13. Difference between honed tube and skived&roller burnished tube: In hydraulic cylinder market, there are 2 solutions for bore therapy: Honing, and skiving&roller burnishing. Honing or skiving&roller burnishing prospects to diverse internal floor graphic, but both guarantee very good roughness.

Part II: Often Questioned Questions
1. MOQ: 
CZPTly Min Purchase Quantity can be 2-3 tons/measurement for tubes with OD underneath 250mm, and ten tons/measurement for tubes with OD earlier mentioned 250mm. Often, it relies upon on metal grade you need. If you need special grade like E410, E470 or alloy steel tube, MOQ must be 10 tons/dimension at least. 
2. Shipping and delivery Time: CZPTly, our shipping time for honed tubes is around 40-60 days depending on the dimensions and portions. It will consider us 15-thirty times to get uncooked substance. For instance, if you want 3 tons of small measurement honed tubes 50mm*40mm with roughness of Ra0.25um max, it will take us at least 30 days to hone this measurement. 
three. Guarantee&Promise: Guarantee&promise time period is 6 months considering that we deliver the tubes, and we are not responsible for good quality dilemma caused by mistaken unloading or storage following cargo. We welcome customer’s inspection prior to shipment. 
four. Payment Method: We take payment strategy like T/T, L/C, or D/P, but it depends on our investigation about consumers. We have a solution to assess the credit of customers from all above the planet, and time and quantity of D/P we can release is determined by the evaluation. 
five. High quality Manage: ninety% of the tubes are produced from hot rolled seamless pipes. So, quality of raw materials established high quality of finished tubes. We obtain raw material from steady suppliers who are top metal mills, and we examine the raw material as per the specifications. Throughout our generation procedure, there is inspection and high quality management in every single stage. 

Portion III: Company INTRODUCTION
We are a manufacturer of chilly drawn, chilly rolled, and hydraulic chilly drawn steel tubes with OD upto 356mm given that 2002. Masking an area of about 32000M2, we have 12 common workshops with 2 hydraulic cold drawing benches, 4 chain cold drawing benches, and 2 ERW mills. Our amenities handles all the production procedures from pickling, chilly drawing, heat dealing with, observed cutting, straightening, inspection, packing to even more machining &turning, chilly drawing die fabrication, and equipment repairation&maintenance.
