Here Landee Pipe Fitting offers six tips for the identification method of fake thick-walled seamless pipe.
1. Fake thick-walled seamless steel tube is easy to fold. Folding is the lines formed on the surface of the thick wall seamless steel tube. This kind of defect is often throughout the entire product longitudinal. The cause of fold is the pursuit of high efficiency and large production. When the product is crushed, folding will appear. The folded products will crack easily after bending and the strength of the large thick wall seamless steel tube will be reduced.
2. The appearance of fake thick wall seamless steel tube piping is usually dotted with defects. Pits were caused by groove wear which lead to the irregular uneven defect of thick wall seamless steel tube surface. Due to manufacturer of false thick-walled seamless steel tube pursuing the profit, the crush is often appearing to be outnumbered.
3. Fake thick-walled seamless steel tube surface are prone to be scarring. There are two reasons: first, the thick wall seamless steel tube material is uneven with impurities; second, fake material manufacturer is ill equipped, so the product is easy to stick steel, leading to impurities and scarring.
4. Fake material is easy to generation surface crack for the reason that it performs body is adobe and adobe has lot of hole. When adobe is in the process of cooling, due to the effect of thermal stress, it will generate cracks after crushing.
5. Fake thick wall seamless steel tube is easy to scratch and the reason is that fake product manufacturer is ill equipped and the product is easy to produce burr, reducing the strength of thick-walled seamless steel tube.
6. Fake thick-walled seamless steel pipe has no metallic luster and is appears to be reddish or similar to the color of the iron. There are two reasons: first, the body is adobe; second, fake material has no standard temperature and their steel temperature observing through visual inspection, so the performance of the thick wall seamless steel tube nature cannot be up to standard.
