An overview of Seamless Pipes: Manufacturing, Benefits, Applications

Seamless pipes are one of the essential elements in a construction or industrial project dealing with fluids. These pipes utilize a billet or long steel cylinder Seamless pipe for their manufacturing. As their name suggests, these pipes do not have any welds and feature a seamless surface. These pipes undergo a perforation process using solid round steel. If you are unsure about seamless pipes, their benefits, and applications, experts at Doshi Impex India, a leading seamless pipe manufacturer, and stainless steel pipe fittings manufacturer in India, have curated this guide offering an overview of seamless pipes.

Manufacturing of seamless pipes

Seamless steel pipe manufacturing involves the following steps:

1. Heating a cylindrical steel billet or piece.
2. Using a mandrel for perforation and passing it through the cylinder.
3. Rolling for increasing length and acquiring desired size, length, shape, and wall thickness.

Classification of seamless pipes based on different manufacturing aspects

Seamless pipes are available in multiple types depending on their manufacturing process. These are as follows:

• Cold-rolled seamless steel pipes
• Hot-rolled seamless steel pipes
• Extruded seamless pipes
• Cold-drawn pipes

Classification of seamless pipes based on different sizes

Seamless pipe have a diameter range from 4mm to 900. A reputed pipes and tube supplier like Doshi Impex India offers an extensive range of hydraulic pipes and tubes for multiple projects. Depending on their diameter, these pipes as further categorized as:

• Thick wall seamless pipe
• Thin wall seamless pipe

Application of seamless pipe

Seamless pipes made of stainless steel find the primary application in the oil and gas industry. Given their seamless nature, they are utilized for drilling petroleum and are as popular as geological drilling steel pipes.

The petrochemical sector utilizes these pipes as cracking pipes. Seamless steel pipes also find applications in multiple industries as structural pipes in the aviation, automobile, and tractor manufacturing industry. They also find applications in boilers.

According to their application, a reputed stainless steel seamless pipe manufacturer like Doshi Impex India offers the following types of seamless pipes:

General-purpose pipes

These stainless steel seamless pipes undergo a rolling process. They are made of low alloy steel, carbon steel, etc. These structural pipes find applications in pipelines and as structural support for processes involving fluid transport.

Pipes as per applications

These are primarily available in three types as follows:

• Seamless steel pipes as per mechanical (physical) properties and chemical composition
• Seamless steel pipes as per pressure ranges. A reputed seamless pipes manufacturer subjects these hydraulic pipes to hydraulic testing depending on their pressure ratings, ensuring their high quality and robustness.
• Seamless steel pipes are customized for special purposes, per applications for different sectors like chemical power, electricity generation, geological sector, industrial boilers, and petroleum extraction.

Seamless steel pipes: Benefits

• Carbon steel seamless pipes, as its name, are devoid of weld joints. Their manufacturing involves using single metal pipes. These pipes do not require any joining components attached via welding.
• These pipes are robust and offer optimal sealing in comparison to welded pipes. Do not fail at the weld location.
• Seamless pipes handle high-pressure ranges. They can take 80% more pressure in comparison to welded pipes.
• These pipes offer better aesthetics with their smooth no-joint construction.
• These pipes do not require additional testing for weld integrity tests from a pipe manufacturer and do not require welding during manufacturing.
• These hydraulic pipes do not require heat treatment or annealing processes, as they tend to harden without any external processes.
• They are a better option for welded pipes. However, welded pipes cannot substitute for seamless steel pipes, given their high structural integrity and strength.
• These pipes offer high corrosion resistance than welded pipes. As these pipes do not undergo additional welding or treatments, they are free of external impurities that strengthen their properties.
• These pipes have high malleability and minimal manufacturing defects.

Final thoughts

Seamless steel pipes are essential for high-precision applications. Thus, purchasing these pipes from a reputed seamless pipe and stainless steel pipe fittings supplier like Doshi Impex India is crucial.
