    Taiwan seamless tube manufacturer

 

(seamless tubes manufactured by centrifugal casting)

 

Seamless tube made in Taiwan

Most people know the seamless tube is formed by extrusion, however our seamless tube is manufactured by centrifugal casting technique.

Due to the huge investment for making extruded seamless tube, no one would like to establish a company focusing on manufacturing seamless tube in Taiwan.  So, we are only able to import seamless tubes from other countries now.

 

The common material of seamless tube with small diameter (smaller than 50mm) is SS 304.  However, it is difficult to purchase seamless tube with larger diameter in Taiwan even the common stainless steel.

Until today, the petrochemical plants still need to import the larger diameter seamless tube with special heat-resistant material or they purchase the stainless steel 316 or 310 to replace the old tubes.

 

One of the advantages of centrifugal casting technique is the seamless tube by centrifugal casting is without the limitations of materials and dimensions.

We are able to manufacture both smaller and larger diameter seamless tubes.

Not only common stainless steel (For example, 304, 316 …etc), but also heat-resistant alloys (HK, HP…etc) and superalloys are able to be produced by centrifugal casting technique.

 

Heat-resistant seamless tube manufactured in Taiwan

There are the large demands of heat-resistant seamless tubes in developed countries since their petrochemical, oil & gas, nuclear and offshore industries have been prosperous development.  So, the technique for producing heat-resistant seamless tubes are more mature compared with us.  However, the larger diameter seamless tubes are used more often in those industries.  Therefore, centrifugal casting technique is used to produce heat-resistant seamless tube with larger diameter instead of extrusion technique.  It is because the extruding method is not suitable for producing seamless tube with larger diameter.  

 

LAWAI has manufactured heat-resistant seamless tube by centrifugal casting for a quite long time.  The seamless tubes are supplied to both heat-treatment and petrochemical plants.  HK 40, HH, HP, HP MOD …etc are the common heat-resistant materials we produce often.

Through the industrial upgrade of the petrochemical plants, we have developed the superalloy seamless tube for higher requirements to resist creep.

 

 

 

 

Superalloy Incoloy 800H seamless tube

There are only two corporations producing superalloy bars and sheets in Taiwan.  For superalloy seamless tubes, LAWAI is the only company to produce that.

Incoloy 800H seamless tube is one of the superalloy seamless tubes we developed successfully.  The Incoloy 800H seamless tubes are applied in reformers of petrochemical plants in Taiwan.  Once the local petrochemical plants purchase our superalloy seamless tubes, they will save much cost and they do not need to have large stock.  LAWAI supplies the superalloy seamless tubes to them, it will decrease the purchasing cost and risk.

In order to follow the international steps of the development of the superalloy seamless tubes, we are planning to develop other superalloy seamless tubes.

 

Exporting superalloy seamless tubes is our next goal.  We hope our superalloy seamless tubes manufactured by centrifugal casting will be top 3 centrifugally cast products made by us!
