API 5CT Grade L80 pipes are specified into three product specifications levels namely PSL1, PSL2, and PSL3. This tube is formed from high quality raw material and uses the latest technology to bring utmost precision and safety. The carbon steel alloy pipes are manufactured in a seamless and welded form with wall thickness ranging from SCH 40 to SCH 160. Also, the pipe comes with a personalization option with different diameters, dimensions, sizes, lengths, and more.
The tube is made in different shapes like round, square, rectangular, and more. The chemical composition of carbon, manganese, titanium, sulfur, nickel, phosphorus, chromium, and molybdenum add resistance to various crevice corrosions and prevent pitting. The chromium acts as a skin to the base iron and gives protection from rusting and cracking while the molybdenum or moly component helps the metal to withstand various conditions and also provides workability in aqueous conditions.
This high category carbon steel pipes are utilized in various commercial sectors for different applications. The material is widely used in high pressure systems and under high temperature conditions. The mechanical properties plays a vital role in overall structure retention and strength has a minimum yield potency of 552 MPa and minimum temple strength of 655 MPa. This mechanical property gives good formability and ductility to the metal.
Industries like oil and gas refineries, petrochemical industry, water supply, fertilizer, sugar, food processing, power generation, onshore and offshore services are some of the many applications where the API 5CT Grade L80 seamless pipes are widely used in their day to day usage
