ASTM ASME A515-60 API 590 150 3/4" Stainless steel blind flange
Description
Stainless steel blind flange is a flange without hole in the middle, which is used to block the pipe opening. From the appearance of blind flange, it is generally divided into plate blind plate, spectacle blind plate, insert plate and backing ring. There are many types of sealing surfaces, including plane, convex, concave convex, tenon and groove surface and ring connecting surface.

Characteristic
Stainless steel blind flange plays the role of isolation and cutting, which is the same as that of head, pipe cap and welding plug. There are generally four production processes, including forging, casting and forging, medium plate cutting and casting. Among them, the price of forging products is the highest, followed by medium plate, and casting and forging is the lowest.
Application
Carbon steel SW flange is widely used in chemical industry, construction, water supply, drainage, petroleum, fire protection, electric power, aerospace, shipbuilding and other basic projects.
