thirteen. Distinction among 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 qualified prospects to distinct inner floor impression, but both guarantee excellent roughness.

Portion II: Frequently Requested Queries
one. MOQ: CZPTly Min Purchase Amount can be 2-3 tons/measurement for tubes with OD underneath 250mm, and ten tons/dimension for tubes with OD over 250mm. Occasionally, it relies upon on steel quality you require. If you need unique grade like E410, E470 or alloy metal tube, MOQ ought to be ten tons/dimensions at least. 
two. Supply Time: CZPTly, our shipping and delivery time for honed tubes is all around forty-60 days based on the measurements and portions. It will take us fifteen-30 days to get uncooked material. For case in point, if you want 3 tons of modest dimension honed tubes 50mm*40mm with roughness of Ra0.25um max, it will get us at the very least thirty days to hone this dimension. 
3. Warranty&Ensure: Guarantee&ensure interval is 6 months because we provide the tubes, and we are not liable for good quality difficulty brought on by mistaken unloading or storage after shipment. We welcome customer’s inspection ahead of cargo. 
four. Payment Technique: We take payment technique like T/T, L/C, or D/P, but it relies upon on our investigation about customers. We have a solution to assess the credit score of customers from all more than the entire world, and time and amount of D/P we can launch is identified by the evaluation. 
5. Quality Handle: ninety% of the tubes are produced from scorching rolled seamless pipes. So, good quality of uncooked content established quality of finished tubes. We buy uncooked substance from steady suppliers who are leading steel mills, and we examine the uncooked content as for each the requirements. During our generation procedure, there is inspection and good quality manage in each and every phase. 

Part III: Business INTRODUCTION
We are a manufacturer of chilly drawn, chilly rolled, and hydraulic cold drawn steel tubes with OD upto 356mm because 2002. Masking an location of about 32000M2, we have twelve regular workshops with 2 hydraulic chilly drawing benches, 4 chain chilly drawing benches, and 2 ERW mills. Our facilities covers all the generation methods from pickling, chilly drawing, heat treating, saw cutting, straightening, inspection, packing to further machining &turning, cold drawing die fabrication, and products repairation&maintenance.
