Flanges are important parts of industrial piping systems that are used to bind the pipes, valves, and pumps among other equipment. With small utility pipelines through to large scale oil and gas plants, proper choice of flanges will make them safe, perform well and offer long services to the user. The Flanges Weight Chart is one of the most significant technical documents that are used in selections of flanges and it is a document that contains standardized details of weights of various flange sizes, pressure classes and types.
An industrial flange weight chart is a popular tool with industrial flange manufacturers, bulk flange suppliers, EPC contractors, and providers to make sure that they plan materials correctly, estimate costs and manage logistics. Accurate weight information will enable purchasers and engineers to compare items, procurement specification and prevent expensive mistakes in procurement and installation.
What Is a Flange Weight Chart?
A flange weight chart is a technical table that indicates the approximate/standard weight of flanges with regard to such parameters as the nominal pipe size (NPS), pressure rating (Class 150, 300, 600, etc.), and flange type. Such charts are typically made in the international standards such as ASME B16.5, ASME B16.47, DIN, EN, and JIS.
The chart enables the engineers and the procurement departments to quickly know the weight of a particular flange before it is produced, ordered or installed. This fact is essential in designing the structural support, transportation and on-site handling.

The use of Flanges Weight Chart in Piping Systems is important.
There is more than numbers to flange weight: it is the matter with direct impact on the system safety and efficiency of the project. The wrong assumption regarding the weight of the flange may result in the wrong pipe supports, unacceptable lifting methods, and hidden cost increases.
Importance of flanges weight charts:
- Helps engineers compute loads and stresses in pipeline.
- Helps in the choice of correct pipe supports and brackets.
- Enhances safety in the lifting, handling, and installation.
- Facilitates accurate estimation of costs on materials and transportation.
- Minimizes chances of placing wrong flange orders.
Flange variations and types of the flanges.
The various types of flanges possess various designs and this directly affects the weight. The flange weight may not be very close even in the same size and pressure category.

Usually used types of flanges listed in weight charts:
Weld Neck Flanges
The long tapered hub of these flanges gives them high strength and stress distribution making them heavy. They are usually applied in high pressure and high temperature applications.
Slip-On Flanges
Slip-on flanges are relatively lighter than the weld neck flanges and they take less time to install. They tend to be employed in the situations that do not demand a high level of pressure.
Blind Flanges
Blind flanges are discs of solid material that are employed to seal the ends of the pipelines. They weigh more typically, as they lack a bore and they need the additional material.
Socket weld and threaded flanges.
These flanges are applied in pipelines with a small diameter and tend to be less weighty as compared to the weld neck flanges of similar size.
Influencing Factors Flange weight.
The weight of a flange is affected by several technical reasons, and all these are expressed in a typical flange’s weight chart.
