The pipe industry has become so big to have various pipes for use in many applications in several sectors. Hence it makes it challenging for buyers and users to choose the right pipe for their specific use safely and cost-effectively

You have come to the right place to know which is better between API 5L Grade B Seamless Pipe and welded pipe. I have enough experience in the pipe field to answer it and more about the API 5L pipes to choose the best pipes suitable for your applications.

The two important forms of pipes are seamless and welded pipes, with different properties. While the seamless pipes get extracted and drawn from the billets, the welded pipes get produced from strips in roll forms and welded.

As the name suggests, the seamless pipes are seamless as no welding is available in long lengths. But because of many welding processes, the welded pipes are not as seamless as the pipes. However, welded pipes are cheaper than seamless pipes, which are useful in many applications like oil & gas.

The difference between API 5L Grade B Welded Pipe and seamless pipes include:

Though API 5L Grade B and X52 both follow the specifications of the American Petroleum Institute’s specifications, there are a few differences between them, including:

Knowing the tensile strength of pipes is important before buying them to be suitable for specific applications. Failing to do so will break the pipes due to excess tension to cause damage.

API 5L Grade B Pipe has a minimum tensile strength of 415 MPa to is the most common pipe for use in carrying oil, gas and water in many industries, also because of its yield strength of a minimum of 240 MPa.

Like other API 5L grades with two product specifications, grade B pipes also have PSL 1 and 2. Though there are a few common similarities, there are also differences between the API 5L Gr B PSL2 Pipe and PSL 1 pipe that include:

High or low temperatures for pipes could make them burst to cause damage. Hence it is essential to know the temperature of API 5L Grade B Carbon Steel Pipe to use it safely.

There are many specifications for temperature by premier institutions like the ASME B 31.3 to have the minimum temperature for API 5L pipes at -20F. Though there are chances for pipes to freeze below 20 degrees Fahrenheit, a temperature between 50 to 80 F is ideal for pipes.
