L245 is a low-carbon pipeline steel grade with a specified minimum yield strength of 245 MPa. It is widely used in spiral submerged arc welded (SSAW) steel pipe production because its chemical composition and mechanical properties support stable forming and welding. The grade offers a practical balance of strength, plasticity and toughness for low and medium pressure pipeline systems.
For pipeline projects, L245 spiral steel pipes provide good weldability and adequate toughness for handling, installation and normal service conditions. The spiral forming process allows a range of large diameters and wall thicknesses, which helps meet different design requirements. As a common pipeline grade, L245 also supports reasonable material and construction costs. When combined with external coatings such as 3PE, TPEP or IPN8710, and with thermal insulation systems, the pipe can be adapted to different soil, climate and operating conditions.
Typical application fields include water supply and drainage, gas transmission, heating networks, agricultural irrigation, piling and structural support. Cangzhou Youcheng Pipeline Technology Co., Ltd. produces SSAW L245 spiral steel pipes and related anti-corrosion and insulation products. Project teams are advised to confirm steel grade, dimensions, coating type and applicable standard before ordering.
