Element I: Product INTRODUCTION

one. Commodity: SAE1571 Cold drawn seamless pneumatic cylinder tube

two. Dimensions range: 40mm*30mm-580mm*500mm

three. Available steel grade: 

four. Manufacture method: Cold rolled, hydraulic cold drawn, very hot rolled+deep gap unexciting

5. Supply situation: 

6. Bore treatment method: Honing, skiving&roller burnishing

7. Bore roughness control: Ra0.25um max or Ra0, 35um max for honed tubes, Ra0.25um max for skived&roller burnished tubes. 

8. Finish complete: Plain ends with square cuts, free of charge of burrs for honed tubes. Tiny bevelled ends for skived&roller burnished tubes. 

9. CZPT export packing: In bundles tied with metal strips. Int&ext oil coating. Finish plastic caps. External packing by PVC bags and knit luggage. 

ten. CZPTized packing and marking can be presented on ask for. 

11. H8 tolerance: 

twelve. Distinction in between honed tube and skived&roller burnished tube: In hydraulic cylinder industry, there are 2 solutions for bore remedy: Honing, and skiving&roller burnishing. Honing or skiving&roller burnishing prospects to different internal area graphic, but the two ensure good roughness.

Part II: Regularly Asked Queries
1. MOQ: CZPTly Min Order Quantity can be 2-3 tons/dimension for tubes with OD beneath 250mm, and 10 tons/dimension for tubes with OD earlier mentioned 250mm. At times, it relies upon on steel grade you need to have. If you require special quality like E410, E470 or alloy steel tube, MOQ must be 10 tons/size at the very least. 
2. Delivery Time: CZPTly, our shipping and delivery time for honed tubes is all around forty-sixty times relying on the dimensions and quantities. It will get us 15-30 days to get raw content. For illustration, if you need 3 tons of little dimensions honed tubes 50mm*40mm with roughness of Ra0.25um max, it will just take us at least thirty days to hone this measurement. 
3. Guarantee&Promise: Warranty&guarantee period of time is 6 months since we deliver the tubes, and we are not dependable for high quality difficulty triggered by mistaken unloading or storage following cargo. We welcome customer’s inspection just before shipment. 
4. Payment Approach: We settle for payment method 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 rating of clients from all more than the globe, and time and sum of D/P we can release is determined by the analysis. 
5. High quality Control: 90% of the tubes are made from sizzling rolled seamless pipes. So, quality of uncooked material identified top quality of completed tubes. We buy raw material from stable suppliers who are top steel mills, and we examine the raw materials as for every the specs. During our generation process, there is inspection and top quality control in each and every phase.
