Seamless Pipe

Product Description                                                        

Seamless pipe is made from a round steel billet (solid cylindrical hunk of steel that is cast from raw steel). This billet is then heated, stretched out, and pushed or pulled over a form. It is then pierced through the center with a die and mandrel which increases the inside diameter and reduces the outside diameter. Even though seamless pipes are manufactured in a variety of sizes, with an increase in pipe diameter the production cost increases. The name seamless comes from its absence of a seam. Seamless pipes are widely used in process piping, power piping, shipbuilding, pressure vessel, construction, and chemical industries.Seamless pipe, as the name suggests, is a pipe without aseam or a weld -joint. Seamless Steel Pipe is made from asolid round steel "billet’ which is heated and pushed orpulled over a form until the steel is shaped into a hollowpipe. The hollow pipe is then extruded through a die andmandrel combination to reduce the outside diameter and toexpand the inside diameter.Seamless pipe is a tubular section or hollow cylinder,usually but not necessarily of circular cross-section, used mainly to convey substances can flow-liquids and gases(fluids),slurries,powders and masses of small solids.

Seamless tubes are typically more light weight, and have thinner walls. They are used for bicycles and transporting liquids. Certainpipe characteristics can be controlled during production For example, the diameter of the pipe is often modified depending how itwill be used. The diameter can range from tiny pipes used to make hypodermic needes, to large pipes used to transport gasthroughout a city. The wall thickness of the pipe can also be controlled Often the type of steel will also have an impact on pipe'sstrength and flexibility, Other controllable characteristics include leneth coatine material and end finish.

Characteristics/Features

1. Seamless pipe is thought to be able to withstand higher pressure, higher temperatures, higher mechanical stress and acorrosive atmosphere.

2. Hollow pipe is far stiffer per unit weight than solid members.

3. High precision can do small batch production.

4. Smaller diameter.

5. Weldability strong, high compression capability

6. Steel pipe superior perfomance, relatively dense metal

7. Steel Cross area is more complex

8. High precision cold drawn products, good surface quality.

9. The thicker the wall thickness of the solution, it is really more cost effective and wise, the thinner the wall thickness, and its

processing costs ill appreciate sharply.

10. From the process of the product determines its limitations, from the general seamless steel pipe with low accuracy: wallthickness uneven, low brightnes tube appearance, fixed length of high cost, and piting in the appearance of black spots isdifficult to bring go;

11. Seamless steel pipe pressure and hydrostatic test is for pressure tube by into the hydrostatic test, which do not maintain theprescribed pressure value not less than 5 seconds, not to discose, the regular supply hydraulic pressure test is 2.45MPapressure The pressure test is P= 0 5MPa.

12.The corrosion test: industrial corrosion -resistant steel pipe according to standard regulations or agreement between thecorrosion of steel pipe corrosion resistance test, no intergranular corrosion.13. Seamless Pipes can be cold-drawn or hot rolled. Cold-drawn special-section seamless pipes are widely applied in theindustries of petrochemical, boiler, automobile, mechanical, construction.

Advantages of Seamless Pipe

1. lncreased Pressure Ratings. Welded seam of steel pipe is the weakest link However, since the seamless steel pipe has notbeen welded, it does not have seams, making it equally strong around the entire circumference of the pipe.2. Uniformity of Shape particularly on heavy wall sections and a lack of weld seams and increased structural integrity

3. Strength Under Loads

4. There is greater ability to use multi -hole dies for diameter sizes that are smaller. This will decrease cost and increaseproductivity, There's also better control of wall thickness.

Applications of Seamless Pipe
