cold rolling precision stel pipe hot-sales features

Cold Rolling Production Process Method JIS G3445 Standard STKM 11A Bright Precision Seamless Steel Pipes is one of our hot-sale commodities, which is newly developed these years. Due to cold rolling products' features like good precision size and bright surface, it is getting more and more attention and acception from cleints. We are giving its magnificent advantages as follows:

Main Advantages of cold rollong precision steel pipes:
A. High precision size and much smaller tolerance, this pipe is produced under cold rolling process method. The pipe OD and ID tolerance can be with -0.1/+0.1mm, and even through our 3-roller machine we can control the pipe OD and ID tolerance within -0.05/+0.05mm. There is no oxide skin layer on both inside and outside surfaces, degree of finish is very well.

B.High precision cold rolling seamless steel pipes have good comprehensive mechanical property. It can bear high pressure, cold bending, expanding, pressing flat without crack, and other complex size change and mechanical handling.

C.High precision cold rolling seamless steel pipes being used largely will help save the steel materials, promote the machining efficiency, reduce the expense and decrease processing time on large extent.
So this kind of pipes are widely as deformed bar connection,  automobile components, mechanical engineering parts, hydraulic fittings, bearing, peneumatic components, oil cylinder, boiler equipment and so on.

We would love to give one table to compare the cold rolling precision steel pipes and common hot rolled steel pipes, supposing we need one finished round precision cylinder of finished size OD 55.19mm x ID 42.58mm x Length 1000mm. And we use these two kinds of pipes as the materials.

Comparing Table	cold rolling precision steel pipes	common hot rolled steel pipes
Outside surface bright	Yes	No
Without oxide skin layer	Yes	No
Inside surface smooth	Yes	No
Needing size	55.29x42.48x1000	57x41
Tolerance allowed	-0.1/+0.1 for OD and ID (under 3 rollers -0.05/+0.05)	1% for OD (-0.57/+0.57mm)
Materials weight	7.716kg	9.666kg around
Processing time needed	60minutes	75minutes

From the table we can see cold rolling precision steel pipes have a lot of advantages than the common hot rolled steel pipes.

*Can you do partial shipment?
We will follow client request to do partial shipment or not. Partial shipment is not a problem for us.

*What is your Minimum Order Quantity?
For goods in stocks we supply starting with one piece. Shall it is a production order, the MOQ is 3tons. Please be noted price based on MOQ will be slight higher than FCL condition due to higher unit cost.

*Before cooperation we want a sample for inspecting of quality, is that okay?
  We can provide a free sample for you shall sample value not above 30USD, you only need to pay the express charge. For a sample valued more than 30USD, the express charge and just one half of sample value is on the account of you, and we afford the other half.
