Champak Steel & Engg. Co is the leading manufacturer of the SS 304/304L/304H Pipes & Tubes. However, we are supplying and exporting the pipes and tubes to the clients available around the globe. We are also considered among the well-known stockist and importer of the wide ranges of pipes and tubes. The pipes and tubes are available in different specifications as per the expectations of the clients. Specifications like surface finish, end finish, dimensions, shapes, sizes, length, and toughness are there.
Pipes and tubes available are interchangeably used in industrial applications. The best way that the industries are distributing fluids among the applications is with the help of the tubular section of the pipes. This is the best to supply all the gas and the fluids which are available. The pipe is the hollow sections which are used in the applications with the round cross-sections that convey the products easily. The dimensions and the diameter of the pipe are noted according to the application in which it is used.
Apart from this, the tubes are the pressure equipment that is used in industrial applications. The tubes and pipes are available in many shapes and sizes. Some of the shapes in which the pipes and tubes are available are round, square, rectangle that is having the hollow sections. And the basic difference among the pipes and tubes comes in the wall thickness, material, end connections, and others.
The SS 304 alloy steel is used in the development of the pipe and tubes. However, the alloy is made up of chromium and nickel contents which are providing the pipes and tubes various properties. In addition to this, the SS 304L is the low carbon content than the 304 alloy steel. This is the way that it is good at having the intergranular corrosion resistance ability. In the same way, the SS 304H is the high-temperature application used alloy which is there with the high-temperature strength and the ability to work in the elevated temperatures.
The alloy is the reason that the SS 304/304L/304H Pipes & Tubes are having different properties. Some of the properties which the pipes and tubes are having are corrosion resistance, great ductility, durability, stability in the elevated temperatures, and great toughness.
