What is the api 5l x70 pipe specifications elongation

Standard:API 5L PSL1|PSL2.
Scope:API 5L is generally refers to the standards of pipeline steel, include pipeline pipe and pipeline steel plate.
API 5L line pipe steel grade levels:GR. B, X42, X46 and X52, X56, X60, X70 and X80.
Details

API 5L steel is pipeline steel mainly for use in oil and gas industry. API 5L steel has PSL1 and PSL2 levels. For same API 5L steel grade, the carbon content for PSL1 is higher than PSL2. Meanwhile, the API 5L PSL2 steel has more strict requirement for P, S content than API 5L PSL1 steel, api 5l X70 pipe specifications. Therefore, API 5L PSL2 steel strength is higher than API 5L PSL1 steel strength. For example, API 5L X42 PSL2 yield strength is 317-524 MPa, tensile strength is 434-758 MPa. While API 5L X42 PSL1 yield strength is 290 MPa min. , tensile strength is 414 MPa min.

Key points of welding joint design: under the condition of satisfying the requirement of welding penetration depth and weld density, small welding groove Angle and gap should be adopted.In the api 5l X70 pipe specifications Angle joint, a symmetrical groove or a groove inclined to the side plate is used.Double - sided groove symmetric welding is used instead of single groove asymmetric welding.In a T-shaped or Angle joint, the end of the plate subjected to welding tensile stress in the thickness direction extends out of the joint weld zone.

Phosphorus is a very harmful element in api 5l X70 pipe specifications steel. With the increase of phosphorus content, the strength, flexion ratio and hardness of api 5l X70 pipe specifications steel increased, but the plasticity and toughness decreased significantly. In particular, the lower the temperature, the greater the impact on plasticity and toughness, increase the cold brittleness of steel.

The company will regularly hold the award ceremony for excellent employees. he award-winners prove their excellence and the team’s excellence with api 5l X70 pipe specifications great achievements.On Oct., 2018 the Management star is Ms. Sherry from International Trade Department. The sales star is Ms. Katrina from International Trade Department. Under the guidance of Ms. Sherry, the old customer maintenance team of api 5l X70 pipe specifications BBN steel completed 309% sales task in Oct., 2018. Ms. Katrina has been using her own actions to interpret the "pursuit of excellence, continuous innovation" spirit of BBN enterprise.
