This large diameter flange is used for pressure vessel. Pressure vessel flange is a common connection part of pressure vessel,and it is the basic component connecting various pressure vessel parts and pipelines. Pressure vessel flange is widely used in petrochemical,electric power,atomic energy,light industry and other modern industrial fields. The flange of high pressure vessel is a set of components,including flange,gasket,matching studs and nuts. The function of flange is to ensure that the connection parts do not leak, so that different vessels or pipes are combined together. Operating principle of pressure vessel flange: the overall sealing performance is the priority factor in the design and selection of vessel flange. When the flange bolts are tightened, the bolt pressure compresses the gasket through the flange ring, and the pressure forces the gasket to produce compression deformation. With the increase of bolt force, the flange sealing surface and sealing gasket are closely combined to prevent the leakage of fluid medium and create the initial sealing environment.

Custom made large diameter flanges can come as large as the customer requires and made to their design specs. Our extensive heavy-duty manufacturing capability combined with a large inventory of plate stock allows us to meet the most complex and challenging quality and delivery requirements. We leverage numerous fabrication methods, including plate burning, CNC and conventional machining, automated flange drilling, robotic welding with automatic positioning, and many other state-of-the-art technologies to produce flanges with precise tolerances and fine surface finishes. Our expertise spans all flange types, including blind and reducing flanges, spectacle and paddle blinds, O-rings and Victaulic rings, adapter rings, and many other custom flanges. We can provide thermal stress relief, die-stamp/etching identification markings, and apply protective coatings, all in-house.
As an ISO compliant manufacturing company, we perform both in-process and final inspections to ensure flange quality. In addition to traditional dimensional measurement equipment, we use high-end laser devices to verify tolerances. We offer non-destructive testing (NDT) on flanges for the most stringent applications to confirm they are defect-free. We provide material traceability and inspection reports to document that our products meet the highest standards of excellence.
