详情描述

Quick-opening blind flanges are mechanical devices used on circular openings of pressure pipes or pressure vessels. They typically consist of components such as cylinder flanges, head covers, hooks or clamps, sealing rings, safety interlock mechanisms, opening and closing mechanisms, swing arms, and stubs (as required).

Quick-opening blank flanges are a type of quick-opening cover for pressure vessels, widely used on equipment in the natural gas field that requires frequent opening and closing. Common quick-opening blank flanges are divided into typical structures such as tooth-type, clamp-type, bayonet-type, locking ring-type, expanding ring-type, and fixed pressure ring-type, primarily operated manually.

Our quick-opening blind flange is designed according to ASME VIII Div.1, with finite element stress analysis and structure performed by ANSYS. All major pressure components are machined from solid forgings, utilizing low-alloy high-strength carbon steel.

Corrosion-resistant surfacing process, suitable for various operating conditions, and capable of undergoing hydrogen and sulfur resistance tests.

Our quick-opening blind plate fully complies with regulations such as GB150 and adheres to the industry standard SY/T0556-2018 (Technical Specification for Quick-Opening Blind Plates).
