How to evaluate the surface quality of stainless steel shaped pipes?

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, ary matetika ampiasaina amin'ny indostria toy ny fanorenana, simika, sakafo, ary fanafody.

Zava-dehibe ny fanombanana ny kalitaon'ny vy tsy misy vy miendrika sodina mba hiantohana ny kalitaon'ny famokarana sy ny fahombiazan'ny fampiasana,

Ity manaraka ity dia hanazava ny fisaka ambonin'ny tany, fahitsiana dimensional, hamandoana ambonin'ny tany, surface corrosiveness, ary ny fisavana ambonin'ny tany.

1、 fisaka ambonin'ny tany

Ny fisaka ambonin'ny tany dia manondro ny haavon'ny fifandraisana eo amin'ny tampon'ny fantsona tsy ara-dalàna vy tsy misy vy sy ny fisaka hafa, 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, hatevin'ny rindrina, NY FAHARETANY, and ovality meet the design requirements.

In the production process, ilaina ny manao fitiliana mazava tsara amin'ny fitaovana fanodinana, Fitaovana, sy ny lesoka nitranga nandritra ny dingana famokarana.

Ho an'ny fahamarinan'ny dimensional, Ny fitaovana fitiliana fampiasa matetika dia calipers nomerika sy fitaovana fandrefesana mifandraika amin'izany.

3、 Famaranana ambonin'ny tany

Surface smoothness dia manondro ny fisaka sy ny famirapiratan'ny ambonin'ny Stainless vy miendrika fantsona, matetika no tsaraina amin`ny fitaratra vita na roughness.

Ny faran'ny etỳ ambonin'ny Stainless vy miendrika sodina dia tsy mitaky hazavana mamirapiratra sy tsy Whitening, but also no defects such as cracks, oxidation, and rust,

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.

Raha fintinina, the evaluation of the surface quality of stainless steel shaped pipes requires a comprehensive evaluation of multiple indicators. Vigorously promoting suitable inspection methods, indicators, and standards is a necessary means to ensure their production, use, and quality.
