ASME SA312 TP201 is a specification for seamless stainless steel pipes that are used in high-temperature and corrosive environments. It is specifically designed for pipes made from stainless steel grade 201. The "TP" in the specification designation stands for "Tube, Pipe," indicating that it is applicable to both seamless tubes and pipes.ASME SA312 is a standard developed by the American Society of Mechanical Engineers (ASME) that outlines the requirements for seamless, welded, and heavily cold-worked austenitic stainless steel pipes for various industrial applications.
ASME SA312 TP201 seamless pipes are manufactured following the guidelines and requirements set forth in the ASME SA312 standard. These pipes are produced without any welded joints, ensuring a continuous and seamless structure.The pipes are made using the cold-drawn or hot-finished process, depending on the requirement of the client.
The ASME SA312 TP201 Seamless Pipe is made of high-quality stainless steel that ensures excellent resistance to corrosion and oxidation. It is designed to withstand extreme temperatures, high pressures, and harsh environments, making it the perfect choice for use in chemical and petrochemical plants, oil and gas pipelines, and other demanding applications.201 seamless pipe has a smooth surface finish, which provides excellent resistance to the accumulation of dirt and other contaminants. This feature makes it easy to clean and maintain, ensuring a long service life while reducing the need for maintenance.
The size range of ASME SA312 TP201 seamless pipes is from ½” to 24” in diameter, with wall thickness varying from SCH 10 to SCH XXS. The ASME SA312 TP201 seamless pipe is widely used in various industries such as chemical processing, food and beverage, petroleum refining, pharmaceuticals, and many more.
