Overview of 316L Stainless Steel Tubing
Yasco 316L stainless steel industrial pipes are engineered for superior performance in demanding environments. Made from a high-quality austenitic stainless steel alloy containing 16% chromium, 10% nickel, and 2% molybdenum, these pipes offer exceptional corrosion resistance, particularly against chlorides and acidic substances.
Inspection Methods for 316L Stainless Steel Pipes
1.Appearance inspection
The surface should be smooth without scratches, pits, oxide layers or rust spots, and the two ends of the cut should be flat without burrs.
The weld area needs to be inspected for defects such as cracks and pores, and the surface color should be uniform and consistent.
2.Dimensional measurement
Use tools such as calipers and micrometers to measure parameters such as outer diameter, wall thickness, and length to ensure compliance with national standards or contractual requirements.
Precision pipes need to be checked for ovality and straightness deviation.
3.Mechanical performance testing
Detect tensile strength (≥ 485MPa), yield strength (≥ 170MPa), and elongation (≥ 40%) through tensile testing.
Impact test verification of low-temperature toughness (applicable to special purpose pipes) 2.
4. Chemical composition testing
Use a direct reading spectrometer or handheld XRF device to determine the content of key elements (such as Cr: 16.5-18.5%, Ni：10-14%，Mo： 2-3%), ensuring compliance with 316L standard 24.
5. Chemical reagent testing
Special identification solution (such as copper sulfate or 316L detection solution) is dropped onto the surface to determine the authenticity of the material through color changes.
6.Non destructive testing
Ultrasonic testing (UT) or eddy current testing (ET) is used to detect internal cracks, inclusions, and other defects.
Metallographic analysis: Observe grain size, inclusion distribution, and uniformity of austenite structure under a microscope.

Attention
1.Avoid Chloride Exposure: While 316 stainless steel offers excellent corrosion resistance, prolonged exposure to high concentrations of chlorides (e.g., seawater or salt solutions) can cause pitting or crevice corrosion. Ensure proper material selection for such environments.
2.Avoid Galvanic Corrosion: When connecting 316 pipes with dissimilar metals, ensure proper insulation to prevent galvanic corrosion caused by electrochemical reactions.
3.Welding Precautions: Use low-carbon 316L stainless steel filler materials during welding to prevent carbide precipitation and maintain corrosion resistance in welded areas.
