QHS type pipeline coating scratch depth measuring instrument
The QHS type pipeline coating scratch depth measuring instrument is designed and manufactured according to the requirements of SY/T 4113-2007 "Scratch resistance test method for anti-corrosion coatings" standard. The QHS type pipeline coating scratch depth measuring instrument has a simple structure and easy operation, and is suitable for measuring the depth of pipeline coating scratches in the laboratory.
Technical parameters of QHS type pipeline coating scratch depth measuring instrument:
1. Micrometer range: 0mm to 1mm; Accuracy: 0.001mm
2. Height of micrometer lifting: 0mm to 100mm
3. Laboratory coating sample specification: 100mm × 100mm × (≥) 6mm
4. Specification of pipe section sample: 100mm × 50mmm × (≥) 3mm
5. Measurement thickness: 0mm~1mm
6. Chassis size: 225mm × 200mm
The main structure of QHS type pipeline coating scratch depth measuring instrument is:
The measuring instrument mainly consists of a dial gauge, a card head, a column, a column locking handle, a bracket, an internal hexagonal cylindrical head screw, a base plate, etc.
Working principle of QHS type pipeline coating scratch depth measuring instrument:
The sample is placed on the floor, and the distance between the coating surface of the pipeline sample and the bottom of the scratch is measured using a micrometer probe to determine the depth of the pipeline coating scratch.
Usage method of QHS pipeline coating scratch depth measuring instrument:
1. Prepare the test sample
a、 According to Article 4.2 of SY/T4113-2007 standard, prepare three pieces for laboratory coating test, and make three scratches on each piece.
b、 Alternatively, according to Article 4.3 of SY/T4113-2007 standard, prepare nine pipe section specimens and scratch each specimen.
2. The tested sample shall comply with the provisions of Article 5 and Article 6 of SY/T4113-2007 standard.
3. Adjust the measuring rod of the dial indicator to be vertical to the upper plane of the base plate. The method is to loosen the two hexagon socket head cap screws properly, observe the verticality of the measuring rod with naked eyes from the front and side of the dial indicator, and then adjust the dial indicator back and forth, and turn the dial indicator left and right according to the specific situation to achieve its verticality. After vertical adjustment, lock the two hexagon socket head cap screws respectively (Note: Before using the measuring instrument, check the verticality of the measuring rod of the dial indicator and the base plate to ensure the accuracy of the test results).
4. To adjust the zero point of the measuring instrument, the method is to remove the loose coating on the surface of the tested sample, and then place the sample on the bottom plate of the measuring instrument produced by Tianjin Huayin Instrument, with the coating surface facing up. Adjust the height of the dial gauge appropriately according to the sample situation, and lock it in place with the column locking handle. Then move the sample and place the dial gauge probe in the undamaged area on one side of the measuring point. Adjust the scale of the dial gauge to 0 millimeters.
5. Lift the measuring head steadily and move the measuring point of the scratch on the test sample (note: the middle point of the scratch and two points 25mm on each side from the middle point are the measuring points) to the bottom of the measuring head, then lower the measuring head and ensure that the bottom of the measuring head falls into the bottom of the scratch.
6. Record the scratch depth of each measurement point and the average depth of all scratches.
7. Repeat steps 4 to 6 above to measure the scratch depth of the remaining samples.
The scratch depth is expressed as the average measurement of nine scratch depths, with the scratch depth accurate to 0.01mm.
