Recent accidents are all related to flange maintenance. Is there any special management for flanges?

This post was last edited by Shutong on 2022-6-25 23:40 Flange is a connecting component that plays an important role in ensuring the sealing between pressure pipelines, valves and various types of equipment. Combined with the pressure pipeline construction of the PAETEkF module, the control measures for the tightness of flange installation are explained.: It mainly includes material control, quality control in the welding process and quality control in connection and assembly. Only through reasonable selection of materials, correct installation, implementation of standards and specifications, and safe operation can the safe and stable long-term operation of the production device be ensured. In fact, large companies should have systems for flange management. High-pressure flanges and hydrogen-facing flanges are especially top priority. Many leaks and explosions are caused by poor management. PetroChina pays special attention to this, and the well-managed company constructs a flange seal management data warehouse and conducts OLAP analysis. There are some PetroChina systems below for reference, which have been uploaded to the forum. Management rules for flange gaskets and fasteners 9. Management regulations for the use of flange protective covers. 2. Management methods for flange joints. 18

Very detailed, thank you. Flange management is the management of the entire process, from design, installation, procurement, maintenance, etc.

If winning the bid at a low price is not resolved, safety accidents will inevitably occur.

This time I bid for a pipeline bid, but I won the bid with the lowest price. The user department recognized my product, but the owner's purchasing department only bought the lowest price.

The most basic things are the easiest to overlook. None of our plans had basic technical requirements, or were simply wrong. The installation units are all subcontracted. On this basis, there will be no problems. There is always a level in our minds that nothing will happen, and there is no solution to the level of nothing can happen. After analyzing this, you will understand that it is normal for something to happen.
