201 stainless steel decorative Pipe & Tube

201 stainless steel decorative tube is also called stainless steel welded steel pipe referred to as 201 welded pipe,commonly used in steel or steel strip after the unit and the mold coil forming after welding made of steel.

201 welding steel pipe production process is simple, the production efficiency is high, the variety of specifications, equipment and less capital, but the general strength is lower than the seamless steel pipe. But 201 in the construction of a very wide range of decorative. And the production process is simple, high efficiency, low price.

Allowed wall thickness tolerance

Level Wall tolerance allowed
D1 +-1.5%,Min +-0.75mm
D2 +-1.0%,Min +-0.50mm
D3 +-0.75%,Min +-0.30mm
D4 +-0.50%,Min +-0.10mm

Calculating formula for weight(KG/M)

(Outdais meter-wall thickness)×wall thickness}×0.02491=KG/M

Production process of SS decoration round pipe

We have our own processing factory, production machines, skilled workers. Short production cycle, high efficiency, high product quality.Division,our company have 201,304,316L and other conventional goods,delivery time is short.For the majority of customers is a good choice.Also,we can process No.4,HL,Mirror finish etc by our machine according to customers requirements.
  • Prepare the original material: stainless steel sheet/strip
  • Slit the original material: stainless steel sheet/strip
  • Use the machine to rolled into tube type
  • Then fused by rolled machine
  • Finish treatment:Bright heat treatment
  • Both inside and outside the weld process
  • The shape of the pipe
  • Now were up in the big leagues getting turn
  • Important processing:Fixed outside diameter
  • eddy current testing
  • Laser diameter measurement
  • Pickling process
  • Finished: Storage

Treatment for finish

No.4 finish:

Honed with 150-180 grit abrasive belt products. It has better brightness with discontinuous coarse grain,

fine stripes than NO.3. Stainless steel castings used for sanding and polishing the surface.

HL finsih:

Polishing abrasive belt with a suitable size (150 to 320 mesh), so No.4 generates continuous hairline brushed surface.

Mirror finish

We call it No.8 finish.Rotary buff polishing, mirror-like surface of the polishing surface.

Application for stainless steel decorative pipe & Tube

The use of decorative tube is very wide.Such as Stainless steel window, stainless steel railing, stainless steel stair railing, interior design, etc.The main purpose is used for indoor and outdoor decoration.
