Difference Between Psl 1 And Psl 2
Preface of API 5L pipe.
The American Petroleum Institute (API) establishes several requirements for the sale of line pipe. PSL-1 and PSL-2 are the API 5L pipe specifications. These specifications apply to seamless and welded steel line pipe in grades X42 through X80. API 5L pipe is often used in the hydrocarbon petroleum and natural gas industries for transferring gas, water, and oil.
API 5L pipes are used to carry gas, water, and oil in the oil and natural gas industries. Line pipe may be used for both on- and off-shore oil and gas transmission and can meet all high-pressure transmission pipeline requirements for natural gas and petroleum.
The American Petroleum Institute created the API 5L standard. API 5L steel line pipe can be either seamless or welded. Tirox Steel India is one of India's leading API 5L pipeManufacturer in India ...

Summary:
PSL stands for product specification levels. Because the product specification level pipeline is separated into PSL1 and PSL2, the quality level may also be classified into PSL1 and PSL2. PSL2 is higher than PSL2, these two specification levels not only have different testing requirements, but also different chemical composition and mechanical properties requirements, so when ordering according to API 5L, terms of the contract must also indicate the product specification level, ex PSL 1 or PSL 2. PSL2 is more strict than PSL 1 in terms of chemical composition, tensile qualities, impact energy, non-destructive testing, and other indications.
Difference between PSL1 and PSL2 pipes are as follows:
Chemical Properties
Mechanical Properties
Manufacturing Methods
Inspection and Defect Repair
Certification & Traceability
PSL-1 is a flexible quality standard for line pipe, but PSL-2 includes more testing requirements, tighter chemical physicals, different mechanical property ceiling constraints, and Charpy impact testing conditions.
The maximum carbon concentration for Seamless PSL1 pipe in grades B and above is 0.28 percent. In all grades, the maximum carbon concentration in PSL2 pipes is 0.24 percent.
The allowable carbon content for welded PSL1 pipe is 0.26 percent for grades B and higher. In all grades, the maximum carbon concentration in PSL2 welded pipes is 0.22 percent.
The second element is phosphorus; the maximum phosphorus content for PSL1 pipe is 0.03 percent for grades A and higher. In all grades, the maximum phosphorus concentration in PSL2 pipes is 0.03 percent.
The only difference is that this time the grade isn't an A.
Sulphur is the third element in the periodic table, with a maximum sulphur level of 0.03 percent in PSL1 pipe. The sulphur level of PSL2 pipes is restricted to 0.02 percent.
Tirox Steel India is one of India's leading API 5L pipeManufacturer in India.
It is one of the best API 5L X42 PSL1 / PSL2 Pipe manufacturers
Tirox Steel India is an Indian manufacturer of API 5l X42 Pipe.
A piping system that meets the latest standards, API 5L X42, is a necessary upgrade for any system that was built before the late 1980s.
