Stainless Seamless Steel Pipe Inox Cold Rolled Seamless Precision
Steel Tubes
Description:
Stainless steel precision pipe wall thickness is even, the exterior
inner wall is smooth, no silk road, high precision, tolerance
control range is good.
Stainless steel precision tube characteristics
Dimension accuracy: for the outer diameter below 51mm, the
tolerance of wall thickness and outer diameter is controlled within
the range of + 0.05mm, for the outer diameter above 51mm, and for
the wall thickness and outer diameter within the range of + 0.08mm.
Straightness: if the outer diameter is less than 32, the
straightness is < 1mm/m; if the outer diameter is more than 32,
the straightness is < 1.2mm/ m.
General precision rolling, the whole if about 6 meters of pipe,
straight.
As for our production factory, if there are special requirements,
we must communicate with us before purchasing stainless steel
precision tubes. For orders with higher straitness requirements, we
must conduct trial production, and then carry out small batches,
and finally start mass production.
