What Is The Marking Method Of Stainless Steel Flange?

Stainless steel flange markings can be said to be the model of the flange, from the mark can be read out the corresponding parameters and specifications, such as its nominal size, nominal pressure, seal surface form code, with the steel Pipe series code and standard number. Tags example: nominal size of the diameter of 80mm, nominal pressure 4.0MPa (25bar) of convex face welded steel pipe stainless steel flange (with rice tube).

Stainless steel flange should be nominal size, nominal pressure, seal surface form code, with the steel Pipe series code and standard number for marking. Tags example: nominal size of the diameter of 80mm, nominal pressure 4.0MPa (25bar) of convex face welded steel pipe stainless steel flange (with rice tube).

Stainless steel Flange is a disk-like parts, the most common in pipeline engineering, stainless steel flange is used in pairs.

The connection parts which are bolted at the same time in two planes and are closed in the periphery, generally referred to as "stainless steel flange", such as the connection of the ventilation pipe, this kind of part can be called "STAINLESS steel flange parts". But this connection is only a part of the equipment, such as stainless steel flange and pump connection, it is not good to call the pump " Stainless Steel Flange Parts ". Relatively small such as valve can be called" STAINLESS steel Flange-type parts. "

In pipeline engineering, stainless steel flange is mainly used for pipe connection. Inthe pipeline that needs to be connected, a variety of installation of a stainless steelflange, low pressure pipe can use stainless steel flange, 4 kg of pressure of the use of welded stainless steel flanges. Two pieces of stainless steel flange with a sealing point, and then with bolts fastening. Stainless steel flanges with different pressure have different thicknesses and use different bolts. Pumps and Valves , in connection with the pipeline, these equipment parts, also made of the corresponding stainless steel flange shape, also known as stainless steel flange connection.
