ASTM A312 TP316L is a grade of seamless and welded stainless steel pipe that is highly resistant to corrosion, especially in chloride-rich environments. Some key details about A312 TP316L pipe:
Material Composition: TP316L stainless steel has a lower carbon content compared to TP316, making it more resistant to intergranular corrosion and better suited for welding applications. The composition includes 16-18% chromium, 10-14% nickel, and 2-3% molybdenum.
Mechanical Properties: TP316L pipe has a minimum tensile strength of 485 MPa (70 ksi) and a minimum yield strength of 170 MPa (25 ksi). The minimum elongation is 35%.
Sizes and Schedules: A312 TP316L pipe is available in sizes from 1/8" NB to 48" NB, with wall thicknesses ranging from Schedule 5S to Schedule 160. Common sizes include 1/2", 1", 2", 4", 6", and 12" NB.
Manufacturing: The pipes can be produced as seamless or welded (ERW). Seamless pipes are made through a process that does not involve welding at any stage. Welded pipes use an automatic welding process with no filler metal added.
Applications: Due to its excellent corrosion resistance, A312 TP316L pipe is widely used in the chemical processing, petrochemical, marine, and other industries that require piping systems to handle corrosive fluids and environments.
NACE MR0175, also known as ISO 15156, is a widely recognized international standard developed by the National Association of Corrosion Engineers (NACE) International. This standard provides requirements and recommendations for the selection and qualification of materials for equipment used in oil and gas production environments where sour (containing hydrogen sulfide) service conditions are present.
Here are some key points regarding NACE MR0175: Sour Service Environments, Material Selection, Material Qualification, Compliance, Global Recognition.
NACE MR0175 is a vital standard that helps to ensure the safe and reliable operation of equipment in sour service environments by providing guidelines for the selection and qualification of materials that can withstand the challenges posed by hydrogen sulfide and related contaminants.
