The waterproof function and role of the stub end in stainless steel pipe fittings in pipeline applications

2024-08-15

The stub end in stainless steel pipe fittings is a connecting material commonly used in the fields of construction and engineering. It adopts a stamping process and uses the function of the mold on the flat or curved part of the blank to form a straight wall or stub end with a fixed angle along the edge of a closed or unclosed curve.It has excellent corrosion resistance and strength, and is also widely used in waterproof systems. In terms of waterproof performance, stainless steel stub end show excellent characteristics.

High sealing performance

The production process of stainless steel stub end is very delicate, and the contact parts are specially treated to ensure the sealing performance of the joints. When the two joints are connected to each other, the stainless steel stub end structure can provide a better sealing effect and effectively prevent moisture penetration. This makes the stainless steel stub end joint have good reliability in the waterproof system.

Strong corrosion resistance

The stainless steel stub end joint is made of stainless steel material and has excellent corrosion resistance. Stainless steel materials can resist the erosion of various chemicals, making stainless steel stub end have a longer service life in humid environments. This corrosion resistance makes stainless steel stub end an ideal waterproof solution.

Strong pressure resistance

Stainless steel stub end have excellent pressure resistance and can withstand physical pressure. Whether it is the load of the building structure or the extrusion of external forces, stainless steel stub end can maintain their integrity without deformation or damage. This makes stainless steel stub end a waterproof material in various construction projects.

Wide adaptability

Stainless steel stub end can adapt to pipes, equipment and components of various shapes and sizes, and can be used in conjunction with other waterproofing systems. Whether it is roof waterproofing, basement waterproofing or ground waterproofing, stainless steel stub end can play a good role. Stainless steel stub end can also be used in conjunction with other materials, such as rubber sealing rings, to provide better waterproofing effects.

1. The center positions of the two ends are different

The center points of the two ends of the stainless steel eccentric reducer are not on the same axis.

The center points of the two ends of the stainless steel concentric reducer are on the same axis.

2. Different operating environments

One side of the stainless steel eccentric reducer is flat. This design facilitates exhaust or liquid drainage and facilitates maintenance. Therefore, it is generally used for horizontal liquid pipelines.

The center of the stainless steel concentric reducer is on a line, which is conducive to fluid flow and has less interference with the flow pattern of the fluid during diameter reduction. Therefore, it is generally used for diameter reduction of gas or vertical liquid pipelines.

3. Different installation methods

Stainless steel eccentric reducers are characterized by simple structure, easy manufacturing and use, and can meet a variety of pipeline connection needs. Its application scenarios mainly include:

Horizontal pipe connection: Since the center points of the two ends of the stainless steel eccentric reducer are not on the same horizontal line, it is suitable for the connection of horizontal pipes, especially when the pipe diameter needs to be changed.

Pump inlet and regulating valve installation: The top flat installation and bottom flat installation of the stainless steel eccentric reducer are suitable for the installation of the pump inlet and regulating valve respectively, which is beneficial to exhaust and discharge.

Stainless steel concentric reducers are characterized by less interference to fluid flow and are suitable for reducing the diameter of gas or vertical liquid pipelines. Its application scenarios mainly include:

Gas or vertical liquid pipeline connection: Since the center of the two ends of the stainless steel concentric reducer is on the same axis, it is suitable for the connection of gas or vertical liquid pipelines, especially where diameter reduction is required.

Ensure the stability of fluid flow: The stainless steel concentric reducer has little interference with the fluid flow pattern during the diameter reduction process and can ensure the stability of the fluid flow.

4. Selection of eccentric reducers and concentric reducers in practical applications

In actual applications, appropriate reducers should be selected according to the specific conditions and needs of pipeline connections. If you need to connect horizontal pipes and change the pipe diameter, choose stainless steel eccentric reducers; if you need to connect gas or vertical liquid pipes and change the diameter, choose stainless steel concentric reducers.
