Management of blind flanges: Could you share the management regulations and specific operating procedures for blind flanges in various factories? Is it production that proposes the use of blind flanges, or is it the process department (during shutdowns)? It was found that blind plates are very difficult to manage. Thank you so much!
The process department is responsible for the blind flanges in the plant area, while the production department is responsible for those in the plant boundaries and between different plants – one handles each area, no confusion!
We are all in charge of processes, mainly ticket management; a signing system is implemented. It’s a bit troublesome, but it ensures proper verification.
We do not distinguish between production and processes; the process workshop responsible for the relevant area proposes them and is in charge of arranging and supervising the maintenance department to carry them out. All procedures are initiated by the process workshop and followed through the appropriate processes.
A meeting must definitely be organized to identify the contacts and document everything; just talking about it isn’t enough. The production management department coordinates with the relevant upstream and downstream workshops, as well as those under systematic management, to decide on how to perform line cleaning and where to install blind flanges And create a detailed explanation table.
The process department is responsible for the blind flanges in the plant area, while the production department is responsible for those in the plant boundaries and between different plants. It’s necessary to identify contacts for each area and document this information!
The removal and installation of blind flanges must be carried out in accordance with established procedures; production is guided by relevant technical specifications, and a list of blind flanges should be prepared as per these specifications, with production supervision and inspection completed accordingly
Process and production are intertwined; as one of the eight high-risk operations, blind plugging must be taken seriously. No matter who raises the issue, the procedures must not be disrupted, and records must be kept. The risk lies in the operation process and the handover records – blind plugging cannot be forgotten
We do the same【the process department is responsible for the blind flanges in the equipment area, while the production department is responsible for those in the equipment boundaries and between different plants.】
