The outer diameter of UNS N04400 pipes that we could do is from 0.4MM to 850MM,The thickness of UNS N04400 that we could do is from 0.12MM to 100MM

We could meet size tolerance for UNS N04400 Pipes is as follows:OD : + ± 0.5% of specified diameter based on circumferential measurement. Thick : Minimum thickness at any point not more than 0.3 mm under nominal thi,Out of Roundness : difference between maximum and minimum OD 1% ,Straightness : 3 mm in 3 mtrs

Length : As per customer specification

As per surface finish of UNS NO4400 pipes, we could do pickled and polish into bright surface as per the requirement of the clients, also for bright surface of UNS N04400 pipes, we could meet 2D finish.No. 4 Finish,No. 6 Finish,No. 7 Finish as per the requirement of the clients

UNS N04400 is a Nickel-Copper alloy with high strength and excellent corrosion resistance in a range of acidic and alkaline environments and especially suitable for reducing conditions. It also has good ductility and thermal conductivity.
