Duplex Steel Flanges
ACE ALLOYS LLP is one of the leading manufacturing house & trader for high quality Duplex Steel Pipe Flanges , which has higher alloy content and makes it a superior and corrosion resistance and strength. The processing with the saw is a mechanical processing of the material, which results in a significantly lower unintended deformation and increased hardness for the existing structure, such as the thermal cutting.
These Duplex Steel Slip On Flanges offered by ACE ALLOYS has excellent resistance to uniform, pitting, crevice corrosion and chloride stress corrosion cracking. Its application are in Oil and gas industry equipment, Offshore platforms, heat exchangers, process and service water systems, fire - fighting systems, injection and ballast water systems, Chemical process industries, heat exchangers, vessels, and piping, Desalination plants, high pressure RO plants and seawater piping.
In dilute sulphuric acid contaminated with chloride ions, these Duplex Steel Weld Neck Flanges offered by ACE ALLOYS has better corrosion resistance than 904L, which is specially designed to resist pure sulphuric acid. The machined work piece has a homogeneous structure even at the edge, which does not change in the continuation of the material. The high chromium and molybdenum content of Duplex Steel Socket Weld Flanges makes it extremely resistant to uniform corrosion by organic acids like formic and acetic acid. ACE ALLOYS also offer these Duplex Stainless Steel Flanges in different sizes, shapes and designs as per customers’ specifications at affordable rates.
