What is API 5L X52 Steel Pipe ?
API 5L X52 steel pipe has an extraordinary minimum tensile strength of 360 MPA. These pipes are extremely durable, providing long-term functionality and cost effectiveness by reducing the need for frequent replacement. In addition, they are heat treated to increase mechanical strength and reduce hardness. These pipelines have excellent tensile strength and are ideal for drilling operations. They have excellent corrosion resistance and can withstand high pressure environments, making them ideal for the oil, petrochemical, oil and gas industries.
what is API 5L Standard
This specification covers seamless and welded steel line pipe. It includes plain-end, threaded-end, and belled-end pipe,as well as through-the-flow line (TFL) pipe and pipe with ends prepared for use with special couplings.
The purpose of this specification is to provide standards for pipe suitable for use in conveying gas, water, and oil in both the oil and natural gas industries.

Application
The non-flammability of this grade makes it suitable for sensitive projects, such as electricity generation by nuclear, thermal, geothermal and hydraulic methods. In addition, these pipelines are used in flood control, textile industry, sugar industry and building construction. They are used to transport gases, vapors and various liquids.
It is worth noting that the API 5L class X52 pipeline is divided into two different levels: PSL-1 and PSL-2. PSL-1 pipes do not require impact and non-destructive testing, unlike PSL-2 pipes.
