Application of Carbon Steel Spectacle Flange

　　Hebei Shengtian Group carbon steel spectacle flange is designed and manufactured to securely blank off a piece of equipment with no flow or leakage through a valve during maintenance. The flow has to be valved off and pressure relieved before loosening flange bolts and swinging the blind. Our carbon steel spectacle flanges are made by premium quality materials such as carbon steel, alloy, stainless steel and so on.

　　1. Systematic medium pipes such as steam purging pipes and oil processing medium pipes play a stable role in isolation, at this time, the carbon steel spectacle flange should be installed near the side of the system medium pipes. Of course, for on-line disassembly of ASTM B16.5 A105 Carbon Steel Spectacle Flange, the gate valve should be partitioned near the process medium pipeline side, such a carbon steel spectacle flange is generally marked as normal.

　　2. The inflammable or poisonous medium pipes of the inlet and outlet devices should be equipped with double gate valves, and carbon steel spectacle flange should be installed in the double gate valves. Such carbon steel spectacle flange is generally marked as normally open.

　　3. The device will be used when it starts up. Gate valves should be installed in the pipeline that no longer passes through the medium after normal start-up. The carbon steel spectacle flange is installed on the side of the pipeline with normal five-medium flow, and the carbon steel spectacle flange is normally marked.

　　As a carbon steel spectacle flange manufacturer in China, Hebei Shengtian Group strives to provide the best quality butt weld fittings, industrial flanges, forged fittings and steel pipes for our global customers.
