About SS decoration/welded round pipe

Stainless steel decorative tube also called stainless steel welded pipe referred to as welded pipe, 

commonly used in steel or steel strip after the unit and the mold coil forming after welding made 

of steel. 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.


With the rapid development of high-quality strip rolling production and progress of welding and

 testing technology,and constantly improve the weld quality, varieties and specifications of welded 

steel pipe is increasing, and in more and more fields especially in the heat exchanger tube, decorative

 tube, etc. in thelow-pressure fluid pipe instead of the seamless steel tube.

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.


Allowed wall thickness tolerance 

LevelWall thickness 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


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 

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.
