Steel pipe inspection services include:
Thickness testing, eddy current testing, corrosion testing, quality testing, roundness testing, corrosion testing, dimensional testing, flaw detection, nondestructive testing, and impact strength testing.

Physical and Chemical Property Inspections
1. Chemical Composition Inspection: This primarily checks whether the carbon, sulfur, and phosphorus content of the steel pipes meet standard requirements.
2. Mechanical properties test: including tensile strength, yield strength, impact toughness, etc. These indicators are directly related to the service life and safety performance of steel pipes.
3. Weld performance inspection: Welding is one of the important processes of steel pipes. It is very important to inspect the strength and reliability of the welds. Generally, weld tensile and bending tests are used.
4. Corrosion performance and wear resistance test: These indicators are mainly used to evaluate the corrosion resistance and wear resistance of steel pipes under specific environmental conditions.

Appearance and Geometric Dimension Inspection
1. Surface Inspection: This primarily checks the surface quality of the steel pipe for defects such as cracks, scars, and bubbles.
2. Dimension inspection: Check whether the outer diameter, wall thickness, length and other parameters of the steel pipe meet the requirements, and also check the straightness and curvature of the steel pipe.
3. Appearance inspection: Check whether the appearance quality and shape of the steel pipe meet the standard requirements.
