Lap Joint Flange For Sale
The primary function of lap joint flanges is to allow easy alignment and assembly of pipelines. They are particularly useful in situations where frequent disassembly and reassembly of the piping system are required. This type of flange allows the pipe to slide through the flange, which simplifies the installation and maintenance process.
Shenghe lap joint flange provides high flexibility. Due to the unique design, our lap joint flanges provide rotational adjustability, which enables easy alignment of bolt holes during installation. It is especially beneficial in applications where there might be thermal expansion or vibration, as it allows the pipe to move independently of the flange.
Contact us for our extensive range of lap joint flange sizes and materials available to suit your specific requirements.
Long Welding Neck Flange For Sale
A long welding neck flange is a specific type of flange commonly used in piping systems that require a strong and secure connection. The primary function of a long welding neck flange is to connect two pipes or fittings together. It acts as a connecting point, creating a seal between the piping components and ensuring the integrity of the system.
Shenghe long welding neck flange has excellent strength and resilience. The extended neck of the flange adds extra stability and reduces stress concentration, making it ideal for piping systems that undergo significant pressure or temperature fluctuations.
This type of Shenghe flange is specifically designed for high-pressure and high-temperature applications, where a durable and reliable connection is essential. If you are in need of a long welding neck flange for your piping system, we at Shenghe offer a comprehensive selection of high-quality flanges to meet your specific requirements.
Orifice Flange For Sale
An orifice flange is designed to hold an orifice plate in place, which creates a restriction in the flow path of the fluid. This restriction leads to a pressure drop across the orifice plate, allowing for precise measurement of the fluid flow rate.
Shenghe orifice flanges provide a reliable and accurate means of measuring fluid flow in a piping system. The orifice plate installed within the flange has a precisely machined hole and is positioned in such a way that it creates a differential pressure across the plate as the fluid passes through it. This pressure difference can be measured and used to calculate the flow rate using established flow equations.
Reach out to us to learn more about our orifice flange solutions.
Plate Flange For Sale
Plate flanges are a versatile and essential component used in various industries for connecting pipes or valves to different types of equipment. These flanges are flat circular disks with evenly spaced bolt holes around the perimeter.
Shenghe plate flanges provide excellent strength and stability, ensuring a reliable and secure connection. The flat surface provides increased stability and distributes forces evenly, reducing the risk of leakage. They are commonly used to create a termination point, enabling easy access and maintenance of the piping system.

Shenghe socket weld flanges provide a smooth bore and offer excellent flow performance, making them ideal for high-pressure and high-temperature applications. Contact us to discuss your specific requirements.
Spectacle Blind Flange For Sale
A spectacle blind flange, also known as a figure-8 blind flange, is a specialized type of flange that serves a crucial function in piping systems. It is specifically designed to isolate sections of a pipeline, providing a positive and visible indication of the line’s status. By inserting the solid disc into the flange, it creates a physical barrier to prevent flow, making it an ideal choice for maintenance, repairs, or when there is a need to change process flow.
The presence of the Shenghe spectacle blind flange ensures the safety of personnel working on the pipeline. Its highly visible design provides clear visual indication and prevents accidental opening, reducing the risk of injury or damage to the system.
Let us help you find the perfect spectacle blind flange solution for your piping system needs.

Notes:
Dimensions are in millimeters unless otherwise indicated.
D = Hole size (where required) should be the same as the flange bolt hole. In practice, these dimensions have been rounded round off upwards.
W = Thickness of the web (or tie bar) should be 6 mm minimum, or equal to Thickness (t) if less than 6 mm.
Spectacle Blinds should be made from a plate or forging specification, approved for use by ASME B31.3, of essentially the same chemical composition as the mating flanges and piping involved.
Spectacle Blinds ASME B16.48 may be used for installation between ASME B16.5 flanges.
Depending on a customer specification, some dimensions can be different from what on this page is defined.
