What is the difference between carbon steel flanges and stainless steel flanges?

Flange is a disk-shaped part, z is common in pipeline engineering, flanges are used in pairs. In pipeline engineering, the flange is mainly used for pipeline connection. In the pipeline that needs to be connected, a variety of installation of a piece of flange, low-pressure pipeline can use silk flange, more than 4 kilograms of pressure use welding flange. The gasket is added between the two pieces of flanges, and then tightened with bolts. Different pressure flanges have different thickness and use different bolts.

The main role of the flange 1, connecting the pipeline and keep the pipeline sealing performance; 2, to facilitate the replacement of a section of the pipeline; 3, to facilitate the dismantling and inspection of the pipeline; 4, to facilitate the closure of a section of the pipeline.

 Stainless steel flange: flange (Flange) also called flange or flange. Flange is to make the pipe and pipe interconnection parts, connected to the pipe end. Flange on the eyelets, bolts to make the two flanges tightly connected. Gasket sealing between flanges. The flange is divided into threaded connection (silk) flange and welded flange.

Carbon steel has not deliberately added alloying elements of steel, stainless steel is to prevent rust and add high alloy content of steel. Stainless steel is far more expensive than carbon steel. These two steel uses are not the same, can not be compared to good or bad, carbon steel is usually stronger than stainless steel, but easy to rust. The common classification of carbon steel is hot rolled, cold rolled, galvanized, silicon steel, rebar, wire rod, work angle channel, etc.; stainless steel main categories are 200 series, 300 series, 400 series, 500 series, 600 series, 900 series and so on.

The difference between carbon steel flange and stainless steel flange lies in the stainless steel flange added nickel, chromium, molybdenum, titanium, niobium, and other alloying elements. In addition, not all stainless steel flange is not rust, only in all kinds of stainless steel material allows the conditions to not rust or extend the rust time.
