Frequently Asked Questions (FAQs）
What is a plate flange used for?
Plate flanges are commonly used to connect pipes, valves, and other equipment in low-pressure applications. They provide a flat, strong connection that can be easily assembled and disassembled, making them ideal for industries like water treatment, oil and gas, and HVAC systems.
What materials are your plate flanges made from?
Our plate flanges are typically made from (Duplex) stainless steel including 304, 304L, 316L, 2507, 2205, TP310S, TP321
How are plate flanges installed?
Plate flanges are installed by welding them to the end of a pipe, then bolting them to another flange or piece of equipment. The flat surface of the flange ensures a tight seal, and gaskets are often used to enhance the seal between flanges.
