Standard length range of seamless pipes

Standard length range of seamless pipes (SMLS):

1. International standards
According to international standards, the fixed length of seamless pipes should be between 3 and 12m. Among them, 3~5.8m is the normal length, and 6~12m is the double length. These standards are mainly applicable to seamless pipes in petroleum, chemical industry, natural gas, shipbuilding and other fields. Different industries use different pipes, and some industries may require different pipe lengths.

2. Chinese standards

Domestic standards also have clear regulations on the fixed length of seamless pipes. The GB/T 8163-2008 standard stipulates that the fixed lengths of seamless steel pipes are 6m, 9m, and 12m. The GB/T 3087-2008 standard stipulates that the length of boiler seamless steel pipes is 4~12m. It is worth noting that some domestic manufacturers have their own special length specifications, and users should choose the manufacturer that meets their needs.

3. Common length ranges
The fixed length range of seamless pipes is generally between 3 and 12m, but different industries have different requirements for pipe lengths. For example, some pipes for short-distance transportation often require a length between 1 and 3m. Some pipes that require a lot of bending need to be shorter in length to facilitate processing. For some large-scale buildings or equipment pipes, longer lengths are required, which can reach more than 18m.

4. How to choose the appropriate seamless pipe length?

Several factors need to be considered when selecting the appropriate seamless pipe length. The first is the purpose of the pipe and the required length range. Different application scenarios have different pipe length requirements and need to be selected according to specific circumstances. The second is the requirements for manufacturers. Some manufacturers have special specifications for fixed lengths or provide higher quality pipes, and you need to make a choice based on your own needs. Finally, there is the consideration of price. The prices of pipes of different lengths are also different, so you need to choose according to the actual situation.

In short, the standards for the fixed length range of seamless pipes are divided into international standards and domestic standards. The length range is generally between 3 and 12m, but different industries have different requirements for pipe length. Selecting the appropriate seamless pipe length requires consideration of many factors, including the pipe's purpose and required length range, manufacturer's specifications, price, etc.

Tips: ASTM A106 (ASME SA106) seamless pipes can transport fluids or gases under high temperature and pressure. There are three grades: A, B, and C. The most commonly used ASTM A106 grade B is widely used in oil and natural gas refineries, power plants, petrochemical project factories, and boilers. and ship construction. These pipelines must carry fluids and gases that exhibit higher temperature and pressure levels.
