60 seamless steel tubes with 50 flanges, right?
On the next floor, the DN50 seamless pipe has an outer diameter of 60.3 and a flange with DN50. Of course, corresponding to their thickness of SCH? The same thing.
The problem should be this, 60mm seamless steel tubes with DN50 flanges, right?Normally; diameter seamless pipe DN50 welding flange is 57mm, if it is seamless and DN50 matched flange 60mm, seamless processing thread, flange hole machining internal thread, so just.In the form of welding, the DN50 flanges need to be machined and they are also available.
Yes！ But more accurate description is: the outer diameter is 60mm seamless steel pipe, and nominal size of DN50 flange matching connection.
