To guarantee that the cast iron drainage covers meets the standards that the customer and the manufacturer have set, we do laboratory test. Since this test is a part of the quality control stage, we conduct it at the very end, after the drainage covers have been manufactured. There are a number of laboratory tests that we commonly perform on drainage covers. This is the complete discussion.
1. Load Test
To find out whether an object can endure a specific load pressure, we do a load test. The load test is an area of destructive testing.
Static loading tests, in which an object is stationary and does not change its direction of intensity or work line, are frequently used to test cast iron drainage covers, such as manhole covers and gratings.
2. Metallography Test
We do metallography tests to examine a metal’s microstructure and properties. The findings of this metallographic test will be used as a guide to assess whether the substance utilized complies with the necessary requirements.
3. Hardness Test
To find out whether a drainage cover material can endure indentation or penetration loads, we do a hardness test. Knowing the material’s hardness is important since the drainage covers will undergo friction and plastic deformation when in use.
Types of hardness tests:
- Rockwell Hardness Manual
- Rockwell Hardness Digital
- Portable Hardness (Brinell)
- Micro Vickers Hardness
4. Composition Test
A composition test is a laboratory test used to determine the element content of a drainage cover material. It’s objective is to determine the value of the material’s constituent elements, such as the essential elements Fe, C, Mn, Si, Ni, V, and others. We use a spectrometer machine to do the composition test.
5. Tensile Strength Test
Tensile strength testing is a technique for determining the strength of a material by applying an axial static force slowly or fast. The tensile strength test results in the mechanical properties of the drainage covers material in the form of strength and elasticity.
6. Ultrasonic Test
The ultrasonic test is a method for detecting defects that arise within the product. This test can also estimate the defect’s magnitude and location. The ultrasound test is performed by infusing ultrasound (high frequency and short wave) into the product and detecting internal defects with refractive characteristics and wave alterations in the interface.
This ultrasonic test is included in non-destructive testing so that the product’s shape and qualities do not change.
These are the six laboratory tests that are typically performed on Infiniferro cast iron drainage covers. By performing this test, we ensure that the quality of the drainage covers you receive meets the requirements you specified.
