熱間押出しによるシームレス鋼管 - シームレス鋼管 - erw パイプ
熱間押し出しによって得られるシームレス鋼管は、作用力が圧縮である製造プロセスの結果です。熱間押し出しでは、鋼ビレットが、マトリックスと呼ばれる特殊なツール上に成形および配置されたいわゆる「パッセージ ライト」に押し込まれ、目的の形状が得られます。このタイプの処理は、必要な力を減らし、室温で処理すると本質的に特に延性がない材料に対してより簡単に操作できるように、高温で行われます。続きを読む -

Seamless steel pipes-ERW Steel Pipe
Seamless steel pipes are produced by piercing a solid billet of steel to form a hollow tube. The billet is heated to a temperature that allows it to be easily pierced by a piercing mill. The mill contains a mandrel, which is a cylindrical tool that supports the inside of the tube during the piercing process.Once the billet is pierced, it is rolled and stretched to achieve the desired shape and size of the tube. This process is known as the extrusion process. The extrusion process can produce seamless pipes of various sizes and thicknesses, making them suitable for a range of applications.The main advantage of seamless pipes is that they have a smooth surface finish, which is essential for industries such as water supply, where cleanliness is crucial. Seamless pipes are also stronger and more durable than welded pipes, making them suitable for applications where high pressure and high temperatures are involved, such as in the oil and gas industry.続きを読む -
how are steel tubes made-Welded Steel Pipe
Steel tube (and Steel Pipe) has evolved over history. Specifically, metal tube has been around since around 3000 BC. In fact, Egyptians made the first metal pipe from copper.As Early as 2500 BC Chinese used bamboo pipe as a way to transport gasAs early as 2500 BC, Chinese used bamboo pipe as a way to transport natural gas to light Peking, their capital. Rome and Persia created aqueducts to bring water to city centers for bathing, washing and drinking.Furthermore, pipe (or tubing) is made with many different materials and methods. Hollowed stone, fired clay, bamboo, palm, redwood, lead, bronze, copper, and rubber are just some of the materials that makeup tubing.In the mid-1800’s the modern steel industry was bolstered with the Bessemer process. The Bessemer process represented the first inexpensive method for mass production of steel pipe. Subsequently, seamless tube was born in 1895. Quickly followed by manufacturing of auto, bicycle, and machinery for oil production which began in full force.続きを読む -
HOW THESE PIPES ARE MADE?-erw carbon steel pipe
Steel pipes are cylindrical steel tubes that are used in the manufacture and infrastructure of several different styles. They are the most used steel industry product. The key use of pipe is in the underground movement of liquid or gas, including oil, gas and water. However in the development and construction process pipes of different sizes are used. The narrow steel pipe that operates the cooling system in refrigerators is a typical example of household development. Building uses heating and plumbing tubing. It is possible to create structures using steel pipes of various sizes like handrails, bike racks or pipe pads.The pioneer of steel pipe fabricators is believed to be William Murdoch. In 1815 he mixed barrels of muskets with a burning system of coal lamps. In his revolutionary piping method, Murdoch used coal gas to be brought to lamps on London’s streets.Since the 1800’s, significant advances have been made in steel pipes technology, including the advancement of production processes, development of applications for their use and the development and qualification of regulations and standards.続きを読む -
lsaw steel pipe-erw carbon steel pipe
High quality steel pipes are produced from three (3) manufacturing processes: Seamless, LSAW (longitudinal-seam submerged arc welding), and ERW (electric resistance welding). LSAW and ERW pipes are highly regarded for their numerous fields of application. They are tremendously used in foundation solutions and systems, marine construction, structural construction, and diverse applications in water projects, petrochemical, chemical, and power industry, agricultural irrigation, urban construction, and more.続きを読む -
How lsaw steel pipe made?-lsaw steel pipe
LSAW steel pipe (Longitudinally Submerged Arc Welding abbreviated as LSAW) is a professional expression term for LSAW steel pipe. It uses a single medium and thick plate as the raw material, and the steel plate is pressed (rolled) into a tube blank in a mold or a forming machine. The pipe is produced by submerged arc welding and expanded diameter.UOE LSAW pipe forming process:The three main forming processes of UOE LSAW steel pipe forming process include: steel plate pre-bending, U forming and O forming. Each process adopts a dedicated forming press to complete the three processes of pre-bending the edge of the steel plate, U forming and O forming in sequence to deform the steel plate into a circular tube.JCOE LSAW pipe forming process:Forming: After several steps of stamping on the JCO forming machine, first half of the steel plate is pressed into a "J" shape, then the other half of the steel plate is pressed into a "J" to form a "C" shape, and finally pressurized from the middle to form An open "O"-shaped tube blank is formed.続きを読む -
