Part I: Merchandise INTRODUCTION
1. Description: 
CZPT cylinder pipe is a kind of steel tube utilized to manufacture hydraulic cylinder barrels that is the core component of a piece of hydraulic cylinder. We can manufacture the two chilly drawn pipes ready to hone and bore honed pipes.

two. Commodity: E355 CZPT cylinder pipe

3. Dimension variety: 40mm*30mm-580mm*500mm

4. Accessible steel quality:

Chilly rolled Cold drawn Tension relieved Annealed Normalized Quenched+Tempered

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

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

nine. Stop end: Simple ends with square cuts, free of charge of burrs for honed tubes. Little bevelled ends for skived&roller burnished tubes. 

10. CZPT export packing: In bundles tied with metal strips. Int&ext oil coating. End plastic caps. External packing by PVC baggage and knit baggage. 

eleven. CZPTized packing and marking can be offered on ask for. 

twelve. H8 tolerance:

a hundred and twenty< d ≤180 +/+.063 400< d ≤500 +/+.097

13. Distinction amongst honed tube and skived&roller burnished tube: In hydraulic cylinder business, there are 2 solutions for bore treatment method: Honing, and skiving&roller burnishing. Honing or skiving&roller burnishing qualified prospects to different interior area image, but the two guarantee great roughness.

Component II: Regularly Questioned Inquiries
1. MOQ: 
CZPTly Min Purchase Quantity can be two-3 tons/dimension for tubes with OD beneath 250mm, and 10 tons/measurement for tubes with OD earlier mentioned 250mm. At times, it is dependent on steel grade you need. If you want specific grade like E410, E470 or alloy steel tube, MOQ must be 10 tons/measurement at least. 
2. Delivery Time: CZPTly, our shipping time for honed tubes is about forty-60 days based on the sizes and quantities. It will consider us fifteen-thirty days to get raw materials. For example, if you need to have 3 tons of modest size honed tubes 50mm*40mm with roughness of Ra0.25um max, it will get us at minimum thirty days to hone this dimension. 
3. Warranty&Promise: Guarantee&assure time period is 6 months since we provide the tubes, and we are not responsible for high quality dilemma induced by incorrect unloading or storage after shipment. We welcome customer’s inspection ahead of cargo. 
4. Payment Method: We accept payment method like T/T, L/C, or D/P, but it depends on our investigation about buyers. We have a solution to evaluate the credit history of clients from all over the world, and time and volume of D/P we can launch is determined by the evaluation. 
5. Top quality Control: ninety% of the tubes are produced from scorching rolled seamless pipes. So, high quality of uncooked materials established good quality of completed tubes. We buy raw substance from steady suppliers who are leading steel mills, and we examine the raw materials as for each the specs. For the duration of our production method, there is inspection and good quality manage in every stage. 

We are a manufacturer of chilly drawn, chilly rolled, and hydraulic cold drawn metal tubes with OD upto 356mm because 2002. Covering an region of about 32000M2, we have 12 regular workshops with 2 hydraulic cold drawing benches, 4 chain cold drawing benches, and 2 ERW mills. Our services handles all the manufacturing procedures from pickling, chilly drawing, heat dealing with, saw slicing, straightening, inspection, packing to further machining &turning, chilly drawing die fabrication, and equipment repairation&servicing.
