What are difference between one piece flanges and vanstone flanges
One piece flanges features are as follows:
1. easy and convenient installation, only need to butt the flange with the flange on the other side of the pipe.
2. It is suitable for the scenario of smaller pressure and shorter pipeline, generally used in water supply and air-conditioning systems, etc.
3. the sealing of the single flange connection depends on the gasket, and attention needs to be paid to the selection of suitable gasket material to ensure the sealing.
Van stone flanges characteristics are as follows:
1. Installation is more complicated, need to assemble the flange, flange gasket and bolt together on both sides of the pipe.
2. It can be applied to high pressure, high temperature, long distance transport and other scenes, such as chemical industry, electric power and other fields.
3. the sealing of double flange connection is better, because there are two flanges connecting with each other, so it can be sealed by metal gasket or corrugated gasket etc.
What are difference between one piece flanges and double flanges?
A plastic one-piece flange is a single solid piece made of plastic material such as PVC, CPVC or other thermoplastics.
It is designed to provide safe, leak-proof connections to plastic piping systems, with the advantages of corrosion resistance and chemical compatibility.
One-piece design ensures a strong and durable connection for a variety of industrial and commercial applications involving plastic pipes.
Plastic vanstone flanges for plastic pipes consist of a loose flange ring and a support flange, both made of plastic material.
Place the loose flange ring over the plastic pipe end, then slide the support flange over the loose flange ring and attach it to the pipe using a suitable plastic welding or joining method.
This design allows for easy installation and maintenance of plastic piping systems and the ability to disassemble and reassemble connections without damaging the pipes.
How to choose plastic one piece flange and plastic vanstone flange?
1,Easy installation. The two flanges of double-piece flange can be installed separately, and only one flange needs to be replaced when replacing, without dismantling the whole piping system.
2. Good sealing. As there is a gasket connection between the double flanges, it can form a better sealing effect between the two flanges and is not easy to leak.
3. Long service life. Double piece flanges can be used for a long time in the piping system, quick connection and disassembly, without replacing the whole system.
One piece flanges are suitable for occasions where connection does not require frequent disassembly, such as food, beverage, chemical industry and other fields, and require relatively low sealing.
Vanstone flanges are suitable for occasions that require frequent disassembly, such as petrochemical, water treatment, air-conditioning systems and other fields, and require higher sealing and safety performance.
