2. Our Service

20G Best Selling steel pipe 400 diameter Various Diameter steel pipe fittings dimensions

* 1  .can cut the seamless steel pipe into the length you demand

* 2  .can make the surface to be bright by milling and grinding at the Lathe

* 3  .can grind the outer diameter and wall thickness to be the dimension you demand.

* 4  .can make steel pipes deep processing

If the sizes are not available from the standard common stock sizes, and the quantity are not enough for the new production, then we need process the stock larger seamless pipes into the sizes you need. For example, size OD250x ID200 is not stock common size, then need using larger pipe to process into 250x 200, same as OD170xID100
