300Lbs Steel Flat Welded Plate Flange
300Lbs steel flat welded plate flange is a common type of flange, mainly used in piping systems that need to withstand high pressure and temperature fluctuations, with simple structure, easy to manufacture and other characteristics.
Overview
Basic Information
Pressure level: 300Lbs (equal to 20.68MPa)
Material: usually use carbon steel, stainless steel and other materials
Structure: Flat welded plate flange consists of a flat plate and bolt holes, connecting the flange to the pipeline through bolts
Sealing surface: usually adopts flat or protruding surface sealing to ensure the hermeticity of the connection.
Processing: Produced by heat treatment, die forging, sawing, free forging and CNC machining.
Applications
Pipeline engineering: Used to connect two sections of pipeline, suitable for conveying various media, such as water, oil, gas and chemical liquids.
Mechanical engineering: for use in systems such as kettles, heat exchangers and pumps.
Steel structure engineering: used for supporting structures, connecting beams and columns, etc. Its light weight, low cost as well as easy processing make it a popular choice in design.
Other industrial applications: widely used in piping systems in metallurgy, food and pharmaceutical industries.
