with OD below 250mm, and 10 tons/dimensions for tubes with OD earlier mentioned 250mm. Sometimes, it relies upon on metal grade you require. If you require special grade like E410, E470 or alloy steel tube, MOQ must be ten tons/size at least. 
2. Shipping and delivery Time: CZPTly, our supply time for honed tubes is close to forty-sixty days relying on the measurements and quantities. It will consider us 15-30 times to get uncooked materials. For illustration, if you need to have 3 tons of small dimensions honed tubes 50mm*40mm with roughness of Ra0.25um max, it will just take us at minimum 30 times to hone this dimensions. 
three. Warranty&Promise: Warranty&assure period of time is 6 months considering that we deliver the tubes, and we are not responsible for high quality difficulty caused by mistaken unloading or storage right after shipment. We welcome customer’s inspection just before shipment. 
4. Payment Method: We accept payment technique like T/T, L/C, or D/P, but it is dependent on our investigation about customers. We have a solution to assess the credit history of clients from all more than the globe, and time and amount of D/P we can launch is established by the evaluation. 
5. Top quality Handle: ninety% of the tubes are produced from scorching rolled seamless pipes. So, good quality of uncooked material established quality of finished tubes. We obtain raw materials from stable suppliers who are leading steel mills, and we examine the raw substance as for every the requirements. During our manufacturing treatment, there is inspection and good quality control in every single stage. 

Component III: Business INTRODUCTION
We are a manufacturer of cold drawn, cold rolled, and hydraulic cold drawn steel tubes with OD upto 356mm given that 2002. Covering an region of about 32000M2, we have 12 normal workshops with 2 hydraulic cold drawing benches, 4 chain chilly drawing benches, and 2 ERW mills. Our facilities handles all the manufacturing processes from pickling, chilly drawing, heat dealing with, noticed cutting, straightening, inspection, packing to additional machining &turning, cold drawing die fabrication, and gear repairation&servicing.
