DIN and ANSI flanges are not compatible. Flanges of different standards cannot be used in combination directly due to differences in size, thread, etc. For example, the differences between ANSI and DIN standards are large, and these two types of flanges cannot be used directly together. Even if the flanges of the two standards look similar, they may not be matched due to slight size differences.
In order to solve the compatibility problem between flanges of different standards, conversion flanges can be used. Conversion flanges are a special flange that can convert the interface of flanges of two different standards. For example, when using ANSI standard flanges to connect DIN standard flanges, ANSI/DIN conversion flanges can be used to connect the two. At the same time, since conversion flanges have a greater impact on the safety and stability of the pipeline system, products with stable performance and reliable quality should be selected.

Why are dimensions and wall thickness so important when purchasing carbon steel pipe fittings?
In piping engineering, although carbon steel pipe fittings are small in size, they directly impact the connectivity, pressure-bearing capacity, and operational stability of the piping system. When purchasing, buyers should not focus solely on price; dimensional accuracy and wall thickness control are equally critical indicators.

In industrial pipeline projects such as oil and gas, chemical, power, shipbuilding, and construction, carbon steel pipe fittings, although merely connecting components within the pipeline system, directly impact the system's installation, sealing, and long-term operation.

Working Principle of Carbon Steel Flanges
Cast flanges feature rough external shapes but precise dimensions, require minimal machining, and offer low costs; however, they are prone to casting defects (such as porosity) and cracks (often due to inclusions), and their internal structure is suboptimal (resulting in poor grain flow characteristics after cutting).
