Product details

API 5L GR.B SSAW pipe refers to a type of steel pipe that conforms to the specifications of API 5L Grade B and is manufactured using the Spiral Submerged Arc Welding (SSAW) process.

API 5L Grade B is one of the commonly used grades specified in API 5L. It has a minimum yield strength of 42,000 psi (290 MPa) and a minimum tensile strength of 60,000 psi (415 MPa). Grade B pipes are suitable for applications where the focus is primarily on the mechanical properties of the pipe.

API 5L GR.B SSAW pipes undergo stringent quality control measures during manufacturing to ensure compliance with the specified API 5L requirements. This includes testing for dimensions, mechanical properties, chemical composition, non-destructive testing, and visual inspection.

API 5L GR.B SSAW pipes are commonly used in various pipeline projects for the transportation of oil, gas, and water over long distances. They are designed to meet the specific requirements of the application and ensure reliable and efficient fluid transportation.

The process of Ssaw steel pipe:
Steel coils→Ray material test → Delivery straightening → Plate cutting and welding → circle shear edge milling → Forming → inside auto-welding → Outside auto-welding → Online ultrasonic inspection → Fixed length cutting → Visual inspection for outside seam → Visusl inspection for inside seam → X-ray inspection for welding seam → Even end and end bevel → Hydrostatic test → Ultrasonic inspection → Final product inspection → Marking → Store up
