Vigor API 5L line pipes are carbon steel pipes used for oil and gas transmissions. They include pipes manufactured in seamless and welded. Depending on the strength, schedule, and service requirements, API 5L pipes are manufactured in various grades and are suitable for both different applications.

API 5L Line pipe is the most important transportation equipment of crude oil and petroleum products. Compared with railway and road, which are both land transportation modes, line pipe oil transportation has the characteristics of large volume, good tightness, low cost and high safety factor.

The pipe used in the oil line pipe is mainly carbon steel pipe, which can be divided into seamless steel pipe and welded steel pipe according to its manufacturing process. Seamless steel pipe has the characteristics of high strength and many specifications, so it is suitable for the transportation of highly corrosive oil or high temperature conditions. Seamless steel pipes are divided into hot rolled and cold drawn two kinds. Because the cold drawing process will cause the material to harden, it is also necessary to do the corresponding heat treatment according to the specific use of the pipe. Welded steel pipes can be divided into two kinds: seam steel pipes and spiral welded steel pipes. Due to the process characteristics of carbon steel pipe, this kind of steel pipe is easy to become brittle at low temperatures, so it is mainly suitable for normal temperature pipelines, and the use temperature of the pipe should not exceed 300 degrees Celsius, in general, the use temperature of ordinary carbon steel pipe is between 0 and 300 degrees Celsius. If high-quality carbon steel pipes are used, the temperature application range and relaxation can reach -40 to 450 degrees Celsius. The experimental pressure of the steel pipe is generally 1.5 times the nominal pressure. When the temperature of the conveying material does not exceed 200 degrees Celsius, the working pressure is the nominal pressure. When the temperature exceeds 200 degrees, the working pressure should be correspondingly lower than the nominal pressure.

API 5L line pipes must use certain links to form a complete system. There are three types of pipe connection: wire, welding and flange connection. The pressure is not high and the pipe diameter is not large. The wire connection method can be used to connect the pipe. This connection method is more convenient, but because most of the main oil pipeline diameter is generally large, the other two connection methods are used. The pipes with DN Greater than or equal to 50 are basically connected by welding, which has the advantages of convenient construction, firm, tight and steel saving. Generally, the parts that do not need to be disassembled on straight pipes or bends can be used. The connection of pipe and valve or other equipment (such as: pump) and the place where the pipe needs to be disassembled are connected by flanges.

API 5L line pipe mainly has the transportation technology of isothermal transportation, heating transportation and sequential transportation. Line pipe corrosion and how to prevent corrosion is one of the important links of pipeline maintenance. Line pipe has become one of the main transportation tools of oil, and still has considerable potential for development in the future.
