BS4504 Welding Neck111 PN6 PN10 PN16 PN25 PN40

The BS4504 Welding Neck111 PN6 PN10 PN16 PN25 PN40 refers to a set of welding neck flanges that are specified by the British Standard BS4504. These flanges come in different pressure ratings, namely PN6, PN10, PN16, PN25, and PN40, each having different dimensions and pressure capabilities.

Here are some key details about these flanges:

• Dimensions: The dimensions of these flanges vary based on the pressure rating (PN6, PN10, PN16, PN25, or PN40). Each pressure rating represents a different set of dimensions.
• Production Technique: These flanges are typically forged, heat-treated, and machined.
• Applications: They are widely used in various industries including petroleum, chemical industry, nuclear power plant, food manufacturing, construction, shipbuilding, papermaking, medicine, and others.
• Advantages: One of the main advantages of this flange type is, it provides a good connection and sealing in high-pressure applications
