Q: Can you do polished finish for the tubes/pipes?

A: Yes, for welded tubes/pipes, we can do mirror polishing, 600# polishing, 500# polishing, 320# polishing, 240# polishing and so on, brushed finish is also available. For seamless tubes/pipes, normally the surface is pickled finish, while brushed finish is also doable.


Q: What’s your standard package?

A: Our standard package is waterproof plastic bags with wraps. For advanced packing, we can provide round paper tube for each tube, and wooden/metal case for exterior packing.


Q: Where’s your main market?

A: South America, Mid-east, South-east Asia, Europe and so on.


Q: Do you also have the accessories for the tubes?

A: Yes we can provide the accessories too.


Q: What length is your standard length? Can I have the tubes/pipes cut into the length I want?

A: Our standard length is 3meter, 4meter, 5meter, 6meter. If you length is less than 3meter, we will have to run an additional processing for cutting which will bring some more costs. The minimum length is 500mm. For seamless tubes, we can make maximum to 12, 13meters.

Stainless steel capillary tubes come in various specifications, such as different grades, sizes, and thicknesses. These specifications can affect the performance and suitability of the tubes for different applications.


Firstly, the grade of stainless steel used in the capillary tubes can affect its properties. For example, 316 stainless steel capillary tubes offer higher corrosion resistance and high-temperature resistance than 304 stainless steel capillary tubes, making them suitable for certain industrial and chemical applications. On the other hand, 304 stainless steel capillary tubes are often preferred for medical and laboratory applications due to their excellent biocompatibility and low cost.


Secondly, the size of the capillary tube can vary widely, with the internal diameter ranging from a few micrometers to a few millimeters. The size of the tube can affect its flow rate, pressure drop, and other performance characteristics. For example, smaller diameter tubes may have higher resistance to flow and require higher pressure to achieve a certain flow rate. Therefore, the choice of tube size should consider the specific application and requirements.


Lastly, the thickness of the capillary tube can also vary, affecting its durability and stiffness. Thicker-walled tubes may be more robust and resistant to external stresses, while thinner-walled tubes may be more flexible and have lower resistance to pressure. Again, the choice of tube thickness should consider the specific application and requirements.
