The Development Prospect of Seamless Steel Pipe is Very Good

Among the many high-quality pipe materials, seamless steel pipe is the most noteworthy one. This type of pipe material not only has a clear market advantage, but also a lot of fields that can be applied. This typical hollow-section pipe material not only transports various fluids, but also serves as a medium for transporting oil and natural gas. Overall, the advantages of this type of pipe material are very obvious, and it is precisely because of this. The market share of seam steel pipes will continue to increase, becoming a pipe material that is both practical and intensive.

From a longer-term perspective, the future development of seamless steel tubes is also very good, because the applicable direction is very wide, so the future development trend of seamless steel tubes is great, not only in many fields. At the same time, the cost performance of seamless steel tubes is also very high. It is because of the advantages of many aspects that this pipeline material can have such high market value and obtain better development opportunities.

Considering from the perspective of the process, the production process of the general seamless steel pipe can be divided into cold drawing and hot rolling. The seamless steel pipe manufacturers in the market are using only these two methods to manufacture. In comparison, the production process of cold-rolled seamless steel pipes is generally more complicated than hot rolling. The annealing process is a very important step. It must be acid-washed with an acidic liquid. If a large amount of foaming occurs during this process, the quality is not up to the corresponding standard.

The raw material of the seamless steel pipe is a round tube blank, and the round tube embryo is cut into a blank having a length of about 1 m by a cutting machine, and sent to a furnace for heating through a conveyor belt. The billet is fed into a furnace and heated to a temperature of approximately 1200 degrees Celsius. The fuel is hydrogen or acetylene. After the round tube blank is released, it is subjected to a through-hole punching machine. After perforation, the round billet is successively rolled, rolled or extruded by three rolls. After extrusion, the tube should be sizing. The sizing machine is rotated at a high speed by a conical drill bit into a steel core to form a steel pipe. The inner diameter of the steel pipe is determined by the outer diameter of the sizing machine drill bit. After the steel pipe has been sized, it enters the cooling tower and is cooled by water spray. After the steel pipe is cooled, it is straightened. After the steel pipe is straightened, it is sent to a metal flaw detector (or water pressure test) by a conveyor belt for internal flaw detection. If there are cracks inside the steel pipe, bubbles and other problems will be detected. After the quality inspection of the steel pipe, it must be carefully selected by hand. After the quality inspection of the steel pipe, the paint is sprayed with the number, specification, production batch number, etc., and is hoisted into the warehouse by the crane.

The appearance of cold-rolled seamless steel pipe is shorter than that of hot-rolled seamless steel pipe. The wall thickness of cold-rolled seamless steel pipe is generally smaller than that of hot-rolled seamless steel pipe, but the surface looks brighter than thick-walled seamless steel pipe, and the surface is not too It's rough and there aren't too many burrs in the caliber. Buyers often choose the right one according to their specific needs.
The seamless steel tubes, the different fields used, the different types of seamless steel tubes required also have certain differences in terms of types and materials. In general, such pipeline materials are more advantageous in terms of cost performance.

The delivery status of the seamless steel pipe is generally delivered after the heat treatment in the hot rolled state. Because the hot-rolled seamless steel pipe has undergone strict manual selection by the staff after the quality inspection, each step is perfect and perfect. After the quality inspection, the surface is oiled, and then the cold drawing test is repeated several times. After the hot rolling treatment, the experiment of perforation is carried out. If the diameter of the perforation is too large, the straightening correction is performed. After the straightening, the conveyor is sent to the flaw detector for the flaw detection experiment. This step is also essential. Finally, the label is placed, the specifications are arranged, and then placed in the warehouse. Through this series of steps, it is to better ensure the quality of the seamless steel pipe before leaving the factory.

Therefore, the choice to purchase this type of pipe material is completely reassuring, because seamless steel pipe needs to be professionally tested before it goes out, which not only guarantees the quality, but also makes the customer buy more confidence, do not have to worry about buying shoddy pipe materials.

Difference Between Spiral Welded Pipe and Straight Welded Pipe

The main difference between the two welded pipes of spiral welded pipe and straight welded pipe is the difference in welding form. Spiral welded pipe is a low carbon carbon structural steel or a low alloy structural steel strip rolled into a tube blank with a certain helix angle (also called formin ...

Comparison of Welding Technology Between Straight Seam Welded Pipe and Spiral Welded Pipe

The material produced by the spiral welded pipe( SSAW steel pipe ) is a hot rolled coil, and the straight welded pipe is made of steel plate. The amount of alloy contained in the coil is less than that of the steel sheet. For this reason, the spiral welded pipe has higher weldability than the stee ...
