Advantage

1. Material:  

All adopt new positive material reel as raw material production, high purity, nickel, chromium, copper and other elements are all up to the national standard.  

Refuse to use the return charge, low purity, unstable composition, easy to rust.  

2. Surface: 

stainless steel tube surface bright no bump, no black spots, no cracks, no pull, completely no trashhole, smooth weld.  

Unqualified stainless steel pipe surface is gray, many places more peeling, there are obvious holes, black spots, cracks, strains, weld uneven.  

3. Precision:  

Stainless steel tube size to ensure high, the outer diameter can be controlled in plus or minus 2 C, wall thickness control in plus or minus 1~2 C, especially customized when the accuracy is higher, especially suitable for tapping teeth, tube kit, core bending and other high requirements of processing.  

Decorative pipe or unqualified product pipe accuracy is poor, the outer diameter tolerance is usually more than plus or minus 20 C, the wall thickness is also jerky is not solid thick, can not be tapping, kit processing and fitting  

4. Processing performance:  

Stainless steel welded pipe extension performance is good, beautiful welding, can flaring, shrinking mouth, pull bending, playing the cone does not crack.  

Unqualified pipe can not be called product pipe, welding is not permeable or too permeable to deep processing, will crack, or weld sag.  

5. Length of stainless steel pipe:  

According to the standard of the industry scale is 6 meters commonly, the error is within + 10 mm, the length of the seamless tube of general uncertain feet more, length is 5 ~ 7 meters is given priority to, according to the requirements of different customers, manufacturing stainless steel pipe can be customized according to the requirements of different length, relative to character, stainless steel welded pipe length can be 3 to 9 m, small influence on production cost.  So the purchase of stainless steel welded pipe customers can be customized according to their own needs of different lengths.  Sizing of seamless tubes may be required, but this may have a significant impact on the cost of production.  

6. Thickness

The thickness of the stainless steel tube is generally produced in accordance with the standard thickness, and the measured value of the thickness within the tolerance range is the actual thickness.  According to the requirements of national standard tube thickness tolerance within ±0.3mm;  In the industry, the thickness tolerance of general decorative pipe is less than 25%, the thickness error of product pipe is within the allowable range of ±0.10mm, and the thickness tolerance of precision pipe is within ±0.05mm.  

Our stainless steel pipe is shown according to the actual thickness, and the price is marked according to the actual thickness (thickness tolerance is 0.03mm) without explanation.
