A tube, or tubing, is a long hollow cylinder used for moving fluids (liquids or gases) or to protect electrical or optical cables and wires.. The terms "pipe" and "tube" are almost interchangeable, although minor distinctions exist — generally, a tube has tighter engineering requirements than a pipe.Both pipe and tube imply a level of rigidity and permanence, whereas a hose is usually ...

Boilers play an important role in various types of plants for the power and chemical industry. With the progress of these industries, modern boilers have become larger in size and the temperature, as well as the pressure, has increased. Therefore, the steel pipes used within them must be of a higher quality.

Seamless Tubing. By definition seamless tubes are completely homogenous tubes, the properties of which give seamless tubing more strength, superior corrosion resistance, and the ability to withstand higher pressure than welded tubes. This makes them more suitable in critical applications in harsh environments, but it comes with a price.

How to Identify Seamless or ERW Stainless Steel pipes? To identify that a pipe supplied is seamless or ERW, Simply read the stencil on the side of the pipe. If it is ASTM A53, Type S means seamless. Type F is furnace but welded, Type E is Electrical resist welded. Thats how. It is the easiest way to identify wether pipe is seamless or ERW.

Seamless pipes have a higher price per ton than ERW pipes, generally 20 to 30% higher, due to their fairly complex production process (more articulated than the manufacturing process of ERW and LSAW pipes) and to due to the fact that the number of seamless pipe manufacturers is rather limited (the market has an oligopolistic nature).

What Does Seamless Tube Mean? A seamless tube is a tube that does not have any welding seam. The seamless tube will ideally be a solid metal tube with each end connected to another tube without having any welding joint. These tubes have threads either at one end or at both ends and can be threaded to the end of another hollow tube or pipe.
