Real life, our contact for plastic section tube very much, mainly because of its using range is very wide, brought great convenience to our life.
As applied to more and more people, plastic section tube on the market more and more, we should be how to choose the good quality plastic section tube?
Today everybody together to learn to identify fake plastic section tube method, respectively, as follows:
( A) And inferior section tube surface often have piping phenomenon, this is because the groove wear make up the defect of uneven of irregular appearance. Because and inferior steel manufacturers to the pursuit of profit, often present groove rolling the overweight.
（ 2) And inferior pipe appearance is easy to produce cracks, why is it blank is adobe, adobe air, adobe in the process of cooling due to the effect of thermal stress, cracks, after rolling there is crack.
（ 3) And inferior section tube without metallic luster, reddish or similar to the color of the pig iron, the main reason is the rolling temperature, temperature of steel is through visual inspection, so can't according to the rules of austenite region to stop rolling, the performance of the steel natural can't up to standard.
（ 4) And inferior pipe cross section of the oval, reason is the factory in order to save materials, quantity of the scrap roll before 2 slants big, the strength of this product open drop greatly, but also does not fit the dimensions of specification.
（ 5) And inferior special pipe material with impurity, more steel small density, size and out-of-tolerance is serious, so in the absence of a vernier caliper, can stop weighing check for it.
（ 6) And inferior pipes easily folded, also is the appearance of all sorts of line, this kind of defect often runs throughout the entire product longitudinal. Produce folding reason is due to the pursuit of the false and inferior, high efficiency, large reduction, handle, when the next rolling produce folding, folding products will be cracking after bending, strength descent.
（ 7) Prone to scarring and inferior section tube appearance, there are two reasons, one is false and inferior steel material not average, impurities; 2 it is false and inferior materials manufacturers to rough guide device, easy to stick steel, these impurities after the roll bite are prone to scarring.
（ Eight) And inferior pipe transverse reinforcement and low, often present the phenomenon of discontent, the reason is the manufacturer to reach big minus tolerance, waste quantity of the previous way slants big, small iron type, groove filling.
