    Taiwan seamless steel tube manufacturer – stainless steel & special alloys

 

Seamless steel tube manufactured by centrifugal casting

When it comes to the manufacturing process of seamless steel tubes, maybe you will think of extruded tubes first.  Today, we would like to introduce another technique to produce seamless steel tubes.  And this method is centrifugal casting.

There is without the limitation for manufacturing the seamless steel tubes by centrifugal casting.  All our seamless steel tubes are customized.  The range of diameter is 50~600mm.  The min. thickness is 4.5mm and the max. length is 4,000mm.

 

The common materials of seamless steel tubes manufactured by extrusion is 304, 316 and duplex stainless steel 2205 & 2507.  However, there is a wide range of materials of centrifugal casting.  In addition to the materials mentioned above, all 300 stainless steel series, duplex stainless steel, bi-metal alloys, heat-resistant alloys ( Including HK40, HP, HU…etc), 17-4PH and superalloy (Ex: Incoloy 800H) are able to be manufactured at our foundry.

Heat-resistant seamless steel tube

Heat-resistant steel was designed for casting specification, therefore centrifugal casting is the wise choice to produce the heat-resistant seamless steel tubes.

It is not easy to purchase heat-resistant seamless steel tubes with lager diameter in Taiwan.  Most users import heat-resistant seamless steel tubes produced by extrusion method.  The prices are high and small quantity order is not possible.

However,  the heat-resistant seamless steel tubes produced by centrifugal casting are able to be customized by individual demands. The quantity is able to be small and this advantage is good for customers to decrease the cost and the burden of stock.  

The radiant tubes used in heat-treating plants are heat-resistant seamless steel tubes manufactured by centrifugal casting.  We have a long history for producing and developing radiant tubes and most our radiant tubes are exported to Europe, America, Japan and some countries of southeastern Asia because they have larger demands of radiant tubes than the needs in Taiwan.

Yet, more and more Taiwanese customers need the local radiant tube manufacturer because the domestic demands are getting higher.  They inquired our radiant tubes via internet or recommendation by others and they were surprised at our capability for the production of various radiant tubes. 

The quality and stability of our radiant tubes are impressing because of the fruitful experience we have gained when working with foreign customers in the past.

Superalloy seamless steel tube

Incoloy 800H is the material we have been developing these years and this material is also the seamless steel tube we applied for the subsidy from our local government.

The clients who work in petrochemical plants would use superalloy seamless steel tubes mainly because Inconel 800H seamless steel tube is the material of the reformer tubes in the plants. For those plants, supplying the superalloy seamless steel tubes from us directly is a good news because they will save much cost.

 

So far, we have developed the length 2,000 mm Incoloy 800H seamless steel tube successfully and we are changing some parameters to improve the dimensions and stability.

 

The development of superalloy seamless steel tubes at our foundry not only shows our current capability but also gives customers better choice of heat-resistant material.

We hope our high grade seamless steel tubes will satisfy the domestic demands and export worldwide soon!
