Seamless steel pipe has a widely application in each field.

Steel has two types,Use and History of Seamless Steel Pipe Articles one is seamless, and the other is slotted - i.e. there is a single weld along its length. Both have different purposes. Seamless is so widely used. General purpose seamless most, mainly used by ordinary carbon steel, low-alloy structural steel or alloy steel rolling production transporting fluids or structural components. Seamless special purpose boiler seamless pipe, seamless pipe and petroleum geology seamless pipe and other.

Seamless generally more light weight, thinner walls. They used bicycles and transport of liquid. Pipe joints heavier, more rigid. There is a better consistency and are usually straight. They are used for a variety of pipeline transportation, such as natural gas transportation, electricity pipes and other pipelines. Typically, they are not under high pressure, in the instance when the tube used, can be controlled during production - Several characteristics of the tube. For example, the diameter of the pipe is usually modified depending on how to use. Diameter can range from tiny pipes used to make hypodermic needles, for large pipeline transportation of natural gas throughout the city. The wall thickness of the tube can be controlled. Strength and flexibility types of steel tubes usually also have some impact. This can be controlled features include length, coating materials, and ultimate success.

Although the pipe flow is developed, need seamless metal tubes cause. Seamless those who do not weld. They first made by a solid cylinder drill a hole in the center. This method is developed in the late 19th century. These types of pipes are perfect for bicycle frames, because they have a thin wall, is lightweight, but very strong. Founded in 1895, the first factory producing seamless steel tubes. Bicycle manufacturing gave way to the car manufacturers still need gasoline and oil pipelines seamless steel pipe. This demand for greater greater oil reserves are found - Back in 1840, ironworker been able to produce seamless steel tubes.

In one method, a hole is drilled through the solid metal, the round billet. Billet reheating, and through the development of a series of elongated mold to form a pipeline. This method is inefficient, because the center is difficult to drill holes. This leads to non-uniform conduit, the one side thicker than the other. In 1888, an improved method has been patented. In this process, fire brick around the solid core of the casting nozzle. When it is cooled, remove the brick left a hole in the middle. Since then, new technology has replaced roll these methods.
