Classification of stainless steel decorative tube

Release time:


Stainless Steel Decorative TubeThere are many kinds of, but the main have the following uses:

1Classification by production method:

(1)Seamless pipe--Cold drawn pipe, extruded pipe, cold rolled pipe.

(2)welded pipe:

(a)Classification by process--Gas shielded welded pipe, arc welded pipe, resistance welded pipe(High frequency, low frequency).

(b)By weld--Straight seam welded pipe, spiral welded pipe.

2Classification by section shape:(1)circular steel pipe;(2)Rectangular tube.

3Classification by wall thickness--Thin-walled steel pipe, thick-walled steel pipe

4Classification by Purpose:(1)Civil pipe sub-circular tube, rectangular tube, flower tube, generally used in decoration, construction, structure and other aspects;

(2)Industrial pipe:Steel pipe for industrial piping, steel pipe for general piping(Potable Water Pipe)Mechanical structure/Fluid delivery pipe, boiler heat exchange pipe, food hygiene pipe, etc. Generally used in various fields of industry such:Petrochemical, paper, nuclear energy, food, beverage, pharmaceutical and other industries have higher requirements for fluid media.

2.Stainless Steel Decorative Tubeseamless steel pipe

Stainless steel seamless pipe is a long steel with a hollow cross-section and no seams around.

1.Manufacturing Process and Flow of Seamless Steel Pipe:

Smelting>steel ingot>steel rolling>Sawing>Peeling>Perforation>Annealing>Pickling>On the ash>cold drawn>Cut head>Pickling>Receipt

2.Characteristics of seamless steel pipe:

From the above process we are not difficult to see:First, the thicker the wall thickness of the product,The more economical and practical it is,The thinner the wall thickness,Its processing costs will rise significantly.;Secondly, the process of the product determines its limitations, the general seamless steel pipe precision is low.:Uneven wall thickness, low brightness inside and outside the tube, high cost of sizing, and pitting and black spots inside and outside the tube are not easy to remove.;Third, its detection and shaping must be processed offline. Therefore, it reflects its superiority in terms of high pressure, high strength and mechanical structure materials.

3.Stainless Steel Decorative Tubewelded steel pipe

Welded steel pipe is referred to as welded pipe, which is made of stainless steel pipe welded by steel plate or steel strip after crimping and forming unit and mold.

2.Characteristics of welded steel pipe:

From the above process we are not difficult to see:First, the product is a continuous online production.,The thicker the wall thickness,The greater the investment in units and dissolving equipment.,The less economical and practical it is. The thinner the wall thickness,Its input-output ratio will fall accordingly.;Secondly, the process of the product determines its advantages and disadvantages. Generally, the welded steel pipe has high precision, uniform wall thickness, high brightness inside and outside the stainless steel pipe fittings, and can be arbitrarily fixed.
