What is the pressure bearing capacity of large flanges?
Release Time:

Large flanges are divided into traditional large flanges and self-tightening large flanges. Traditional large flanges are like butt welding flange products. The sealing effect is the same, and the connection method is the same as other butt welding flanges.
Large flanges refer to pipe or equipment connection flange products with a pressure bearing capacity of more than 10Mpa, and most of them are butt welding flanges. Large flanges are different from large flanges. They are divided into two categories: traditional large flanges and high-pressure self-tightening flanges. Let's understand it from the two types of large flanges and their pressure bearing capacity. The pressure bearing capacity of the large flange is very high, and the small pressure will reach 10Mpa, which is what we call 100 kg pressure. The pressure bearing capacity depends on the relevant large flange specifications and thickness for comprehensive calculation;
Marine flange classification:
Large flanges are divided into traditional large flanges and self-tightening large flanges. Traditional large flanges are like butt welding flange products. The sealing effect is the same, and the connection method is the same as other butt welding flanges. It is connected to the pipe end to connect the pipes to the pipes, and the two flanges are tightly connected together through the stud bolts; the self-tightening large flange is The new seal relies on the elastic deformation of the sealing lip of the sealing ring to form a seal. This is a hard seal that has good sealing performance and can strengthen the pipeline.
First of all, the large flange should have sufficient strength and must not be deformed when fastened. The sealing surface of the flange should be flat and clean, and the oil and rust spots should be carefully cleaned during installation. The large flange connection is easy to use and can withstand greater pressure. In industrial pipelines, flange connections are widely used. In the home, the pipe diameter is small and low pressure, and the flange connection is not visible. If you are in a boiler room or a production site, there are flanged pipes and equipment everywhere. the
The second is that the large flange gasket should have good oil resistance and performance, as well as relatively good elasticity and mechanical strength. For installation, gaskets of different cross-sections and sizes should be selected according to the shape of the joint and placed correctly.
