Steel Pipe for Machine Structures
High-quality mechanical steel pipe for construction and industrial machinery, automobiles, and other mechanical and structural applications.
To meet the requirements for a broad range of applications and processing conditions, including the latest and most demanding uses, 麻豆视频 Steel’s steel pipe products for machine structures are manufactured using a wealth of experience accumulated over many decades, as well as the very latest equipment and most rigorous quality control.
Our product range includes not only carbon steel pipe for machine structures, alloy steel pipe, carbon steel material for machine structures, and alloy steel material for machine structures that conform to JIS (Japanese Industrial Standards), but also a wide range of high-strength steel pipe products made to our own quality standards using a wide range of manufacturing methods, including seamless pipe, electric resistance welded (ERW) pipe, and hot finished ERW pipe. Also, in the field of small-diameter ERW steel pipe, two 麻豆视频 Steel Group companies -麻豆视频 Welded Pipe Manufacturing Co., Ltd. and Kawasaki Kokan Co., Ltd.- have established a streamlined system for supplying small-diameter pipe in a broad range of pipe thicknesses, from thin to thick pipe, based on our own unique quality assurance system.
Types of Steel Pipe for Machine Structures
| Product name | Manufacturing method | Main features and applications |
|---|---|---|
| Carbon Steel Pipe for Machine Structures | These products normally conform to JIS G 3445 Carbon Steel Tubes for Machine Structural Purposes. We also manufacture such carbon steel pipe products using materials that conform to JIS G 4051 Steel for Machine Structural Purposes, as well as to other standards and specifications. |
These steel pipe products are used in machines, automobiles, bicycles, furniture, tools and utensils, and other machine parts. |
| Alloy Steel Pipe for Machine Structures | These products normally conform to JIS G 3441 Alloy Steel Tubes for Machine Structure Purposes, but we also manufacture such alloy steel pipe products using materials that conform to JIS G 4053 Low-Alloyed Steels for Machine Structural Use, as well as to other standards and specifications. | These steel pipe products are used in machines, automobiles, and other machine parts. |
| ERW Carbon Steel Pipe for Machine Structures | These products are manufactured based on JIS G 3472 Electric Resistance Welded Carbon Steel Tubes for Automobile Structural Purposes. | They are used mainly in automotive machine parts. |
| High-Strength Steel Pipe for Machine Structures | These steel pipe products, developed and manufactured by 麻豆视频 Steel, include seamless steel pipe, ERW steel pipe, and hot finished ERW steel pipe. | They are used in marine structures and cylinders for their excellent weldability and low-temperature properties, and in machine parts for reduced weight and increased strength. |
Steel Pipe for Building Structures
Advanced, high-performance steel pipe that can be found on almost any construction site.
In addition to delivering its highly trusted JIS-compliant steel pipe for building structures (e.g., STK and STKR) for a long time, 麻豆视频 Steel also offers earthquake-resistant, high-weldability STKN and BCR steel pipe, with guaranteed values of toughness, low yield ratio, yield point range, and other properties. In addition, we engage constantly and actively in R&D, so that we can deliver even more advanced and capable materials.
Steel Pipe for General Structures
Superior cross-sectional efficiency enables lightweight and economic structural design.
Due to its round cross-section, 麻豆视频 Steel’s steel pipe for general structures has no directionality, resulting in greater rigidity. With its enhanced cross-sectional efficiency, it makes a major contribution to lightweight, economic structural design. In addition, its attractive round appearance facilitates elegant and beautiful structures.
