thirteen. Difference amongst honed tube and skived&roller burnished tube: In hydraulic cylinder sector, there are 2 solutions for bore treatment: Honing, and skiving&roller burnishing. Honing or skiving&roller burnishing qualified prospects to different interior floor impression, but equally guarantee good roughness.

Element II: Frequently Asked Questions
1. MOQ: CZPTly Min Order Quantity can be 2-3 tons/dimensions for tubes with OD under 250mm, and 10 tons/dimension for tubes with OD earlier mentioned 250mm. Occasionally, it depends on metal quality you need to have. If you require particular grade like E410, E470 or alloy steel tube, MOQ should be 10 tons/dimension at minimum.
two. Shipping Time: CZPTly, our supply time for honed tubes is close to 40-60 times dependent on the measurements and portions. It will just take us 15-30 days to get raw substance. For illustration, if you require 3 tons of tiny dimensions honed tubes 50mm*40mm with roughness of Ra0.25um max, it will get us at least thirty days to hone this size.
3. Warranty&Ensure: Warranty&promise time period is 6 months considering that we provide the tubes, and we are not accountable for quality problem brought on by mistaken unloading or storage following shipment. We welcome customer’s inspection ahead of cargo.
4. Payment Strategy: We accept payment approach 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 entire world, and time and quantity of D/P we can launch is determined by the analysis.
five. Quality Handle: 90% of the tubes are made from scorching rolled seamless pipes. So, good quality of uncooked materials decided high quality of completed tubes. We purchase uncooked material from secure suppliers who are foremost metal mills, and we inspect the uncooked content as for every the technical specs. In the course of our generation treatment, there is inspection and high quality management in every single stage.
