Steel pipes can be disintegrated on the basis of its application. Typical applications of steel pipes are in the area of water pipelines, industrial water lines, oil pipe lines, cross country pipe line, agriculture and irrigation pipes, tube lines for natural gas, chemical industries, automobile industry, construction industries and other purposes.

Seamless steel pipe (SMLS) is formed by drawing a solid billet over a piercing rod to create the hollow shell, without welding or seam. It is suitable for bending and flanging. The most advantage is increasing the ability of withstanding higher pressure. So it is widely used for boiler and pressure vessel, automotive area, oil well, and equipment components.

Seamless piping is required for many high-pressure, high-temperature applications in the oil & gas, power generation and pharmaceutical industries. Welded piping (which is generally cheaper to produce and is more widely available) is specified across all industries as long as the temperature, pressure and other service variables do not exceed parameters noted in the applicable standard.

Type 304 is slightly less strong than 302 due to its lower carbon content. Type 304 is widely used in welding applications because the low carbon allows some exposure in the carbide precipitation range of 800¡ãF – 1500¡ãF without the need for post-annealing operation.

Seamless piping begins as a solid cylindrical hunk of steel called a billet. While still hot, billets are pierced through the center with a mandrel. The next step is rolling and stretching the hollow billet. The billet is precisely rolled and stretched until it meets the length, diameter and wall thickness as specified by the customer order.

Fusion weldability of Type 304l stainless steel is excellent with or without fillers. The recommended filler rod and electrode for use with 304 stainless steel is grade 308 stainless steel. For 304L, the recommended packing is 308L. Heavy welded sections may require post weld annealing. The 304L does not require this step. If post weld heat treatment is not possible, grade 321 can be used.
