The outer diameter of UNS N08031 pipes that we could do is from 0.4MM to 850MM,The thickness of UNS N08031 that we could do is from 0.12MM to 100MM

We could meet size tolerance for UNS N08031 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 NO8031 pipes, we could do pickled and polish into bright surface as per the requirement of the clients, also for bright surface of UNS N08031 pipes, we could meet 2D finish.No. 4 Finish,No. 6 Finish,No. 7 Finish as per the requirement of the clients

UNS N08031 is characterized by outstanding resistance to corrosion in halide media, both acidic and basic; outstanding resistance to sulfuric acid, even highly concentrated; outstanding resistance to corrosion and erosion-corrosion in phosphoric acid media; excellent resistance to both localized corrosion and general corrosion in chlorine dioxide bleach media; excellent resistance to both reducing and oxidizing media, and ease of fabrication and welding. Approval for pressure-vessel use involving wall temperatures from -196 to 550oC (-320 to 1020oF).
