The material requirement of forged flange in French forged blue connection is to connect two pipes, pipe fittings or equipment. First, they are fixed between the flange plate and the two flange plates, and the gasket is bolted together. To complete the connection.American standard EN1092-1 P245GH flangeSome pipe fittings and equipment have their own flange plates, which are also flange connections. Below, now take you to understand the material requirements of forged flange.

The hardenability of the forged flange is very poor, and the hardness of its heart is generally only above 30 degrees. Under normal circumstances, forging chromium content of 0.1~0.5% of the flange, often using water quenching treatment.American standard EN1092-1 P245GH flange

The hardenability of the forged flange is very poor, and the hardness of its heart is generally only above 30 degrees. Under normal circumstances, flange forging is often treated with water quenching, and the chromium content is 0.1 to 0.5 (flange forging generally does not contain chromium). The carbon content is less than 1.0%, and the forged blue is forged at high temperature. Although the surface hardness (HRC) of some forged blue can reach 56 (the hardened layer is only about 15mm), due to the poor hardenability of the forged flange, its core hardness is generally only above 30 degrees. Under normal circumstances, water quenching is often used when forging flanges.American standard EN1092-1 P245GH flange

Forging method-blue connection is to fix two pipes, fittings or equipment on the flange plate. The two flange plates, together with the flange pads, are bolted together to complete the connection. Some pipe fittings and equipment have their own flange plate, which is also a flange connection. American standard EN1092-1 P245GH flange

Forging method-blue connection is an important connection mode in pipeline construction. The forged flange connection is easy to use and can withstand great pressure. In industrial pipelines, stamping elbows are widely used to connect Fa and Lan. At home, the pipe diameter is small and the pressure is low, so the connection between Fa and Lan cannot be seen.American standard EN1092-1 P245GH flange

If you are in a boiler room or production site, there are pipes and equipment connecting Fa and Lan everywhere.
