Pipe Flanges to BS10:1962 are designed in accordance with the British Standard BS10, which remains a widely recognized specification for low to medium-pressure flanged connections. These flanges are commonly used in legacy systems and sectors such as marine, water treatment, fire protection, and general industrial piping. The BS10 standard includes a range of pressure classes, organized into tables (A through T), with Tables D, E, F, and H being among the most frequently used for practical installations.

Key features and benefits of Pipe Flanges BS10:1962.

Key Features

BS10 flanges are ideal for non-critical systems operating under moderate pressure. Common pressure tables like D and E suit a wide variety of utility applications.

Key Features

Available as slip-on, blind, weld neck, and threaded flanges. These offer flexibility for different installation and flow requirements.

Key Features

BS10:1962 flanges align with traditional imperial sizing. This makes them a key choice for maintaining or retrofitting older pipeline systems.

Key Features

Manufactured from mild steel, stainless steel, or galvanised materials. These flanges are built for long-term durability in less aggressive environments.

Key Features

Their straightforward geometry allows for custom modifications when needed. Ideal for project-specific requirements and site adjustments.

Key Features

Despite newer standards, BS10 flanges remain widely available and supported. This ensures easy sourcing and replacement across legacy infrastructure.

BS10:1962 flanges are important because they continue to serve as a critical link in older piping systems where modern standards may not align. Many industrial and marine installations built decades ago still rely on BS10 flanges for safe, pressure-rated connections. Using flanges that match the original specification helps maintain the structural integrity of these systems without requiring full redesigns. In maintenance, repair, or upgrade projects—especially within the UK and Commonwealth countries—BS10 flanges offer a straightforward, cost-effective solution that’s trusted, compatible, and widely available.

Pipe flanges to BS10:1962 are most commonly used in marine engineering, water and wastewater systems, fire protection loops, boiler installations, and low-pressure steam systems. They’re also frequently seen in older plant infrastructure and utility systems built before metric and international standards became prevalent. Their continued use ensures seamless compatibility during retrofits and allows engineers to replace components without altering pipework or pressure specifications. Whether it’s on a ship, in a water treatment plant, or in a factory with older pipe layouts, BS10 flanges remain an essential part of many operating systems.

Industries

Pipeline fittings are used to connect straight sections of pipe, change flow direction, adapt pipe sizes, or terminate a piping system. They’re essential for building efficient, flexible, and safe fluid or gas transport networks.

A fitting joins pipes together or modifies flow (e.g., elbows, tees, reducers), while a flange is a flat disc used to bolt two pipe sections or components together. Flanges allow for easier disassembly and maintenance.

They are commonly made from stainless steel, carbon steel, brass, copper, or plastic depending on the application. Stainless steel and carbon steel are preferred for industrial, high-pressure, or high-temperature systems.

Standard pressure ratings include 150lb, 300lb, 600lb, and higher depending on the material and design. The correct pressure class must match your system requirements to ensure safe operation.

ANSI B16.5 is a standard that defines dimensions, tolerances, and pressure ratings for pipe flanges and flanged fittings. It is widely used in industrial and high-pressure piping systems.

It is not recommended unless proper adapters are used. Mixing standards can result in misalignment, poor sealing, or mechanical failure.

Selection depends on factors such as pressure, temperature, fluid type, pipe size, and applicable standards. Material compatibility and environmental conditions should also be considered.

No. For hygienic applications, only stainless steel fittings with smooth, crevice-free surfaces (often polished) and specific certifications (e.g., 3A, FDA) should be used.

Typical fittings include elbows, tees, reducers, caps, nipples, couplings, and unions. Each serves a unique function in controlling direction, flow, or connectivity.

Common types include weld neck, slip-on, blind, threaded, socket weld, and lap joint flanges. Each type serves a different installation or operational need.

Yes, provided they are rated for the appropriate pressure and temperature conditions. Materials like carbon steel or stainless steel are suitable for steam lines.
