Stainless steel seamless tube is a hollow section, no seams around
the strip steel.The wall thickness of the product, the more thick,
it is more economical and practical, the thinner wall thickness,
its processing cost will rise significantly.Decide the limits of
its performance of the product process, generally low precision
seamless steel pipe: low surface brightness, uneven thickness, tube
length cost is high, and the appearance is not easy to remove and
pitting, black spots.Its detection and plastic must offline
processing.So it in high pressure and high strength material,
mechanical structure embodies its superiority.
Standard by GB14975-94《Stainless steel seamless pipe 》Steel pipe is
usually (indefinite feet) hot-rolled steel pipe length 1.5~10m,Hot
extrusion is equal to and greater than steel pipe 1m.Cold drawing
(rolling) steel tube wall thickness 0.5~1.0mm.1.0~7m,Wall thickness
is greater than 1.0mm 1.5~8m.
