Applications of Seamless Square Tube

 

 

Structural seamless steel pipe is a seamless steel pipe which used for general structures and mechanical structures.


Seamless steel pipes for fluid transportation are general seamless steel pipes which used to transport fluids such as water, oil, and gas.


Seamless steel pipe for petroleum cracking is a seamless steel pipe suitable for furnace tubes, heat exchangers and pipelines in petroleum refineries.


Steel pipes for geological drilling are steel pipes used by geological departments for core drilling. According to their uses, they can be divided into drill pipes, drill collars, core pipes, casings and sedimentation pipes, etc.


Seamless steel pipe for diamond core drilling is a seamless steel pipe used for drill pipe, core rod and casing for diamond core drilling.


High-pressure oil pipe for diesel engines is a cold-drawn seamless steel pipe used to manufacture high-pressure pipes for diesel engine injection systems.


Special-shaped seamless steel pipe is a general term for seamless steel pipes with other cross-sectional shapes other than round pipes.

 

Cutting Method of Seamless Square Tube
 

Mechanical cutting.
Mechanical cutting adopts both external installation and internal installation. It uses the turning tool processing principle to cut off and bevel the nozzle. The single machine has a large span, can be processed with a large thickness, less waste, and has no pollution. The processing process does not generate high temperature. Does not affect the pipe material, which is conducive to welding. Water cutting uses high pressure pumps and corundum to process pipelines. The cuts are clean and the processing span is large, but its efficiency is low and the processing thickness is severely restricted.

 

Oxygen acetylene flame cutting.
By adjusting the oxygen valve and acetylene valve, the mixing ratio of oxygen and acetylene can be changed to obtain three different flames: neutral flame, oxidized flame and carbonized flame.

 

Ion cutting.
Plasma cutting with different working gases can cut a variety of oxygen cutting difficult-to-cut metals, especially for non-ferrous metals (stainless steel, aluminum, copper, titanium, nickel); its main advantage is that it cuts metal with small thickness At the time, plasma cutting speed is fast, especially when cutting ordinary carbon steel sheet, the speed can reach 5 ~ 6 times of the oxygen cutting method, the cutting surface is smooth, the thermal deformation is small, and there is less heat affected zone.

 

Precautions for Storage of Seamless Square Tubes

 
Choose a storage location

Seamless square tubes should be stored in a dry, ventilated, and clean place, away from acid and alkali substances and corrosive gases. The place should be equipped with moisture-proof, dust-proof, and anti-vibration measures to ensure that the goods are not damaged during long-term storage.

Stacking method

Pay attention to stability and balance when stacking seamless square tubes. Appropriate support measures should be used to evenly distribute gravity and avoid bending or deformation. seamless square tubes cannot be stacked directly on the ground. Wooden boards or steel plates should be used for separation.

Protective measures

When storing seamless square tubes, they need to be covered with covers or plastic films to avoid erosion of the goods by dust, rain, etc. In addition, regular inspections should be carried out to remove blockages or dirt in a timely manner.

Regular flipping

In order to avoid deformation and corrosion of seamless square tubes caused by long-term storage, it is recommended to turn over regularly during storage. This helps balance gravity and maintain the shape and quality of seamless square tubes.

Reasonable labeling

Seamless square tubes should be well labeled when stored, including product specifications, batches, production dates and other important information to facilitate management and identification during use. At the same time, it is also convenient to understand the storage status and usage of the goods.
