Stub end

Stub end, also known as flange adapters, are a type of pipe flange connection fitting. They have two ends: a fixed end and a floating end. The floating end is used to connect to another flange, thereby achieving a pipe connection. These standards ensure the stability and reliability of the Stub end in different application scenarios. We are a professional manufacturer of Stub End, and we support color customization, size customization, OEM, ODM, and other additional services.

1. The product is made from PE100 virgin material, which has a higher purity and performance, resulting in flange heads with better corrosion resistance, anti-aging properties, high strength, and good toughness.
2. The Stub end is manufactured using advanced production technology, with strict control over every step of the production process to ensure stable and reliable product quality. The Stub end has undergone rigorous testing, and all performance indicators meet national standards, even exceeding some of them.
3. One end of the Stub end uses heat fusion welding technology to integrate the pipe and fittings into a single unit, creating a seamless connection that eliminates the issue of water leakage due to poor sealing.
4. The Stub end has a durable welded connection with a long service life. The welded connection does not suffer from issues such as aging cracks, and its service life can reach over 50 years.
