Stainless steel seamless tube:
Seamless tube is the round tube ingot, through cold rolling, cold
drawing or hot extrusion production process. As the seamless tube
is made of round tube steel ingot processing, so the precision of
the steel tube is low, the wall thickness is not uniform, the
brightness of the inner surface is low, the cost of size is
increased, and after many times of heating, the inner surface is
very easy to have black spots, and it is not easy to remove.
And the steel composition of the production of seamless pipe is
only to meet the basic requirements of ASTM, in the welding process
will produce a variety of unstable factors, not easy to weld and
weld impenetrable. Seamless pipe will also appear metal
delamination, residual stress and so on. The price of seamless pipe
is higher than that of welded pipe.
Precision stainless steel tube:
The precision stainless steel tube is welded by the steel belt
after crimping forming by the unit and the mold, and the welded
tube avoids multiple heating processing in the processing process,
and the production process is more environmentally friendly and
safer. Due to the use of processed stainless steel strip as raw
material, so the production of precision tube with high precision,
uniform wall thickness, high brightness inside the outer surface,
and can be customized according to customer demand.
And the precision tube is formed by precisely grinding the
precision machine coil steel after micro-finishing, so its
thickness tolerance is smaller. With the same chemical composition,
the steel used to make precision tubes has a chemical composition
suitable for welding, so its strength is relatively higher.
Precision stainless steel welded pipe has the advantages of uniform
wall thickness, low residual stress, high welding strength, good
consistency and so on.
Not only that, the quality of precision stainless steel tube is
better than the comprehensive quality of stainless steel seamless
tube, but the market price is only half of the seamless tube.
