Seamless Steel Tubes and Pipes for Boilers
We have been manufacturing boiler steel tubes and pipes used in all fields, mainly power generation boilers, up to the present day, ever since we first started manufacturing seamless steel tubes for boilers for the first time.
Steel tubes and pipes, to be used to respond to these situations, have been a demand to maintain both high quality and high performance. There has also emerged a need for various steel tubes and pipes such as economic steel tubes and specially-shaped steel tubes.
Boiler tubes and pipes require extremely superior quality and a variety of steel grades and dimensions suited to usage situations.
In line with diversifying needs, we are developing new materials and products, and are conducting a wide variety of research and development, including manufacturing process research.
1. Integrated production system
Our boiler tubes and pipes are consistently controlled. Not only from steel-making to tube and pipe-making. In order to ensure the manufacturing of all steel grades, as well as to assure uniform and stable quality, through strict quality control during each process.
Particularly, steel-making processes, from the component mixture to final heat treatment, undergo optimum quality design regarding boiler steel tubes and pipes, by putting years of experience and high engineering process to full use so that products can endure long usage periods of one or two decades.
In order to bring quality design into shape, a new refining method in steel-making is introduced and various manufacturing processes are selected according to dimensions, material properties, and internal and external surface conditions. Seamless steel tubes and pipes are hot manufactured using The plug mill-rolling process, mandrel mill-rolling process, extrusion process, and push bench process.
These hot manufactured tubes are cold finished using cold-drawing and cold-rolling processes that fit the applications and thermal treatments.
2. Quality assurance system
Boiler tubes and pipes are strongly demanded in order to satisfy especially strict usage conditions, along with operational reliability. We conduct strict quality control in all processes, from steel-making to tube and pipe-making, and we have established the following quality assurance system.
① Independence of the quality assurance department
The quality assurance department is independent from the manufacturing department and has primary authority and responsibility concerning quality in order, to take charge of ensuring such quality.
② Standardization of tasks
Various tasks related to manufacturing and quality are standardized and documented for unification.
③ Adoption of a inspector qualification system
All inspections engaged in work affecting quality have received strict training and have passed a qualification test.
④ Full adoption of nondestructive tests
Various required tests and inspections are conducted according to applications, and nondestructive tests are applied to all products in the final inspection.
Supply Range of Seamless pipes for Power Generation
Our seamless pipes for power generation have been used the world over, embodying various characteristic products through distinguished engineering process and abundant experience, and they have earned a high reputation and trust not only in domestic but also overseas.
The demand for electricity around the world is increasing, and the market for power plant components is becoming increasingly competitive. With some of the most reliable tubing in the market, We can give you that competitive edge to stand out.
