Stainless steel shaped pipes are pipes with special shapes machined on the surface of stainless steel materials,
It has excellent anti-corrosion performance and beautiful surface, and is often used in industries such as construction, chemical, food, and medicine.
It is important to evaluate the surface quality of stainless steel shaped pipes to ensure production quality and usage effectiveness,
The following will elaborate on surface flatness, dimensional accuracy, surface smoothness, surface corrosiveness, and surface detection.
1、 Surface flatness
Surface flatness refers to the degree of contact between the surface of a stainless steel irregular tube and another flat surface, which is the degree of adaptability of the surface geometry.
When evaluating the surface of stainless steel irregular pipes, it is usually necessary to use a straight edge or length measuring instrument to detect the flatness of the pipe surface and determine the radius or immersion length of its flat surface.
2、 Dimensional accuracy
The accuracy of stainless steel shaped pipes refers to whether the size parameters such as diameter, falvastagság, hossz, and ovality meet the design requirements.
In the production process, it is necessary to conduct precision testing on the processing equipment, materials, and errors brought about during the production process.
For dimensional accuracy, the commonly used testing equipment is digital calipers and related measuring instruments.
3、 Surface finish
Surface smoothness refers to the flatness and brightness of the surface of stainless steel shaped pipes, usually judged by mirror finish or roughness.
The surface finish of stainless steel shaped pipes requires not only bright light and non whitening, but also no defects such as cracks, oxidation, és rozsda,
Such defects may affect the anti-corrosion performance and aesthetics of pipelines.
The commonly used methods for evaluating surface smoothness include visual inspection and luminometer method.
4、 Surface corrosiveness
Stainless steel shaped pipes have good corrosion resistance, so it is particularly important to evaluate the degree of corrosion on the surface of stainless steel shaped pipes.
The detection methods, indicators, and standards for surface corrosion are also important issues.
The general method is to apply a corrosive agent to the surface of stainless steel shaped pipes and observe the degree of corrosion.
5、 Surface inspection
Surface inspection is a comprehensive evaluation method for various surface parameters of stainless steel shaped pipes.
Generally, instruments such as microscopes and optical projectors are used to evaluate the geometric shape, roughness, and micro defects of the surface of irregular tubes,
Analyze the type and degree of defects and develop repair measures.
