What is API 5L Gr B pipe?
API 5L Grade B pipe is a common grade pipe for oil and gas pipeline transmissions. It also called L245 Pipe refer ISO 3183, named by minimum yield strength 245 Mpa (355,000 Psi). Equivalent material ASTM A106 B or ASTM A53 B, which have similar value on chemical composition, mechanical properties, and applications.
What is API 5L specification?
API Spec 5L is an International Standard that specifies requirements for the manufacture of two product specification levels (PSL 1 and PSL 2) of seamless and welded steel pipes for use in pipeline transportation systems in the petroleum and natural gas industries.
What is a Grade B pipe?
ASTM A106 grade B Seamless Pressure Pipe (ASME SA106) is used in power plants, boilers, petrochemical plants, oil and gas refineries, and ships where the piping must transport fluids and gases that exhibit high pressures and temperatures.
What is API 5L PSL2?
API 5L seamless & welded pipe ANSI / API 5L specifies the manufacture of two product levels (PSL1 and PSL2) of seamless and welded steel pipe for the use of a pipeline in the transportation of petroleum and natural gas.
What is the difference between a grade and B grade steel?
Grade B has a carbon percentage that usually ranges around 0.30% which is higher than grade A but not as strong as grade C. The maximum carbon content that is allowed is highest in grade C which will end up resulting in higher mechanical properties due to that increased carbon content.
What is ASTM A53 Grade B?
Covers black and hot-dipped galvanized electric-resistance welded Grade B pipe. Pipe is intended for mechanical and pressure applications and is acceptable for ordinary uses in steam, water, gas and air lines.
What is the difference between API 5L PSL1 and PSL2?
Line pipes in API 5L PSL2 is higher than PSL1 The product standard level of line pipe have PSL1 and PSL2, also we could say the quality standard divided in PSL1 and PSL2. PSL2 is higher than PSL1, not only the inspection standard is different, also the chemical property, mechanical strength standards are different.
What’s the difference between PSL1 and PSL2?
PSL-1 is a loose standard quality for line pipe, whereas PSL-2 contains additional testing requirement, stricter chemical physicals, along with different ceiling limits of mechanical properties, and require Charpy impact testing conditions.
