Description of BS4504 Slip On Flanges:
The slip on flange serves as a straightforward and effective substitute for a weld neck flange due to its lack of a weld bevel, allowing for adjustments in pipe length relative to the flange position. The bore of the slip-on provides ample space for the pipe to fit, offering sufficient working space for welders and fabricators during installation.
This type of flange is commonly used in applications with lower pressure requirements. Most slip on flanges feature a hub that resembles a raised face in terms of dimensions. However, they can also be supplied without a hub for space-constrained situations, using a "ring style" slip on instead. While the hub style is more prevalent, a ring-style slip-on without a hub still falls under the slip on flange category and can be specified accordingly. In higher pressure classes, slip on flanges are often designed with a lap joint height for improved connections. When hub height is not a concern and lap joint isn't readily available, customers may opt for a slip-on designed in a lap joint style with a machined hub.
Slip on flanges are predominantly used in lower pressure systems and are less common in high-stress applications where a stronger connection is required. This is because slip-on flanges accommodate pipe joints with fillet welds, while weld neck flanges feature a reinforced hub at the base for a weld bevel connection directly to the pipe's butt weld end. The tapered hub of a weld neck flange provides enhanced strength in environments with mechanical stress.

Materials of BS4504 Slip On Flanges:
BS4504 slip on flanges are available in various materials to suit different applications and operating conditions. The material selection for BS4504 slip on flanges depends on factors such as temperature, pressure, corrosion resistance, and compatibility with the conveyed fluid or gas.
Grades of Carbon Steel Slip On Flanges:
ASTM A105: This is a common grade of carbon steel used for slip on flanges. It is a forged carbon steel specifically designed for high-temperature service and offers excellent weldability and toughness.
ASTM A350 LF2: LF2 is a low-temperature carbon steel grade commonly used for slip on flanges in applications where low-temperature toughness is required.
ASTM A694 F52/F60/F65/F70: These grades are high-yield carbon steel materials used for slip on flanges in applications requiring high strength and impact resistance.
Grades of Stainless Steel Slip On Flanges:
ASTM A182 F304/F304L: These grades of stainless steel are austenitic and commonly used for slip on flanges. They offer good corrosion resistance, excellent weldability, and are suitable for a wide range of applications.
ASTM A182 F316/F316L: Similar to F304/F304L, these grades are also austenitic stainless steels with improved corrosion resistance, particularly in chloride environments.
ASTM A182 F321: F321 is an austenitic stainless steel grade containing titanium, which provides enhanced resistance to intergranular corrosion. It is often used for slip on flanges in high-temperature applications.
ASTM A182 F347: F347 is a stabilized stainless steel grade with the addition of niobium, which improves its resistance to intergranular corrosion. It is commonly used for weld neck flanges in applications involving elevated temperatures.
When Should BS4504 Slip On Flanges be used:
Slip on flanges are commonly used in various piping systems for specific applications. Here are some situations where slip-on flanges are often preferred:
Low Pressure Systems: Slip on flanges are suitable for low-pressure systems where the pressure requirements are relatively moderate. They are commonly used in applications such as water supply, irrigation, and low-pressure air systems.
Non-Critical Applications: Slip on flanges are often used in non-critical applications where the pipe connections do not require high strength or rigidity. They are commonly employed in industries such as plumbing, HVAC (Heating, Ventilation, and Air Conditioning), and general industrial piping systems.
Easy Installation and Alignment: Slip on flanges are chosen when ease of installation and alignment is a priority. The slip-on design allows the pipe to slide into the flange, simplifying the alignment process. This makes them suitable for applications where quick and straightforward installation is desired.
Cost-Effective Solution: Slip on flanges are generally more cost-effective compared to other flange types, such as weld neck flanges. They require less labor and time for installation, making them a budget-friendly option for certain applications.
Flexibility in Pipe Length Adjustment: Slip on flanges offer flexibility in adjusting the length of the pipe relative to the flange position. Unlike weld neck flanges, they do not have a weld bevel, providing more freedom in pipe length adjustments. This is advantageous when accommodating thermal expansion or contraction of the piping system.
Non-Corrosive Environments: Slip on flanges are often used in non-corrosive environments or applications where corrosion resistance is not a primary concern. In such cases, slip on flanges made from carbon steel or stainless steel can be suitable options.
