No matter in the whole process of purchase or application, High pressure Sandblasting pipe The quality of must be maintained regularly. In the whole process of inspection, attention must be paid to the following matters.

1. Standard size and specific deviation of high pressure hose:

Because the inner diameter and diameter of the high pressure sandblasting pipe and the diameter of the frame layer all produce shaking, if the shaking force exceeds the allowable limit, the balance of the bending amount of the sandblasting pipe connector cannot be ensured, and the quality of the sandblasting pipe overall cannot be guaranteed. Therefore, for the sandblasting pipe used in the general process of manufacturing sandblasting pipe, it is necessary to strictly check whether the inner diameter and diameter of the frame layer meet the requirements, and the regulations on diameter deviation can be properly released.

2. Wall thickness deviation of high-pressure rubber hose:

Because the part of the vulcanized rubber layer in the high-pressure sandblasting pipe is painful and the damage of the overall width of the rebar lap of the vulcanized rubber layer in the high-pressure sandblasting pipe quality inspection center in the middle of the frame layer, the deviation of the sandblasting pipe wall thickness will be too large. If the wall thickness deviation exceeds the allowable range, it may endanger the airtightness and pull-out compressive strength of the connector, and even cause some inclination (skew head) of the connector of plastic hose parts. Therefore, the wall thickness deviation of the sandblasting pipe should be strictly controlled. Generally, high-pressure hoses with wall thickness deviation exceeding 0.5mm shall be selected smoothly.

3. Adhesion between layers of high pressure hose:

High quality high pressure sand blasting pipe shall have prominent comprehensiveness, that is, the product quality inspection of high pressure sand blasting pipe shall have a high adhesive force in the middle of each solid layer, and the adhesive force in the middle of each adhesive layer shall become comprehensive. Only in this way can we integrate various technical standards in the whole process of connector installation and combination, and only in this way can we ensure the product quality inspection regulations of high pressure sandblasting pipes used in the total process of sandblasting pipes. Therefore, the adhesive force between each layer of the high-pressure hose must not be less than the requirements of the standard specifications, and the high-pressure hose with high adhesive force should be selected as far as possible to produce high-pressure hose components.

4. Appearance quality of high pressure sandblasting pipe:

High pressure sand blasting pipe The appearance quality should not be ignored. It not only endangers the appearance quality of the product quality inspection of the high pressure sand blasting pipe in the total process of the sand blasting pipe, but also endangers the application quality. If there are bubbles, air holes or mechanical equipment damage on the surface of the vulcanized rubber, the frame layer will be exposed, resulting in erosion of the frame layer, reducing the tensile strength of the rubber sandblasting pipe, immediately endangering the service life of the rubber sandblasting pipe components, and even leading to safety accidents in use. Therefore, attention should be paid to the appearance quality of the sandblasting pipe. According to the quality inspection of the high-pressure sandblasting pipe, the appearance defects that endanger the overall function of the sandblasting pipe should be removed. High pressure sand blasting pipe has wide application coverage.
