Standard length range of seamless pipes

Standard length range of seamless pipes (SMLS):

1. International standards

Seamless pipes must adhere to international standards, with a fixed length ranging from 3 to 12m. The normal length is between 3~5.8m, while the double length is between 6~12m. These standards apply primarily to seamless pipes used in the petroleum, chemical, natural gas, shipbuilding, and related industries. Different industries require different types of pipes, and some may necessitate varying pipe lengths.

2. Chinese standards

Domestic standards have clear regulations on the fixed length of seamless pipes. According to the GB/T 8163-2008 standard, seamless steel pipes come in fixed lengths of 6m, 9m, and 12m. The GB/T 3087-2008 standard specifies that the length of boiler seamless steel pipes should be between 4m and 12m. It is important to note that some domestic manufacturers have their own special length specifications, so users should choose a manufacturer that meets their specific needs.

3. Common length ranges

Seamless pipes typically have a fixed length range of 3 to 12m. However, pipe length requirements vary across industries. Pipes used for short-distance transportation often require a length between 1 and 3m. Pipes that require a lot of bending need to be shorter to facilitate processing. Large-scale buildings or equipment pipes require longer lengths, which can exceed 18m.

4. How to choose the appropriate seamless pipe length?

When selecting the appropriate seamless pipe length, several factors must be considered. Firstly, the purpose of the pipe and the required length range should be taken into account. Different application scenarios have varying pipe length requirements, which should be selected based on specific circumstances. Secondly, the manufacturer's requirements should be considered. Some manufacturers have special specifications for fixed lengths or provide higher quality pipes, and a choice should be made based on individual needs. Finally, when considering purchasing pipes, it is important to take price into account. Pipes of varying lengths will have different prices, so it is important to choose based on your specific needs.
