Api 5l Gr B Pipe

API 5L Grade B (API 5L Gr B) is a pipeline steel grade that complies with American Petroleum Institute (API) standards and is suitable for pipelines transporting liquids and gases such as oil and natural gas.

 

API 5L Gr B pipe is manufactured using a seamless method, providing a continuous pipe body with no welded or joined sections. This manufacturing method gives the pipe greater strength and durability.

 

API 5L Gr B Carbon Tubing is available in diameters ranging from 1/2" to 60", providing a variety of size options for a variety of different applications and projects. Pipes range from Sch20 to Sch160, representing the range of pipe wall thickness. Sch20 represents the thinnest wall thickness, while Sch160 represents the thickest wall thickness.

 

API 5L Gr B steel pipes are available in different product specification levels, such as PSL1 and PSL2, which may refer to different pipe quality and performance standards. Different grades of pipes have different characteristics and scope of application. gnee can provide different pipe coatings, such as black paint, varnish and 3LPE coating. These coatings can increase the corrosion resistance and aesthetics of pipes, providing users with more choices.

 

The content of API 5L Grade B Psl2 steel pipe includes carbon, manganese, phosphorus, sulfur, silicon, copper, nickel, chromium, molybdenum, vanadium and other elements. The high manganese content in API 5L Gr B gives it a minimum yield strength of 245MPa, indicating that it can be used in both offshore and onshore pipeline applications. This high strength enables it to withstand a wide range of pressures and environmental conditions.

The transportation and packaging process of API 5L Gr B pipeline, the specific steps are as follows:

End processing of API 5L pipe, including plain end, threaded end and socket end. Surface treatment of API 5L Gr B steel pipe, including rust removal, anti-rust paint application, etc. Packing of steel pipes: Pack steel pipes into packaging bags according to specifications and quantity. The packaging bag is sealed by heat sealing or gluing. For the fixation of steel pipes, wooden frames, cartons and other materials are used to fix the steel pipes in packaging bags. Label affixing: affix a label on the packaging bag to indicate the specifications, quantity, production date and other information of the steel pipe. Inspection before shipment, check whether the packaging is intact, whether the label is clear, etc.
