The pipes range in dimensions according to the ASTM, ASME and API standards with specifications in ASTM A213, A249 and A269. There are welded as well as seamless pipes. The Stainless Steel Seamless Pipe is dimensionally more accurate than the welded pipes. The pies range in nominal bore sizes from 1/8 inches to 30 inches, and 0.35mm to 6.35 inches in outer diameter and wall thickness ranges from 0.1mm to 1.2mm.
Duplex Steel is a type of stainless steel that has a two-phase microstructure consisting of both austenitic and ferritic grains. It offers excellent strength, corrosion resistance, and high durability. There are several grades of duplex steel, each with unique properties that make them suitable for specific applications. Here is a brief description of duplex steel products with grades.

Stainless Steel Alloy Duplex 2202, DX2202 |
|
Duplex 2202 |
Duplex 2202, or DX2202, is an austenitic-ferritic stainless steel. It offers users general resistance to corrosion that is comparable to Type 304L. Some of the other key characteristics of Duplex 2202 include. |
Stainless Steel Alloy 2507, Duplex 2507 |
|
Duplex 2507 |
Duplex 2507, is a commonly used super duplex stainless steel. Also sold as Alloy 2507, this alloy is used in situations where exceptional strength and corrosion resistance are in demand. |
Stainless Steel Alloy Zeron® 100, Super Duplex Stainless , Super Duplex |
|
Zeron® 100 |
Zeron® 100, which is also sold under the names Super Duplex Stainless and Super Duplex, is a highly alloyed stainless steel that is designed for use in difficult and aggressive environments. Because of its outstanding strength, Zeron 100 is known as a super duplex stainless steel. Originally created for applications that demand corrosion resistance to seawater in the North Sea, Zeron 100 is also perfect for other industries and applications. |
Super Duplex is a type of steel that contains chromium, which makes it highly resistant to rust and corrosion.Duplex & Super Duplexl is commonly used in many industries, including construction, automotive, and aerospace, due to its durability and aesthetic qualities. Here is a brief description of Duplex & Super Duplex pipe, tube, flange, fastener, fittings, and round bar..
