What is a structural pipe?

For structural pipes, this standard applies to seamless steel pipes for general structures and mechanical structures. The fluid seamless steel pipe standard applies to general seamless steel pipes for transporting fluids.

The main difference between it and structural seamless steel pipes is that fluid seamless steel pipes undergo hydraulic testing or ultrasonic, eddy current, and magnetic flux leakage testing one by one. Therefore, in the standard selection of pressure pipeline steel pipes, it is not suitable to use fluid seamless steel pipes. Seamless steel pipes are represented by outer diameter and wall thickness.

Thick-walled seamless steel pipes are mainly used in mechanical processing, coal mines, hydraulic steel, and other purposes. The materials of thick-walled seamless steel pipes are divided into 10#, 20#, 35#, 45# 16Mn, 27SiMn, 12Cr1MoV, 10CrMo910, 15CrMo, 35CrMo, etc.

Classification of thick-walled seamless steel pipes - hot-rolled thick-walled seamless steel pipes, cold-rolled thick-walled seamless steel pipes, cold-drawn thick-walled seamless steel pipes, extruded thick-walled seamless steel pipes, and jacking pipes. Stainless steel seamless steel pipe for structural use (GB/T14975-1994) is a hot-rolled (extruded, extruded, Expanded) and cold drawn (rolled) seamless steel pipes.

How is structural pipe measured?

Weight calculation formula:（OD-Thickness）*Thickness*0.02466=kg/m

What is structural pipe used for?

Steel structure steel pipe is a kind of steel structure supply. This kind of steel is generally connected using welds, rivets and bolts. They are relatively light in weight and easy to construct, and are widely used in construction.

Structural pipes are widely used in various fields and have many uses:

1. Construction field: Structural pipes are often used in water pipes, heating pipes, ventilation pipes, etc. outside buildings. They can transport water, gas, steam and other media to meet the normal use needs of buildings.

2. Engineering: During the process of machinery manufacturing and equipment installation, the main guide tubes and mechanical pipe connectors of the structural pipes play the role of support, fixation and diversion.

3. Petrochemical industry: In the transportation process of chemical products such as petroleum and natural gas, structural pipes are indispensable pipeline equipment. They can withstand high temperature and high pressure environments and ensure the safe transportation of media.

4. Food processing: In food processing, structural pipes can be used to transport and store various liquids and powders, such as milk, juice, alcohol, etc., and are required to have hygienic and safe characteristics.

5. Pharmaceutical industry: Structural tubes are widely used in drug transportation, raw material storage and other tasks. They can keep the medium pollution-free, tasteless and odorless, ensuring the quality and safety of drugs.

6. Other industries: Structural pipes can also be used in automatic fire sprinkler systems, air conditioning systems, exhaust gas treatment systems, etc., to provide stable and reliable operation for these systems.

To sum up, as a standard pipe part, structural pipe has high strength, corrosion resistance and good sealing performance. It is easy to install and is widely used in construction, machinery, petrochemical, food processing, pharmaceutical and other industries. It can withstand pressure, guide media in various working environments, and ensure stable operation of the system. The characteristics and uses of structural pipes make it one of the important piping equipment in various industries.
