Designation	Symbol	Description
Cold finished/ hard	BK	Tubes do not undergo heat treatment following the final cold forming and thus have a rather high resistance to deformation
Cold finished/ soft	BKW	The final heat treatment is followed by cold drawing involving limited deformation. Appropriate further processing allows a certain degree of cold forming
Cold finished and stress relieved	BKS	Heat treatment is applied following the last cold forming process. Subject to appropriate processing conditions, the increase in the residual stresses involved enables both forming and machining to a certain degree
Annealed	GBK	The last cold forming process is followed by anneling above the upper transformation point in a controlled atmosphere
Normalized	NBK	The last cold forming process is followed by annealing above the upper transformation point in a controlled atmosphere.

FAQ

1.Are you a trading company or manufacturer?

Yea, we are manufacturer. We have our own manufacturer.

Here is our web site:/

We usually quote within 24 hours after we get your inquiry by telling us the material, out diameter, wall thickness length, quantity and application of the steel pipe which you need. If you are very urgent to get the price, please inform us in email so that we will regard your inquiry priority.

3.How can I get a sample to check your quality?

After price confirmation, you can require for samples to check our quality.
we will provide you the sample for free, however we could only make sure the same material, the
dimension will be much similar as your request but not same. And customer should afford the charge of shipment.

4.How long can I expect to get the sample?

The samples will be sent to you via express and arrive in 3-5 days.
You can use your own consignee account or prepay us if you do not have an account.

5.What about the lead time for mass production?

Honestly, it depends on the order quantity and the season you place the order.

6.What is the Small Qty Process Charge?

It is the payment for customer whose order qty is less then Min Order Qty. Because small qty of products should be processed same in the production flow as big qty and the average cost would get much higher than big ones. So there is a small Qty Process Charge to ensure the profit of our factory and usually the amount of it is about $250.00

7.Could the pipe be customized for us?

Yes. We are the professional manufacturer which has rich experience in Precision Seamless Steel Pipe manufacturing.

We could print the logo and label under your requirements if you need OEM products. Beside this, we still do some refined processes like CNC cutting, chamfering, galvanization and tapping, if you have detailed spec or drawing.Our production lead time is within 30-45 days.

8.What is your terms of delivery?

We accept EXW, FOB, CIF, DDU etc. You can choose the one which is the most convenient or cost effective for you.
