Classification and Application of Carbon Steel Seamless Pipe

1, General seamless carbon content

Generally the carbon content of ≤ 0.25% of steel called low-carbon steel, low carbon steel annealing organization for a small amount of ferrite and pearlite, the lower its strength and hardness, ductility and toughness, ease of drawing, stamping, extrusion, forging and welding, which 20Cr steel use more widely. The steel has a certain strength, this steel after quenching and tempering has good mechanical properties, good low temperature impact toughness, temper brittleness is not obvious. Uses: In the

mechanical manufacturing suitable for the manufacture of welded structures and forged, hot stamping and machining parts without high stress in the steam turbine and boiler manufacturing multi-media work for a non-corrosive pipe, flanges, header and various fasteners; also applies to the manufacture of automobiles, tractors and general machinery manufacturing SMEs carburizing, carbonitriding and other parts, such as the hand brake shoe on the car, the lever shaft, gearbox derailleur , the tractor camshaft drive gears and passive suspension balancer shafts, bushings and other internal and external balancer; in heavy, medium machinery manufacturing industry, such as forging or pressing the rod, hook and loop, lever, sleeve and fixtures.

2, Low-carbon steel seamless pipe

Low carbon steel carburizing: low carbon steel carbon content of more than 0.15% by carburizing quenching, tempering after treatment requirements for applications requiring high surface hardness, good wear resistance, shafts, bushings, sprockets, and some plastics molds and other parts. Low-carbon steel by carburizing quenching and tempering to obtain a surface treated for high carbon martensite, the center of a low-carbon martensite, thus ensuring the surface with high hardness, high wear resistance and heart Ministry has very good strength, toughness. Handbrake shoes suitable for the production, the lever shaft, gearbox derailleur, drive a tractor driven gear and camshaft, hanging balancer shaft balancer inside and outside the bushings, sleeves, clamps and other parts.

3, Carbon steel seamless pipe

Carbon steel: carbon content of 0.25% to 0.60% of carbon steel, due to an increase in steel pearlite content, its strength and hardness increase over the previous hardness after quenching can be significantly increased. High strength quenched and tempered carbon steel, has a certain plasticity and toughness, good machinability, using quenching get good mechanical properties, hardenability poor. For the manufacture of high strength requirements, toughness middle parts. Typically used in quenched and tempered or normalized state. In order to make the necessary toughness of steel and eliminate the residual stress should be after quenching and tempering of steel into patenting.

Seamless Steel Pipe – Everything You Wanted to Know About It

The seamless steel pipe is known as stronger alternatives to welded pipe versions for its ability to fuse pipes without any seams. This is ideal for eliminating the problem of pipes that are weaker at the seams.

Advantages of Seamless Steel Pipes

There are many advantages of seamless pipes as compared to those of other pipe varieties. As has been mentioned before, they are much stronger and hence are more reliable especially in harsh working conditions. They are great for performing heavy duty activities in important industry sectors. This steel pipe variety is far more refined than other metal or even steel pipes. Also, they are highly resistant to corrosion and can resist high heat and pressure.

The Making of Seamless Steel Pipe

The first step involved in the making of this pipe is heating solid ingot. A piercing rod is then inserted in this so that you can get a hollow tube, to be used as pipe. Due to this method of production, they are also known as ‘Hot Finish Seamless Pipe’. There are many important techniques involved in completing the finishing process of these kinds of steel pipes. 

Sizes and Shapes of Seamless Steel Pipes

The seamless steel pipe has many different sizes and dimensions .  You can get them in thin to large diameter pipe as per your area of application. You can also get them in solid and hollow variants. While the solid forms are known as rods or bars and are used extensively in construction facilities, the hollow ones known as tubes or pipes are used mostly in the transporting oil and gas etc. Seamless steel pipes & tubes can be purchased in rectangular, square, triangular and round shape as well.

Uses of Seamless Steel Pipe

This pipe finds wide application in various important industry sectors. Though they are expensive compared to their welded counterparts, yet they are preferred for their extremely high performance quotient. Some of the areas where these are used are the aviation sector, aircraft, missiles, anti-friction bearing, ordinance etc. The wall thickness of most of seamless steel pipe range from 1/8 to 26inch outside diameter.
