What are the product characteristics of high pressure flanges?

High-pressure flange product structure: generally composed of cassettes, sleeves, sealing rings, and bolts.

1. Metal sealing ring: The sealing ring is the key part of the high-pressure self-tightening flange, and the cross section is similar to "T". After the flange is assembled, the ribs of the sealing ring are clamped by the two central end faces to form a capillary tube and a whole, which greatly improves the strength of the connection part. The double-arm sealing crack of the T-section, together with the inner cone of the bushing, creates the sealing area and freely extends to the external force (within the yield limit) to form the seal.

2. Shaft sleeve part: After the centers of the two shaft sleeves are fixed by the shaft sleeve, they are pressed on the rib of the sealing ring, and the sealing lip is separated from the inner sealing surface of the shaft sleeve. This deviation allows the load of the inner sealing surface of the belt to flexibly return to the crack of the sealing ring, forming a self-reinforcing elastic seal.

3. Cassette: The cassette can be freely adjusted to 360 directions during installation, which is easy to install.

4. 4 sets of ball bolts Generally speaking, each set of high-pressure self-tightening flange only needs 4 sets of tangential high-pressure ball bolts to complete the overall fastening. High pressure flange

What are the product characteristics of high pressure flanges?

1. Sealing method: The core of the high-pressure self-tightening flange is a unique, new metal seal to metal. That is to say, the seal is formed by the elastic deformation of the seal lip (T-arm) of the seal ring, which is a hard seal. A strong rigid body is formed by the combination of the root bone of the sleeve, the cassette and the sealing ring, so that the strength of the connecting part is much greater than the strength of the pipe base material itself. When under pressure, tendons and lips have their own strength and sealing effect, not only self-sealing, but also strengthening the pipeline, greatly enhancing the overall strength of the joint

2. Tensile: In most cases, the high-pressure self-tightening flange can bear the tensile load more than the pipeline itself during the connection process. The failure test results showed that the flange was still intact after the pipeline could not bear the tensile load.

3. Bending resistance: The batch test results show that the flange will not leak or loosen when subjected to a large bending load. Actual test: The high-pressure self-tightening flange weld of DN15 specification is cold-formed many times in the pipeline, the high-pressure self-tightening flange connection does not leak, and the bolts are not loose.

4. Pressure resistance: In normal pipeline applications, high-pressure self-tightening flanges do not withstand overload compression. When high compressive loads occur, the larger load of the high-pressure self-tightening flange is determined by the ultimate strength of the pipeline. High pressure flange

5. Impact resistance: small geometric volume, can withstand the impact force that traditional high-pressure flanges cannot bear. The unique metal-to-metal seal structure greatly improves impact resistance.

6. Corrosion resistance: The selection of other materials provides corrosion resistance and meets the special anti-corrosion requirements of different use environments.
