thirteen. Difference between honed tube and skived&roller burnished tube: In hydraulic cylinder industry, there are 2 solutions for bore therapy: Honing, and skiving&roller burnishing. Honing or skiving&roller burnishing prospects to different internal surface picture, but the two ensure very good roughness.

Part II: Regularly Asked Queries
one. MOQ: 
CZPTly Min Purchase Amount can be two-3 tons/size for tubes with OD under 250mm, and 10 tons/dimensions for tubes with OD previously mentioned 250mm. At times, it is dependent on metal grade you require. If you need to have special grade like E410, E470 or alloy steel tube, MOQ ought to be 10 tons/dimension at least. 
two. Shipping Time: CZPTly, our shipping time for honed tubes is around forty-sixty times dependent on the sizes and portions. It will just take us fifteen-thirty days to get uncooked content. For instance, if you require 3 tons of little dimension honed tubes 50mm*40mm with roughness of Ra0.25um max, it will consider us at least thirty times to hone this dimension. 
three. Warranty&Assure: Guarantee&assure period is 6 months since we supply the tubes, and we are not liable for good quality difficulty triggered by incorrect unloading or storage right after shipment. We welcome customer's inspection before cargo. 
four. Payment Method: We settle for payment method like T/T, L/C, or D/P, but it is dependent on our investigation about buyers. We have a solution to appraise the credit of customers from all in excess of the world, and time and sum of D/P we can release is established by the evaluation. 
five. Good quality Manage: ninety% of the tubes are made from scorching rolled seamless pipes. So, quality of uncooked material decided quality of finished tubes. We obtain uncooked materials from stable suppliers who are foremost steel mills, and we inspect the uncooked materials as per the requirements. Throughout our production process, there is inspection and high quality control in each and every stage. 

We are a manufacturer of cold drawn, chilly rolled, and hydraulic chilly drawn steel tubes with OD upto 356mm because 2002. Masking an location of about 32000M2, we have twelve normal workshops with 2 hydraulic cold drawing benches, 4 chain chilly drawing benches, and 2 ERW mills. Our services covers all the creation procedures from pickling, chilly drawing, heat treating, noticed reducing, straightening, inspection, packing to additional machining &turning, cold drawing die fabrication, and products repairation&maintenance.
