What Are The Classifications of Stainless Steel Precision Tubes?

Stainless steel precision tube, as a stainless steel tube with quality standards beyond the ordinary, are unique in the field of tubes with their extraordinary quality standards. Its high quality requirements cover the accuracy of size, the roundness of the tube mouth and excellent pressure resistance. Further, we can classify and understand stainless steel precision tubes in more detail from multiple aspects such as tube wall thickness, tube mouth size, tube cross-section shape, and material.

Wall thickness

Stainless steel precision tubes can be divided into thin-walled tubes and thick-walled tubes according to tube wall thickness.

1. Thin-walled stainless steel precision tubes

The ratio of wall thickness to outer diameter of thin-walled tubes is less than 6%. It has excellent heat dissipation performance and is often used as the heat exchanger tube. The inner tube wall needs to be kept smooth to reduce scaling. It is suitable for central air conditioners, boilers, refrigerators and other equipment.

2. Thick-walled stainless steel precision tube

The ratio of wall thickness to outer diameter of thick-walled stainless steel tube is greater than or equal to 6%. Its weld must be fully penetrated, showing excellent pressure resistance, mechanical properties and abrasion resistance. It is often used in the manufacture of parts for textile equipment, electroplating equipment, and dyeing equipment.

Tube size

Precision tubes can also be further classified according to the size of the tube, including small-diameter and large-diameter precision tubes.

1. Small-diameter stainless steel precision tube

The diameter range of small-diameter stainless steel precision tubes is usually between 0.7 and 8 mm. This type of tube not only has good corrosion resistance and tensile resistance, but also meets stringent standards in the control of tube error. For this reason, it is widely used in the manufacture of optical circuits, thermal instruments and automation instruments.

2. Large-diameter stainless steel precision tube

Large-diameter tubes play a key role in the manufacture of industrial pipelines, nuclear energy, electricity and sewage treatment equipment due to their excellent fluid transportation capabilities. In addition, large-diameter pipes need to undergo bright solution treatment and pickling passivation processes to further improve their corrosion resistance.

Cross-sectional shape of pipes

The cross-sectional shapes of pipes vary, and the most common ones are round pipes, square pipes and special-shaped pipes.

1. Round and square tubes

Due to their unique characteristics, round and square tubes are widely used in many fields, such as water outlet pipes of drinking fountains, filter cartridges of water purification equipment, and parts of lighting.

2. Special-shaped tubes

Special-shaped stainless steel precision tubes, such as fan-shaped tubes, triangular tubes, elliptical tubes and grooved tubes, may not be familiar to many people. Nevertheless, they play an indispensable role in the fields of bathrooms, machinery, etc., such as pipe fittings for bathroom shower racks, pipes for faucets, heat exchange pipes for gas water heaters, and structural tubes for mechanical equipment. It is worth noting that special-shaped tubes have extremely high requirements for the precision of the tube mouths, and any deviation may affect their later processing and installation.

Material

The material of the pipe also affects its application range. The more common ones are 304 and 316 stainless steel.

1. 304 stainless steel

304 stainless steel precision tube has good corrosion resistance and plasticity, and is suitable for a variety of conventional applications, such as food processing, indoor equipment, etc.

2. 316 stainless steel

316 stainless steel precision tube has better corrosion resistance and chloride erosion resistance, and is usually used in chemical, marine equipment and medical equipment and other fields with high material requirements.

Summary

Stainless steel precision tube has become an important material in modern industrial and civil equipment manufacturing with precise size control, excellent pressure resistance and a variety of material choices. Whether in air conditioning heat exchange, industrial transportation or precision instruments, the reasonable selection and application of stainless steel precision tube can significantly improve the performance and service life of the equipment.
