What should be paid attention to when sealing the wear-resistant steel plate
The pressure test of the wear-resistant steel plate can ensure that its shape can remain as it is, which can be selected according to the properties of the wear-resistant steel plate. When the wear-resistant steel plate is sealed, it is better to choose a better sealing material, because the sealing needs to ensure the wear resistance of the material on the edge. And it is best to sprinkle a layer of polymer, which can ensure the quality of the wear-resistant steel plate.
The new end face sealing device adopts high-strength polyurethane sealing material. Due to the application of electro-hydraulic proportional control technology, it can maintain proper sealing force and protect the sealing ring. This kind of sealing ring has a long service life, is more convenient to install, and greatly reduces the dead zone of the pressure test. Radial sealing method The radial sealing rubber ring of the test head is inside the wear-resistant steel plate.
In order to achieve the internal pressure and the wear-resistant steel plate wall contact seal, the sealing ring has a long service life, is more convenient to install, and greatly reduces the labor intensity, but the shortcomings of the wear-resistant steel plate pressure test have blind spots. A typical composite steel-lined tubing liner has a matrix of fiber-reinforced polymers that protect the steel matrix from corrosion. Corrosion of spacer rings, in particular, ensures that the corrosion-resistant lining ends between adjacent ones.

Steel prices have risen by more than a thousand steel companies generally turn losses into profits
Since the first half of last year, steel prices have begun to recover thanks to a series of measures such as supply-side reforms and elimination of backward production capacity. Taking rebar as an example, the average price on March 9 last year was 2475 yuan/ton, and on March 9 this year, it has risen to 3852 yuan/ton, an increase of 35%.
