Length of Seamless Steel Pipe

Length of seamless steel pipe

Seamless steel pipe is a long steel pipe with a hollow cross-section and no seams around it. Its length standards usually have specifications such as 6 meters, 9 meters, and 12 meters, of which 6 meters is the common standard length. The length of seamless steel pipes from different manufacturers and specifications may vary. Some customized needs may also require the production of seamless steel pipes of other length specifications. However, the specifications of 6 meters, 9 meters, and 12 meters are the most common and the most used. We can confirm the required length before purchasing.

Usual length of seamless steel pipe (also known as non-fixed length): Any length within the length range specified in the standard and without a fixed length requirement is called the usual length. For example, the standard for structural pipes stipulates: hot-rolled (extruded, expanded) steel pipes 3000mm~12000mm; cold-drawn (rolled) steel pipes 2000mmm~10500mm.

Common length of seamless steel pipes

1. 6-meter seamless steel pipes can be cut directly on site, which is convenient and flexible.

2. 9-meter and 12-meter seamless steel pipes are often used for long-distance transportation, especially when they need to pass through multiple provinces or even national borders. These lengths can reduce transportation costs and time and improve efficiency.

Length ranges commonly selected in practical applications

Seamless steel pipes are often used in petroleum, chemical, natural gas, water conservancy, construction and other fields. In these fields, the length of steel pipes selected in practical applications usually ranges from 6 meters to 12 meters.

For occasions where shorter lengths are required, the steel pipes can be cut into appropriate lengths during the production process. However, some special needs, such as in some marine exploration fields, require the length of the steel pipe to be extended to more than 12 meters. At this time, special attention should be paid during the design and production process.

Length reference for common specifications and models

The following are some common specifications and models of seamless steel pipe length references:
1. Seamless steel pipes with an outer diameter of less than 57mm are generally 4-8 meters in length.
2. Seamless steel pipes with an outer diameter of 57mm-159mm are generally 6-12 meters in length.
3. Seamless steel pipes with an outer diameter greater than 159mm are generally 6-18 meters long.

It should be noted that when choosing seamless steel pipes, in addition to considering the length, different materials and specifications need to be selected according to the specific use conditions to ensure the use effect and safety.

Precautions for purchasing seamless steel pipes

1. Determine the actual required length of the steel pipe. Generally, the length specification of 6 meters to 12 meters can meet most application requirements.
2. Pay attention to the quality of the steel pipe, especially for steel pipes that need to be used in harsh environments, the quality issue is more important.

3. Select materials according to actual use conditions and choose suitable steel pipe materials and specifications.

Conclusion

Seamless steel pipe is a pipe material commonly used for conveying fluids and gases. Its length standard and common length have an important impact on engineering construction, transportation and use. Choosing the right length and specification can provide strong support for the smooth progress and long-term operation of the project.

The length specification standards of seamless steel pipes are 6 meters, 9 meters, 12 meters, etc. In actual applications, the length range usually selected is 6 meters to 12 meters. When purchasing, you need to make a choice based on actual needs and usage conditions, and pay attention to the quality and material selection of the steel pipe.
