Flanges are integral parts of many engineering and plumbing projects. Used in many, different fields, such as the transport (pipelines, ships) of petroleum, gas, water, etc., their manufacturing facilities and those of power generation, chemicals, and chemical fertilizers, flanges are of various kinds in type and shape, and their material too is diversified (low carbon steel, low alloy steel, stainless steel, high alloy steel, non-ferrous steel, or such) in accordance with the type of fluid and service environment.
In many applications, engineers need to find a way to close off a chamber or cylinder in a very secure fashion, usually because the substance inside must differ from the substance outside in composition or pressure. They do this by fastening two pieces of metal or other material together with a circle of bolts on a lip. This “lip” is a flange.
You can connect two sections of metal piping by soldering or welding them together, but pipes connected in this way are very susceptible to bursting at high pressures. A way of connecting two sections of pipe more securely is by having flanged ends that you can connect with bolts. This way, even if gases or liquids build up to high pressures inside the pipe, it will often hold with no problem.

At forging stage, We control the temperature, check the size, then put them into the heat treatment furnace. Inspect the mechanical property, size. After that, we start machining,
Check the dimension again. Do nondestructive inspection to make sure no crack inside.
Drill holes, marking, final inspection, packing.
We continuously pursue perfect product, more science and technology contents and higher quality, more advanced technology design, more considerate service to satisfy our customers and thus win the market together.
