What are the product characteristics of high-pressure flanges?

High pressure flange product structure: generally composed of clamp tape, sleeve, sealing ring, and bolts.
1. Metal sealing ring: The sealing ring is a key part of the high-pressure self tightening flange, with a cross section similar to "T". After flange assembly, the ribs of the sealing ring are clamped by two sets of central end faces, forming a capillary tube and a whole, greatly improving the strength of the connecting part. The double arm sealing crack with a T-shaped section, together with the inner cone of the shaft sleeve, creates a sealing area and freely extends to an external force (within the yield limit) to form a seal.

2. Shaft sleeve part: After the centers of the two shaft sleeves are fixed by the shaft sleeves, they are pressed against the ribs of the sealing ring, and the sealing lip disengages from the internal sealing surface of the shaft sleeve. This deviation allows the load on the inner sealing surface of the strap to flexibly return to the cracks in the sealing ring, forming a self reinforcing elastic seal.
3. Clip: The clip can be freely adjusted to 360 degrees during installation, making installation convenient.
4. Generally speaking, each set of high-pressure self tightening flange requires only four sets of tangential high-pressure spherical bolts to complete the overall tightening. High pressure flange
What are the product characteristics of high-pressure flanges?
1. Sealing method: The core of high-pressure self-tightening flange is a unique new metal seal to metal. In other words, a seal is formed by the elastic deformation of the sealing lip (T-shaped arm) of the sealing ring, which belongs to a hard seal. The combination of the root and bone of the sleeve, cassette, and sealing ring forms a strong rigid body, making the strength of the connecting part greatly greater than the strength of the pipe base material itself. When subjected to pressure, the tendons and lips each have a strength and sealing effect, which not only seals themselves, but also strengthens the pipes, greatly enhancing the overall strength of the joints
2. Tension: In most cases, high-pressure self tightening flanges are more capable of withstanding tensile loads during connection than the pipe itself. The damage test results show that the flange is still intact after the pipe cannot withstand tensile load.
3. Bending resistance: Batch test results show that this flange will not leak or loosen when subjected to large bending loads. Actual test: The high-pressure self-tightening flange welds in the DN15 specification have been repeatedly cold bent in the pipeline, and the high-pressure self-tightening flange connections are not leaking, 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 pressure shrinkage loads occur, the larger load on the high-pressure self tightening flange is determined by the ultimate strength of the pipeline. High pressure flange
5. Impact resistance: small geometric volume, capable of withstanding impact forces that traditional high-pressure flanges cannot withstand. The unique metal to metal sealing structure greatly improves impact resistance.
6. Corrosion resistance: The selection of other materials provides corrosion resistance to meet the special corrosion protection requirements of different use environments.
