Product Description

Precision steel pipe is the kind of carbon steel , alloy steel or stainless steel pipes with high precision sizes. Usually produced in hot rolling or cold drawn (cold rolling) processes. So precision pipe are seamless pipes, some precision pipes are welded steel pipes.

Precision pipes designed with several advantages:
● Inside and outside surface no any coating;
● Precision tubes could bear high pressure, no leaking;
● Strict less tolerance;
● Surface smoothly
● No reformation in cold bending, no cracks during flaring test and flattening test.

Precision pipes tubes widely used for manufacturing the pneumatic parts and hydraulic components
The internal and external diameter could control within +/- 0.01 mm. In the guarantee of anti-bending strength and torque strength same, the weight of precision pipe is lighter. It can be widely used in manufacturing precision machinery parts and engineering structure, and also commonly used to produce various kinds of conventional weapons, barrel, shells, bearing, conveyor rollers, sugar mills ect.

The highly precise steel pipes & tubes we produced widely used for idler roller manufacturer for many years.

It's really excited to learn that your company also do well in Idler Roller manufacturer, since we also have many other customers doing the same business as yours.
The precise steel pipes produced by us range and tolerance control as below :

Regular production diameter: 101.6mm, 108mm, 127mm, 133.1mm, 152.4mm, 158.8mm, 165.1mm, 177.8mm, 219.1mm etc, also customized sizes available.
Tolerance control :
OD 101.6mm ~ 127mm, On Specified OD Tolerance ±0.1 mm, Ovality 0.2 mm;
OD 133.1mm ~ 219.1mm, On Specified OD Tolerance ±0.15mm, Ovality 0.3 mm;
On wall Thickness :
±0.2 mm for the pipe wall thickness below and include 4.5mm,
±0.28 mm for the pipe wall thickness above 4.5mm.
Straightness :
Shall not exceed 1 in 1000 (measured at the midpoint of the tube).

Production time is normally 20 days, Looking forward your warm reply and inquiries, thank you
