High pressure flange

High pressure flange: flange for piping or equipment that is used for pressure above 10MPa. At present, it mainly includes traditional high pressure flange and high pressure self-tightening flange.

The high pressure flange is mainly used in the installation of pipeline. The high voltage flange connection is an important connection mode of pipeline construction, and the connection between the main pipe and the pipe plays an important role and value. High pressure flange connection is the two pipes, fittings or equipment, fixed on a flange, a first between the two flange, and flange pad, bolt fastening together, complete the connection. Some pipe fittings and equipment already own flanges, also belong to flange connection.

High voltage flange product performance:

1, abrasion resistance, ceramic composite steel pipe lined with porcelain layer of Al2O3 content is more than , micro hardness HV1000-1500, and therefore has a very high wear resistance, its wear resistance more than 10 times higher than the medium carbon steel after quenching and is better than that of tungsten carbide drill.

2, the corrosion resistance of ceramics is a neutral material, stable chemical performance, excellent corrosion resistance and acid resistance, can resist various inorganic acid, organic acid, organic solvents, such as its resistance to corrosion is stainless steel is more than ten times.

In the process of installation of high pressure flange, to ensure that the installed flange is not leaking oil, what to pay attention to when installing, the following flange factory will help you to interpret

The flanges that are first manufactured should be strong enough that they are not deformed when fastening. Flanges cover should be flat and clean, and the oil and rust stains should be carefully cleaned when installed.

Second, farlane wants the sealing gasket to be equipped with good oil resistance and anti-aging properties, and good elasticity and mechanical strength. The installation should be arranged according to the shape of the connection and the sealing gasket of different sections and sizes.

Below are the technical requirements: the technical requirements of flanges should conform to GB/T 9124. The pressure of flanges at different temperatures shall conform to the provisions of GB/T 9124-2000 appendix A (standard appendix). Flange welding joint type and groove size shall be in accordance with the provisions of GB/T 9124-2000 appendix B (the appendix of the tip).

In the process of use of high pressure flange, the common faults have the change of erosion, temperature, pressure vibration, etc., which brings us to different degrees of leakage problem. If it is a harmful object, it can be harmful to our life. In the event of flange leak problem, timely repair, avoid because of the different medium erosion, make the leakage situation more and more serious, not only caused the loss of material, also brought the destruction of the effective to production environment. These are all issues that we need to pay attention to.

In general, when we were in free throws type selection, through high pressure flange and for different ways of using welding flange, and it can bring us the choose and buy of product effect, increase the quality of our product performance, but we inevitably, the flange of the regular maintenance and repair, these days, if the flange of the leakage problems, no longer need to replace the sealing element and honey respectively. The current polymer composite materials can be directly used to plug the leak in the field, and provide us with good technological operation technology, which is easier and easier to operate, and has a low cost rate.
