API5L Grade B (L245) steel plate executive standard: API SPEC 5L
API5L Grade B (L245) steel plate delivery status: It can be delivered in hot rolling, controlled rolling, heat treatment (normalizing, tempering, quenching + tempering, etc.).
Steel plates for oil and gas pipelines: X42 (L290), X46 (L320), X52 (L360), X56 (L390), X60 (L415), X65 (L450), X70 (L485), X80. Executive standard: API -5LB (L245). Main purpose: used to make oil and natural gas pipelines. API 5L generally refers to pipeline steel plate-API 5L pipeline steel plate. The pipeline steel plate is processed into large-diameter pipeline
Steel pipe to transport the oil, gas, and water from the ground through the pipeline to the petroleum and natural gas industrial enterprises.
