Maintenance method of seamless steel pipe

Maintenance method of seamless steel pipe

Seamless pipe is a seamless hollow long steel pipe. The steel pipe has a hollow cross-section and is widely used as a pipeline for conveying fluids. Seamless pipe standards such as oil, natural gas, natural gas, natural gas, water and some solid material pipelines. In fact, this product is mainly compared with solid steel such as round steel. When its bending and torsional strength is the same, the weight of the steel pipe is lighter and it is an economical steel. 

Seamless pipes are widely used in the manufacture of structural mechanical parts such as oil drill pipes, automobile transmission shafts, bicycle frames, and steel scaffolding for construction. In addition, the product uses steel pipes as rings, which can improve material utilization, simplify manufacturing processes, and save materials and processing time, such as rolling bearing rings, jack sleeves, etc. At present, this product is actually being manufactured and has been widely used. Therefore, more fluids can be conveyed. In addition, when the ring section is subjected to internal and external radial pressure, the force is relatively uniform, so most steel pipes are round pipes.

Seamless pipes also need to be cleaned during use and maintenance. Cleaning seamless pipes can make seamless steel pipes more neat and sanitary, and give full play to their key main uses in application methods. Now the product is also manufactured in a relatively low temperature environment, with key features and advantages, so now its cleaning requires technical expertise and lubricating fluid to clean.

What are the actual methods and types of lubricants?

Commonly used cleaning lubricants are soap or cooking oil. In fact, it is necessary to remove the burrs on the pipe end before cleaning, and then use the hard pipe nozzle to send out two clean projectiles for cleaning. If there is hydraulic oil or vegetable oil contamination in this seamless pipe, it should be broken up with a hard pipe elastic wheel to remove such contamination more reasonably. If there are rust, weld marks, etc., they should be broken up with a friction spring wheel first, and this contamination should be removed first. The grinder can be used many times until it is determined that the contaminants have been removed. 

Whether using a tube bullet to remove crude oil contamination or a friction bullet to remove rust or weld marks, cleaning with a clean wheel is essential to ensure ideal seamless pipe cleanliness. If the seamless steel pipe is to be cleaned throughout the process, it is recommended to clean the seamless steel pipe before the assembly process. After assembling into the full process, it can only be interrupted and cleaned with a clean projectile wheel. Be sure to pay attention to the joints between the seamless steel pipe and the joint, and there should be no steps. Plastic hose nozzles can also be used to clean seamless steel pipes, but when firing projectiles, they must be done from both ends to ensure that part of the nozzle is blocked for cleaning, which can greatly improve the service life of the plastic hose nozzle.

Maintenance method of seamless steel pipe

1. Anti-rust treatment 

Seamless steel pipes are susceptible to oxidation, corrosion and other factors during production, transportation and storage, so they must be treated with anti-rust. Common anti-rust methods include spraying anti-rust paint, coating anti-rust oil, surface galvanizing, etc. When choosing an anti-rust method, it should be selected according to the application environment and service life of the seamless steel pipe.

2. Regular inspection

In order to ensure the quality and service life of seamless steel pipes, they need to be inspected regularly. The inspection content includes appearance, size, physical properties, etc. If deformation, cracking, corrosion, cracks, etc. are found in seamless steel pipes, they should be repaired or replaced in time.

3. Storage environment 

During the storage of seamless steel pipes, attention should be paid to environmental hygiene, ventilation, dryness and other factors. First, the storage environment should be kept dry to avoid long-term exposure of seamless steel pipes to humid environments; Second, pay attention to ventilation to avoid seamless steel pipes being piled together and unable to ventilate; Finally, the storage area should be kept hygienic to avoid contamination of seamless steel pipes by debris, dust, etc.

4. Avoid collision and friction

Seamless steel pipes are easily affected by collision and friction during transportation and loading and unloading, so collision and friction need to be avoided. During transportation and loading and unloading, pay attention to the use of appropriate equipment and tools to prevent friction and collision between seamless steel pipes and other items.

5. Regular cleaning and lubrication 

Seamless steel pipes are easily affected by dirt during use, so they need to be cleaned regularly. At the same time, pay attention to lubricating seamless steel pipes to avoid affecting their service life due to friction.

6. Storage and use precautions 

During the storage and use of seamless steel pipes, the following matters need to be noted: First, do not expose seamless steel pipes to the sun for a long time; Second, do not let seamless steel pipes be affected by deformation forces such as extrusion and bending; Finally, do not expose seamless steel pipes to corrosive substances such as oil, acid, and alkali to avoid affecting the performance and life of seamless steel pipes.

Conclusion
The above are the maintenance and storage methods of seamless steel pipes. If you want to ensure the quality and service life of seamless steel pipes, you are expected to implement these methods carefully and do a good job of maintaining seamless steel pipes.
