The maximum percentage composition of carbon in the construction of the ASTM A249 TP316L pipe is 0.035%, as it is a low-carbon type of TP316 stainless steel pipe. There is an improvement to its resistance to intergranular corrosion after welding, which doesn't affect the intergranular corrosion resistance of the alloy and its properties.
● Improved Weldability: Low carbon percentage enables the prevention of the precipitation of carbides during welding, thereby protecting the heat-affected zone from corrosion.
● Great Corrosion Resistance: Works well against pitting as well as crevice corrosion, especially in chloride conditions. Hence, it is durable for marine and chemical uses.
● High-Temperature Endurance: Excellent strength and stability retention at high temperatures. Hence, it can be used in thermal applications.
● Standard Compliance: This applies to specification ASTM A249 and, therefore, can be depended upon in terms of quality.
In the marine, chemical processing, and pharmaceutical sectors, ASTM A249 TP316L pipes seem to be the most appropriate. Additionally, they are particularly useful in:
● Heat Exchangers and Condensers: These pipes can withstand corrosive fluids for the effective optimisation of processes and the maximisation of equipment's useful life.
● Boiler and Superheater Tubes: These pipes have the capability to withstand high temperatures and pressure necessary for the generation of steam and energy.
● Pipelines: They can be used in the transportation of corrosive materials, which is why welding is crucial in ensuring the safety and integrity of the entire system.
