Custom Manufactured Flanges for Chemical Equipment

Openex recently manufactured a batch of custom flanges for a chemical customer, and more than the flanges were well received by the customer.

The flanges are made of 20mm thick 316L stainless steel with diameters of 1.3m, 1.8m, and 2.1m respectively. The manufacturing of the flanges needs the following steps: grinding, waterjet cutting, welding, shaping, machining, etc. The customer has high requirements on the indicators such as shape and precision. Through this cooperation, the customer deeply appreciated our processing capacity and quality control and indicated that they would preferentially choose to cooperate with us for similar orders in the future.

What are custom flanges?

Custom flanges are flanges that are designed and manufactured according to specific requirements or specifications, rather than being off-the-shelf or standard products. Custom flanges are often used in applications where standard flanges are not suitable due to factors such as size, shape, or material requirements.

There are many reasons why a custom flange may be required, such as to meet specific dimensional requirements, to match a non-standard piping or valve connection, or to work with an existing piece of equipment. Custom flanges can also be used to improve performance, reduce maintenance, and increase safety in specific applications.

Custom flanges can be manufactured from a variety of materials, including carbon steel, stainless steel, alloy steel, and other metals, as well as plastics and composite materials. They can be designed to match specific pressure and temperature ratings, as well as to accommodate various types of gaskets, bolts, and sealing systems.
