Q235 material of flange is the most commonly used in carbon steel flange, is divided into two kinds of casting and forging process of.On the mechanical properties of the forging flange is higher than the casting flange, forging flange structure more uniform, the density is higher, more complete structure, higher strength.
The material of Q235 carbon steel is a kind of steel.Q represents this kind of material yield, behind the 235, is refers to the material yield value, at around 235.And with the increase of the thickness of the material and reduce the yield value.
Q235A, Q235B, Q235C Q235D.And this is the distinction between grade, represents the main impact of temperature is different.
Q235 material of flange can be production for gb standard flange, flange standard, American standard(ANSI,ASME), Japanese standard(JIS) standard flange, Russian GOST standard flange, etc.Use range, high demand, the price is cheap, is a good choice for users of the flange.
Plate flat welding steel pipe flange commonly referred to as "for tablet, also called lap welding flange.Flat welding flange and pipe connection is to insert the pipe flange hole to the appropriate position, then take welding.Flat welding flange is suitable for the pressure level is lower, the pressure fluctuation, the vibration and shock were not serious in the pipeline system. Flat welding flange advantages in flat welding flange welding assembly for more easily, and the price is cheaper, thus has been widely used.Large flat welding flange specifications DN10 - DN2000 with flat welding steel pipe flange neck
