Trusted & verified: blind flange weight chart in mm/kg – easy-to-use pdf for b2b buyers

Pipex ai is the B2B portal trusted by industrial buyers for sourcing top-grade piping components built for critical performance. One of our most in-demand products is the blind flange, an essential pipe fitting used to seal off the end of a piping system or pressure vessel.

Unlike other flanges, blind flanges have no opening in the center. They are solid discs, designed to stop flow completely and withstand internal pressure. Their primary purpose is to allow easy access for future expansion, maintenance, or inspection, while ensuring a tight seal under high pressure. They are commonly used in sectors like oil & gas, petrochemical, power generation, water treatment, and marine engineering—industries where safety, pressure tolerance, and long-term reliability are paramount.

Blind flanges are usually bolted to another flange and require gaskets to ensure a leak-proof seal. Depending on the project requirements, they are available in various materials, including stainless steel, carbon steel, and alloy steel, and are manufactured according to global standards such as ASME B16.5 or ANSI. To ensure accurate handling and planning, referencing a blind flange weight chart in kg is essential for understanding the weight involved in your application.

Given their solid construction, blind flanges are heavier than other flange types of the same size and class. This makes it essential to understand their weight before planning transport, installation, or structural design. That’s where a blind flange weight chart in kg pdf becomes an indispensable reference.

Importance of the Weight Chart in Blind Flange Selection

A weight chart provides standardized data that indicates the approximate weight of blind flanges based on their nominal pipe size (NPS) and pressure class. For industries working with load-sensitive structures or elevated pipe systems, this information is crucial. It helps engineers and logistics planners estimate lifting requirements, calculate shipping loads, and avoid over-stressing piping supports.

The weight of a blind flange depends on its pressure rating, size, and material. For instance, a 6-inch Class 300 flange weighs far more than a 6-inch Class 150 flange, and that difference must be accounted for during the planning phase. With a clear weight chart, buyers and project managers can make informed decisions quickly, without relying on estimates or risking improper installation.

At Pipex ai, we provide accurate weight chart data with all flange product listings, allowing B2B buyers to make confident, data-driven purchases.

At Pipex Ai, we recognize that in today’s fast-paced B2B Marketplace, buyers need more than just products—they need clarity, consistency, and reliable data. That’s why we go beyond simple listings by offering technical support, accurate weight charts, and guidance throughout the selection process.

Blind flanges are critical for sealing, safety, and future-ready piping systems. Their durability and pressure resistance make them a staple in industrial applications. But to choose the right blind flange, understanding its weight is just as important as knowing its size or material. A weight chart ensures that no aspect is overlooked.

At Pipex Ai, we make this process simple and transparent—helping B2B buyers make smart, efficient, and confident decisions every time.
